Troubleshooting

Streaks, tracking, or ink smearing due to the folding or finishing operations through mechanical contact.

Excessive paper lint and or filler depositing in both the image and non-image areas of blankets and or plates.

Ink is transferring from one page to the next or book to book when completed.

Ink pigments breakdown in fountain solution causing a light discoloration in the non-image areas

Ink backs away from ink ball. This causes the print to become starved for ink

Ink takes on too little or too much press mix during emulsification.

During the printing operation the highlight dots start to form into a “donut” shape, where the center of the dot no longer is transferring ink.

Irregular “donut” shaped white spots surrounding a small spot of ink.

Glazing is the result from the formation of insoluble components from the ink, paper, and water mixture. Usually occurring on rollers and blankets.

Slurring is the filling in of halftones and at the back edges of solids. Mostly occurs on coated papers and is caused mainly by paper slippage in the impression nip between plate and blanket or blanket and paper.
