Ultraviolet (UV) curable highlight ink

As an excellent packaging material, polyalkylene-based plastics have been widely used in the packaging of daily chemical, pharmaceutical, chemical and food products. The resulting printing ink market is also expanding. Since UV-curable inks have excellent properties that cannot be replaced by other solvent-based inks, they are being used more and more widely. Most of the commonly used inks on the market today are inks made in Japan or in France. Due to the high price and the delivery time, many bottle manufacturers in the country are in trouble. Henderson Ink Coatings (Hangzhou) Co., Ltd. has been working closely with internationally renowned UCB and SADOMA companies since 2001. Through nearly three years of hard work, in May 2003, the company officially launched special printing on PP, PE, PC and PVC materials. Bottle "UV-PPE ink".
This product is UV-curable high gloss ink and can be printed on PC, PVC, processed PP, PE bottles, sheets, and other products through the screen printing process. Such as shampoo bottles, shower gel bottles, paint buckets, cups, boxes and other goods. After UV curing, it has clear and sharp printing effect and excellent chemical and physical resistance.
A brief description of the product's instructions for use and related technical parameters is given below:

Explanation: 1. The above colors are all environmentally friendly non-toxic inks. The lead content index has reached European EN-71 standard and Japanese ST standard.
Fourth, operation suggestions:
1. Ambient temperature control: UV-PVC inks have great influence on the change of the viscosity caused by the ambient temperature. If the temperature is too low, the viscosity of the ink will become very large, causing the ink to penetrate the screen. Poor, and there may be problems with air bubbles or poor leveling. Therefore, the printing shop should try to keep the room temperature constant, generally 20-28 degrees, to ensure the consistency of the printing quality.
2, screen: generally 350-420 mesh / inch is appropriate, should be used S-class screen, the thickness of the photosensitive adhesive to 10u below is appropriate.
3. Scraper: Use a polyurethane scraper with a hardness of 75-80 degrees. The blade is sharp.
4. Viscosity adjustment: Before use, stir it evenly. According to the printing requirements, if you need to reduce the viscosity, add 5% or less of UV-156 diluted Varnish and mix it before use.
5. During printing, care should be taken to avoid direct exposure to ultraviolet light and sunlight in order to avoid accidental curing of the ink. Yellow light is safe light.
6, PP and PE materials should be flame treated before printing. Increase the surface tension of the material to 38 dyne/cm or more. If not handled properly, it will affect the ink adhesion.
7. When printing multi-layer superimposed colors, we should pay attention to weakening the intensity of the pre-colored UV light to avoid the phenomenon of poor post-color superposition due to over-curing of the preceding color.
