VPR can save thousands of dollars in time and materials by eliminating one of the normal two G7 press runs.


The environmental and financial impact of VPR will benefit small and large printers alike. The ROI can be realized on the very first job.

Without VPR, obtaining a press profile from a G7-calibrated press requires at least two press runs; one with null plate curves to calculate the G7 calibration curves, and a second to print the profiling target through the resulting plate curves to profile the press.

VPR can eliminate the need for the second press run. The G7 curves calculated from the first run are applied mathematically to the profiling target measurements of the first run, producing measurements that appear as if they were produced on a second "virtual" run.

"VPR is worth it's weight in gold." said Mike Graff, CEO of Sandy Alexander, Clifton NJ. "The VPR option can pay for itself in a single day."

The savings are greater than you might think. The first press run can be used to print on a number of different paper types. If VPR eliminates the second runs for each paper, one press run might be all that's needed to G7-calibrate a group of papers. That's a huge savings.
