Importing SpyderPrint (Datacolor 1005) readings with Argyll 1.4.0

[f***@public.gmane.org]

Hello everyone, just subscribed.

First of all, a big thank to Graeme Gill for
this impressive toolset.
I already use Argyll to profile my scanners, with
great results.

Now I'd like to profile my printer.
I have a Spyder3Print
colorimeter (Datacolor 1005), which I use under Windows.
I don't need to drive
it with Argyll (I know it's not supported); I'd just like to use its
measurement file (it's XML), saved from its Datacolor SpyderPrint 4.2.1
software, to build an ICC profile with Argyll.

From what I gathered, I first

need to build a .CHT file from the (synthetic, so to say) TIFF target charts
supplied with its software; "scanin -g <..>" should do the trick.
Then, I
should find a way to convert the XML measurement file, which is like this:

<?
xml version="1.0" standalone="yes"?>
<NumVals>463</NumVals>
<RefWhite>9230 119
-398</RefWhite>
<RefBlack>153 -12 233</RefBlack>
<LabColor>1 626 -243 -95
</LabColor>
<LabColor>2 854 673 -3420</LabColor>
<LabColor>3 1141 1430 -4952
</LabColor>
<LabColor>4 1362 2113 -6057</LabColor>
[...]

to a suitable format
which Argyll may understand (.ti3 ?).

A this point, with the .cht and
measurement file, using "colorprof" I should be able to build the ICC profile.


So the main question is:

Any hint about converting that XML measurement file
into something Argyll can use?

Is the .cht generated by "scanin -g" from the
(original synthetic) TIFF targets OK for Argyll, or is there something else I
should provide? Maybe the original LAB values of the patches?

Or maybe I
didn't get something obvious, and the process is even simpler? :-)

Thanks
anyone,

Fernando

Hello everybody,
I'm in the same point as Fernando last year. A few months ago I was
preparing how to profile the printer and I found a few messages of this thread.
Today I find only this message. Please, Is there any document explaining
the process?

Best regards,
Juanjo

Hi,
the Datacolor 1005 is not directly supported. I'm not sure exactly what
you are attempting - can you provide some more detail ? i.e. is there a Datacolor
measurement file that you wish to import ?

Hi,
Thanks a lot for write me as quickly. I'll try to explain better
with my horrible english, sorry.

I was studying how to profile my printer (Epson Stylus PRO 3800 ) a
few months ago. I was going to buy refillable cartridges and I wanted to
begin to learn how make good profiles seriosly.
I have a Spyder 3 kit and I'm not very happy with it. For the
displays I never had good profiles and for the printer... I printed
always greenish pictures. At this momnet I can't buy other hardware.

I check your software to calibrate a pair of displays and, for the first
time, I had very similar colors in both displays.
After that I was looking for printer calibration and I readed that you
helped Fernando to "translate" from a xml file with patch readings from
spyder software to the .ti3 format.

Yesterday I was playing with your software. I make a small target page
and I printed it . I readed the patches with the spyder 3 software and
I have an xml file.
I have a ti1 and ti2 files but I'm lost with the ti3 format.

I remember your messages between Fernando Carello and you about the same
problem but now only I find the first message.

Do you have any document that explain how to do the migration? If there
isn't software made for this I can program a script for this.

Best regards,
Juanjo


P.S. I readed that somebody was trying to read the data from the device
but I only saw a month of messages. I can help with this if it's possible.

Hi,
using a different profiler may not help, if it turns out that the accuracy of
the instrument is the issue.

Yesterday I was playing with your software. I make a small target page and I printed it .
I readed the patches with the spyder 3 software and I have an xml file.
I have a ti1 and ti2 files but I'm lost with the ti3 format.

If you email me a sample xml file, then I might be able to create a tool to
translate it to a .ti3.

Do you have any document that explain how to do the migration? If there isn't software
made for this I can program a script for this.

The .ti3 file format is documented here <http://www.argyllcms.com/doc/ti3_format.html>,
and you can create dummy files using fakeread <http://www.argyllcms.com/doc/fakeread.html>

P.S. I readed that somebody was trying to read the data from the device but I only saw a

Someone mentioned that it was probably easier than I was assuming, but it's hard to
justify working on such an old, spot by spot instrument. I understand that the
more recent DataColor instruments will read a strip at a time, but I don't have
one of these to work on.

That someone would be me :)

I figured out what most of the USB commands do, but I haven't put
together a driver for it yet. The words "copious spare time" spring to
mind ;)

Once I get my act together and finish the code, it should be fairly
simple to add support for it.

Thanks,
