Troubleshooting

Ink may appear to be drying out in the roller train or press seems to be unable to adequately supply the proper ink water emulsion to the plate.

The shadows and tight reverses start to fill in and become “plugged” with ink during the run.

Fine lines and dots disappear. Work loses clarity and printing becomes streaky with weak solids and densities. Images disappear.

Plates become sensitive during the run, and will start to transfer ink in the non- image area.

Non-Image/image area piling is ink and paper fiber build up on the blanket that prevents proper offset.

Ink or other material accumulates on the blankets or transfer cylinders on the outside dimensions of the paper stock being run.

Picking or lifting of paper coating onto blankets, plates, and rollers.

pH and conductivity drift out of specification

Printed solid areas are not uniform or smooth in appearance. Ink density is uneven or light.

Fine droplets of ink formed on the rollers fly off creating a mist.
