The wash up blade comprises of a thermoplastic, which can be machined with very narrow margins. Therefore, wash-up blade is furnished with a special profile, which runs to a very specific contact zone between the wash-up blade and the roller and thus the ink and cleaning agent deposits can be scraped off cleanly.

This problem does not come up with the new generation wash up blades. They wear away slowly and equally. Thanks to the flexibility of the material, a necessary but not excessively high pressure is used onto the roll.
