Printing

Our prining process is according following standard and recomendation

German Printing and Media Industries Federation, Berlin (BVDM)

More technical detail you can find in document published in Media Standard Print document. This free to download document describe more information related to ISO standards in Graphic Industry

We don't go deep in detail, we just sumarize some important point in this document.

Printing sequences

We allways print from darkest to lightest color, our printing sequences is KCMY according ISO 12647-2:2013.

Ink thicknes

It's common in conversation that we use word Density to describe ink thicknes on printed sheet. It's wrong but in we ususaly use word higher density do describe higher ink layer thicknes or lowe density to describe lower ink thickness.

Tolerances

This value is for ideal (imaginary ink) which in real life does not exist. Ink manufacturer try hard to achieve this value. In simply language this is median value of all inks in the market.

It's good to know that there is allways tolerances what we can achive.

During the print run, there is also a variation on the printed sheet because of production print fluctuation.
