With the automatic wash up system, washing sequences are controlled by a microprocessor. The wash-up cycle is operated with sequences and time frames already pre-set in a program. However, some of the parameters can be altered, independently for each printing unit, by accessing a set up function and can be recorded with a job code (recipe) re-usable at operator’s option. Wash up cycles are activated simultaneously, for all printing section pre-selected, with their individual parameters’ settings. This system allows precise personalized sequences replication resulting very effective with the use of different inks and thinners.
