Custom marks that you create require an EPS and PDF version of the image. You select the EPS image file when creating a custom mark, and the corresponding PDF file is automatically included in the output. EPS marks can optionally be included with PJTF or JDF output.

Image files for the following custom mark types are included in the Preps software:

• Registration marks
• Short- and long-side guides
• Bender mark for NELA plate-bending system, to help ensure accurate positioning on the cylinder
• Color bar duplicating marks (located in the Dupmarks folder)
• In-RIP color ID marks in various rotations
• Digital exposure test mark
• Device resolution text mark
• Collation marks (available as PostScript only)
• Bar code marks for WST and Müller Martini (MM) equipment (available as PostScript only)
• Micro Dot and Micro Dot Double marks

To use PostScript-based marks such as the collation marks and bar code marks, you must enable the Output PS marks flats for PJTF/JDF option on the Output tab in the Preferences dialog box. When outputting PDF mark flats, PDF-based marks must be saved as PDF version 1.4 or lower.
