Re: [photoshop-beginners] colors



The triangle you may see indicates that that color is not 'print safe'.  Monitors make colors with light...the more you add, the brighter the color...'additive', in other words.  Printers are subtractive....colors get darker if more is added.  Using print-safe colors will help you get the same on paper as you do on your screen.
 
It's best to work your documents in CMYK, too....rather than RGB....

Good luck

Yes, I got really confused when you posted that Keith because I thought (rightly so) that all ink jet printers were CMYK, and they merely translated RGB to CMYK ink colors.. Wouldn't it be more accurate to just work in photoshop in CMYK and then print it to a CMYK printer?

I keep getting errors on my paint swatch that say (triangle) "Warning: Out of gamut for printing."

If the printer can print a certain color like pure blue for its nozzle check, why can't it print that color from a photoshop image?

I never understood (and still don't) all the color management and translation policies.

Which is what you said, now that I reread the post. Point being,
though, you should be working in RGB if your output is to be
printed using an inkjet printer.
