4 Colour Basics 101

5 RGB Colour Device Dependent

6 Why Can t I Print with RGB? The problem with RGB colour model is that for print, the colours must be opaque Blue Red Paper

7 CMY(K) Colour Device Dependent

8 Printing Colours with CMYK CMY are transparent colourants that act as filters, selectively blocking RGB, respectively Cyan Magenta Paper

9 Device Dependent Issues

10 CIE L*a*b* Device Independent

11 Measuring Device Independent Colour Spectrophotometer

12 Definition of Colour Gamut The total reproducible range of colours on a device Almost right! The total reproducible range of colours on a device expressed in device independent colour space

13 Definition of Colour 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 colour space for a given device OutputProfile.icc

25 Calibration

26 Calibration Maintains consistent tone reproduction Provides consistency from day to day Compensates for environmental fluctuations Keeps colour in a known and repeatable state

27 What Does Calibration Do?

28 Calibration Summary Establishes even gradation across the tonal scale Examples 75% patch: lose detail in shadows 7-10% patch: lose details in highlights

29 Calibration Example Before After

30 What Else Affects Calibration? Media type Press technology and speed Print settings Environmental variables

31 When To Calibrate? After the engine is warmed up Before a large job Media changes

32 Spectrophotometers EFI ES-6000 Network-connected scanning spectrophotometer Eliminates manual scanning of color targets Can be shared by multiple network users EFI ES-2000 Handheld spectrophotometer Accurate spot color measurements

33 Calibration Demo

34 Un-Calibrated Calibrated Where Are We Now? Consistent, but not Accurate Colour Neither consistent nor Accurate Colour

35 Profiling

36 Colour Profiles (Output) Defines gamut of print system DFEs include factory default profiles Best practice: create custom profiles

37 Output Profile Creation Need two sets of values 1. Device values (CMYK) 2. Device independent values (L*a*b*) from spectrophotometer

38 Output Profile Creation Use profiling software to create ICC output profile from measurements

39 Profiling Demo

40 Selecting the Output Profile Select Output Profile
