Wear Resistance Printing Rubber Rollers Anilox Rollers Customizable

Printing Rubber Rollers
Printing rubber rollers are core transmission components of printing presses, mainly including ink rollers, dampening rollers, ink distributing rollers, form rollers, coating rollers, etc. Made of high-quality elastic materials such as rubber, EPDM, nitrile rubber and silicone, they are processed through precision rubber covering, vulcanization and fine grinding. Used for uniform water transfer, ink transfer, coating and glazing, they ensure stable ink transfer, clear dots and consistent colors. Widely applied to offset printing, flexo printing, gravure printing, coating and laminating equipment, they feature ink resistance, solvent resistance, high temperature resistance, high elasticity, wear resistance and anti-aging properties, being key consumables to ensure printing quality.

Anilox Rollers
Anilox rollers are precision metering and ink transfer components for flexo printing, gravure printing and coating equipment. The roller surface is laser-engraved to form fine cells, which are used to accurately control ink volume and achieve uniform inking. Divided into metal anilox rollers and ceramic anilox rollers, ceramic anilox rollers have high hardness, wear resistance, corrosion resistance and long service life. Widely used in flexographic printing, adhesive label printing, carton pre-printing, coating and glazing, they enable high-screen and high-definition printing, ensuring uniform colors, full solid areas and precise dot reproduction.

Core Product Features

1.Core Features of Printing Rubber Rollers
• Uniform and Stable Ink & Water Transfer: Moderate elasticity and high surface finish ensure uniform distribution of ink and water, eliminating ink bars and water marks.
• Strong Resistance to Ink, Solvents and Chemicals: Compatible with ordinary ink, UV ink, water-based ink and solvent-based ink, not easy to swell or crack.
• Good High Elasticity and Resilience: No deformation under pressure, no eccentricity or vibration during long-term use, ensuring uniform pressure.
• Wear Resistance, Anti-Aging and Long Service Life: High-quality rubber materials combined with high-temperature vulcanization, wear-resistant and not easy to crack, reducing replacement frequency.
• High-Precision Processing: Strict control of coaxiality, circular runout and surface roughness, suitable for high-speed printing presses.
• Customizable and Refurbishable: Supports customization of different diameters, lengths, hardness and rubber types; old rollers can be re-covered to reduce costs.

2.Core Features of Anilox Rollers
• Precision Ink Volume Control: Precise cell depth and opening ratio, high ink transfer rate and uniform ink layer.
• High-Precision Laser Engraving: Clear texture and consistent cells, supporting high-screen printing and restoring fine patterns and text.
• Excellent Ceramic Coating Performance: High hardness, wear resistance, corrosion resistance and anti-ink adhesion, suitable for high-speed and long-term production.
• Wide Application Range: Applicable to various media such as water-based ink, solvent ink, UV ink, varnish and glue.
• Easy to Clean, Not Easy to Clog: Dense and smooth surface, easy to clean, reducing problems such as clogging and poor inking.
• Compatible with High-Speed Printing: Stable rotation and fast inking, meeting the use requirements of high-speed flexo printing presses and coating machines.

How to choose:

1.How to Choose Printing Rubber Rollers
• Select According to Printing Press Model: Choose dampening roller + ink roller sets for offset printing; choose coating rollers and ink transfer rollers for flexo/gravure printing; choose special UV rubber rollers for UV machines.
• Select Rubber Material According to Ink Type:
  - Ordinary ink: Nitrile rubber (NBR)
  - Water-based ink / dampening rollers: EPDM
  - UV ink: Special UV solvent-resistant rubber
  - High-temperature coating: Silicone rollers
• Select According to Hardness Requirements: Dampening rollers: generally 20–35 Shore A; Ink rollers: generally 35–60 Shore A; Coating rollers: relatively hard, 60–80 Shore A.
• Check Dimensional Accuracy: Circular runout, coaxiality and finish must meet standards, otherwise ink bars and ghosting are prone to occur.
• Check Wear Resistance and Anti-Aging Properties: Prioritize vulcanization processes from major manufacturers to avoid rapid wear and deformation.

 2. How to Choose Anilox Rollers
•Select Screen Count According to Printing Precision:
  - Carton / rough printing: 200–400 lpi
  - Adhesive labels / tags: 400–700 lpi
  - High-precision picture albums: 700–1200 lpi
• Select Material According to Ink Type:
  - Ordinary water-based ink / solvent ink: Metal anilox rollers
  - High-speed, wear-resistant, long service life: Ceramic anilox rollers
  - UV ink: Ceramic anilox rollers are a must
• Select Cell Volume (BCM) According to Ink Layer Thickness: Large solid areas → high BCM; Fine dots and text → low BCM.
• Check Processing Technology: Prioritize laser engraving + precision polishing for uniform cells without burrs.

How to use:

Usage Specifications for Printing Rubber Rollers
1. Clean the release agent on the surface of new machines/new rubber rollers before mounting on the press.
2. Adjust the pressure to be uniform and moderate, not too tight, to avoid rubber roller deformation.
3. Release the pressure when the machine is shut down for a long time to prevent permanent deformation.
4. Clean with special cleaning agent every day to avoid ink drying and hardening.
5. Avoid direct sunlight, high temperature and grease pollution.
6. Replace or refurbish immediately if surface cracking, peeling or vibration is found.

Usage Specifications for Anilox Rollers
1. Check whether the cells are clogged or damaged before mounting on the press.
2. Adjust the doctor blade pressure to be moderate to avoid scratching the ceramic layer.
3. Clean immediately after printing to prevent ink from drying and clogging the cells.
4. It is better to use special anilox roller cleaning agent + ultrasonic cleaning.
5. Avoid bumping and scratching the roller surface.
6. Regularly check the cell depth and replace in time if wear exceeds the standard.

Q1: Uneven inking on rubber rollers and appearance of ink bars
Uneven pressure, eccentric rubber rollers, surface aging or unclean cleaning; readjust the pressure, grind or replace the rubber rollers.

Q2: Swelling, deformation and ink adhesion of rubber rollers
Mismatch between rubber material and ink/solvent; replace with solvent-resistant rubber rollers or adjust the cleaning agent

Q3: Unstable water supply of dampening rollers, too much or too little water on the plate surface
Inappropriate dampening roller hardness, rough surface or improper pressure; replace the dampening rollers or re-grind them.
Q4: Surface cracking, chipping and degumming of rubber rollers
Aging, high temperature or chemical corrosion; re-cover the rubber or replace the rollers.
Q5: Cell clogging, insufficient inking and lightening of color
Dried and hardened ink clogs the cells; clean with ultrasonic immediately and strengthen daily cleaning.

Q6: Mottled and uneven solid printing
Mismatched anilox roller screen count, too low BCM or uneven doctor blade; replace with a suitable anilox roller or adjust the doctor blade.
Q7: Fast wear and short service life of anilox rollers
Use of inferior ink, excessive doctor blade pressure or improper cleaning; switch to ceramic anilox rollers and standardize operation.
Q8: Stripes and ghosting in flexo printing
Damaged cells, uneven engraving or roller surface vibration; test the precision of the anilox roller and replace it if necessary.
