GMI Implementation & Configuration 2

Question 1

When configuring a spectrophotometer for inline press measurement, which illumination geometry is most commonly specified by GMI standards?

Accepted Answer

d/8° with specular excluded

Answer

GMI standards typically specify d/8° with specular component excluded (SCE) to best correlate with how a human observer views printed materials.

Question 2

During ICC profile implementation for a CMYK press, what is the primary purpose of the perceptual rendering intent?

Accepted Answer

To compress the source gamut proportionally into the destination gamut

Answer

Perceptual rendering intent compresses the entire source gamut proportionally into the destination gamut, preserving color relationships even when colors are out of gamut.

Question 3

A GMI implementation plan calls for verification of total ink coverage (TIC). What is the typical maximum TIC limit for commercial sheetfed offset printing?

Accepted Answer

320%

Answer

Commercial sheetfed offset printing typically caps TIC at 320% to prevent ink trapping problems and slow drying.

Question 4

In configuring a color management workflow, which file format is the correct container for an ICC device link profile?

Accepted Answer

Both .icc and .icm

Answer

ICC device link profiles use either the .icc or .icm file extension — both are valid containers for ICC profile data including device link profiles.

Question 5

When implementing G7 calibration on a digital press, what is the primary target metric for the Neutral Print Density Curve (NPDC)?

Accepted Answer

Setting the Chromatic and Achromatic NPDCs to defined L* values at key tone steps

Answer

G7 calibration targets specific L* values for the NPDC at defined tone steps to achieve consistent gray appearance across different printing systems.
