Офсетний друк — що це? Технологія та особливості

Offset printing is the most common printing method in the printing industry. It ensures high image quality, accurate color reproduction, and cost-effectiveness for large print runs. It is used to produce magazines, catalogs, labels, packaging, and promotional materials. In this article, we explain what offset printing is, how it works, and what advantages it offers.

The principle of offset printing technology

Offset printing is an indirect method of printing. The image is first transferred from the printing plate (cliché) to a rubber blanket cylinder, and then from there onto the surface of paper or another material. This process reduces wear on the plates and allows for extremely detailed reproduction.

How does offset printing work?

  1. A digital layout is created and a printing plate (cliché) is made for each color (CMYK);
  2. Ink is applied to the plate but does not adhere to non-image areas due to a hydrophobic coating;
  3. The ink is transferred to a rubber roller;
  4. Then from the roller onto the paper or other material;
  5. After printing, the material is dried, trimmed, and, if necessary, additionally finished (e.g. lamination, varnishing).

Main advantages of offset printing

  • High print quality – sharp images, accurate color matching, fine details;
  • Speed and consistency – ideal for large-volume orders;
  • Cost-efficiency – the larger the print run, the lower the unit cost;
  • Compatible with various materials – paper, cardboard, self-adhesive labels, thin plastic;
  • Suitable for post-press processing – creasing, die-cutting, embossing, varnishing, etc.
