In a single blade ink system or dual blade ink system, the blade removes the excess ink from the cylinder or anilox roll to create a uniform layer of ink to be transferred to the printing plate. The blade/anilox combination is designed such that it is (chiefly) the blade which wears away, not the anilox roll. The doctor blade is a relatively cheap and disposable consumable, while the gravure cylinder or flexo anilox is a more expensive component of the press. Typical materials for the bla… Websolar cells using a doctor blade method.
