G7 G7 Print Production & Substrate Management 2 — Questions and Answers
Question 1: In G7 press calibration, what does the term 'HR' stand for in the context of the gray balance aim point?
- High Resolution
- Highlight Rendering (Correct answer)
- Hue Rotation
- Highlight Response
Correct answer: Highlight Rendering
HR (Highlight Response) refers to how the press renders light tones, which is a key parameter evaluated during G7 gray balance calibration.
Question 2: Which G7 compliance level requires only that gray balance and tonality targets are met without matching a specific reference?
- G7 Targeted
- G7 Colorspace
- G7 Grayscale (Correct answer)
- G7 Master
Correct answer: G7 Grayscale
G7 Grayscale is the foundational compliance level requiring only that the press achieves correct gray balance and NPDC curve shape.
Question 3: What does NPDC stand for in G7 calibration?
- Neutral Print Density Curve (Correct answer)
- Normalized Print Density Calibration
- Neutral Print Dot Curve
- Normalized Press Density Curve
Correct answer: Neutral Print Density Curve
NPDC (Neutral Print Density Curve) defines the relationship between CMY halftone values and neutral density in G7-calibrated output.
Question 4: When performing G7 calibration on a digital press, plate curves are replaced by what?
- Tone reproduction curves (TRCs) in the RIP (Correct answer)
- Ink density adjustments
- Physical press form adjustments
- Screen ruling modifications
Correct answer: Tone reproduction curves (TRCs) in the RIP
On digital presses, tone reproduction curves (TRCs) within the RIP software serve the equivalent function of plate curves on offset presses for G7 calibration.
Question 5: What is the minimum number of measurement patches typically required in a P2P25 target for full G7 analysis?
- 25
- 50 (Correct answer)
- 75
- 125
Correct answer: 50
The P2P25 target contains 25 gray patches plus 25 CMY combination patches, totaling 50 key patches for G7 gray balance analysis.
Question 6: Which ink color sequence is standard for wet-on-wet offset lithographic printing in G7 workflows?
- Cyan, Magenta, Yellow, Black
- Black, Cyan, Magenta, Yellow (Correct answer)
- Yellow, Magenta, Cyan, Black
- Magenta, Cyan, Yellow, Black
Correct answer: Black, Cyan, Magenta, Yellow
The standard ink-down sequence for wet-on-wet offset printing is Black, Cyan, Magenta, Yellow (KCMY), though G7 calibration accounts for trapping differences.
