atril prints cmyk PDF with inverted colors

[Borut Mrak]

Hello,

Since upgrading to Ubuntu 18.04, I'm having trouble printing PDFs in CMYK colorspace from atril.

The same PDFs printed OK with atril on the same machine when on 17.10, they print OK on other machines with 16.04 (with evince though), and they also print OK on 18.04 from command line (lpr -P PRINTER_NAME file.pdf). I was only able to reproduce the issue with atril.

The printer is a HP LaserJet Pro 400, also tried on a Lexmark E260dn, so it's not a printer or driver issue (different printer manufacturers).

I do not want to post the PDFs in the bug report, but I can send them privately. They are 100% CMYK (/DeviceCMYK) as are the included images.

Please contact me if there is any further information needed or anything I can try, I'm very interested to resolve this as it interferes with my workflow a lot.

Best regards,
Borut Mrak

It didn't occur to me earlier, but I just tried installing evince and printing with it and it has the same problem, so this is probably bug in a library they both use.

I don't know where to reassign it and would really appreciate help in determining this information.

Same here, for documentation purposes, you can list the images embedded in a pdf with

`pdfimages the_document.pdf -list`
.

It affects all pdf processing for me (even if printing the document to file or opening it in gimp).

The only "process workaround" so far is to open the document in libreoffice draw and print it from there :( .

Probably the same issue, but with more information and a sample document: https://bugs.launchpad.net/ubuntu/+source/evince/+bug/1560286 .

It is indeed the same issue, I tested the -proposed packages for libcairo from bug #1560286 and they fixed the bug.
