Comparation with other models
Strengthening the effect of pulling tension , especially in PET film , better performance on glossness , pulling tension and adhesion since its higher solid content .
Please see the below compare table :
We keep 24 hours after lamination process .
Glossness : Based on 60°angles , better performance if figures is higher.
Pulling tension : Generally to speak , stronger pulling tension is a good sign for judging if adhesion is good or not , but it’s not always correct , another better way to judge adhesion is to check if pass “Die cutting” process.
Adhesion : To judging if paper and pp film are sticking together or not , tighter performance is better .

General questions for Water based resin
Q1: Why we can find the “White point” on surface ?
A: There are too many factors have lead to fail mirror surface , such as the paper too rough , varnish too thin , varnishing speed too high, too many powders when it printing , roller’s rubber too old to use…etc.
Solution: Please build the varnish up , slow down the speed and change the new rubber for operate more smoothly.
Q2 : Why not gloss after varnishing ?
A: Please raise up the temperature for iron board (more than 100 degree ) and pressure more than 125KG/CM2 , add up more varnish or change iron board for improving.
Q3: Blocking paper
A: Please keep down the temperature and slow down the varnishing speed to improve volatility too fast.
Q4: Why Ink spread out after varnishing ?
A: You can varnishing after confirm the ink already dry , change the solvent or keep down the pressure of varnishing machine.
