Technical Acceptance of Post Press Machines

A basic part of our service offers are technical acceptance tests for all equipment used in the graphic arts industry, e. g. CtP plate setters and plate processing units, printing presses and of course post-press equipment of all kind. The main focus of the acceptance test is the product. The processes and products are evaluated with objective metrological analyses with representative samples. Of course we can offer also customised evaluations, e. g. for presses with carton ability and UV curing. We consult and support you in preparation of the testing and controlling procedure as well as the tolerances to be used during the acceptance.

The processes and products are evaluated with objective metrological analyses with representative samples (products in different stages of production) taken by the SID personnel. For certain processing steps special samples will be printed, equipped with particular measurement patterns to evaluate the accuracy, e. g. folding, cutting, creasing. It will be checked if the technical parameters are within the tolerances given by the standards. For a representative result it is advantageous to run the machine under normal conditions six weeks in advance to the acceptance test. The machine supplier has to declare the readiness for the acceptance. 
Additionally we analyse the degree of efficiency by a detailed stoppage assessment. The duration of an acceptance test depends on the complexity of the system. A folding machine needs approximately 4 hours on site, an adhesive binder possibly more than one day. A service technician of the machine supplier shall assist during the acceptance test to carry out settings and adjustments instantly.
