Printers and brand owners no longer have to use control strips for quality benchmarking thanks to a new image-based service from the Flemish Innovation Center for Graphic Communication (VIGC), which enables users to make objective comparisons of different versions of printed packaging.
The VIGC Quality Perception Benchmark is based on seven parameters relevant to visual perception of quality. Measurements are based on images in the print job, making control strips unnecessary.
Fons Put, senior consultant at VIGC, explains: "We had to perform a quality benchmark on finished print jobs, so we couldn't start with the traditional measurements - density or the colours of CMYK solids in CIELab. We needed to go for other parameters that are important for image perception, such as dynamic range."
"So we devised a new measuring methodology to get an objective assessment of these visual parameters. Differences in these parameters between multiple samples can always be related to one or more printing parameters, such as density or print contrast."
A crucial factor in the VIGC Quality Perception Benchmark is that all tested parameters relate to printing parameters. In its assessment report, the VIGC does not only show whether samples conform or differ, but also it states what could cause the differences, and which printing parameters are probably different.
