It is generally recommended to stick crystal labels on hard and smooth materials such as packaging boxes, tea cans, paper cups, notebooks, iron cans, aluminum boxes, plastic, stainless steel, ceramics, etc;
Precautions for crystal label UV printing
When we are printing crystal labels with UV, you must pay attention to these matters:
01 Glue Selection Special Glue:
The adhesive for printing crystal labels requires specialized adhesive, which must meet the requirements of firm adhesion, not easy to fall off, waterproof and sun proof, wear-resistant and scratch resistant.
The selection of 02 ink UV ink determines its quality:
You need to choose ink that has high hardness, good adhesion, abrasion resistance, solvent resistance, and high glossiness after curing.
You need to choose ink that has high hardness, good adhesion, abrasion resistance, solvent resistance, and high glossiness after curing.
Durable white ink determines its three-dimensional design: you need to choose white ink that is not clogging the nozzle, smooth, and brightly colored.
▲ Application scenarios for crystal label UV printing
03 Gloss
The choice of varnish determines its firmness: you need to choose a varnish with fast curing speed, good adhesion, and high brightness and brightness.
04 base paper
The choice of base paper determines the transfer effect: the choice of base paper determines whether the crystal pen can transfer completely and easily.
So when tearing off the A or B film, be careful not to pull at 90 degrees. Try to tear the film horizontally at 15 degrees to prevent wrinkles or deformation, which may affect the label effect.
■ 05 Application: Avoid high temperature conditions or sticking to rough surfaces:
The situation where crystal labels will melt when exposed to high temperatures makes them unsuitable for applications such as high-temperature baking or long-term boiling water.
However, for items with a rough surface, the dispersion of their contact points can affect the adhesion of the crystal label.
