Thin distribution in center of
pattern “horns” Worn tip Change to new tip

Thick skin on work Material too viscous Thin cautiously
Application too heavy Reduce pressure and/or use tip in next
smaller tip size
Coating fails to close and
smooth over Material too viscous Thin cautiously
Spray pattern irregular,
deflected Orifice clogged Clean carefully
Tip damaged Replace with new tip
Craters or pock marks, bub-
bles on work Solvent balance Use 1 to 3% “short solvents remainder “long”
solvents (this is most likely to happen with
material of low viscosity, lacquers, etc.)
Clogged screens Extraneous material in paint Clean screen
Course pigments Use coarse screen if orifice size allows.
Poorly milled pigments (paint
pigments glocculate) Use courser screen, larger orifice tips. Obtain
ball milled paint. If thinner had been added,
test to see if a cover screen. Incompatible
drop placed on top of paint mixes or flattens
out on the paint mixture and thinners on the
