Summary0008902: Preflight Verifier - RGB black text
DescriptionI am requesting "Check for RGB black text" option in Preflight Verifier to avoid generating text with over than pure CMYK black color.

Additionally there should be option in text importer for automatically apply pure CMYK black to all imported text.

It is specially important working with text from web.

As I was requesting this feature I have made it ;-)
Patch for Preflight Verifier warning is attached (1.3.9).
It add warning if text with any RGB or registration colour is found.

In fact this check only for "Printer" output has any sense. But PV is invoked before PDF output dialogbox appears, where we can change target of output.
For me this warning is not very big problem.

Also I dont think this feature need on/off switch in PV preferences, but if someone need it - it can be done. But till now I dont know how to save settings, so I dont include this in patch.

Sometimes text has more than 100% K:

What about Headlines with a deeper black (e.g. 50% C and 100% K)?

This feature has as main goal to check document for RGB Black texts pasted into documents from internet content - web sites and email. Often (if not always) these includes has text with RGB Black which prints very ugly in CMYK (not 100K but like black from images in all CMYK plates).

It would be nice if the checker would find RGB colors everywhere rather than just in text. Examples would include RGB images without color profiles, RGB colors in graphical elements and so on.

This is something i would not put in the preflight verifier : the same way RGB values can be converted to CMYK by the exporter when choosing 'printer' target, text using RGB black could be fixed automatically by the exporter.
