Dear List,
I defined the following color for one of my documents: \definecolor[P][r=0.64,g=0.22,b=0.27] When I printed this document on a probably typical office laser printer (a Canon iRCXXXX), the colors didn't match. (not even close and I didn't like the printed color) This is probably no real surprise, but can anybody provide some insight or hints to information on these matters to me:
-- Are "spot colors" the thing to use to get a grip on these matters?
no, as your printer uses process colors (cmyk)
-- Is this generally only a matter of "color spaces" and transformations between them? or ...
indeed, often printer drivers apply some paper properties as well
-- Is this also dependent on specific printer models (eg. different office laser printers)?
yes, toner vs ink, kinds of paper, quality of renderer etc
-- If yes, is there any source on information on the pecularities of these printers?
specifying in cmyk might help Hans ----------------------------------------------------------------- Hans Hagen | PRAGMA ADE Ridderstraat 27 | 8061 GH Hasselt | The Netherlands tel: 038 477 53 69 | voip: 087 875 68 74 | www.pragma-ade.com | www.pragma-pod.nl -----------------------------------------------------------------
