What is dot gain in the context of GMI print quality standards?
Answer: The increase in dot size from film to press output
Dot gain refers to the increase in halftone dot size that occurs when ink spreads on the substrate, affecting tone reproduction.
In GMI quality audits, what is the role of a press fingerprint?
Answer: To establish baseline color and tone reproduction characteristics of a specific press
A press fingerprint documents the unique color and tonal behavior of a specific press, enabling accurate profiles and consistent output.
Which color space is device-independent and used as the connection space in ICC color management?
Answer: CIELAB
CIELAB (L*a*b*) is a device-independent color space used as the Profile Connection Space (PCS) in ICC color management workflows.
What does soft proofing allow a prepress operator to do in a GMI-compliant workflow?
Answer: Simulate the appearance of press output on a calibrated display
Soft proofing uses a calibrated display and ICC profiles to simulate how the final printed piece will look, reducing the need for physical proofs.
In GMI certification, what is the maximum acceptable ΔE tolerance for a contract proof compared to press output under G7 methodology?
Answer: ΔE ≤ 2.0
G7 methodology typically requires a ΔE of 2.0 or less between a contract proof and press output for acceptable color conformance.
What is the primary purpose of Total Ink Coverage (TIC) limits in GMI print production?
Answer: To prevent ink trapping issues and paper saturation on press
TIC limits prevent excessive ink laydown that can cause drying problems, ink trapping failures, and paper damage on press.
