Hello, I'm making an image library for people to download printing quality Tiff images from a Web Page. I guess the prefered image format in the printing business is CMYK, so I wondered, is it possible to save/convert RGB Tiffs to CMYK in Gimp? Also, could someone tell me how to calculate DPI of an image? I have not managed to figure this DPI system out, for example, if an image is a 100×50 pixels, what's the DPI?? Please kindly CC any reply to my return address, since I'm not a subsbriber of the Gimp Developer list. Thanks for the advice! Thanks, kati@xxxxxxxxxxx
