Color management
Since the color on a screen differs from the color produced by the 
press, it is necessary to have a Color Management System 
(CMS). The CMS identifies and bridges the gap between the RGB 
and CMYK color spaces belonging to your monitor, press, and 
scanner. Mac and Mac OS compatible computers use the Apple 
ColorSync CMS to implement and handle the profiles of these 
devices. For Windows - based PCs, refer to your PC Operator 
Manual for the compatible CMS.
Without a color management system, one image will appear 
different when reproduced on different devices due to 
inconsistencies in color gamuts.
A color management system helps you obtain more consistent 
results by aligning the color gamuts used by different devices.
Halftone dots and screen angles
Halftone screens
To produce continuous tone images on an output device, bitmaps 
and process color graphics must be broken into a series of dots of 
various sizes and colors. This creates a halftone screen. Halftone 
screens combine cyan, magenta, yellow, and black dots at 
different screen angles to form a four-color image. The structure 
and patterns by which the colors are combined are the halftone 
screens. When a certain color is required, the halftone screen 
determines the dots to color, the color to use, and the degree to 
which each dot is colored. The figure on the left illustrates a 
halftone screen.
