How to keep your ink and dampening rollers in top condition

Clean, deglaze and condition ink rollers to prevent plate blinding, interference from chemistries like calcium carbonate and increased PH and conductivity spikes in the fountain solution. Below are some easy-to-follow roller maintenance tips.

Tip 1

Paper chemistries like calcium carbonate interfere with the printing process. You should remove these contaminants so that the rollers are clean and able to accept ink and water.

Agfa product: Decal Plus

Tip 2

Plate blinding or loss of ink receptivity issues are mostly caused by improper roller care. It's best to remove all of these contaminants so that the rollers are clean and able to accept ink and water.

Agfa products: Xchange (deep cleaning), Ink stripper Plus (extra powerful) 

Tip 3

The daily use of Reviverol Plus  or weekly use of Reviverol Extra will keep your rollers in good condition. And it will limit the need for extra cleaning to a minimum.

properly-cleaned-roller-surface

The goal is to get the roller surface clean so that the proper transfer of ink and fountain solution can take place to produce quality printing. A properly cleaned roller surface will look like this.
