G7 SYSTEM CERTIFICATION REQUIREMENTS

A Certified G7 System has been 3rd party tested and been proven to successfully meet the following requirements:

  • The system calculates CMYK calibration curves (RIP calibration percentages) that produce CMY and K-only NPDC curves that fit the nearest FanGraph curve or average of two curves.
  • The corrected NPDC curve(s) match whatever FanGraph curve(s) fit the dynamic range of the test sample.
  • The system is able to calculate individual CMY calibration curves that together produce a neutral grey balance defined by the G7 specification.
