The best ink balance and ink system
Ordinary web reel offset press is usually used by two plates of ink roller, the machine is used by the three version of the roller, which printing ink layer is more uniform and more delicate. The open color fountain and the overall color setting capability of the 24 independent printing areas in the paper width direction are realized by a programmable non-linear algorithm, one for inking, one for dampening, ensuring that the ink balance is Best state. Both the fountain roller and the fountain roller are driven by a separate maintenance-free brushless motor, both in linkage with the host and individually.
The string roller is cooled by the structure, which effectively controls the ink temperature.
Water transfer using the whole business machine water roller continuous water, water more easily controlled.
Ink volume control using digital ink remote control system, ink on the ink button on the use of ink under the control of the slider under the slider structure, the ink area will not produce interference between the use of touch screen control, bar ink volume screen display The With ink preset (CIP3) interface, through the PPF or 1-bit TIFF file to generate ink preset data, by the ink key motor automatically adjusted to the bit. The best ink density control and printer speed synchronization greatly reduces the ink time and paper loss.
The system also has an adaptive function. Since the CIP3 ink preset data automatically generated according to the front plate making process is transmitted to the printing plate through the different ink transfer mechanism, the effect on the final print is different, so that the operator will Some of the ink key data to be amended, the revised data will be automatically remember and automatically adjust the next boot. After many times the automatic memory, correction, running, the final system will tend to do without any artificial intervention in the real automatic system, for the pursuit of quality printing provides a technical guarantee.
The entire process of the tape from the start of the paper holder to the folding machine is tightly controlled. The control measures are closed-loop tension feedback system and low-quality guided roller system for monitoring continuous web tension and compensating for introduction Amplitude difference. The appropriate tension of the format can eliminate overlay deviation, blur and ghosting problems. Equipped with monitoring center or edge of the paper positioning function, can quickly and accurately correct. Print quality is therefore higher and less wasteful.

Unique paper feed mechanism
The paper feed uses a unique gap rotary transfer mechanism, which has two rows of grippers and front gauge mounted symmetrically on the stop roller. This structure has the following advantages:
1. The impact of the machine is small, smooth running, help to improve the printing accuracy.
2. Paper in the pre-positioning at a long time, thus ensuring the positioning accuracy of the paper.
3. The paper is closed when the transfer roller is in the stationary state, and the paper and the jaw are gradually accelerated, thus ensuring the accuracy of the delivery paper.
The use of the overall casting of the box-type base and frame-type wall panels, highly anti-twisting strength, to ensure the overall stiffness and stability of the machine.
Scientific arrangement of drums
1. Plate cylinder, rubber roller, impression cylinder into seven o’clock arrangement, four-color printing only through the three middle delivery roller, reducing the number of paper transfer.
2. The most fundamental advantage of the machine is the use of double diameter impression cylinder and transfer roller structure, paper curvature is small, smooth delivery, especially for more rigid paper printing. There is a special anti-rubbing material on the paper roll.
3. The surface of the impression cylinder is sprayed with stainless steel. The transfer of the impression cylinder and the transfer roller is done after all the embossing is completed. Even the largest sheet of paper is such that the paper is not affected by other forces. The accuracy of the paper transfer and does not produce rubbing and curling phenomenon.
4. The use of secondary clutch pressure control device, eliminating the first boot can only print half of the phenomenon.
5. Plate cylinder registration adjustment using electric remote control mode, that is, on the console can be on each or all of the plate cylinder radial adjustment. According to the need can also be equipped with skew register adjustment device (cable cut version).
6. Each printing unit is equipped with semi-automatic plate loading device, which can effectively reduce the replacement time and improve work efficiency.
Novel ink system
The ink system has an ink arrangement that meets the requirements of extremely high printing quality. Five by the version of the roller diameter varies, which is the first by the plate roll both on the water and ink, can quickly achieve ink balance.
The use of single-line ink transfer method to transfer ink to the printing plate group, thus adjusting the reaction speed, reduce bad pieces and shorten the cleaning time.
This open-type ink transfer device effectively avoids the phenomenon of heat storage in the operation of the ink roller, even if the long version of printing is almost no need to re-adjust the amount of ink set.
The preferred arrangement of the plate roll, the string roller, and the two ink rollers on the ink-in-one roll, effectively suppressing the “ghosting” phenomenon.
It is very convenient to adjust the pressure of the printing roller, and when the thickness of the printing drum is changed, the pressure on the four presses can be adjusted by the hand wheel with a pressure display.
Alcohol dampening system
Moisturizing system using alcohol dampening way. Alcohol can reduce the surface tension of water, thereby reducing the amount of water used to effectively control the deformation of the paper, making the overprint more accurate.
The system also has one of the biggest features, namely the use of continuous water and ink in one version of the way, by the version of the water roller on both the water and ink, it can also be called by the version of ink roller, can quickly reach the balance of ink.
