Abstract:
Provided is a printing apparatus that includes: a sheet path for moving a print substrate; a decurling station positioned along the sheet path and the decurling station. The decurling station includes an indenting roller mounted for rotation around a first longitudinal axis thereof and on a first side of the sheet path, and an elastomeric roller mounted for rotation around a second longitudinal axis thereof and on a second side of the sheet path. The indenting roller includes an indenter shaft and a an anti-contamination coating disposed on the indenter shaft, wherein a drop of aqueous ink exhibits a sliding angle of less than about 30° and a contact angle of greater than about 40° with a surface of the anti-contamination coating.
