G7 Proofing & Contract Proofing 2

Question 1

What is the minimum bit depth recommended for a display used in professional G7 soft proofing?

Accepted Answer

10-bit

Answer

A 10-bit display is recommended for soft proofing because it provides smoother gradients and reduces banding in shadow and highlight areas.

Question 2

In soft proofing software, enabling 'Simulate Paper Color' achieves what primary effect?

Accepted Answer

Simulates the white point and optical brightener effect of the target substrate

Answer

Simulate Paper Color uses the ICC profile's media white point to show how the substrate's color, including optical brighteners, will affect final print appearance.

Question 3

Which standard defines the viewing conditions used when evaluating proofs and printed samples in graphic arts?

Accepted Answer

ISO 3664

Answer

ISO 3664 specifies graphic technology viewing conditions, including D50 illumination at 2000 lux for critical comparison of proofs and prints.

Question 4

What is the purpose of measuring an IT8.7/4 target on a proofing device?

Accepted Answer

To characterize the proofer's full color response and build an accurate ICC output profile

Answer

The IT8.7/4 characterization target provides comprehensive patch data needed to build an accurate ICC profile describing the proofing device's color output.

Question 5

A G7-compliant proof must primarily demonstrate correct:

Accepted Answer

Neutral gray balance and Neutral Print Density Curve (NPDC) conformance

Answer

G7's defining requirement is accurate neutral gray balance and NPDC conformance, which ensures predictable tone and color across different printing systems.
