Expand the custom marks (.mrk) usability and documentation.
We are able to create custom marks files (.mrk) but I have not found much documentation. Detailed documentation would go a long way especially with a few examples. I would also like an easier way to create these files without so much trial an error (GUI).
I would like to create black only registration, page info and crop marks. Additionally, the ability to adjust spread pages fold marks offset and the ability to create center lines on the pages in the bleed area would be great.
