Weitmann & Konrad presents their developments in drupa

  • Publicado el 10 de Mayo de 2016

Weitmann & Konrad GmbH & Co. KG, the technology leader for powder spraying systems for offset printing and non-contact remoistening systems for digital printing presents current developments in the area of process optimisation at drupa 2016. Using the motto "Don`t play – work with precision" WEKO presents innovative solutions and concepts at this year's drupa facilitating process optimisation for the user both in digital printing and sheet-fed offset. The company, owner-managed for over 60 years, positions its products between printing and further finishing thus bridging the gap between these two processing operations.

"We constantly continue to develop our products – especially in the area of powder spraying for offset printing. Alternative technologies, such as LED UV print – promising to manage without powder – meanwhile press into the market. However, high product quality, frictionless production processes and high processing speeds make an extremely thin, precision-applied powder coat indispensable for further processing of the printing products. Our passion is to improve good products even further," explains Marcel Konrad, managing partner of WEKO.... "and this always includes a touch of powder."

The WEKO powder spraying technology is employed worldwide by all significant manufacturers of offset printing presses. The current AP series sets highest standards for application efficiency, repeat accuracy and cycling of the powder application precisely for each sheet. Can this quality still be topped? The WEKO engineers answered the question in the affirmative and developed the STEP application technology.

 

The objective consisted in designing a powder spraying system that cycles as exactly and precisely for each sheet as an electronic signal... and that at maximum printing speeds. To achieve this goal, powder cycling hat to be brought as closely as possible to the sheet. This has been accomplished with WEKO STEP. The powder is metered exactly to the milligram into an air flow. Cycling only takes place immediately before the sheet. Nearly digital individual sheet cycling is thus possible even at maximum speeds of up to 22,000 sheets/h. The new STEP technology will be presented to the interested technical audience for the first time at the drupa 2016 as developmental study.

Minimum and repeatable powder application guarantees the quick, process-optimised further processing for oil-based but also UV applications and reliably prevents offsetting of print sheets as well as glass plate effects. "Modern powder spraying systems combine economy and ecology in a unique manner", says Konrad. The WEKO experts offer support worldwide with the choice of WEKO Application Systems and the integration into the production process. They help customers enjoy clear benefits with utilisation and costs. Comprehensive services, such as test at the WEKO technical centre and high WEKO service standards, complete the WEKO offering. In addition to the main office near Stuttgart WEKO maintains two production locations in Germany and Brazil, own sales and service subsidiaries in Italy, the United Kingdom, the U.S., and Brazil. Furthermore, WEKO collaborates worldwide with agencies marketing the products and offering the proven WEKO service standard in addition.
