Multi-Layer Printing Modes, Hp Inc

Defensive Publications Series

One of the applications of printers with white inks is to print on a transparent substrate and cover it

with white, so that the image, printed in mirror image, is seen through the substrate on a white

background. An unmirrored image can be printed on the other side, allowing for an image on both sides

of the substrate. This is referred to as a (three‐layer) sandwich mode.

To reduce translucency, a variation is the five‐layer sandwich mode, in which the middle white layer is

replaced by another sandwich of white, black and white.

Depending on the hardware, in …

Algorithm To Compensate Skew For Rigid Medias, Hp Inc

Defensive Publications Series

The world of printing on rigid materials often demands skew requirements that are difficult to achieve in

non-true flat belt printers. This requirement has its origin in the need of customers to optimize printing

processes, saving post-processing and media waste.

Often, clients must print full bleed or leave blank margins if they want to have an image printed on all

support. Both strategies can be avoided if the printer has a good skew compensation strategy with the

consequent savings for the client.

Total skew on images printed on rigid medias is the sum of three contributors: media orthogonality, media

load …
