Rollers for printing

Print quality depends on rollers that hold an even nip across the full width. Hardness variation, run-out or a porous surface all show up as uneven density, streaks or registration problems.

We supply rotogravure printing rollers, stereo rollers and PU and EPDM rollers, new or re-covered on your cores. The compound is matched to your ink system: nitrile for solvent and oil-based inks, EPDM for water-based and UV.

Typical rollers we supply

  • Rotogravure impression rollers
  • Stereo (plate) rollers
  • Ink and coating rollers
  • Anti-static rollers

What matters

What printing buyers need from a rubber supplier

  • Uniform hardness

    Even Shore A hardness along the face for consistent print density.

  • No run-out

    Rollers ground true to the bearing seats for stable impression and registration.

  • Ink and solvent resistance

    Covers that do not swell in your inks and cleaning agents.

How we work

From your old roller or drawing to a roller that runs true

  1. 01

    Roller review

    We check your drawing or old roller, confirm diameter, face length, journals and the hardness you need.

  2. 02

    Cover selection

    A cover compound is proposed for the inks, chemicals and temperatures your roller sees in service.

  3. 03

    Core and covering

    The core is prepared or made new, then the cover is applied without porosity and cured.

  4. 04

    Grinding and inspection

    Ground true to the bearing seats, finished as specified, and checked for hardness and run-out before dispatch.

FAQ

Common questions

Which rubber is best for printing rollers?

Nitrile for oil and solvent-based inks, EPDM for water-based and UV inks. The ink and cleaning chemistry decide the best choice. See the roller selection guide.

Can you match the hardness of my existing roller?

Yes. Send the specified hardness or the roller itself, and we will match it or suggest an adjustment if the current cover wears or swells too quickly.

Need a new roller or a re-cover?

Share your roller drawing or sample, required hardness and what it contacts. Our team will recommend a cover and respond with a quotation.
