The printing plate of corrugated paper box, the flexible version is the first choice. Flexo printing has advantages that are unmatched by other types of printing methods and has outstanding environmental protection features. However, these advantages and features must be reflected in the product, and high-quality products must be printed before users can recognize and accept them, and flexo printing will develop. Therefore, how to purchase and use flexo is a problem faced by each carton factory. The carton factory's demand for flexographic printing plates is divided into two types. One is to entrust the outside of the factory to make a complete version; the other is that there are plate-making equipment in the factory to make the plates by themselves. Thing? The flexographic printing plate for carton pre-printing is thin, with a thickness ranging from 1.7mm to 2.84mm, and a hardness of about 50o on the Xiao A level. It is not widely used in China at present, and is rarely used by factories. The flexographic printing plate used for post-carton printing is thicker, with a thickness ranging from 3.94mm to 7.00mm, and a hardness of about 30o to 45o of Xiao A grade. It is currently used by most carton manufacturers, of which the thickness of 3.94mm is the mainstream. For plate materials, proper storage and management is very important. The following is a brief introduction to the storage and management of flexo plates during plate making, the whole box of plates and the finished plates. 1. When making plates in the factory, the basic processing rules for plate storage are as follows: 1. Unexposed plates 2. Plates exposed: 3. Wet plate after washing 4. Plate after drying 2. The whole box of plate materials from the plate material supplier is stored as follows in order to maintain the best condition: ◆ Temperature control: 5 ℃ ～ 25 ℃, when the temperature is lower than 10 ℃, the plate material transferred to the plate making room should be placed stably for a period of time to avoid the thermal shock effect on the exposure machine 3. The storage requirements for finished plate materials from plate makers are as follows: ◆ Pure air: good ventilation, no dust, no solvent volatile gas, far away from ozone source Taihe Fangyuan Muye Co.,Ltd , https://www.fangyuanfurniture.com
â—† Placed in the packing box, wrapped with black plastic film
â—† Cannot be placed on uneven contact surface
â—† Before the film is exposed, the surface flakes can be peeled off
â—† After peeling, excessive bending will cause the protective layer to wrinkle, and these wrinkles will leave stains after exposure to plate making
â—† Handle with care, with a piece of cardboard underneath to prevent bending
â—† Lightly cover the original surface sheet to protect
â—† Avoid contact with the resin surface, otherwise it will form stains
â—† When processing, avoid inhalation of the volatile gas of the solvent
â—† Place on a flat contact surface to allow it to cool
â—† Do not touch the resin layer
â—† Prevent sunlight or other ultraviolet light
â—† Humidity control to avoid excessive humidity (within 60% humidity)
â—† Packing box placement method: all flat, no more than 10 boxes per pile
◆ Temperature control: 5 ℃ ～ 35 ℃
â—† No light exposure: dark room
â—† Do not contact the plates: there is sufficient air circulation between the plates
