Maximizing Uptime: The Komori Press Roller Maintenance Guide

For printing press owners operating Komori equipment, the roller train is the heart of print quality. Whether you are running a Lithrone or a Spica series, consistent ink laydown and dampening depend entirely on the condition of your rubber rollers. Neglecting maintenance often leads to dot gain, ghosting, and premature failure of the roller surface.

The Weekly Roller Inspection Checklist

• Surface Integrity Check: Inspect the rubber for cracks, pits, or signs of swelling. Swelling is often a side effect of incompatible wash-up chemicals.
• Hardness Verification: Use a Shore A durometer to check for hardening. If your rollers have exceeded the manufacturer’s recommended hardness range, they will lose their ability to hold the ink film properly.
• Setting and Nips: Check roller nips weekly. Uneven pressure causes friction heat, which rapidly degrades rubber compounds. Use gauge strips to ensure uniform contact across the entire length of the roller.
• Glazing Removal: Ink buildup and calcium deposits create a ‘glassy’ surface that repels water and ink. Use a dedicated de-glazing paste during your weekend maintenance cycle to restore the surface energy of the rubber.

Common Komori Roller Issues

Komori presses are precision-engineered. When you notice variations in density, it is rarely the machine—it is almost always the rollers. If you see ‘streaking’ on the substrate, check the alignment of your form rollers. If the dampening system is failing to maintain a clean non-image area, your metering rollers may be glazed or worn beyond the point of effective adjustment.

When to Consider Re-rubberization

Even with perfect maintenance, rubber is a consumable item. If you find yourself constantly adjusting settings to achieve a consistent print, the rubber has likely lost its elasticity. Re-rubberization is a cost-effective alternative to buying new OEM sets, provided the core remains in good condition. We specialize in precision grinding and compound matching to ensure your rollers meet the exact geometry required for Komori presses.
