RGB eller CMYK printer?

Jeg må indrømme at jeg også studsede da jeg læste spørgsmålet. Jeg mente heller ikke at RGB eksisterede på printere. Det gør det som farveprofiler - ICC, men det er jo bare et konverteringsfilter.

Men ved at læse lidt rundt omkring på nettet, fandt jeg bl.a.:

Purchase a Postscript RIP.
For me this has not yet been necessary - my color results have been good enough without having to spend the extra money for a RIP (Rasterizing Image Processor). I am considering doing this in the near future because it would eliminate one of the last little problems with my color workflow, which is this: the Epson 2200 is an RGB printer, not CMYK (or CcMmYKk with the 7-inks), out of the box. Which means that it takes what you see on the screen in RGB color mode and converts it to the print CMYK space at print time in the driver. Well, the proper workflow is to work in CMYK mode in your graphics program so that there is no color conversion at print time, leaving less room for surprises. You have better control over the final output this way because you can manage and control the CMYK conversion up-front.

In order to implement a pure-CMYK workflow, you need a RIP. The RIP gives you some additional benefits, which are a) improved ICC color profiles, b) true Postscript printing capabilities, c) industrial print-workflow and job management capabilities, useful in facilities with high-volume printing needs.

You can spend as much as you want to spend on a RIP for your Epson, from ~$200 for the Epson 'STYLUSPHOTO2200 Rip Pro Softwa' all the way up to a dedicated RIP Server for thousands of dollars. There are RIPs on the market that target very specific applications like fine-art or B&W photography printing. It can be expensive, but it is required if you want to run a professional setup or get the absolute best results for your photographic printing application.

Desuden er http://www.design.upenn.edu/comp/help/faqs/Printing/Epson2200Color-Managed-Workflow.pdf også interessant.

Og fra Epson selv fandt jeg denne: http://www.epson.co.jp/e/newsroom/tech_news/tnl0411single.pdf

Så meget tyder på at visse af Epsons modeller faktisk arbejder i RGB (med sRGB farveprofilen), forudsat at man kører med PostScript RIP Board.

Så trykkeren har åbenbart ret.

Du får som grafiker nok en del mere ud af at læse det, end mig. Jeg forstår ikke halvdelen af det :-)

Læg et svar - og tak. Vi blev klogere *S*

Har desuden købt noget kalibreringsgrej (EyeOneProf), og den siger også at det er en RGB printer jeg har *S*

Ja, men jeg bliver da også selv klogere hele tiden :-) Og DET er jo ikke så dumt endda...
