Reply To: Convert images to CMYK

RGB is fine, but if you have to print it, it becomes a CMYK question. I think you have to decide what the output will be before starting. Using RGB images in an RGB workflow os ok, but not for printing. A lot of people get disappointed when looking at the results when the conversions went the wrong way. I rarely use the specific CMYK values in logo’s, pantone colors a much better choice. Pantone Bridge ca help you when it has to be converted anyhow. The “preserve number” is very important too in the conversion proces. What the pdf-standards in adobe do is fine, but no completely correct. The sites I mentioned above (and surely some others) indicate clearly what to do and how to do it.
As professional,I think it’s our concern to make the best possible pdf for print or web. Fiddling with conversions in Photoshop before importing images can be avoided by using to right conversion standards in Indesign. A lot of people are not familiar with Photoshop, so it can get worse in stead of better. If an image has a profile attached, change it or use it, if it has none, the output will always never be good.
Of course, I’m only using European standards as I live in Belgium.
