Emulsification

Emulsification - Occurs when ink picks up too much water. Ink becomes shorter and won't distribute well on ink rollers. As ink collects more water, you will start to see light, uneven copy, snow flaking (little white flecks appear in solids), scumming, stripping, tinting, toning and picture framing.

Causes
Remedies
Dampener setting is too high
Reduce amount of solution being applied to plate.
Fountain Solution is too acidic
Reduce amount of concentrate or switch to less acidic fountain solution.
Fountain solution Conductivity is too high
Remix fountain solution to lower conductivity.
Adverse chemicals in tap water
RMix fountain solution with distilled or RO water. Never use water from a water softening system as these systems add unwanted salt to the water.
Poor roller contact (mechanical problem)
If dampener roller stripes are not set properly, water can collect in one end of the system more than the other. If inking rollers are not striped properly, too much ink will be needed to transfer it, and then more water will be added to compensate.
