The information about minimum dot indicates what is the size of the minimum printing dot that appears on the plate.

Physics

Ink builds around small print elements like dots and small type creating hollow shapes like donuts. Inked dots perforate ink layers that were printed by previous printing groups. This happened on external print on plastic film, solvent based inks, flat-top plate, sequence YMCK. Combined action of excessive impression with high ink volume and low viscosity
