Description
Technical Field
The invention relates to the technical field of functional polymer films and preparation methods thereof, in particular to offset printing touch oil and a preparation method thereof
Background
The touch film is also called a soft film, and is a special matte film for lamination, the surface of which has special velvet with smooth and fine touch. The touch oil is coated on the surface of the film, so that the touch oil can be used for luxury packaging, high-grade books and periodicals packaging, high-grade hangtag and the like, and has the advantages of friction resistance, no fingerprint mark, velvet hand feeling and the like. However, when the touch film is used for high-temperature and high-pressure thermal bonding, the surface touch is completely or partially lost under the action of temperature and pressure, so that the application of the touch film is limited.
Offset printing is a type of lithographic printing, and is simply called offset printing, which is a printing mode in which images and texts on a printing plate are transferred to a printing stock by means of a rubber blanket, and is called a printing mode in which the existence of the rubber blanket is the same. The blanket plays an irreplaceable role in printing, such as: the printing ink can well make up the unevenness of the surface of a printing material, fully transfer the printing ink, reduce the transfer of water on a printing plate (after the water plays a role in printing) to the printing material, and the like. The above is also merely a general concept, and we now refer to offset printing in general to a narrower range, namely a lithographic printing method with three cylinders (plate, blanket, impression), which is called koku printing in the south of our country.
The conventional touch oil cannot be used on an offset press because of problems such as leveling, drying and the like.
