There are different levels of process control that are used for print. While visual comparisons can be used to provide a rudimentary judgment of a match, they can be very subjective, and thus not very accurate, or repeatable.    Using a densitometer can provide quantitative actionable feedback for the press operator. This can include measurements of solid ink density, tone value increase (also known as dot gain), Ink Trap, and other print characteristics. These are known as mechanical ...

G7® is a proof-to-print process control method that allows you to reliably and efficiently match the visual appearance of the output from multiple printing devices.

With BestMatch, you can confirm t...
