Speed up your wash-up cycle and keep your ink rollers spotless with this purpose-built replacement wash up blade for the Komori L420 sheet-fed offset press. Designed as a direct drop-in component for the automatic wash-up system, this blade removes ink and residue cleanly in a single pass, cutting downtime between color changes and at end-of-shift cleaning.
Why Replace Your Wash Up Blade?
A dull, nicked or hardened wash up blade leaves ink residue on the rollers, forcing extra wash cycles, wasting solvent and press time. Over time, a worn blade can even scratch the roller surface. This replacement blade restores full-contact wiping performance, helping you achieve a clean roller train faster and with less solvent consumption. It’s an affordable, easy-to-install spare part that directly impacts your pressroom efficiency.
Product Highlights
· Perfect Fit for Komori L420 – Blade length, thickness, mounting hole pattern and edge profile match the factory wash-up unit. Slides straight in, no modifications needed.
· Solvent-Resistant Material – Manufactured from a specially formulated polymer or steel alloy (depending on design) that withstands repeated exposure to wash-up solvents, blanket washes and cleaning agents without swelling or cracking.
· Consistent Wiping Edge – Precision-ground or molded straight edge ensures full-width contact with the ink roller, capturing ink and residue uniformly across the entire roller face.
· Long Service Life – Excellent wear resistance means fewer blade changes, even in high-volume print shops running multiple shifts.
· Reduces Ink Contamination – A clean, square edge prevents old ink from being re-deposited onto the rollers, improving color purity on the next job.
· Quick Changeover – Replacing a worn blade takes minutes. Stocking a spare blade minimizes production stops.
