Troubleshooting Guide - Pressroom Conventional

On Press Issue: Slurred Image

Potential Causes

Too much ink on rollers

Solution: Adjust packing to equalize diameters of cylinders. If diameters differ, the resulting different speeds between cylinders causes slippage resulting in a slurred image. 

Loose, uneven, or soft blanket

Solution: Tighten blanket clamps, adjust packing, or replace blanket. 

Excessive play in gears and bearings of plate and blanket cylinders

Solution: Adjust to manufacturers specifications.

Running too much ink on coated substrate

Solution: Reduce the amount of ink carried. Increase ink strength to allow carrying less ink on rollers.
