in the past, Eitex Remois- Technical Information tening systems have guaranteed high quality printed products mainly on fastrunning and wide machines. The WEBMOISTER 3000 ensures high-quality products in all heatset web offset machines. Using a new nozzle concept, both lighter and heavier grammages can be remoistened at all web speeds with ultimate precision and homogeneity. The new pneumatic atomizing nozzles are capable of applying smallest water quantities without developing waste water. The modular structure of the nozzle bar allows the WEBMOISTER 3000 to remoisten paper webs in widths of as much as 3meters. The benefits: • better quality of the printed product • enhanced productive efficiency through easier finishing of the paper • cost savings through more efficient processes • small dimensions • easy operation • minimum cost of ownership WEBMOISTER 3000 Electrostatic Remoistening a* o o N

System Description WEBMOISTER 3000 Electrostatic Remoistening by Eltex Inks in heatset web offset are dried with hot air. In general, this process lowers the water content of the paper, sometimes to such an extent that the paper dries out completely. This can cause severe problems in finishing. Electrostatic remoistening raises the water content of the paper back to the original (and necessary) value. The benefits of the system: • easier processing and handling of perfect-bound products with cross-grain or long-grain pages • no waves caused by gluing • no fiber breakage • optimum paper run...

Water content of the paper Most papers used in heatset web offset printing are delivered with a water content of between 4 and 5%. During printing, this percentage tends to increase by about half a percent. The subsequent drying step lowers the water content, sometimes desiccating the paper completely. When setting the water quantity for remoistening, the paper grade and the grammage must be taken into account. The system notes all the data through the appropriate setpoint settings. The WEBMOISTER 3000 allows even the smallest water quantities to be metered exactly. The result: ultimate...

High voltage field The reliable Eltex charging bar is used to generate the high voltage field. The shockless bar guarantees the optimum field build-up and field distribution. The actual high voltage is generated by an Eltex high voltage generator. With its new connection concept and by monitoring important functions (high voltage cascade, calibration, short circuit current, voltage and current limitation), the generator provides ultimate standards of safety. Operation The system is operated and controlled via a touch screen. Key symbols with unique function assignments guide the operator...
