Re: The black problem

Thanks for taking the time to experiment with me.
It's weird, eh?!

I'm outputting to Adobe Acrobat Pro 8 pdf.
I do test prints to my Oki Laser but that's just for dummy outputs.
PDF is set for CMYK composite.

Still waiting for them to tell me they can't afford 32 pages of color so I
can ignore this issue for now :-)...but you know...once yer on a quest it's
difficult to waiver.

BUT...this is also visible from the printer's output of last year's
publication.

First thing is to make sure that your Advanced Printer Settings are set to
output CMYK Composite, and that you're outputting to a suitable PostScript
printer. Otherwise, Publisher converts from the document's CMYK to RGB,
which suffers from the same issue as on-screen, and then the printer has
to convert it back to CMYK for the press.

I just ran some tests viewing Adobe Reader's preview, using a 0,0,0,100
AutoShape, a 100,100,100,100 AutoShape, and a black PNG created in Paint.

Outputting to PrimoPDF in CMYK had both AutoShapes the same colour, but
the image somewhat lighter (WTF?)
Outputting to PrimoPDF in RGB looked exactly like Publisher's preview; the
overprinted AutoShape darker than the black only AutoShape but lighter
than the image.
Outputting with Publisher's PDF output (with Printer Settings set to CMYK
and the PDF options set to Commercial Press) gave the overprinted
AutoShape the same colour as the image, but the black-only AutoShape a
lighter shade.
Outputting with Publisher's PDF output (with Printer Settings set to RGB
and the PDF options set to Print) gave the same.

I don't have the tools (or at least the know-how) to check what colour
space any of these PDF files are in, unfortunately.
