Read the first 6 GMI Color Management & Quality Standards flashcards as text
Which color model is most commonly used as the standard for print production in the GMI certification framework?
Answer: CMYK
CMYK (Cyan, Magenta, Yellow, Key/Black) is the standard color model for print production because it reflects how inks are mixed on press.
What is an ICC profile used for in graphic production workflows?
Answer: Defining color behavior of a device or color space
ICC profiles define the color characteristics of a device or color space, enabling consistent color reproduction across different devices.
Which instrument is most commonly used to measure color accuracy on printed output in GMI-certified facilities?
Answer: Spectrophotometer
A spectrophotometer measures the full spectral reflectance of a color patch, providing the most accurate color data for quality control.
In GMI color standards, what does Delta E (ΔE) measure?
Answer: Color difference between two samples
Delta E quantifies the perceptual difference between two colors, with lower values indicating closer color matches.
What is the purpose of a gray balance target in GMI print quality verification?
Answer: To verify that CMY overprints produce a neutral gray without color cast
Gray balance targets confirm that the correct CMY dot values produce a visually neutral gray, ensuring overall color accuracy on press.
Which ISO standard is most commonly referenced in GMI color management guidelines for offset lithographic printing?
Answer: ISO 12647-2
ISO 12647-2 specifies process control parameters for offset lithographic printing, including ink colors, dot gain, and paper types.
