- Its presets include Digital press, Offset CMYK and KDP, but the page says mark geometry is illustrative until a print shop specifies it.
Field notes
The workspace lists a 50 MB PDF limit and describes inspection as local, with decoded content capped at 256 MB and image rendering at 40 megapixels; it states there is no page-count cap. Presets include Digital press, Offset CMYK, KDP, and Custom, with editable published defaults of 300 DPI and 0.25 pt. KDP selects 0.125-inch bleed, while mark geometry remains illustrative pending the print shop’s specifications.
