The difference between the plastic printing and paper printing? The difference between the plastic printing and paper printing?

the different printing process will lead to the different effects, depending on the printing plate ink quality, quality of ink scraper, wow we may seal printing quality. The following focuses on understanding the difference between the plastic printing and paper printing, in order to better understand printing, know how to choose and buy.

one, the basic principle of plastic printing and paper printing is the same

1, the color of the original art decoration design, plate-making equipment and plate-making technology are basically the same.

2, the structure of the printing press, embossing and printing principle are the same. Multi-color gravure rotary press and multi-color flexo rotary printing press can be used for printing plastic film, and can be used for printing paper.

3, the principle of color and the application in printing are basically the same.

the difference between the two, plastic printing and paper printing

1, printing substrate different one kind is plastic film, the other is a paper, their physical and chemical performance is quite different. Paper surface has a certain roughness, and a good state of adsorption and capillary effect, printing ink on paper adhesion easily. Paper before printing in an indoor spread out level off for a period of time as long as the drying paper put static eliminator and the printing press and eliminate static electricity can be used for printing. The plastic film is different, as in the packaging on the dosage of polyethylene and polypropylene film, most high surface finish, low surface tension, chemical stability strong, not easy to accept ink infiltrate, combined with the plastic itself has the oxygen resistance, these will affect the plastic printing after drying, ink layer and uf membrane.

2, printing ink can't interoperability

for printing paper and plastic printing due to the nature of substrates, printing ink and ink drying way link of material is different. So the printing paper printing ink can not be used for printing plastic film, otherwise can't dry conjunctiva, prone to separation, qualitative change, such as fault, causing unnecessary economic losses.
