I have a document which has color on about 25% of its pages. When I print it in the copy shop, the printer's technically supposed to recognize the b/w pages. However, all pages are registered as colored, i.e. the pages are color-enabled pages which happen to not have any colors on them (but I'm paying for the color-enabled-ness). Regrettably, the staff have to charge me for color because the printer's leased and they have to pay for color pages, so showing them that there's no color doesn't help me.

What are possible sources for b/w pages showing up like that?

This question came from our site for users of TeX, LaTeX, ConTeXt, and related typesetting systems.

How have you generated the PDF file? Which color package and color models you are using? What kind of images are on the b/w pages? – Heiko Oberdiek Sep 19 '12 at 21:15
This looks off-topic to me: there's no TeX in the question, and it's really not clear that it's anything that can be solved at the TeX end. – Joseph Wright Sep 21 '12 at 6:19
@JosephWright - should've said it's a pdflatex document in the first place, will also add further info as requested by Heiko. Agree that it may be a non-tex problem, but may be a misconfiguration on my side in the tex code as well, might be worth finding out. – user46627 Sep 21 '12 at 10:50
This question would fit on SuperUser with more detail, and they are better-placed to answer it than we are. Could an edit be made to 'flesh out' the issue, and I can then migrate. – Joseph Wright Sep 22 '12 at 19:54

Perhaps not the answer you want to hear:

I. Part:

You can build two pdf files by your own.

  • One containing all colored pages,
  • one containing all bw pages.

Be very carefully when you have to print doublesided.

Now you can print them separatly, but you have to sort them after printing. Be sure to print the colored and the blach and white part on the same paper (normally the paper for colored pages differs to paper for bw pages in a copy shop).

II Part:

Perhaps your copyshop uses an Xerox Colorcube printer? This printer can be configured that a page with for example a small colored logo is printed as black and white. It depends on the color percentage rate (for example 10%) of the page to be printed as black and white. The printer can check it and print the page as black and white or colored. So the price is automatic calculated and you got your document printed on only one paper grade.

Just ask your favorite copyshop.

The monochrome option for xcolor can reveal useful for this application. – egreg Sep 19 '12 at 23:00
Thanks - doesn't really help in my special case, though. Option I doesn't work because the document is indeed supposed to be printed double-sided and I'd end up printing way too much in color after all. Option II would be perfect but fails due to lack of Colorcube-enabled copyshops around me – user46627 Sep 20 '12 at 10:04
@Nicolas78: Then please follow Heikos request and give us more information as he asked you. – Kurt Sep 22 '12 at 23:12
