GMI Implementation & Configuration 3

Question 1

When building a custom press ICC profile for GMI certification, what is the minimum recommended number of color patches in the measurement target?

Accepted Answer

288

Answer

A minimum of 288 patches (such as the IT8.7/4 target) is generally recommended to build a robust press ICC profile for certification purposes.

Question 2

A technician is configuring dot gain compensation curves in a RIP. Which curve adjustment would INCREASE the physical dot size on press?

Accepted Answer

Lowering the midtone value in the compensation curve

Answer

Lowering the midtone compensation value sends less ink signal, meaning the RIP compensates less, which results in more physical dot gain and larger dots on press.

Question 3

In a GMI-compliant facility, which document formally defines the acceptable process parameters and measurement tolerances for each substrate and press combination?

Accepted Answer

Process control plan

Answer

The process control plan is the governing document that specifies acceptable parameters, measurement tolerances, and corrective action triggers for each press-substrate combination.

Question 4

When configuring measurement intervals for a SPC (Statistical Process Control) system on press, what does a control chart's UCL represent?

Accepted Answer

The upper boundary beyond which the process is considered out of control

Answer

The Upper Control Limit (UCL) is the statistical boundary above which a process is considered out of statistical control and corrective action should be taken.

Question 5

Which configuration setting in a color server directly controls how out-of-gamut spot colors are mapped when converting to process inks?

Accepted Answer

Rendering intent for spot color conversion

Answer

The rendering intent applied to spot color conversions determines how out-of-gamut spot colors are handled when converting to CMYK process inks.
