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
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
