Gravure printing meets the challenges of short live (bottom)

Reducing the consumption of film, paper, plastic used in a car, or preparing for work (including adjustment of tension, adjustment of colors, and printing registration), but leaving expensive printing equipment idle, Some may be commonplace, but whether it is material, energy or time waste, it will have a negative impact on production. Anything that affects production should be avoided as much as possible so as to maintain a high profit margin. We can roughly divide the cost of packaging materials into the following components: material costs, labor, energy (which is a fixed component), and processing costs. Let's take a look at what we can do to reduce consumption in print production. The cost of materials, inks and adhesives accounted for almost 70% of the selling price of printed materials. It can be seen that any increase or decrease in consumption will have a great impact on profits. The fierce market competition has made the profits of the printing factories thinner and thinner. Therefore, it is necessary and feasible to reduce the consumption to ensure profits. Listed below are several ways to reduce the cost-effectiveness: 1. The machine design is more compact, reducing the reel printing stroke by about 30%. In addition, some auxiliary designs are also made. For example: The drying box adopts a shutter type switch system. The use of an efficient opener with an open end; temperature difference controlled/maintained at +1°C; design of air supply, recovery, and discharge; drying ovens of different lengths to meet the requirements of the smallest print stroke print. 2. With the new ink supply system, no matter how fast the speed is, it can ensure the ink's good condition and reduce the occurrence of ink splashing, thereby reducing the amount of ink used. 3. Improvements have been made in man-machine interaction, making it easier to clean, operate, and maintain the machine. 4, improved tension control system. 5, gravure printing machine can also be equipped with advanced registration and quality control system. The registration and quality control devices are provided separately as an option, which is the first time in the gravure printing industry. This is mainly based on the user's interests. Users can choose according to their own situation: Separately provide register control The system can avoid the occurrence of events such as mutual shirk responsibility due to different suppliers; it can also train different machinists separately and simultaneously. Supporting the provision of register control system, as it is an integral part of the gravure printing press, its control accuracy and control level have greatly improved. 6, S3400 QS quality control system, with the use of register control system. 7. The advanced intelligent printer operation and register control interface can avoid repeated input of parameter values ​​and simplify data exchange. 8, in order to match the use of register control system and cold seal detection system, also designed a unique device. Always keep in mind: in the roll change process will result in about four meters of waste; the same job, each print will cause a long waste of several printing strokes; new live boot printing will also cause several long print strokes waste. In production, these consumptions should be minimized. More adapted to the needs of the short live market In the "quick change" aspect of gravure printing, Schiavi can be said to be a pioneer, such as its non-stop quick changer, which can perform roll change operations within 80 seconds. 1. A new type of rubber embossing roller with a sleeve design can be quickly replaced within 1 minute without any tools. It takes 30 minutes before. 2. Squeegee blade holders are pneumatically mounted. The blade can be replaced in less than 1 minute without any tools. Moreover, the pressure of the squeegee is reduced in design, the service life of the printing roller is prolonged, the roller is easier to clean, the quality of the printed matter is higher, and the printing speed is faster. 3. Computer-controlled management of printing presses, capable of storing and recalling major operating parameters such as tension, temperature, air circulation rate, speed, and registration. With all of these devices/equipment, plus some minor adjustments/trimmings, the eight-color intaglio printing press can be replaced within 45 minutes. However, for those prints that are only a few kilometers long, this speed may not be fast enough. Therefore, a new type of machine has been specially designed for this extremely short life. This new type of machine uses a computer-controlled automatic cleaning of the printing cylinder and the ink tank; in order to reduce downtime, the squeegee is also controlled by a computer. In Germany, there are currently three such machines in production. Conclusion 1. Rotary gravure printing still has vitality and competitiveness, and in the face of the challenges of other printing methods, it will never retreat and compromise. 2. Gravure printing should promote its own unique advantages, like flexo printing and current digital printing. 3, before selecting the best printing process, the printing plant should fully understand the advantages of gravure printing. With the progress of the times and the development of science and technology, more new things will emerge, and the printing industry is no exception. In the future, there will inevitably be competition among various printing technologies. Facing the new demands and challenges brought about by the new millennium, this will also provide us with new solutions and countermeasures.
