Digital printing machines can be divided into two types: digital printing machines without plates and digital printing machines with plates. The common feature of plateless digital printing is the realization of variable information printing. The current plateless printing machine can be divided into three ways from the big aspect. Plateless digital printing machine 1. Electronic photography First, fully charge the photoreceptor (OPC), then use a laser or the like to extract the image to generate an electrostatic latent image, then cover the electrostatic latent image with toner, and finally transfer the toner image to the paper. There are two types of toner: powder and liquid. At present, most of them use powdered toner. 2. Electrocoagulation This type of printing machine is generally a printing color group. If multiple groups are connected according to the necessary number of colors, a multi-color printing machine is formed. If the turning device is added in the middle, two-sided printing can be realized, so it can be suitable for printing for various purposes. Moreover, the image quality of the printed matter is close to the continuous tone image. 3. Inkjet method The inkjet printer is a dot matrix structure composed of many nozzles. By receiving the layout information of the computer, the ink is ejected from the very fine nozzles, and the electric field controls the direction of the inkjet flight, generating images and graphics on paper. In some inkjet printers, the ejection of ink and the formation of green particles are achieved by means of charging and pressure. The application of the inkjet digital printer is very different in its speed and resolution, as well as the color reproduction area. Digital printing machine A digital printing press must have a pre-made printing plate on the printing plate cylinder, but this printing plate is made directly on the printing press. Compared with traditional printing presses, although this printing press also requires printing plates, but because it is a direct plate-making in machine mode, only one printing press can complete the production process from data to printed materials, which saves equipment , Time, materials, and reduced production costs. 1. Special printing machine The main representative model of the dedicated plate printing machine is TruePress. Its basic structure is a four-color printing machine with a double-diameter cylinder structure, equipped with Mitsubishi Silver DigiPlate direct plate-making and developing equipment to form a composite structure printing machine . Because the Mitsubishi Silver Digi Plate is used as a direct plate-making plate material, the cost is low, and printing inks with various properties can be selected according to different needs. Therefore, the use conditions of this printing machine are closer to those of traditional printing. And this plate material can use UV ink to solve a series of problems caused by the long drying time of ink in the previous printing. 2. Traditional printing machine The main representative model of the traditional printing press is Heidelberg SpeedMaster Dl74. This model is based on the traditional printing machine SpeedMaster 74. Therefore, the PS plate or direct plate-making can be used to make plates with a resolution of 2400dpi. The plate material is PEARLgold from PressTek and the same type of plate material. The above-mentioned digital printing machines all receive layout information in the form of numbers for printing. Therefore, how to correctly transmit data from the network or database to the printing machine is a critical issue. In the entire process of data transmission, the bottleneck must be identified first in order to improve production efficiency. In the future, it is necessary to carry out research in the following aspects: 1. Digitization of the entire layout of the printed matter; Anti Climb Fence Top,Anti Climb Temporary Fencing,Anti Climb Fence,Hot Dipped Galvanized 358 Fence Hebei Giant Metal Technology Co., Ltd. , https://www.358fencing.com
2. Digitization of analog film;
3. Electronic collation and electronic binding;
4. Speed ​​up the calculation time;
5. Data processing compatible with the amount of data;
6. Layout data preservation;
7. The use of databases.
