Calibrated Underpacking Sheets

Quality products, assorted by colour

For an optimum printing result in the offset printing process, among others, the absolutely even pressure of the printing cylinders against the entire area is the decisive factor. This can be ensured by underpacking sheets having different thicknesses. The underpacking sheets are manufactured in accordance with ISO Standards for calibrated materials and are available from 0.075 to 0.5 mm. A special colour scheme facilitates the choice of the correct sheet.

A special anti-slip surface reduces slipping and prevents the sheet from being pushed together under the printing plate or rubber blanket. A thorough impregnation of the underpacking sheet offers protection against swelling.

  • Add appr. 5/100 for compressible blankets.
