- the printing impression can be calculated in advance in order to optimally adjust the printed image on the finished product to the target image.
- the substrate may affect the expected color impression of the image, since the substrate itself can have a certain absorption spectrum.
- the color image impression of the color image on the printing substrate can be detected first.
- the substrate impression can be taken into account.
- the substrate is often bonded to the substrate by means of an adhesive.
- the printing impression can be affected since the carrier material and the adhesive can each have a specific absorption spectrum.

So when it is detected how the impression of a selected color of the substrate to the substrate, with the Carrier material is changed, it can also be predicted how the colorimetric impression on the pure substrate differ from the impression printed on the finished packaging. Then, the selected color or the color image can be corrected on the substrate such that the expected print image optimally corresponds to the target image.
- the color image impression of the color image can be measured on a transparent film as substrate.
