Poor Scuff Resistance

Ink film not fully dry

Make sure the ink film is thoroughly dry. An oxidizing ink should take 24 to 48 hours to thoroughly dry. Many variables: substrate, fountain solution, ink coverage, ambient conditions

Ink is over-emulsified

Check pH and conductivity and Brix level of fountain solution. Run less fountain solution to achieve proper ink/water balance

Chalking – ink not binding to substrate

Certain papers can be very absorbent leaching away the ink vehicle and leaving the pigment unbound on the surface
