We work with four different printing methods in our corrugated board production.
A flexographic print is made during the manufacturing process of the box. A plate is mounted on the press and the print is applied to the box in a continuous process. The method allows for relatively low printing costs for longer batches. The disadvantage is that a separate plate is needed for each colour printed on the box. The method is particularly suitable for simpler print, such as logos and simpler pictures on the outer packaging.
This is the latest method for printing on corrugated board and can be compared to a normal inkjet printer, although it is significantly larger. We offer a printing width of 2,050 mm, the length is limited by the sheet length. This printing method requires no plates and is instead based on a PDF file. The file must be of high quality; it is ‘ripped’ in the program and is then ready to be sent to the printer. The method is particularly suitable for shorter batch and there is no limit to the number of colours. Photo images can be printed as well. Very suitable for display materials, etc.
Offset printing provides the best quality. The print cannot be applied directly onto the board, but is instead printed on a thinner paper, approx. 100 g, which is then laminated onto the corrugated board. Offset printing is suitable for larger batches and when a very high printing quality is required. The initial costs are relatively high.
This method provides a very high printing quality, but has its limitations in what can be printed: one colour is printed at a time. Photo images cannot be printed. Instead of a plate, a film is used, which is subsequently used for preparing a screen frame. The initial costs are approximately the same as for flexography.
