Color Modes
Your
computer monitor emits light and uses the three color
regions of RED, GREEN, and BLUE to reproduce the colors
we see. On the other hand, in print, we try to reproduce
the colors we see with ink (cyan, magenta, yellow,
and black). In printing, when we are mixing (adding)
inks together the colors might vary slightly due to
a difference between output devices. Below is a better
description of two color modes most commonly used,
RGB and CMYK:
RGB color
One of the color spaces used in graphics software.
This color space is based on the primary additive
colors of Red, Green, and Blue. This is the most common
color mode used in graphics software.
Please
submit your files to us in RGB
Why?
RGB has a larger color gamut with more information
as you can see from the color chart on the right.
The Eco-SoL inkjet printer we use is actually better
at describing CMYK from your RGB file then if you
convert the file yourself.
CMYK color
One of the color spaces used in graphics software.
This color space is based on the ink colors used in
traditional full-color commercial printing: Cyan,
Magenta, Yellow, and blacK. In general, it is best
to edit your images in RGB color mode because many
software features and commands will not be available
in CMYK mode. Although your inkjet printer may use
these four colors of ink, you do not need to convert
images to CMYK for printing on consumer-level desktop
inkjet printers. In the case of desktop printers,
the RGB to CMYK conversion is handled by your printer
driver.
