Piling

Piling - happens when the ink becomes too short due to emulsification. Ink builds up on the rollers or on the blanket and then it becomes too short to transfer properly. Excess pigment will then build up and start to pile or cake.

Causes
Remedies
Ink emulsification
Fountain solution is too acidic

Glazed ink rollers and/or blankets
