Color Profiles in lmtx

Color Profiles in lmtx

[juh]

[-- Attachment #1.1: Type: text/plain, Size: 2195 bytes --]

Hi all,

again I have a question concerning color profiles.

I have this to load the ISO Coated v2 300% profile. 

\setupbackend[
   format=PDF/X-3:2003,
   intent={ISO Coated v2 300\letterpercent\space (ECI)},
   ]

\setupcolors[cmyk=yes,rgb=no,]

But is this profile part of the new lmtx version?

I get this in my logs

backend         > profiles > profile specification 'ISO Coated v2 300% (ECI)' loaded from '/home/juh/context-linux-64/tex/texmf-context/colors/icc/context/colorprofiles.xml'

But I am not sure whether the profile is really loaded.

In the old context distribution I had to put the profile in texmf-local.

There is this in lmtx:

~/context-linux-64/tex/texmf-context/colors/icc/profiles$ ls -l
insgesamt 3652
-rw-r--r-- 1 juh juh     416 Jan  6 16:32 default_gray.icc
-rw-r--r-- 1 juh juh    1992 Jan  6 16:32 ecirgb_v2.icc
-rw-r--r-- 1 juh juh     700 Jan  6 16:32 ecirgb_v2_iccv4.icc
-rw-r--r-- 1 juh juh 1829093 Jan  6 16:32 isocoated_v2_300_eci.icc
-rw-r--r-- 1 juh juh 1829077 Jan  6 16:32 isocoated_v2_eci.icc
-rw-r--r-- 1 juh juh    3144 Jan  6 16:32 srgb.icc
-rw-r--r-- 1 juh juh   60960 Jan  6 16:32 srgb_v4_icc_preference.icc

I am not sure if the file name matches as in profiles.xml we have this with
mixed upper and lower cases:

 <profile>
        <filename>ISOcoated_v2_300_eci.icc</filename>
        <colorspace>CMYK</colorspace>
        <class>prtr</class>
        <id>FOGRA39</id>
        <info>ISO Coated v2 300% (ECI)</info>
        <checksum>e14f5db955711d914d877df35ad7a1b5</checksum>
        <version>24000000</version>
        <url>http://www.color.org</url>
        <outputcondition>Offset printing, according to ISO 12647-2:2004/Amd 1, OFCOM, paper type 1 or 2 = coated art, 115 g/m2, tone value increase curves A (CMY) and B (K)</outputcondition>
</profile>

Is there a linux tool to test if the correct profile is part of the pdf?

Any hints?
TIA
juh

Hi juh,

I guess the problem are the file names of the profiles. On Windows it
doesn't matter if you use upper or lower case letters. AFAIK Linux
handles that differently.
In the end the <filename> entries in
  "[..]/texmf-context/colors/icc/context/colorprofiles.xml"
and the real file names must be "equal" for all OS.

Add

\enabletrackers[backend.pdfx]

to your document to get more info about the profile inclusion.
Not sure if this is the correct tracker though... no time to check, as I
have to make lunch now.


Hope that helps,

Peter

I just realized that the above output is the right output.

Ok. But now I have another question

I want to install a new profile I downloaded from eci.org

I extended colorprofiles.xml putting it in
texmf-local/colors/icc/context/ with this additional xml:

    <profile>
        <filename>PSO_Uncoated_ISO12647_eci.icc</filename>
        <colorspace>CMYK</colorspace>
        <class>prtr</class>
        <id>Custom</id>
        <info>PSO Uncoated ISO12647 ECI</info>
        <checksum>ae81087e1c54c6fdda2f93bd2d47cfaf</checksum>
        <version>2000000</version>
        <url>http://www.eci.org</url>
        <outputcondition>Commercial and specialty offset, paper type 4,
uncoated white paper, positive plates, tone value increase curves C
(CMY) and D (K), white backing.
        </outputcondition>
    </profile>

I generated the md5 checksum from the file PSO_Uncoated_ISO12647_eci.icc.

But the file in texmf-local is not found

backend         > profiles > profile specification 'PSO Uncoated
ISO12647 ECI' not found in 'colorprofiles.xml, colorprofiles.lua'

How can I make context aware of the files?

TIA
juh

Hi Jan Ulrich,

you might check profiles that with VeraPDF (or simply \nopdfcompression
as first command in the source and search for the profile 😎),

How about deleting the cache (simply remove
tex/context-cache/luatex-cache) and generate it again (by running
"mtxrun --generate", before compiling your source again?

I hope it helps,

Pablo

I get the error that was reported in another thread. :-(

resolvers       | resolving | warning: no lua configuration files found
resolvers       | resolving | no texmf paths are defined (using TEXMF)

.sh ./install.sh was the solution.

I cannot use mtxrun in a way like "mtxrun --locate" in lmtx:

Just tried to do the same and after some fiddling it worked.
I used this settings for the profile (slightly modified)

<profile>
        <filename>PSO_Uncoated_ISO12647_eci.icc</filename>
        <colorspace>CMYK</colorspace>
        <class>prtr</class>
        <id>Fogra47L</id>
        <info>PSO Uncoated ISO12647 (ECI)</info>
        <checksum>ae81087e1c54c6fdda2f93bd2d47cfaf</checksum>
        <version>2000000</version>
        <url>http://www.eci.org</url>
        <outputcondition>Commercial and specialty offset, paper type 4,
uncoated white paper, positive plates, tone value increase curves C
(CMY) and D (K), white backing.
        </outputcondition>
    </profile>


Copy the icc-profile into the same folder as the shipped profiles. Call
"context --make" to make a new format, update the file database.
