How to remove calcium glaze from printing press rollers

Calcium deposits can disrupt ink transfer and ink–water balance. A standard ink wash removes organic residues but may not dissolve a mineral glaze.

Calcium glaze on a printing roller and surface inspection — Mineral deposits need a different procedure from ordinary ink residues.

Confirm the deposit

A dull glassy film and uneven ink acceptance may indicate calcium glaze, although paper residue, damaged rubber and incorrect pressure can look similar.

Find the source

Calcium may come from paper, water, ink and additives. Review water hardness, fountain-solution conductivity and production history.

Use a two-stage process

First remove ink with the correct wash, then use a mineral-deposit remover as directed. Never mix cleaners or exceed contact time.

Remove chemical residue

Rinse or neutralise as instructed to protect rubber, metal and the next ink charge.

Prevent recurrence

Monitor rollers, water and fountain solution. Set cleaning frequency from condition and manufacturer guidance rather than an arbitrary calendar.
