Technical inventory of Heidelberg drying monitoring system

1. Printing jobs using the glazing process can obtain accurate data on drying quality

2. Save energy and protect the environment

Heidelberg Printing Machinery Co., Ltd. (Heidelberg) launched the world's first drying monitoring system, adding a new member to the Star (star series) peripheral equipment family. With the help of innovative sensing technology and online process monitoring, printing press operators can objectively and accurately obtain the drying quality information of paper varnish coatings. This drying control system can measure the amount of varnish used in the glazing unit, and use the sensors installed in the take-up unit and the drying unit to record all drying-related parameters, including varnish water distribution, air volume, and the introduction and export of air. Temperature and humidity. The monitoring system uses these parameter information to provide recommended operating guidelines for printing equipment, indicating that a lower or higher amount of desiccant should be entered to achieve the best glaze drying effect.

Heidelberg Drying Monitoring System: Innovative sensors and measurement technology application to achieve optimal glazing drying settings.

The application of this drying monitoring system will help to prevent the adhesion of printed sheets due to insufficient drying or yellowing of the varnish layer due to excessive temperature. The overall energy consumption has also been significantly reduced. A survey in Heidelberg shows that because printing press operators have always been unable to obtain objective data to evaluate the quality of drying, the output of most drying equipment is 20% to 25% higher than actually required.

This drying monitoring system will be first installed on the Heidelberg Speedmaster XL105 printing press in September 2008, and plans to gradually spread to other models of printing presses. At present, the monitoring system can only monitor the drying quality of water-based varnish. It is not yet possible to achieve online measurement of ink, or online measurement of UV ink when UV glazing is selected. Heidelberg plans to integrate the final version of the drying monitoring system into the central printing control system for display at the 2008 Drupa Printing Exhibition.

Really environmentally friendly

In addition to providing a lot of convenience in production, the drying monitoring system is more stable and reliable, and it can also effectively reduce the energy consumption of the printing press. It should be known that the energy consumption of the dryer accounts for about 40% of the total energy consumption of a printing machine equipped with a glazing unit. This is of great significance to printing plants keen on green printing. In many countries, printing companies can also apply for environmental protection bonuses or environmental loans with preferential interest rates to purchase printing equipment equipped with drying monitors.

Heidelberg promotes "ecological printing"

Since 1992, environmental protection has become an integral part of Heidelberg ’s corporate policy. In 1996, Heidelberg's production base in Amsteden became the first printing equipment company to receive an ecological certificate. At present, all the production bases for sheetfed offset printing in Heidelberg implement the ISO14001 standard environmental management system. Heidelberg not only attaches importance to environmental protection in the assembly and production process of printing presses, but also strives to develop new printing machines with more environmentally friendly performance. For example, the new Speedmaster XL105 can increase production capacity by 30% with the same or less energy consumption. The main components of the Star series also reduce the environmental impact of the printing process. The powder spraying star AP500 printer reduces the amount of toner and dust. Air Star can reduce energy consumption by 30-50%. On the basis of the same energy consumption, the performance of the new drying star dryer is further enhanced.

Our Cling Film is wildly used in industry and household. They are water proof, good appearance, transparency, non-toxic, tasteless and strong tensile strength. The Fresh Film could lock the freshness of  food, fruits and vegetables and keep moisture. The stretch Film is good for industrial packing, could protect the products from away from water or dust.
