Callas has published an article on prepress automation in label printing. The following topics are covered in depth:

In addition, the importance of the ISO standard “Processing Steps” (ISO 19593) in prepress files for labels is pointed out.
FOGRA has completed the research project Professional colour communication in multiprimary printing that aims to derive important requirements for a predictable and professional workflow for industrial multicolor printing. This includes the development of a test suite, which, together with its documentation and evaluation matrix, simplifies the comparison of current applications for the preparation and processing of multicolor objects. Furthermore, a multicolor printing grid is to be developed based on the analysis of typical multicolor systems across printing processes.
Furthermore, an exchange color space for retouching and separation of multicolor print objects (CMYKOGV) will be developed and introduced as part of an ISO standard:
Martin Bailey gives some thoughts on the Global Graphics blog about compliance, compatibility, and why some tools are more forgiving of bad PDFs.
He reports on Global Graphics’ nearly 25 years of experience with native PDF RIPs (Harlequin). At that time, developers were faced with the question of whether to strictly implement the PDF specification and thus risk not being able to process many PDFs (even from well-known creators), or whether to pragmatically achieve the best possible result even with poorly built PDFs.
Some time ago I reported on a solution for a problem with the PDF/X export in InDesign CC 2019.
With the update to InDesign 14.0.1 released on 19.11.18 (according to Adobe) the problem should also be solved.
Now, several readers have recently reported that the problem has reappeared in the latest version CC 2021 (version 16.1). (Unfortunately I can currently not reproduce the problem since I have to stick with an older MacOS version because of customer project.)
