How can I fix "gsicc_open_search(): Could not find" Error message while using gs

Question

I am trying to fix my pure black colored text problem in PDF conversion. I am able to convert my sRGB pdf to CMYK pdf but text colors are not kept in pure black. I already tried to use ghostscript: convert PDF into CMYK preserving pure Black for text trick but even I compiled "apple_..." files in my current directory, I always get :

gsicc_open_search(): Could not find ~/temp/AdobeCPs/CMYK/apple_to_jNP_neutrals.icc .

the command I am using:

gs -q -sDEVICE=pdfwrite -o sample.pdf -sColorConversionStrategy=CMYK -sSourceObjectICC=control.txt test.pdf

My output is :

 ./base/gsicc_manage.c:1088: gsicc_open_search(): Could not find Graphic_RGB apple_to_jNP_neutrals.icc    0   1   0

Could you help ?

Answer 1

Even though this is a quite old thread it seems not yet solved. I had the same error as mentioned above with blanks as separators in the control.txt instead of tabs (as mentioned in the Ghostscript version Color Management WhitePaper). Changing to tabs fixed the problem for me.

Answer 2

Your command line and input file isn't relevant to the problem, the failure is during startup:

| ./base/gsicc_manage.c:2731: gs_setsrcgtagicc(): cannot find srctag file While reading gs_lev2.ps:

gs_lev2.ps is part of Ghostscript's startup code. That's all executed before you even get to the point of reading the command line options.

You haven't said which version of Ghostscript you are using, on which OS, or where you got it from, but it looks to me like you version is fundamentally broken.

I infer from your text that you are using version 9.18, that's 5 versions (2.5 years) out of date, the current version is 9.23. I'd suggest you get the vanilla Ghostscript source from the downloads page and compile that.
