[NTG-context] Color Profile ISO Coated v2 300% (ECI) not found anymore

Dear all,

the color profile  ISO Coated v2 300% (ECI) is not found anymore

Dear Jan-Ulrich,

my guess is that color profiles might be have been replaced.

Here there might be some background:

  https://www.pragma-ade.com/general/manuals/standards.pdf#search=unset

In any case, these are the profiles in current latest:

$ find context -name *.icc
texmf-context/colors/icc/profiles/colo-imp-cgats001compat-v2-micro.icc
texmf-context/colors/icc/profiles/colo-imp-isocoated_v2_eci.icc
texmf-context/colors/icc/profiles/colo-imp-sgrey-v2-magic.icc
texmf-context/colors/icc/profiles/colo-imp-srgb-v2-magic.icc
texmf-context/colors/icc/profiles/colo-imp-srgb.icc
texmf-context/colors/icc/profiles/colo-imp-sgrey-v4.icc
texmf-context/colors/icc/profiles/colo-imp-srgb-v4.icc
texmf-context/colors/icc/profiles/colo-imp-default_gray.icc

And these are the ones from November 2024 latest:

$ find .backup-context/11012024_context/ -name *.icc
texmf-context/colors/icc/profiles/colo-imp-isocoated_v2_eci.icc
texmf-context/colors/icc/profiles/colo-imp-srgb.icc
texmf-context/colors/icc/profiles/colo-imp-srgb_v4_icc_preference.icc
texmf-context/colors/icc/profiles/colo-imp-default_gray.icc

Just in case it helps,

Pablo

Sorry, Jan-Ulrich, it isn’t clear to me what is going on here.

The following sample:

  \setupbackend
    [format=PDF/X-3:2002,
     intent={ISO Coated v2 (ECI)}]
  \starttext
   \null
  \stoptext

gives me the following error:

  lpdf-fmt.lmt:282: attempt to call a nil value (global 'urls')

Line 189 from the same file reads:

  -- When we have an URL we can assume that embedding is not needed.

Line 8 from colorprofiles.xml also reads (as a comment):

    When the id is "Custom" we assume that embedding is needed.

(Also related to line 391 from lpdf-fmt.lmt.)

As far as I understand, color profiles with urls aren’t being embedded
in the PDF document.

For reasons totally unknown to me, lpdf-fmt.lmt has also problems with
profiles from http://www.color.org.

I’m afraid I cannot help here,

Pablo

fixed in next upload (the file was zipped as text so it got this 
linefeed changing that is/was needed for unix but it's a binary file; 
actually that normalizing was needed decades ago but i'm not sure if it 
still is needed; for tex it doesn't matter if there's cr lf or crlf (mac 
linux windows); for a similar reason we had to add \endinput to the end 
of files but again one can wonder if that matters now)

Many thanks for checking this, Max.

I didn‘t know that it was possible to check color profiles.

> No idea if this will fix the issue with ConTeXt, but it's worth a try.

As far as I know, unless the color profile contains "<id>Custom</id>" in
`colorprofiles.xml`, it will not be embedded in the PDF document.

BTW, inspecting the PDF code from the following source,

  \setupbackend
    [format=PDF/X-3:2002,
     intent={ISO Coated v2 300\letterpercent\space (ECI)}]
  \setuppagenumbering[location=,]
  \starttext
   \null
  \stoptext

I get these two objects:

  2 0 obj
  <<
    /ProfileCS (cmyk)
    /ProfileName (ISO Coated v2 300% \(ECI\))
    /URLs [ <<
          /F (http://www.color.org)
          /FS /URL
        >> ]
  >>
  endobj

  3 0 obj
  <<
    /OutputConditionIdentifier (FOGRA39)
    /S /GTS_PDFX
    /Type /OutputIntent
  >>
  endobj

Reference to object #3 is contained in object #7, but I cannot find any
reference to object #2.

Hans, I may be missing something, but object #2 seems orphan to me.

Could you check this?

Many thanks for your help,

Pablo

when you also define profile=... to contain it, it will be referenced, 
so i might need to check and not embed the reference when it's not used; 
irr validators complain with some mix of internal and excernal anyway

Many thanks for your reply, Hans.

I found out just by reading it (only this human validator involved 😅).

But the Arlington PDF model validator complains about `/Extensions` in a
PDF-1.3 document.

It seems extensions are available beginning with PDF-1.7
(https://github.com/pdf-association/arlington-pdf-model/blob/master/tsv/latest/Catalog.tsv).

Since I don’t know any PDF/X validator, I’m not sure whether extensions
might be allowed in that case.

Many thanks for your help,

Pablo

Though I see a new profile I still get the same error.

This is in my local colorprofiles.xml

<profile>
         <filename>ISOcoated_v2_300_eci.icc</filename>
         <colorspace>CMYK</colorspace>
         <class>prtr</class>
         <id>FOGRA39</id>

     </profile>

My definition:

\setupbackend[
    %format=PDF/X-1a:2001,
    %format=PDF/X-1a:2003,
    format=PDF/X-3:2002, %Empfehlung von Flyeralarm
    %format=PDF/X-3:2003,
    %format=PDF/X-4,
    %format=PDF/X-4p,
    intent={ISO Coated v2 300\letterpercent\space (ECI)}
    ]

My profile in textmf-local...:

-rw-r--r-- 1 juh juh 1,8M 15. Feb 2022  ISOcoated_v2_300_eci.icc

I checked the File checksum. It it correct.

The names of the profiles in tex-context differs.
colo-imp-cgats001compat-v2-micro.icc  colo-imp-icc.rme 
colo-imp-sgrey-v2-magic.icc  colo-imp-srgb.icc 
colo-imp-srgb-v4.icc
colo-imp-default_gray.icc             colo-imp-isocoated_v2_eci.icc 
colo-imp-sgrey-v4.icc        colo-imp-srgb-v2-magic.icc

All names start with colo-...

But in colorprofiles.xml all these names are missing.

Sorry, but I am quite confused.

juh

We could strip the prefix when checking ... do you have a test that 
exposes this issue?
