Color Primer
This appendix covers concepts that are basic to printing in color,
including:
• Properties of color
• Printing techniques
• Effective use of color
• Raster images and vector graphics
• File optimization for processing and printing
If you are already familiar with color theory and digital color
printing, you can skip to the last section

The properties of color
This section introduces concepts that are basic to color theory.
You will encounter some of these concepts (such as hue,
saturation, and brightness) when you work with color in
applications; others provide useful background information. Color
is a complex topic, so consider this a starting point for
experimentation and further research.

The physics of color

The human eye can see electromagnetic radiation at wavelengths
between 400 nanometers (purplish blue) and 700 nanometers
(red). This range is called the visible spectrum of light. We see
pure spectral light as intensely saturated or pure colors. Sunlight
at midday, which we perceive as white or neutral light, is
composed of light from across the visible spectrum in more or less
equal proportions. Shining sunlight through a prism separates it
into its spectral components, resulting in the familiar rainbow of
colors shown in the following figure.
