Plate is divided into the following: hand-engraved version, laser engraving, sun-made flexo, made soft film lithography (PS version), die-cutting version. The above-mentioned plate making technology is often used in carton enterprises. According to the size of the enterprise, the use of plate-making technology is not the same. Small carton factory is the use of manual engraving process technology, this technology is low cost, but the requirements of the engraved staff is relatively high. Now, this plate-making technology is relatively small, but in some small carton factory in the Midwest is still relatively common.
Laser engraving flexible version (rubber version): Some carton manufacturers in order to reduce production costs, some small batch of scattered orders for the majority of the use of laser plate making technology for the production of the plate-making technology in the country more than medium-sized carton production enterprises Are more common. This plate-making method is more convenient, the need for a computer and a laser engraving machine, in the plate, will use a computer designed a good layout through a plate-making way.
The specific operation is: the engraving staff will be the layout of the layout according to the layout of the layout, the base plate as required in the laser engraving machine, and according to the requirements of positioning, computer output engraving instructions, laser engraving machine carving, After engraving, laser engraving machine prompts, engraving personnel need to continue to carve, you only need to follow the above procedures to replace the base plate after the operation can be. After the engraving, the plate-making staff need to clean up the layout, will not need to remove the part, and then by the plate-making staff to control the sample to do a good job to review the layout, to confirm the correct delivery unit to use or make hanging version. Such as the production of hanging version, you need to make a version of the plate after a good copy of the layout of the review again, and then submitted to the production sector. Otherwise, shall not be put into production use.
Laser die-cutting: under normal circumstances by the professional plate-making company to do. This plate-making approach is the advantages of plate-making speed, high accuracy, relatively durable. The disadvantage is that the tooling speed is slow and the cost is high. Under normal circumstances, to do this version is made by the carton enterprises according to the specifications of the carton specifications to make layout design, through the network transmission to the professional plate-making company, a professional plate-making company according to the pattern of production, and then back to the carton business, Personnel audit after the use of the production sector. There is also a way to produce die-cutting version, that is, hand-made, drawn through the computer drawings, hand-cutting version. Manually enlarge the drawings on the base plate, the use of professional equipment for drilling, sawing, hand-knife and steel wire, after the completion of the audit to confirm, you can use the post-production sector to use. However, this plate-making method of low efficiency, not durable, easy to error. Now, very few companies use hand-made plate.
Drying flexible version (resin version): through the computer design a good layout, play clear the delivery of paper boxes to confirm the procurement of enterprises after the plate. Through the sulfuric acid paper or film film to do the film, the resin base plate size according to the size requirements cut, the film covered in the resin substrate, surrounded by light-resistant cover to prevent excessive exposure, the normal use of the layout The After all ready, the base plate on the dedicated copy machine for exposure, exposure time about 30 minutes or so, after the completion of the version removed, into a professional washing machine for cleaning. After the cleaning is completed, then put into the baking box for baking stereotypes. After the stereotypes need to be sticky treatment. After all this is done, it is up to the professional designer to review the layout, and then use it.
Drying plate (PS version): through the professional design plate company design and proofing. This proofing is the color proofing to facilitate the carton printing enterprises in the printing and proofing ink to keep in line, especially multi-color printing, dot printing, in the network, color control should pay attention to. Plate-making staff in doing the printing plate in particular, pay attention to the exposure time to master and exposure equipment cleaning. In the plate-making staff for drying plate, the first to clean up the copy machine to keep the exposure surface clean, open the device and start, take a meet the requirements of the base plate in the middle of the plane. Press the press and the rules of the rules to stay good positioning line, the film (film) according to the location of the positioning line put, flat on the flat version above. Close the Shai Banji and start the vacuum machine, set the exposure time, start the exposure device, according to the set exposure time exposure (under normal circumstances set time between 20 seconds to 2 minutes, the specific length of time set by the plate Personnel according to the needs of the sun plate set). When finished, let the exposure device automatically cool and close, open the Shai Banji, remove the film put away, remove the plate placed in the developer for automatic development. The development is completed, rinse the layout with water, plate-making staff to dress the layout, remove the dirty points, dirty lines, etc., to facilitate the printing, so that the layout clean, completed after the production sector to use.
Above is the author combined with personal cartons in the production of some practical experience, with reference to the current domestic large and medium-sized carton production enterprises in the practice of a summary. In the specific operation or according to the actual situation of the enterprise, the use of plate-making equipment to do the specific situation, do not blindly mechanically. Now the design of plate-making technology can be said that with each passing day, especially in some of the domestic design of plate-making enterprises in the design and plate-making areas to do a considerable aspect of the outstanding, become the design plate industry leader. However, as a carton production enterprises in the design of the plate must be based on the actual needs of their own business to do, and not greedy for the whole. Of course, some large and large carton manufacturers in order to meet the requirements of customers faster to improve the efficiency of the design, the introduction of professional proofing equipment is possible, usually or by professional companies to do, this cost is more suitable for enterprises development of.
