<h3><a name="strip"></a>Strip reading instruments</h3>
When used with a <span style="font-weight: bold;">DT20</span>, <span
style="font-weight: bold;">DTP41</span>, <span
style="font-weight: bold;">DTP51</span>, <span
style="font-weight: bold;">Eye-One Pro<span style="font-weight:
bold;"> </span></span>or <span style="font-weight: bold;">ColorMunki</span>
strip reading instrument, chartread will first establish
communications with the instrument, and then set it up ready to read
the strips. The strips are labeled A to ZZ, and for each strip it
will prompt:<br>
<br>
About to read strip XX :<br>
<br>
where XX is the strip label, and this is followed by the available
options to navigate, read the strip, or finish. Note that the normal
(forward) direction of strip reading is one that starts at the strip
label.<br>
<br>
For the <span style="font-weight: bold;">DTP51</span> you should
feed the strip into the instrument, and the microswitch will trigger
the read.<br>
<br>
For the <span style="font-weight: bold;">DTP41</span> you should
line the appropriate strip up in the machine, and press its button.<br>
<br>
For the <span style="font-weight: bold;">Eye-One Pro</span> you
should set the guide to the appropriate strip, place the instrument
<span style="text-decoration: underline;">ahead</span> of the first
patch on blank paper, and then press and hold the instruments
button. When you hear a beep from the computer, you can then move
the instrument steadily over the patches, releasing the button after
the instrument is past the last patch. Moving the instrument too
fast or changing speeds may cause a mis-read, or a scan with few
samples read per patch.<br>
<br>
For the <span style="font-weight: bold;">ColorMunki</span> with the
default chart, the patches are the same width as the silver portion
of body (white version), or the textured portion of the body (black
version). Place aperture of the the instrument (located at its
center) in the white space ahead of the first patch, and then press
and hold the instruments button. When you hear a beep from the
computer, you can then move the instrument steadily over the
patches, releasing the button after the instrument is past the last
patch. Moving the instrument too fast or changing speeds may cause a
mis-read, or a scan with few samples read per patch. For the <span
style="font-weight: bold;">high density</span> ColorMunki chart (<a
href="printtarg.html#h">printtarg -h</a>), the patches are
arranged so that three rows are exactly the width of the body
of the instrument. If you are careful you can use this to guide the
center of the instrument over each row, or you may prefer to use
something like a plastic ruler to help guide the instrument.<br>
<br>
Using the <span style="font-weight: bold;">DTP20</span> or the <span
style="font-weight: bold;">Eye-One Pro</span> or <span
style="font-weight: bold;">ColorMunki</span> with a randomized
chart layout, the strip may be scanned from either direction. If a
randomized chart layout has not been used for the <span
style="font-weight: bold;">Eye-One Pro</span> or <span
style="font-weight: bold;">ColorMunki</span>, then the chart
should only be read in the one direction (use <a
href="chartread.html#B">chartread -B</a>).<br>
<br>
Note that you may have to check that system alert sounds are enabled
and at a suitable volume to in order to hear the beep prompt. For
the Eye-One Pro and ColorMunki, a second beep will sound after a
successfully read strip, or a double beep will sound,
indicating a failure or warning that needs attention. See also the
note on Linux in <a href="Installing_Linux.html">installation</a>.<br>
<br>
If the strip is read successfully there will be a single "success"
beep, and the line will be followed with:<br>
<br>
Ready to read strip XX : <br>
Strip read OK<br>
<br>
If there is an error of some sort there will be a double "fail"
beep, and a message will be issued, and you will be asked whether to
abort the chart reading, or retry the<br>
failed strip:<br>
<br>
Ready to read strip XX : <br>
Strip read failed due to misread (Not enough
patches)<br>
<br>
Hit Esc to give up, any other key to retry:<br>
<br>
If you are unable to successfully read a strip after several
retries, you can skip that strip using the <span
style="font-weight: bold;">'n'</span> key, and save<br>
the chart readings without that strip.<br>
<br>
If the strip is read successfully, but the patches values don't seem
to be what is expected, you will get a double "fail" beep and
the following type of warning:<br>
<br>
Ready to read strip XX :<br>
(Warning) Seem to have read strip YY
rather than XX !<br>
Hit Return to use it anyway, any other key to
retry, Esc, ^C or Q to give up:<br>
<br>
This could be because you have accidentally read the wrong strip (a
common mistake), or it could be that the device response is so
different from what is expected that warning is erroneous, or you
may get a lot of these sorts of warnings if you are accidentally
reading the wrong chart. You may also get this sort of warning if
you are not using bi-direction reading (chartread -B), and read the
strip from the wrong end.<br>
If you are absolutely sure you lined up the correct strip, then hit
return, otherwise line the appropriate strip up again, and hit some
other key (ie. space).<br>
Erroneous warnings are less likely if a previous profile for a
device was given to <span style="font-weight: bold;">targen</span>
to set more accurate expectations.<br>
<br>
You may also see the following type of warning:<br>
<br>
Ready to read strip XX :<br>
(Warning) Patch error YY.YYY (>35 not good,
>95 bad)<br>
There is at least one patch with an very unexpected
response!<br>
Hit Return to use it anyway, any other key to
retry, Esc, ^C or Q to give up:<br>
<br>
Similar to the previous warning, this indicates that while the right
strip appears to have been read, one of the patch readings is quite
different to what is expected. This may indicate an error of some
sort (ie. damaged test chart, or bad instrument positioning), or may
be erroneous if the actual device response is quite different to the
expectation. Erroneous warnings are less likely if a previous
profile for a device was given to <span style="font-weight: bold;">targen</span>
to set more accurate expectations.<br>
<br>
You can also navigate the next strip to be read using the <span
style="font-weight: bold;">'f'</span> key to move forward and the
<span style="font-weight: bold;">'b'</span> keys<span
style="font-weight: bold;"></span><span style="font-weight: bold;"></span>
to move backwards. The prompt will indicate whether this strip has
already been read or not, or whether all strips have been read. You
can also use <span style="font-weight: bold;">'n'</span> to move
forward to the next unread strip. After each successful reading it
will move forward to the next unread strip. When you are finished,
use the <span style="font-weight: bold;">'d'</span> to indicate
that you are done. You can choose to finish before all the strips
are read, and the patches that have been read will be saved to the
.ti3 file. This is useful if you are unable to read a particular
strip successfully, or if you are unable to finish the chart in one
session, and you can later <span style="text-decoration:
underline;">resume</span> reading the chart by using the <span
style="font-weight: bold;">chartread -r</span> flag. [You could
resume reading the chart patch by patch using the <span
style="font-weight: bold;">chartread -r -p</span> if you are
unable to read a strip successfully.]<br>
<br>
When reading in patch by patch mode, there are a few additional
navigation options, such as <span style="font-weight: bold;"><span
style="font-weight: bold;">F</span></span> to move forward 10
patches, <span style="font-weight: bold;">B</span> to move
backwards 10 patches, and <span style="font-weight: bold;">g</span>
to go to a specific patch.<br>
<br>
You can abort the whole process at any time by hitting Escape, and
the readings will not be saved.<br>
<br>
<hr style="width: 100%; height: 2px;">
<h3><a name="xy"></a>X-Y Table instruments</h3>
When you are using an XY table type instrument, such as a Gretag <span
style="font-weight: bold;">SpectroScan</span>, chartread
will first establish communications with the instrument, and then
set it up ready to read the chart. You will be prompted for each
sheet with a message such as:<br>
<br>
Please make sure that the white reference is in
slot 1, then<br>
place sheet 1 of 4 on table, then<br>
hit return to continue, Esc to give up<br>
<br>
After hitting return you will be prompted to line up three squares
on the sheet, one at a time:<br>
<br>
Using the XY table controls, locate patch A1 with
the sight,<br>
then hit return to continue, Esc to give up<br>
<br>
On completing this, the instrument will commence reading each sheet.<br>
<br>
<hr style="width: 100%; height: 2px;">
<h3><a name="spot"></a>Spot reading instruments</h3>
When used with a <span style="font-weight: bold;">DT22</span> or <span
style="font-weight: bold;">SpectroLino</span> or use the patch by
patch reading mode (<span style="font-weight: bold;">chartread -p</span>)
with the <span style="font-weight: bold;"></span> <span
style="font-weight: bold;">Eye-One Pro<span style="font-weight:
bold;"> </span></span>or <span style="font-weight: bold;">ColorMunki</span>
instrument, or use the external values mode (<span
style="font-weight: bold;">chartread -x</span>), chartread will
first establish communications with the instrument, and then set it
up ready to read the patches. The patches are typically labeled by
column A to ZZ, and row 1-999. Each patch will prompt:<br>
<br>
Ready to read patch 'XX' :<br>
<br>
where XX is the patch label, and this is followed by the available
options to navigate, read the strip, or finish.<br>
<br>
Place the instrument on the indicated patch, and trigger a reading
using one of the available methods (typically using the instrument
switch of pressing a key).<br>
<br>
There should be an audible prompt on a successful or failed reading.
<br>
<br>
Note that you may have to check that system alert sounds are enabled
and at a suitable volume to in order to hear the beep prompt. For
the Eye-One Pro and ColorMunki, a second beep will sound after a
successfully read strip, or a double beep will sound,
indicating a failure or warning that needs attention. See also the
note on Linux in <a href="Installing_Linux.html">installation</a>.<br>
<br>
If the patch is read successfully, the line will be completed with:<br>
<br>
Ready to read patch XX :<br>
Patch read OK<br>
<br>
If there is an error of some sort, a message will be issued, and you
will be asked whether to abort the chart reading, or retry the<br>
failed patch:<br>
<br>
Ready to read patch XX : read_strip
returned 'Strip misread' (Bad reading)<br>
<br>
Strip read failed due to misread<br>
Hit Esc to give up, any other key to retry:<br>
<br>
You can navigate the next patch to be read using the <span
style="font-weight: bold;">'f'</span> key to move forward and the
<span style="font-weight: bold;">'b'</span> keys<span
style="font-weight: bold;"></span><span style="font-weight: bold;"></span>
to move backwards, while <span style="font-weight: bold;">'F'</span>
and <span style="font-weight: bold;">'B'</span> will move forward
and backwards by 10 patches. The prompt will indicate whether this
patch has already been read or not, or whether all patches have been
read. You can also use <span style="font-weight: bold;">'n'</span>
to move forward to the next unread patch. When you are finished, use
the <span style="font-weight: bold;">'d'</span> to indicate that
you are done. You can choose to finish before all the patches are
read, and they will be saved to the .ti3 file. This is useful if you
are unable to finish the chart in one session, and you can later <span

chart by using the <span style="font-weight: bold;">chartread -r</span>
flag.<br>
<br>
You can abort the whole process at any time by hitting Escape, and
the readings will not be saved.<br>

<span style="font-weight: bold;"></span>
<hr style="width: 100%; height: 2px;">
<h3><a name="displaytype"></a>Display Type<br>
</h3>
Many of the colorimeters have a <span style="font-weight: bold;">display
type</span> selection parameter. Depending on the instrument, this
may combine two related functions: 1) Changing the measurement mode
to suite either refresh-type, or non-refresh displays, and 2)
Changing the calibration to suite a particular displays spectral
characteristics.<br>
<br>
A refresh type display uses a technology that presents different
portions of the image at different times, doing so at a high enough
rate that this is normally imperceptible. This time varying
characteristic can interfere with measuring a display color, unless
the instrument makes allowances for it, typically by making its
measurement period a multiple of the display refresh period. Display
types that <span style="font-weight: bold;">refresh</span> are CRT
(Cathode Ray Tube), Single chip DLP (Digital Light Processing) and
Plasma displays. An example of a <span style="font-weight: bold;">non-refresh</span>
display technology is LCD (Liquid Crystal Display), although is a
few cases the back-light illumination may have a low enough
frequency flicker to benefit from the refresh mode.<br>
<br>
Instruments in which the display type selection only changes the
measurement mode (i.e. i1d3), will typically have some other
independent option to set the calibration type. Simpler instruments
combine the measurement mode with a calibration selections,
typically refresh+CRT and non-refresh+LCD. Some instruments are a
hybrid of both (Spyder4), where the display type can select between
generic refresh/non-refresh that can then use a .CCSS to set the
calibration type, or a combined selection of non-refresh and a
particular display type.<br>
<br>
See <a
href="http://en.wikipedia.org/wiki/Comparison_of_display_technology">Comparison_of_display_technology</a>
for some background on different display technologies.<br>

<br>
<img style="width: 272px; height: 243px;" alt="" title="ColorMunki

<br>
</span><span style="font-weight: bold;">Availability:<br>
<br>
</span>The <span style="font-weight: bold;">ColorMunki</span> <span
style="font-weight: bold;">Design or Photo </span>from <a
href="http://www.xrite.com/">X-Rite</a> is currently
available in two different packages from the manufacturer. These
packages differ in what features the manufacturers software
provides, as well as cosmetic differences between the instrument
(white and black). This comparison <a
href="http://www.colormunki.com/product/show?page=2">chart</a>
illustrates the differences. Used with Argyll, there are no
differences in operation of a ColorMunki instrument, irrespective of
which package it came with. The ColorMunki Design has the lowest
RRP, but the Photo package may be cheaper with discounting .<br>
<br>
<span style="font-weight: bold;">Limitations & Features:</span><br>
<br>
Unlike the Eye-One Pro, the ColorMunki is only available in a U.V.
Cut (Ultra Violet filtered) model. This means that it is not
suitable for use with the Fluorescent Whitener Additive
Compensation option in Argyll (see <a href="FWA.html">here</a> for
a discussion about what FWA compensation is).<br>
<br>
Like the Eye-One Pro, this instrument does support the <a
href="spotread.html#H">high resolution</a> spectral mode.<br>
<br>
<span style="font-weight: bold;">OS X and X-Rite drivers</span><br>
<br>
Please note the installation <a
href="Installing_OSX.html#ColorMunki">instructions</a>.<br>
<br>
<span style="font-weight: bold;">Tips & Tricks:<br>
<br>
</span>In handling the instrument when about to make a reading, be
very careful not to accidentally press the switch - it is large and
easily pressed by accident. A guide of some sort (ie. a plastic
ruler) can help a lot in keeping the instrument over a line
of patches. <br>
<br>
<span style="font-weight: bold;">Patch recognition:</span><br>
<br>
For the best chances of good patch recognition, the instrument
should be drawn smoothly and not too rapidly over the strip. (This
can be a little tricky due to the two small rubber feet on the
bottom of the device that aid its spot reading guide.) If there is a
misread, try slowing down slightly. Generally a higher quality set
of readings will result if slower scans are used, since there will
then be more samples averaged for each patch. <br>
<br>
In <a href="chartread.html">chartread</a>, the -<span
style="font-weight: bold;">T ratio</span> argument modifies the
patch consistency tolerance threshold for the ColorMunki. In
recognizing patches in a strip, the instrument takes multiple
readings as the strip is read, and then divide the readings up into
each patch. It then check the consistency of the multiple readings
corresponding to each patch, and reject the measurement if they are
too inconsistent. For some media (ie. a coarser screens, fabric
etc.) the default tolerance may be unreasonably tight, so the <span
style="font-weight: bold;">-T ratio</span> argument can be used to
modify this criteria. To loosen the tolerance, use a number greater
than 1.0 (ie. 1.5, 2.0). <br>
<br>
Note that <a href="printtarg.html">printtarg</a> provides the <a
href="printtarg.html#h">-h</a> option that allows the choice of
two different patch row widths with ColorMunki test charts. [Some
people have successfully used the i1Pro patch layout with the
ColorMunki, by making a guide to keep it over the much narrower
patchs.]<br>

<a name="DTP20"></a></span><span style="font-weight: bold;">DTP20
"Pulse" reflective spectrometer<br>
<br>
</span><span style="font-weight: bold;"><img title="DTP20" alt=""
src="DTP20.jpg" style="width: 304px; height: 210px;"><br>
<br>
</span><span style="font-weight: bold;">Availability:<br>
<br>
</span>The <span style="font-weight: bold;">DTP20</span> from <a
href="http://www.xrite.com/">X-Rite</a> was discontinued during
2007, but may still be available from old stock or second hand. <br>
<br>
<span style="font-weight: bold;">Special features:</span><br>
<br>
The <span style="font-weight: bold;">DTP20</span> has a couple of
unique features that Argyll can take advantage of. One is that it
can operate un-tethered (off line). A whole chart can be read
un-tethered by first clearing any previous readings in the
instrument, then reading the chart TID strip, before reading all the
other strips. The instrument can then be connected up to <span
style="font-weight: bold;">chartread</span>, which will recognize
the chart, and download all the measurements.<br>
If there is no chart in the instrument when chartread connects to
it, then it will use the strip by strip tethered mode, just like the
other strip instruments. If the right number of spot readings are
present in the instrument, these will be used by <span
style="font-weight: bold;">chartread</span> too.<br>
<br>
Un-tethered spot measurements can also be read in using <span
style="font-weight: bold;">spotread</span>, which will notice the
stored readings, and offer to print them out, or they can be
ignored, and tethered readings taken. This will clear any saved spot
readings.<br>
<br>
<span style="font-weight: bold;">Note</span> that tethered (on-line)
strip reading will only work if the firmware in the device is
version 1.03 or greater. You can check the firmware version by
running with the verbose option: <span style="font-weight: bold;">-v<br>
<br>
Chart printing:<br>
<span style="font-weight: bold;"><br>
</span></span>Because the DTP20 measures exact distances using the
markings on its ruler, it's critical that the chart be printed out
exactly the right size. If the chart gets re-sized at all in the
process of printing it, the DTP20 is likely to fail in reading it.
If you have a problem with this, you might want to increase the page
margins using the <span style="font-weight: bold;">printtarg -m</span>
parameter, or find a printing path that preserves the test chart
size correctly.<br>
<br>
<span style="font-weight: bold;"><span style="font-weight: bold;"></span></span><span
style="font-weight: bold;">Operation:<br>
<br>
</span>When reading in tethered (on-line) mode, that the instrument
takes <span style="font-weight: bold;">several seconds</span> to
download the measurements after each strip, and that the indicator
will be in "rainbow" mode while this occurs. <span
style="text-decoration: underline;">Wait</span> until the
indicator turns solid green again before starting to measure the
next strip.<br>
<br>
To <span style="font-weight: bold;">reset</span> the instrument and
clear any stored readings: press the button three times in quick
succession. The indicator will turn solid blue. Then hold the button
down until the instrument beeps and the indicator goes out. Release
the button and the indicator should flash then return to solid green
(ready).<br>
<br>
To <span style="font-weight: bold;">calibrate</span> the
instrument, place it on its calibration tile, then press the button
three times in quick succession.The indicator will turn solid blue.
Click the button another three times in quick succession, and the
indicator should turn yellow. Then hold the button down until the
instrument beeps and the indicator goes out. Release the button and
the instrument should flash and then turn solid green.<br>
<br>
If the chart is particularly <span style="font-weight: bold;">small</span>,
the patches may end up printed very close to the edge of the chart,
and therefore it may be difficult to confine your scan to the chart,
and passing<br>
the instrument over the edge of the chart may prevent it reading
successfully. One way of working around this is to place the chart
on a larger piece of paper of the same type.<br>
<br>
The <span style="font-weight: bold;">speed</span> of scan can be
quite critical with this instrument. In particular, it doesn't work
very well if the scan is too <span style="font-weight: bold;">slow</span>.
You don't want to go too fast either, as this reduces the number of
samples per patch.<br>

</span><span style="font-weight: bold;">Availability:<br>
<br>
</span>The <span style="font-weight: bold;">Eye-One Pro</span> from
<a href="http://www.xrite.com/">X-Rite</a> (was Gretag MacBeth) is
available in two packages from the manufacturer. These packages
differ partly in what accessories come with the instrument, but
primarily in what features the manufacturers software provides. This
comparison <a
href="http://www.xrite.com/product_overview.aspx?ID=812">chart</a>
illustrates the differences. Used with Argyll, there are no
differences in operation of an Eye-One Pro instrument, irrespective
of which package it came with. The lowest cost package is the <a
href="http://www.xrite.com/product_overview.aspx?ID=1461">i1 Basic
Pro</a>.<br>
<br>
The EFI ES-1000 (which is a re-badged Eye-One Pro) is also reported
to work with Argyll.<br>
<br>
Unless you know what you're doing, and have a very specific reason
to buy an instrument fitted with a UV (Ultra Violet) filter, make
sure that you buy an instrument without the filter. A UV filtered
instrument can't deal intelligently with FWA (Fluorescent Whitener
Additive) effects in paper. (Look <a href="FWA.html">here</a> for
more information about FWA compensation.) You can emulate a UV cut
instrument quite well in Argyll by using FWA compensation mode, and
supplying a UV filtered D50 illuminant spectrum (ie.
ref/D50_0.0.sp).<br>
<br>
There have been three revisions of the Eye-One Pro, Rev. A, B and D.
The rev D is capable of sampling twice as fast as the Rev. A and B
versions of the instrument, and is also available with an ambient
light reading capability.<br>
<br>
<span style="font-weight: bold;">NOTE</span> for those running on
Linux with a Rev. D, there is a problem with the current (as of Feb
2008) Linux USB stack that causes the instrument to stop working
once it has been used. The only workaround is to unplug and replug
the instrument in again, whereupon it can be used one time again. A
fix for this problem will probably turn up in the Linux 2.6.26
kernel release.<br>
<br>
See also <a href="i1proDriver.html">How can I have confidence in
the i1pro Driver ?</a><br>
<br>
<span style="font-weight: bold;">Patch recognition:</span><br>
<br>
For the best chances of good patch recognition, the instrument
should be drawn smoothly and not too rapidly over the strip. If
there is a misread, try slowing down slightly. The Rev A and B.
instruments have a slower sampling rate than the latter revision
instruments, and hence must be used a bit more slowly. Generally a
higher quality set of readings will result if slower scans are used,
since there will then be more samples averaged for each patch.<br>
<br>
In <a href="chartread.html">chartread</a>, the -<span
style="font-weight: bold;">T ratio</span> argument modifies the
patch consistency tolerance threshold for the Eye-One Pro. In
recognizing patches in a strip, the instrument takes multiple
readings as the strip is read, and then divide the readings up into
each patch. It then check the consistency of the multiple readings
corresponding to each patch, and reject the measurement if they are
too inconsistent. For some media (ie. a coarser screens, fabric
etc.) the default tolerance may be unreasonably tight, so the <span
style="font-weight: bold;">-T ratio</span> argument can be used to
modify this criteria. To loosen the tolerance, use a number greater
than 1.0 (ie. 1.5, 2.0). <br>
<br>
<span style="font-weight: bold;">Differences between reading modes:<br>
<br>
</span>The spotread -d mode uses a fixed integration time, choosing
1 of 3 depending on the display brightness. The advantage of this is
that the readings are all consistent (there can be no mismatch of
sensitivity due to integration and/or gain changes), and the dark
level is calibrated at the exact integration time used.<br>
<br>
The spotread -e or -a modes are adaptive, so the range of brightness
is much greater, but the measurement time will be variable, and the
dark level<br>
is interpolated. The adapative mode can be used with dispcal and
dispread by using the -V flag, and this may give better results for
displays capable of very deep blacks.<br>
<br>
<span style="font-weight: bold;">Special features:</span><br>
<br>
A feature unique to Argyll when used with the Eye-One Pro, is the
high resolution spectral mode. This returns spectral measurements at
3.333 nm spacing, rather than the default 10nm spacing, and also
extends the range of wavelengths slightly. This high resolution may
assist in giving better accuracy for "peaky" emissive sources such
as illuminants and displays. The high resolution mode is selected by
using the <span style="font-weight: bold;">-H</span> flag on the
command line to <span style="font-weight: bold;">dispcal</span>, <span
style="font-weight: bold;">dispread</span>, <span
style="font-weight: bold;">chartread</span>, and <span
style="font-weight: bold;">spotread</span>. It can also be toggled
on and off within <span style="font-weight: bold;">spotread</span>
using the <span style="font-weight: bold;">h</span> key. The
extended range down to 350nm may give some information about an
illuminants ultra violet content, although the accuracy of the
readings between 350-380, and 730-740nm should not be relied upon.<br>

with more limited software from the manufacture, and takes a
noticeably longer time to make most measurements (a minimum of 1
second), but both instruments will take longer for very dark
samples, and under these conditions the speed difference is less
significant.<br>
<br>
The i1Display Pro <a
href="http://xritephoto.com/ph_product_overview.aspx?id=1454&catid=109">package</a>
comes with i1Profiler, and the instrument is generally faster than
the ColorMunki Display, but other than this and the software
package, the instruments appear to be virtually identical.<br>
<br>
Both instruments are capable of using CCSS (<a

Sample</a>) files, and this also gives the instrument the
capability of using a non-default standard observer. CCSS files can
be created using the <a href="ccxxmake.html">ccxxmake</a> tool, and

<br>
This instrument cannot function without the driver software having

This firmware is not provided with Argyll, since it is not available
under a compatible license.<br>
<br>
The purchaser of a Spyder 2 instrument should have received a copy
of this firmware along with their instrument, and should therefore
be able to enable the Argyll driver for this instrument by using the
<a href="spyd2en.html">spyd2en</a> tool.<span style="font-weight:

<span style="font-weight: bold;">Linux USB hub problems:<br>
<br>
</span>Note that the Spyder doesn't appear to operate at all well on
Linux if attached to a secondary USB hub. Note that you may have
such a secondary hub built into your motherboard. If Argyll has
difficulty in reliably talking to the Spyder, try connecting it
directly to the computer, rather than via a usb hub, or try using a
USB port on your computer that connects directly to a root hub. This
is probably due to a bug in the Linux EHCI driver, and a fix is due
to appear in the Linux kernel sometime after July 2011. The name of
the fix is "EHCI: fix direction handling for interrupt data
toggles".<br>

readings to a CRT refresh, and you can no longer remove the LCD
filter, reducing its sensitivity compared to the Spyder 2 in CRT
mode. The Spyder 2 or one of the other instruments may be a better
choice if you particularly need to measure CRTs.]<br>

</span>The <span style="font-weight: bold;">Spyder4Elite</span>, <span
style="font-weight: bold;">Spyder4Pro</span> and <span
style="font-weight: bold;">Spyder4Express</span> are a currently
available instruments. The manufacturer <a
href="http://www.colorvision.com/">DataColor</a>, appears to be
hostile to the use of these instruments under Linux, so it is
probably best to look at one of the other colorimeters, unless you
already happen to have a Spyder 4 that you want to use. The <span
style="font-weight: bold;">Spyder4Elite</span> and <span
style="font-weight: bold;">Spyder4Pro</span> appear to be
identical hardware with different software from the manufacturer.
The <span style="font-weight: bold;">Spyder4Express</span> lacks

These instruments are capable of using using CCSS (<a
href="File_Formats.html#ccss">Colorimeter Calibration Spectral
Sample</a>) files, and this also gives the instrument the
capability of using a non-default standard observer. CCSS files can
be created using the <a href="ccxxmake.html">ccxxmake</a> tool
using a spectrometer as a reference.<br>
<br>
<span style="font-weight: bold;">Important Note </span>about the
DataColor Spyder 4 vendor display type/calibration support:<br>
<br>
This instrument does not have a full range of display type
calibration selections available without the vendor supplied
calibration data for it.<br>
This calibration data is not provided with Argyll, since it is not
available under a compatible license.<br>
You can use CCSS files as an alternative (see above), or as the
purchaser of a Spyder 4 instrument you should have received a copy
of the calibration data along with their instrument, and should
therefore be able to enable the full range of display type
selections in Argyll by using the <a href="spyd4en.html">spyd4en</a>
tool.<br>

The accuracy of this instrument does not seem to be comparable to
the commercial instruments when used for measuring displays,
particularly in the area of measuring dark colors, and I've seen the
best results when used with a CRT display. It may well give good
results in calibrating projectors, since this was what it was
designed to do.<br>
