2. Why G7?
2
• You want to visually match one or more printing
devices
• You want truly neutral colors (grays) and correct
tonality from highlight to midtone
– The most common visual reference colors
– Helps to achieve best saturated colors
• You want a competitive advantage for your print
business

3. Agenda
• G7 background & history
• Where Neutral Print Density Curves (NPDC) come from
• Difference between G7 calibration and linearization
• G7 process for conventional
• G7 calibration for Fiery servers
• Resources including how-to guide and simulation

4. G7 background & history

5. What is the G7 process?
• Method of calibrating press or
proofer to common grayscale
appearance
5

6. Shared neutral appearance

7. How is G7 calibration performed?
7
• Print systems may be G7 calibrated by
loading Neutral Print Density Curves
(NPDC) on the platesetter for conventional
presses or on the Digital Front End (DFE)
for digital systems

8. Where do NPDC curves come from?
• NPDC curves can
be calculated
manually using
“fan paper”
8

9. Where do NPDC curves come from?
• NPDC curves may be created with
software tools and loaded on print system
9

10. Where do NPDC curves come from?
• NPDC curves may be created directly on
the DFE for a digital print system
10

11. Loading NPDC curves on a print system
• NPDC curves may be
entered or imported on
the front end for a
platesetter (conventional)
• NPDC curves may be
entered or loaded on some
DFEs (digital)
11

12. What is the difference between G7
calibration and linearization?
12

13. Linearization corrects uneven tonal
response
13

14. Linearization provides even tonal response
14

15. Without Linearization
15

16. With Linearization
16

17. Linearization is done for all colors
17

18. The difference with G7 calibration
• Linearization may be
performed before G7
• The results of G7
calibration are specific
curves for each color that
are not visually linear
18

19. The CtP experience
• In the 1990s North American printers
moved from film-based to CtP
(Computer-to-Plate) workflows
• The quality of printing in the U.S.
suffered badly during this transition

24. 24
What is a P2P target?

25. Introducing the P2P target for G7 calibration
25
• Columns 1-3 : Solids for ISO 12647 and
linearization for CMY

26. Introducing the P2P target for G7 calibration
26
• Columns 1-3 : Solids for ISO 12647 and
linearization for CMY
• Column 4 : K tints for K NPDC

27. Introducing the P2P target for G7 calibration
27
• Columns 1-3 : Solids for ISO 12647 and
linearization for CMY
• Column 4 : K tints for K NPDC
• Column 5 : Gray balanced CMY builds

28. Introducing the P2P target for G7 calibration
28
• Columns 1-3 : Solids for ISO 12647 and
linearization for CMY
• Column 4 : K tints for K NPDC
• Column 5 : Gray balanced CMY builds
• Columns 6 – 12: Gray-finder tints

29. How did G7 solve the CtP problem?
29
• 98% of color separations
have been made in
Photoshop since 1995

30. How did G7 solve the CtP problem?
30
• Many users are not aware they are converting to
“U.S. Web Coated SWOPv2”
– CGATS TR 001 reference

31. How did G7 solve the CtP problem?
31
• Photoshop separations match the tone and
gray balance of CGATS TR 001
– U.S. Web Coated SWOP v.2
• Does G7 calibration give the same match?
Let’s find out…

32. Applying CGATS TR 001 to P2P

35. What about Europe and other regions?
35
• In general, Europe and other regions have
not adopted G7 calibration methodology
• Many regions are still interested in “Near
neutral calibration”

41. G7 process for conventional presses
41

42. G7 for conventional best practices
• Order more paper than you think you need
• Let the press run in for 500-1000
impressions after makeready
• Remember to run press at production
speed
42

43. G7 test form
43

44. Calibration run
• Press run with linear plating curves
• Choose acceptable forms (12647-2 soilds)
• Cut out P2Ps and measure
– Fiery Measure or other software
44

45. Create curves
• Load measurements
into Curve software
• Export curves
• Load on platesetter
45

46. Measure G7 qualification target
• Press run with G7 plating curves loaded
(“qualification run”)
• Measure the P2P target for qualification
• Press fingerprinting (ICC) – optional
– Best practice for digital proofing
46

47. G7 calibration process for digital
47

48. G7 for cut-sheet digital best practices
• Engine calibration from press panel
• Engine warm-up pages
• Averaging multiple P2P targets
