Abstract
A device for cleaning the solution used for washing a printing press cylinder wherein the washing solution is conveyed in a circuit and cleaned by a distillation device to separate out ink residues followed by a gravity separator to separate the washing solution into its water and solvent constituents. Only small amounts of ink residues are produced in the distillation device and can be disposed of without difficulty as industrial waste. The cleaning procedure is also very efficient because, after being cleaned and separated, the water and solvent constituents of the washing solution can be separately and successively supplied to the cylinder to be washed.
