I’m finishing the editing on my book that includes my photos of stained glass works. I’m self-pubing this and was told by my printer that I need to convert my tiff images from RGB to CMYK in order to present printer with ‘trouble-free’ files, thus keeping cost of printing down. QUESTION: A friend suggested that I get Adobe photshop to do this conversion, WHICH IT DOES DO..But…The photos seem to obtain a kind of dullness when this conversion is done. Am I doing this right? Thanks

RGB is a screen format CMYK is specificaly a print format, in essence the blacks are not printed from an ink but created using the other inks. As its a format for inks it look ‘off’ on screen, they look very wierd but will print up just fine.

Wrong: in CMYK, black is a separate ink (it’s the "K" in CMYK)
