Working with Color

Spot and process colors
Spot and process colors correspond to the two main ink types used in commercial printing.
A process color is printed by combining the four standard CMYK process inks: cyan, magenta,
yellow, and black. By blending these inks in varying proportions, the printer can reproduce
most colors.
A spot (or custom) color is a special premixed ink that is used with, or instead of, CMYK process
inks. A spot color requires its own plate on the press.
The difference between the two types of color is that process colors are printed as four-color
separations, corresponding to the four process inks. Spot colors do not need to be separated, since
a spot color is printed on a single plate.
FreeHand comes with several color libraries that you can import in whole or in part into your
drawings. For more information, see “Editing colors” on page 161.
Color spaces
Color spaces are methods for defining colors in a computer application. Each color space has
different benefits and drawbacks depending on whether you plan to present a drawing online or
in print. The color space you choose also becomes important when you import or export artwork.
In FreeHand, you can define colors using four methods:
•
CMYK color components represent the process inks used in four-color printing.
•
RGB (red, green, and blue) is used for onscreen display, including web and multimedia design.
RGB values range from 0 to 255 for each color.
•
HLS (hue, lightness, and saturation) color mode produces RGB colors. This system is
useful for picking different colors with similar values (for example, highly saturated colors of
different hues).
•
The System Color Picker (Windows) and the Apple Color Picker (Macintosh) display the
colors installed in the operating system. The System Color Picker lets you choose from 48 basic
Windows colors. The Apple Color Picker lets you define colors as CMYK, RGB, HLS, HSV
(hue, saturation, value); you can choose from the 60-color Crayon picker or the 216-color Web
HTML picker.
