LETTERPRESS PRINTING

A printing technique when ink is applied to a substrate from a printing plate with printing elements raised above spacing elements. During printing spacing elements do not touch the print-receiving material. The process is carried out under high pressure (at least 15 kg/cm

A printing technique when ink is applied to a substrate from a printing plate with printing elements raised above spacing elements. During printing spacing elements do not touch the print-receiving material. The process is carried out under high pressure (at least 15 kg/cm2) with the use of fast-drying inks.

Special features of the print:

  1. uneven ink distribution in strokes: less ink in the middle than along the edges;

  2. a rim formed by the ink along the edges of a stroke;

  3. deformation of the print-receiving material: protuberance on the back side of a sheet and indentation on the front side of a sheet in the area where the print is applied.

Letterpress printing is often used for printing serial numbers, barcodes, and design elements of covers.
