Print Mottling

 
Problem:
Print Density is Uneven
Causes:
Too much impression
Too much ink being carried
Low viscosity ink may look mottled on papers with uneven holdout
On some stocks, transparent inks will show more mottle
Solutions:
Check Blanket Impression and plate to blanket pressure
Run a stronger ink to permit a thinner film
Higher viscosity ink will have less absorption and reduce mottle
Use a more Opaque ink
