Frequently Asked Questions:
What should I know about color?
Digital files
can be saved in different color models, and the one you need depends
on how you will be using your image.
RGB
This color model is used for on-screen viewing. Graphics for websites and emails
should be saved in the RGB color model. Just like your TV, your computer
screen uses light to make color. Red, Green and Blue light combine to make
all other color combinations. Things that will be printed should not be saved
as RGB files, with the exception of images that will be used in Microsoft
Office products, which should be saved at 150 dpi in RGB.
CMYK
If your image will be printed using full color (or 4-color), this is the color
model you need. CMYK stands for Cyan, Magenta, Yellow and Black. These four
ink colors can be combined to form (almost) any color. Your desktop printer
uses the CMYK model for printing, so images that you would like to print
should be saved in CMYK. (The exception is images that will be placed into
Microsoft Office software – see RGB model above). Traditionally, four
color printing is the most expensive, but today, there more cost effective
ways to print in four color.
Pantone (PMS) or Spot Color
The Pantone color model is used for spot color printing. This is printing that
uses 1 or more designated PMS colors. The colors you can print are limited
to the exact PMS colors you choose. |
