Hi everyone, We are currently supporting a very old version of 32 bit adobe reader on our ubuntu 22.04/kde desktops, due to the requirement for support for a PDF feature called "Overprint" which is used by our label printing supplier (I work for an Australian winery)
https://pdfa.org/understanding-overprint/ The result of the lack of Overprint support can be seen in this example pic: https://photos.app.goo.gl/Be2piuVtjbZqWyoX6 This is the source pdf used in the examples: https://drive.google.com/file/d/1WGlly-EvzQl1Jhj39R9hvJ16CIgVZD5j/view?usp=sharing There are no open source PDF viewers that support this feature, and we are interested in sponsoring development for it in Okular (if required). We did find Linux/non-adobe support in a proprietary viewer called PDF Studio Pro: https://www.qoppa.com/pdfstudio/ Is this feature something Okular would be interested in developing? Regards, Bernard Gray
