Why Is It Important to Understand and Manage Color?
• Customer retention
– Educate the customer
– Understand limitations
• Save time
• Save money
3
Why Can’t I Print with RGB?
• The problem with RGB color model is that for print, the colors must be opaque
Paper Red
Blue
6
Printing Colors with CMYK
• CMY are transparent colorants that act as filters, selectively blocking RGB, respectively
Paper Magenta
Cyan

Definition of Color Gamut
• The total reproducible range of colors on a device – Almost right!
• The total reproducible range of colors on a device expressed in device independent color space
12
Definition of Color Management
• Gamut mapping with the intent of preserving object appearance
• What is an ICC profile? – A look up table (LUT) that defines the
mapping of device dependent to device independent color space for a given device

Calibration
• Maintains consistent tone reproduction
• Provides consistency from day to day
• Compensates for environmental fluctuations
• Keeps color in a known and repeatable state
26
Calibration Summary
• Establishes even gradation across the tonal scale
• Examples
– 75% patch: lose detail in shadows
– 7-10% patch: lose details in highlights
28
What Else Affects Calibration?
• Media changes
• Press technology and speed
• Print settings
• Environmental variables

Color Profiles (Output)
• Defines gamut of print system
• DFEs include factory default profiles
• Best practice: create custom profiles
Factory Default ICC Custom ICC
My engine, paper, environment!
35
Output Profile Creation
• Need two sets of values 1. Device values (CMYK)
2. Device independent values (L*a*b*) from spectrophotometer
36 Output profiling patches on
calibrated print system
Output Profile Creation
• Use profiling software to create ICC output profile from measurements
