Preprint means that the paper top layer of (corrugated)cardboard is printed first, before it is made (corrugated) cardboard. We call direct printing on corrugated cardboard Postprint. You can usually recognize postprint by the light/dark stripe formation, parallel to the wave of the cardboard. This is also called the “washboard effect”.
Felco has been the leading Preprint Flexo printer in Europe since 1987. During the printing of Preprint, we fully concentrate on the quality of the printed image. The production of (corrugated) cardboard and the die-cutting of the box will take place at a later stage. We print effortlessly on the paper top layer of (corrugated) cardboard in 54 or 60 l / cm grid in 8 colors at a width of 2.5 meters. The register of the colors and the image quality is comparable to offset.
