What equipment is generally used for advertising printing?

Printing: Generally, it is a printer, photo machine, inkjet printer and other output devices that can be connected to a computer. From the working principle, it can be divided into dot matrix, inkjet, and laser. There are certain requirements for the corresponding paper. The higher the accuracy and color, the paper must be relatively smoother, better, and even have a special coating. Therefore, the price per sheet is relatively high, the size is also small, and international standard drawings or photo paper sizes are usually used. Photos and inkjet printing use special synthetic paper, which is similar to adhesive tape and is divided into several layers. The size is relatively large and corresponds to the relative size according to the width of the equipment. The small ones have a width of about 90CM, and the large ones are 1.2M, 1.5M, 3M or even larger. Large ones. For example, outdoor light boxes or giant wall advertisements are made of multiple pictures spliced ??together. The unit price is 10-50 yuan/square (the regular price varies from place to place). Generally, desktop printers are inkjet or laser. Mostly, the paper can also be selected according to the printer and image requirements. The retail price of ordinary A4 is 25-40/pack/500 sheets/80g. The price of thicker and smoother paper is higher. Photo paper is generally 20 or 25 sheets/pack, and the price is also Around 40, (reference price, region and brand are all affected). In addition, the printing cost is also affected by ink and toner. Toner is relatively cheap, but it cannot print in color. Laser printers usually use toner. Generally speaking, the printing method is: simple and flexible, easy to operate, and fast. Disadvantages: small size, high unit price, and slow mass production speed. Printing: The principle is different from that of printing. It generally requires typesetting, color separation, film output (film), plate making, On-machine printing. Common printed materials must be designed in a computer and then undergo color separation processing, which means separating the colors of graphics and text into 1, 2, 4, or 6 colors according to the performance of the printing machine. In addition to single-color printing, 4-color or 6-color printing is common, which means that the colors in the picture and text are divided into 4 or 6 separate pictures of the same field according to the hue. For example, "CMYK" is a common four-color printing, (cyan, magenta, Magenta, **Yellow. And K is the last letter of black, black), and then these colors are output to special printing films. (film); make a special plate, and use printing equipment to superimpose or overprint several colors onto the paper. The efficiency of printing machines also varies greatly in price. The price of a single-color printing machine is around 5,000-10,000, while a 4-color and 6-color printing machine often costs tens or hundreds of thousands. This is because of machine performance, brand, operation difficulty, and maintenance. There's a lot of variation, so there's a lot of variety in price. Printing method: suitable for mass printing, high precision, good effect, rich sizes, many final forms (various packaging boxes, books), the more mass production, the lower the unit price. Disadvantages: complicated process, high technical difficulty, many auxiliary materials (film and ink and other auxiliary materials will affect the final effect), the equipment is huge, and machine maintenance is complicated;
