If a deviceRGB image is lying completely outside of trim and bleed, and the PDF/X output intent is set to CMYK, should a preflight flag this as an error according to ISO1590-7:2010 or not? I have tools that currently do this. If I read chapter 126.96.36.199 of ISO 15930-7:2010, I'm not really sure that is what these preflight app's should do:
Device colour spaces may be used for print elements only if:
⎯ they match the space specified in the PDF/X output intent; or
⎯ the PDF/X output intent specifies a CMYK print characterization, and the device colour space is DeviceGray.
All input to help me solve this puzzle is more than welcome.
Looks like I was confusing the Ghent Workgroup specs (and their use of TrimBox to define an area for print elements) with the PDF/X-4 standard which clearly (6.1.3) says that anything drawn on the page is a print element.
Sorry for the confusion.
> anything drawn on the page is a print element.
And that may include objects that are lying completely outside trim or bleed, right (just to be sure :-)?
