What is CMYK color mode?
CMYK is the color mode used by PsPrint to reproduce your job on one of our presses. The color calibration of Cyan (C), Magenta (M), Yellow (Y), and Black (K) determines the final color in your artwork. As a result, your submitted files must be in CMYK color mode to maximize color quality. If your files are submitted using any other color standard, such as RGB or Pantone, they will be converted to CMYK during preflighting. Conversion from one color standard to another may cause colors to shift. Before submitting your artwork files, you may want to review our file preparation guidelines. If you are not familliar with printing in CMYK color mode, we highly recomend that you order a hard copy proof, which can be selected for most PsPrint products. Please note that we can not guarantee that the color of your artwork printed on our presses will match that seen on your monitor or printed via any other method. More information about CMYK.
