Features of offset printing on single-layer cardboard

Thin single-layer cardboard is mainly used to manufacture individual packaging in which goods are placed. Suitable for products with a lightweight of up to 1 kg, and the image can be applied to it using special offset printing machines (Speedmaster Heidelberg, Komori, Manroland, KBA Rapida)

Minimum circulation

Offset printing on single-layer cardboard is carried out in large batches of 3000-5000 pieces. This is because setting up an offset printing machine requires at least 50 sheets per color. If the print is 4-color, the ready time for rolling out a color will be 200 sheets. In addition to adjustment sheets for printing, other operations also require additional sheets to set up equipment for the print run. Therefore, printing on offset machines is not profitable for customers with small runs. 

Offset printing on thin cardboard is advantageous because it:

  • It allows you to realize any design ideas and will enable you to obtain images of high and stable quality.
  • Cost-effective when producing large batches of over 3000-5000 pieces.
