RGB is the standard model for computer monitors in which red, green and blue are added together to create a full-color light spectrum. CMYK uses cyan, magenta, yellow and black pigments to create the full-color spectrum. CMYK is the standard four-color process for offset printing. Unfortunately, some printers are not compatible with RGB color image files. If your printer will not accept RGB images and you need to convert it to the CMYK format, you can convert your file in minutes online, without downloading or purchasing any software. Most graphics-editing software programs can also convert RGB files to the CMYK mode. Tips Writer Bio
