I am attempting to bring images from digital cameras into QuarkXPress for Windows (v5.01). The quality is terrible when I go to produce a PDF file or try to print it. My limited understanding is that this is because these are JPG images in RGB format. Do I need to convert them in some way before bringing them into QuarkXPress? Should I convert them to JPG CMYK, or TIFF, or something else? If so, what is the best way to do this? Thanks for your help!
