![]() Ink trap is a measure of how well an ink transfers to a substrate with a previous ink applied. A change in dot gain can be a result of a change in impression pressure or the blanket and packing condition. For example, a change in ink density can be a direct result of the change of ink film thickness or volume that is applied. That means that we are measuring changes as a result of a mechanical change on press. ![]() ![]() These are known as mechanical print characteristics. This can include measurements of solid ink density, tone value increase (also known as dot gain), Ink Trap, and other print characteristics. Using a densitometer can provide quantitative actionable feedback for the press operator. 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. There are different levels of process control that are used for print. ![]() Out of Production Products - Find Your Upgrade. ![]()
