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 print characteristics. That means that we are measuring changes as a result of a mechanical change on press. For example, a change in ink density can be a direct result of the change of ink film thickness or volume that is applied. A change in dot gain can be a result of a change in impression pressure or the blanket and packing condition. Ink trap is a measure of how well an ink transfers to a substrate with a previous ink applied.
My concern is , most printing companies in Nigeria are not vast in the technology and science of printing.
The operators and the owners of the company rely heavily on complaints from customers. And this is not helpful to the growth of printing in Nigeria.
The machine operators and even some production managers lack knowledge in printing technology and don't what required of them to print well. Some executives are not ready to improve on quality measurements at all or invest in the right equipment to optimise their processes.
This topic on densitometer is well treated .
