Postoji nekoliko ključnih faktora u procesu sitotiska sive boce šampona
1. The first is the pretreatment of plastic containers quality bottles. The surface tension of the bottle is directly related to the problem of ink firmness after printing. Generally, the surface tension of the material needs to reach 50dyn/cm, and the ink firmness after printing is more guaranteed. Products with strong material polarity can be directly printed. Although PET material bottles are of weak polarity, with the selection of appropriate inks, PET bottles can basically be printed directly without surface treatment. For bottles of non-polar materials such as PP and PE, the surface of the bottle must be treated. The general treatment method is flame treatment or corona treatment. A simple way to judge is to observe whether the surface of the bottle on the dyne droplet can be spread out, that is, it can be "hanging on water" to indicate that the surface treatment effect meets the requirements.
2. Drugi je kvalitet sito štampe u setu plastičnih kontejnera. Otpornost na habanje, broj mreže, napetost i debljina fotoosjetljivog ljepila materijala za sito imaju veliki utjecaj na kvalitetu sitoštampe, debljinu boje, očvršćavanje boje i vijek trajanja.
3. Again, it is the choice of mini plastic container ink. Different inks have different adhesion to the surface of bottles of different materials, and different color inks have different energy requirements for curing. Therefore, to ensure the fastness of the ink, it is necessary to select the appropriate ink for the substrate of the bottle. If you still can't meet the requirements, you can try adding an appropriate amount of auxiliary solvents such as a curing agent to the ink.
4. Posljednja je prazna plastična posuda UV lampa. UV lampe su ključna oprema za očvršćavanje mastila. Različite kompozicije mastila, boje i debljine zahtevaju različitu energiju za očvršćavanje. Sa različitim oblastima štampanja, izbor specifikacija UV lampe je takođe različit. Stoga je razuman izbor UV lampi takođe ključ za potpuno osiguranje postojanosti mastila. Da li UV lampa ispunjava zahtjeve može se procijeniti ispitivanjem učinka uzorka. Nakon određenog perioda upotrebe potrebno je provjeriti i provjeriti da li UV lampa stari. Ukoliko ne ispunjava uslove, potrebno ju je zamijeniti novom UV lampom.
