High quality direct offset printing of corrugated cardboard

Miniature corrugated cardboard (F-type and G-type) High-quality direct offset mainly depends on the following factors:

1. The printer must be able to print miniature corrugated cardboard from the structure;

2. The blanket has a good elasticity, can compensate for the peak of the corrugated board, and the pressure difference in the valley can help to improve the printing effect;

3. Plates made for sales packaging can also be used for printing transport packages. If for other reasons there must be special plate making for the sales package, then due to taking into account some principles of plate making, it will help to improve the quality of direct offset printing of corrugated cardboard.

4. Substrate also has an important influence on the printing effect. The direct color printing on the tan base layer does not achieve excellent color effect, and when the liner board is used as the printing material, due to the different types of coating, not only the glossiness and abrasion resistance of the printing ink layer are affected, but also The "cocooning board" effect also has a great influence.

5. Ink performance also has a great influence on print quality. The Well-Perfect-EV1010-W type ink developed by German GS (Gebr. Schmidl) ink factory is specially developed for the direct offset printing of micro-corrugated cardboard (F-type and G-type). Its main characteristics are high ink gloss and resistance. High abrasion resistance, medium absorption speed, good printability, and the ability to further avoid printing "squeaking" effect. For the printing of corrugated boxes, since the cartons are subjected to a large mechanical load during storage and transportation, it is preferable to perform protective glazing after printing.
