G7 Print Production & Substrate Management Flashcards

What substrate property most directly affects how ink absorbs and affects the final G7-calibrated color output?

Answer: Surface absorbency and coating type

Surface absorbency and coating type determine ink holdout, which directly impacts dot gain and color density in G7-calibrated output.

In G7 methodology, what term describes the increase in dot size from file value to printed output?

Answer: Tonal value increase (TVI)

Tonal value increase (TVI), also called dot gain, measures the percentage difference between the intended halftone dot size and the actual printed dot size.

Which G7 calibration target is used to evaluate gray balance and achieve neutral print characterization?

Answer: P2P25 target

The P2P25 (Process to Press) target contains CMY patches specifically designed to evaluate gray balance for G7 calibration.

When printing on an uncoated substrate for G7 compliance, which characterization dataset is typically the reference?

Answer: SWOP 2013 C5 (Uncoated)

SWOP 2013 C5 is the industry reference characterization data for uncoated substrates in North American G7 workflows.

What is the primary purpose of a G7 Targeted press run as opposed to a G7 Grayscale calibration?

Answer: To match a specific reference printing condition's full color appearance

G7 Targeted calibration aligns press output to the full color appearance of a specific characterization dataset, not just neutral gray balance.

Which measurement geometry is recommended by G7 specifications for measuring solid ink densities on press?

Answer: 45°/0° geometry

G7 and most printing standards recommend 45°/0° measurement geometry for reflectance measurements of printed substrates.
