In a GMI-certified workflow, which metric is used to evaluate the overall color accuracy of a proof against a printed sheet?
Answer: Mean deltaE 2000 (ΔE00)
Mean deltaE 2000 (ΔE00) is the preferred metric for evaluating overall color accuracy between a proof and a printed sheet in GMI-certified workflows.
A facility is implementing GMI color management and needs to configure its CTP (Computer-to-Plate) system. What is the primary goal of CTP calibration in this context?
Answer: Ensuring linear dot reproduction from file to plate
CTP calibration ensures that the dot sizes written to the plate linearly correspond to the digital file values, establishing a predictable foundation for press calibration.
When configuring a densitometer for GMI process control measurements, what does 'Status T' filter response primarily represent?
Answer: North American standard using narrow-band spectral filters optimized for process inks
Status T is the North American densitometric standard that uses narrow-band filters optimized for measuring CMYK process inks on coated paper.
During implementation of a GMI-compliant press, the technician measures a solid Cyan density of 1.55 when the target is 1.45. What is the appropriate first corrective action?
Answer: Reduce the cyan ink feed/key settings to lower ink film thickness
When solid ink density is too high, the first corrective action is to reduce ink feed on the press to lower the ink film thickness and bring density to target.
Which configuration parameter in a GMI workflow defines the relationship between CTP output dot percentage and the actual ink density on the printed sheet?
Answer: Tone Value Increase (TVI) curve
The Tone Value Increase (TVI) curve, also called dot gain curve, maps the CTP dot percentage to the actual printed dot area, quantifying the mechanical and optical dot gain.
When configuring multi-press color matching under GMI, what is the recommended approach for achieving consistent output across two presses with different gamuts?
Answer: Use a common characterization data standard (e.g., GRACoL) as the aim point for both presses
Targeting a common characterization standard (such as GRACoL or FOGRA) as the aim point for both presses ensures that output is matched to the same color target even if press gamuts differ.
In GMI implementation, what is the purpose of running a 'verification target' after completing press calibration?
Answer: To confirm that the calibrated press meets the defined tolerance criteria before production
A verification target is measured after calibration to objectively confirm that the press output falls within the defined tolerance criteria before production printing begins.
