Read the first 7 Proofing & Contract Proofing flashcards as text

  1. What is the primary purpose of a contract proof in the G7 workflow?

    Answer: To serve as a binding color reference for production approval

    A contract proof is the agreed-upon color standard that production printing must match before the job is approved for press.

  2. Which international standard defines tolerances for proofing processes working directly from digital data?

    Answer: ISO 12647-7

    ISO 12647-7 specifically covers proofing processes working directly from digital data and defines the tolerances for contract digital color proofing.

  3. In G7 soft proofing, what is the most critical requirement for accurate color simulation on a display?

    Answer: A calibrated, profiled display with the correct ICC rendering intent applied

    Accurate soft proofing requires a calibrated display with a current ICC profile and the appropriate rendering intent to simulate press output correctly.

  4. Which color difference formula is preferred when evaluating G7 proof accuracy against a reference?

    Answer: ΔE00 (CIEDE2000)

    ΔE00 (CIEDE2000) is preferred because it is perceptually uniform and correlates better with human visual assessment than earlier formulas.

  5. What type of measurement device is required to verify the colorimetric accuracy of a contract proof?

    Answer: Spectrophotometer

    A spectrophotometer measures full spectral data needed to calculate accurate CIELAB values for G7 compliance verification.

  6. Which rendering intent is most commonly used when soft proofing a CMYK press profile on a wide-gamut display?

    Answer: Relative Colorimetric with black point compensation

    Relative Colorimetric with black point compensation maps source colors to the output gamut while preserving neutral gray relationships and shadow detail.

  7. A G7 verification print is produced primarily to confirm that:

    Answer: The proofing device meets G7 gray balance and tone response tolerances

    A G7 verification print is a test print used to confirm that a proofing or printing device meets the G7 NPDC and gray balance standards.
