During the passage of the sheet through a printing press, the freshly printed side of the sheet comes into direct contact with the sheet-transfer cylinders; in perfecting, after the turn, the freshly printed side of the sheet is additionally pressed onto the impression cylinders of the following printing units. in order, nevertheless, to be able to print to a consistently high quality, it must be ensured that there is as little buildup as possible of printing ink on the outer cylindrical surfaces of sheet-transfer cylinders and impression cylinders. A sheet-guiding foil (2) as dressing for such cylinders is therefore proposed. The surface (1) of said foil is textured (3) and is provided with an oleophobic, wear-resistant and incompressible silicone layer. The good ink-removal characteristics of the foil result in a minimal buildup of ink on the sheet-transfer and impression cylinders. <IMAGE> |
