Transcription

1 Linearization in Fiery proserver and Fiery XF Wide Format Series Kerry Moloney Product Marketing Manager Fiery Wide Format John Nate Educational Architect and Trainer Fiery Wide Format

2 Session overview Linearizations really are the foundation of great ICC color profiles Great ICC profiles deliver the most accurate color matches regardless off your chosen printers, inks and substrates Creating custom color files for all your printer, ink and substrate combinations is a reality This session guides you through the linearization process and best practices to create the best color output for your customers Take a poll... 2

3 After this webinar, you will be able to understand the importance of color calibration. understand the different types of drivers available. select the best driver available. create custom calibration files specifically for your inks and substrates. 3

4 Your color toolkit What do you have available 4

5 The EFI solution Built-in capability Create Base Linearization 5

6 Fiery XF color options Basic Color Tools options Color Profiler options 6

31 Contone drivers Per-channel linearity 31

32 Contone drivers Per-channel linearity - advanced Normally no adjustment needed 32

54 VUTEk, Matan, & Reggiani linearization The same theory Some visual targets Additional controls 54

55 VUTEk, Matan, & Reggiani linearization 55

56 VUTEk, Matan, & Reggiani linearization Use caution when modifying values. Do not use them to try to reduce ink consumption. 56

57 VUTEk, Matan, & Reggiani linearization Pre-ink limits are only useful if your printer/media combination cannot handle the full amount of inks, and bleeding, mottling, or drastic ink thickness effects can be seen on your primary color gradations. 57

58 VUTEk, Matan, & Reggiani linearization Unlock icon, used to modify ink limits individually 58

59 VUTEk & Matan linearization Advanced limits (medium light inks) 59

60 VUTEk & Matan linearization Advanced limits (medium light inks) Select a value where you can just detect that the hexagon is visible. 60

61 VUTEk & Matan linearization Advanced limits (medium light inks) 61

62 Reggiani linearization New Advanced Ink Limit charts 62

63 Reggiani linearization New Advanced Ink Limit charts Select a value where the small extensions are not filling in 63

64 VUTEk, Matan, & Reggiani Linearization 64

65 VUTEk, Matan, & Reggiani recommendations Never touch the 200% or the 300% values Step back and lower your primary ink limits If you must 200% - Never lower than 190% 300% - Never lower than 285% Only adjust the 400% NEVER go below 360% Step back and lower your primary ink limits 65

66 5% to 15% ink reduction = large gamut impact! L*= L*= L*= b* 20 b* 20 b* a* a* a* 66

67 No ink limits 67

68 15% ink reduction 68

69 L * Ink reduction comparison [% ] 69

71 VUTEk, Matan, & Reggiani linearization 71

72 White ink linearization Two methods Method #1 DON T! Fiery will generate a curve based upon the other color curves Method #2 custom built 72

73 White ink linearization No Normal ink adjustment If needed, use Pre-ink Limits 73

74 White ink linearization Recommendation: Leave Dot gain at 50% setting at 0% 74

75 Session summary We learned Why custom linearizations are worth it Superior color matches, better gray balances, potential ink savings Different printer driver types, and where they are best used Do s and don ts of ink limiting and ink reduction 75
