Matching colors
The process of matching device output color to your computer screen is quite complex
because printers and computer monitors use different methods of producing color. Monitors
display colors by light pixels using an RGB (red, green, and blue) color process, but printers
print colors using a CMYK (cyan, magenta, yellow, and black) process.
The following factors can influence your ability to match printed colors to those on your
screen:
● print media
● device colorants (inks or toners, for example)
● printing process (inkjet, press, or laser technology, for example)
● overhead lighting
● programs
● printer drivers
● computer operating system
● monitors
● video cards and drivers
● operating environment (very humid or very dry)
● personal differences in perception of color
Keep these factors in mind when colors on your screen do not perfectly match your printed
colors. For most users, the best method for matching colors on your screen to your device is
to print sRGB colors. The device uses sRGB and automatically optimizes color output.
