All Printing Resources introduces G7 qualification for flexo

March 3, 2009

Certification signifies that a converter has been trained to print to the new G7 Proof-to-Print Process.

All Printing Resources (APR), Glendale Heights, IL, USA, a supplier of flexographic equipment and services, has established a G7 Master Printer certification program for flexographic operations. Developed by IDEAlliance and the GRACoL committee, G7 Master qualification signifies that a converter has been trained to print to the new G7 Proof-to-Print Process and has calibrated the proofing system or press to the G7 method. The qualification also indicates that a converter uses the most modern technology, techniques and process controls and standards required to produce high-quality printing.

“This is a process that’s traditionally been associated with offset printing presses and is now becoming more of a factor in the flexo market as we continually strive to improve color consistency,” says Dave Nieman, president of All Printing Resources.

G7 helps printers print consistent color, with less preparation and less waste, and reliably produce high quality printing that matches from proof to press and from press to press, says Richard Black, APR’s director of digital solutions. “The G7 process provides predictable and consistent color without requiring printers to set up presses on a job-by-job basis,” he says.

The G7 proof-to-print process is based on the principles of digital imaging, spectrophotometry and computer-to-plate technologies and is a simple calibration process that allows converters to achieve a visual match between their proofing and printing methods. It is named for its gray scale calibration technique and the seven ISO ink colors it requires. The “G” refers to the calibrating gray values, while the “7” refers to the seven primary color values: cyan, magenta, yellow, black, red, green and blue defined by the ISO.

APR’s G7 Qualification program for flexographic printers includes on-site consulting and a complete program to calibrate, linearize and profile the press. More information is available at
