paper conditioning for toner-based printing systems. This is the basis for the newly developed WEKO DigiCon for inkjet printing. Walter Digital successfully uses the WEKO-DigiCon paper conditioning unit for remoistening on the Ricoh VC60000 for high quality print products. Many digital printers are familiar with
wavy print products. Nowadays, however, print shops no longer have to accept these quality losses. After the printing process, the paper must lie flat and be able to be processed further without problems. The solution is to return the moisture content to the paper that it has lost through drying
The quality assurance of paper conditioning W
EKO Weitmann & Konrad has many years of experience with the WE-KO-RFDi for
processes. WEKO offers a conditioning unit for remoistening the paper web for digital printing machines of all renowned manufacturers – the WEKO DigiCon. Paper fibres shrunk through drying leads
to wavy print products with an unattractive appearance. The WEKO-DigiCon supplies the paper with a precisely defined amount of water and thus relieves the paper fibres. This ensures flatness, avoids static charges, ensures high product quality and maximises the processing speed. The heart of the WEKO-DigiCon are special spray discs (rotors). They rotate at a high speed generating a uniform stream of finest micro-droplets. Adjustable sliders create spray fans that are arranged seamlessly side by side and ensure uniform remoistening.
Walter Digital GmbH from Korntal-
Münchingen is already permanently using a WEKO DigiCon validated by the manufacturer on its Ricoh VC60000 at the Sindelfingen site. Walter Digital belongs to the Heer Group and specialises in digital printing and finishing with an extensive machine park and also offers highly efficient logistics processes for its customers. “This is about efficiently producing high-quality print products through a high degree of process auto- mation, offering customers low unit prices and personal service for changing jobs with short runs. WEKO DigiCon also contributes to achieving these goals,” explains Felix Walter, managing director of Walter Digital. Walter Digital mainly prints catalogues and operating instructions on the Ricoh VC60000, but also banners, flyers, posters, brochures, saddle stitching or adhesive binding (hardcover, softcover). The production of short and very short runs in large quantities is a very relevant market for Walter Digital. Diverse jobs with different contents and scope but with the same design are bundled on the press. “Since we have remoistened the paper web with the WEKO-DigiCon, the quality has become much better, and wave formation is no longer an issue. In addition, remoistening has a positive influence on finishing, as the maximum speed can be achieved on the offline cutting line,” adds Thomas Freese, site manager for web-fed digital printing.
