Heidelberger's Speedmaster duplexer

The ever-increasing production efficiency of the double-sided printing press has given sheet-fed offset printers a good performance in a highly competitive market.

Heidelberg's Speedmaster duplexer has changed the commercial printing market dramatically. The basic concepts of these presses constantly improve the quality and productivity of double-sided printing. Heidelberg's slogan is "One-pass productivity," which means that at a print speed of 26,000 sheets per hour, paper can get excellent double-sided print quality by passing through the press once. Fast job preparation time and powerful production capacity make the double-sided printing press the most efficient production equipment. All Speedmaster models use a three-roller page turning device to ensure accurate positioning registration.

Previously, double-sided printing was the best choice for job production with low quality but quick delivery, and many jobs could not be produced using this process. For this reason, Heidelberg is determined to concentrate its efforts on the development of a better-performing, more efficient double-sided printing press for the commercial printing market. The wide-format, multi-unit press series clearly achieves this goal. The breakthrough in paper control technology enabled the printer to realize the process of guiding the paper to complete double-sided printing and reliably transport the paper to the delivery table at high speeds, which is crucial for obtaining high-quality prints.

Another necessary condition for the successful completion of double-sided printing is that the inverted ink film on the impression cylinder is minimally disintegrated after the paper is turned over. To solve this problem, Heidelberg invented a replaceable roller cover called PerfectJacket. This high-grade steel sleeve has an irregular middle layer coated with titanium alloy covered with a silicone surface. The new PerfectJacket roller cover can bounce ink beads without forming an ink film on the roller surface. It can also be applied to the old model Speedmaster machine, thus retaining the value of the old machine.

The main advantage of PerfectJacket is that the roller surface and the ink have little effect on the quality of the print, so the effect is better.
1. There was no visible spotting on the ground just after printing. (a defect of the old drum surface)

The Heidelberg Speedmaster press can be easily operated with the intelligent CP2000 central printer control system. Its open interface is suitable for the company's entire digital workflow. The InkLine automatic ink system ensures that the fountain solution contains a constant amount of ink.

2. The scope of printing materials is more extensive. As the amount of ink deposited on the surface of the impression cylinder is small, the production efficiency is increased by 10%-15%.
3. One shift only needs to be cleaned manually.
4. Print up to 100,000 sheets even without the impression cylinder.

In duplex printing mode, there are more printable job types.
Printing thicker ink layers becomes possible.

The latest CP2000 central printer control system can reliably control the job preparation time and press operation. It integrates the Heidelberg Speedmaster press into a seamless CIP3-based digital workflow, extending from prepress to printing. The operator conveniently controls the functions of each printer, such as the control of the amount of ink and positioning register, the control of the paper size, and the like through the touch screen. For jobs that need to be printed multiple times, the job parameters can be stored and recalled when needed, making it easier to optimize quality and eliminate errors. The user interface with a clear menu structure can remind the operator of the current printer status at any time, allowing the operator to clearly know when the printer needs to be adjusted, and when it is necessary to pull out the printed sheets for inspection. Send all printer data to the service department of Heidelberg AG via modem and telephone line to get the solution to the problem. The printer can also receive ink preset data from the Plate Image Reader or the Prepress Interface to speed up job preparation and reduce startup waste. With ManagementGate, printers can be connected to industry software, enabling direct connection between printers and printer orders and production management systems. Job preparation data can also be sent directly to the press to obtain real-time production data that can be used to calculate the resulting production costs.

ImageControl, an innovative quality control system, is an advanced system for checking the quality of printed products on the outside of the printer. It is a supplement to the CP2000. It is unique in its use of spectrophotometric methods for measuring printed sheets.

Various sizes of Heidelberg double-sided printing technology:
Printmaster GTO 52, Speedmaster SM 52, Printmaster PM74, Speedmaster SM 74, Speedmaster SM 102.

Replaceable PerfectJacket, installed on the impression cylinder, can greatly improve the quality of double-sided prints. The innermost layer is a steel shell, the middle is a concave titanium alloy coating, and the outermost is a silicone outer coating.

In many applications, the measurement of the inside of an image is free from the application of color patches. The deviation from the specified reference value can be obtained by measurement, and adjustment suggestions are automatically generated based on this value. The recommendations are then passed on to the press, completing the adjustment of the ink zones on each printing unit at a time. With ImageControl, stable production of high-quality standard prints in the pressroom becomes a simple and easy task.

Typically, multi-machine duplex printers are involved in production 24 hours a day, 7 days a week. The production capacity is astonishing: Printing 30,000,000 printed sheets in one year is a very common thing, at least the output of two single-sided printing presses. Various Star accessories can be used to keep the printer at a constant temperature without stopping the machine.

Some jobs require partial or full coverage of the sheets. Adding a coating unit to Heidelberg's multi-machine duplexer can solve the problem, but it requires only the selection of the appropriate printing plate and ink. In addition, liquid coatings can also be applied. It should be noted that for different coating types, the corresponding drying system must be selected.

Along with the Speedmaster duplexer, Heidelberg continuously improves the quality standards of the sheetfed offset system. Double-sided printing - "One-pass production efficiency" - has entered a new era of quality and production efficiency.

Using the ImageControl to perform spectral measurements on freshly printed press sheets, the best prints can be produced quickly and accurately. Measured is a real page, not a color scale.

The quality of the printed matter is ultimately determined by the operator. Modern technology from Heidelberg has greatly increased production efficiency and quality.

In his bedroom, the "The Death of Cenchirias" was painted by the French artist Sophie Rude in 1822. In this work, the Greek beauty Peirene is mourning her son. Her son was killed in an accident by the goddess Diana's sword.
