I'm writing an application which should analyze a PDF page and tell based on the toner prices and other costs how much does this page cost. The problem here is that I don't know how colors are mixed in the printer (using CMYK model).
Suppose I have one pixel filled with magenta, then I have the same pixel with the colour which is exactly half magenta and half yellow. Is a toner consumption same in both cases? Or there is twice as much toner used in the second case?
Is black toner used for anything else than grey? For example really dark blue?
I need to get page price, based on grey/colour percentage. I have typical manufacturers data (toner price, number of pages with certain toner coverage, that can be printed).
