Tendency of paint film to take on the imprint of an object that is placed on it, i.e. a shelf, table or windowsill with books, dishes or other objects on them.
Use top quality waterbased semi gloss or gloss paint. Low quality paints can have poor print resistance, especially in warm, damp conditions. Oil based paints also have excellent print resistance. Make sure the recommended cure time is allowed before the painted surface is put back into service. Cool or humid conditions require more curing time.
