G7 Proofing & Contract Proofing 3

Question 1

In G7 proofing, the P2P (Print to Paper) target is primarily used to:

Accepted Answer

Measure tone response (NPDC) across the CMY gray scale for G7 verification

Answer

Compare a proof and press sheet side-by-side visually

Answer

Profile inkjet paper substrates for wide-format printing

Answer

Evaluate press-to-press color consistency across shifts

Question 2

How does G7 define 'near-neutral' gray balance on a proof or press sheet?

Accepted Answer

Colorimetrically neutral appearance verified by spectrophotometer in CIELAB

Answer

Equal RGB display values on a calibrated monitor

Answer

Equal CMY percentage dot values at each tonal step

Answer

Equal ink density readings for cyan, magenta, and yellow solids

Question 3

If a G7 contract proof fails colorimetric verification, what is the recommended first corrective action?

Accepted Answer

Investigate and adjust the proofer's linearization and rebuild or refine its ICC profile

Answer

Replace the proof printer with a newer model

Answer

Switch to a different substrate immediately

Answer

Increase all ink limits by 10% to boost saturation

Question 4

The Neutral Print Density Curve (NPDC) in G7 is constructed from measurements of:

Accepted Answer

A tonal scale of CMY gray overprint patches spanning highlight to shadow

Answer

Solid CMYK patches only at 100% coverage

Answer

Single-channel cyan, magenta, and yellow gradients measured independently

Answer

Black channel tonal patches printed at varying densities

Question 5

What does 'proof-to-press correlation' measure in a G7 quality control workflow?

Accepted Answer

How closely production press output matches the colorimetric values of the approved contract proof

Answer

The time elapsed between proofing and going to press

Answer

The spectral properties of the printing inks used on press

Answer

The halftone dot gain measured on the press sheet

Question 6

In a G7 workflow, who has the authority to approve the contract proof before production printing begins?

Accepted Answer

The client or their authorized representative

Answer

The press operator, based on density measurements

Answer

The ICC profile creator or color manager

Answer

The instrument manufacturer's certified calibration technician

Question 7

Which capability in color management software allows a G7 practitioner to compare proof measurements against GRACoL or SWOP reference characterization data?

Accepted Answer

ΔE reporting and spectral comparison against loaded reference characterization data sets

Answer

Ink limit optimization tool for total area coverage

Answer

PDF/X-4 preflight module for file compliance

Answer

Dot gain compensation calculator for press curves
