Servus (Greetings) Andreas, Ummmmm, I didn't think that I'd respond to this learned forum so soon after introducing myself ... however: Several have written: C = _C_yan M = _M_agenta Y = _Y_ellow and K = blac_K_ and this is entirely correct. _B_ is irrelevant, otherwise _B_ Blue, Brown, Beige, Burgundy, Buff, the list goes on. Similarly the others. You'll note that there is no other colour description in common use for any of "C", "M" or "Y"? Now, why did the inventors of those "colours" name them as such, d'you think? ;) Oh, RGB has relevance on a monitor, but not in (Offset or Lithographic) printing. The fact is that, in printing (I'll carefully here say standard printing as distinct from hexachrome and extra spot colours) CMYK is what we employ and always have to reproduce the illusion of a photograph on a white substrate. The technique of CMYK printing evolved in the late 17th Century. I have a cookbook I adore (German actually, Andreas) of 1906 vintage with colour plates. In those days "etching" those plates, indeed etching plates before computer technology, was an enormously expensive exercise even when it was simply a blac_K_ plate when such an expert spent maybe a week (depending on complexity and size) on each of the -C-M-Y-K- plates. Today? It's interesting that many print houses still charge more for colour separation of photographs when that, today is often a keystroke, than typesetting, which still takes an operator to whom you have to pay a salary. Sorry, may be OT, in which case our Mum will surely advise me accordingly. :) Incidentally, did you know that black, white and greys are not actually "colours"? Except, possibly, the jury is still out, when it's "rich" black? >-) Cheers, Christian =============================================================== GO TO http://www.prodig.org for ~ GUIDELINES ~ un/SUBSCRIBING ~ ITEMS for SALE
