I am intending to upload some images to the Digital Arts Prints at the R'osity Marketplace but I need some help with colour management. I've searched through the forum archives for info on CMYK and printing and although I've learnt some things I'm still unsure on some points. Below is an extract in part from the submission guidelines for digital art in the Marketplace: File Format: All files should be in CMYK color space. Images left in RGB color space can shift color as much as 10-30%. The following file formats are acceptable for printing: -.JPEG -.TIFF -.PSD -.PDF Gloss Laminated Prints are 150 gm Satin Photobase with 5 ml lustre overlaminate. Canvas is 17 ml coated artist canvas with spray fix to lock in color. Paper is semi-archival paper and will last forever. My questions. After converting an RGB image to CMYK it displays fine in PS but varies markedly in other programs (in depth of contrast and swings in colour tint). Is there some standard/setting that I can use for determining that my image as displayed in PS(6)is as it will appear at R'ositys printers? Shane
