Whether in label or package printing, brand manufacturers make uncompromising demands. Not only a consistent quality control, but also the subsequent defect elimination is essential in this context. Even better, if reaching those quality goals also has a positive impact on production performance. eltromat GmbH, manufacturer of innovative systems for optimising print processes for over five decades, introduced its latest 100% inspection system “twin_check narrow” at the drupa 2012. According to the producer, the concept of the established 100% inspection system for wide web applications has now been transferred to the field of narrow web printing. “twin_check narrow” is completed by workflow solutions, which make complying with quality guarantees effective and efficient.
A high-performance 100% print inspection is the pre-requisite for a well-organised quality workflow. The inspection system “twin_check narrow” allows a high-resolution inspection. According to the provider located in Leopoldshoehe, Germany, it reliably detects process-related as well as sporadic print defects. The system is designed for all established printing methods as well as for the whole range of print substrates – including reflecting and transparent material.
In addition to an extensive defect classification, masking functions with useful possibilities of sensitivity adjustments, “twin_check narrow” also provides the fully-integrated functionality of a 100% web monitoring.
eltromat promises even more process security with its “PDF plate_auditor“. Already during the set-up phase, this module compares the pre-press PDF to the print image and thus recognises defective or wrong printing plates/cylinders at an early stage.
In order to reliably eliminate waste in a downstream process, the module “event_logger“ logs all defects in a protocol, which, according to the producer, can also be used for additional in-house analyses due to the interchange format XML.
Not every deviation which is of interest during the printing process automatically causes waste. In an optional step, the software solution “quality_assistant“ offers the opportunity to re-evaluate the defect protocol according to harmonised internal quality criteria and to classify defects as being irrelevant if necessary.
The module “rewind_navigator“ for example controls the rewinder on the basis of the defect protocol in a way that allows it to operate at maximum speed and to stop precisely at the spot where waste is to be eliminated.
