Some methods of using uv offset printing inks

UV series ink is [Shanghai UV offset ink [/ url] the introduction of the latest foreign high-quality raw materials, using a unique formula of technological innovation, for the production of a variety of bank cards, telecommunications cards and other card types of special UV offset ink, can completely solve the domestic The following problems often occur in the printing industry when printing cards with ordinary inks:

1. When the card is laminated, the ink or varnish sticks the steel plate;

2. Discoloration of ink color when laminated at high temperature;

3, after the film card, the ink peel strength is too low;

4, ink does not adapt to the process of card printing, coding and other processes.

Shanghai UV offset ink [/ url] can fully meet the processing requirements of printed cards, and has unique advantages in high-speed printing, high adhesion performance, and complex molding processing.

First, product characteristics

1, high temperature resistance: high temperature, no discoloration

2, peel strength: high peel strength, up to 5N/cm2 or more.

3, laminating: good lamination, non-stick steel

4. Flexibility: The ink film has good flexibility after curing, and the ink film is not easy to break after grinding

5, odor: less odor, apply to products that have a higher demand for odor.

6. Adhesion: It has excellent adhesion performance and is suitable for the printing of non-absorbent materials such as PVC, ABS, PET, OPP.

7, process adaptability: the network is clear, the cured film can be suitable for thermal transfer code, hot stamping code and code.

Use caution

1. About Plate

Offset Printing: You can use the negative PS plate directly or the positive PS plate for UV inks. If you use an ordinary positive PS plate, you must use a baking plate.

Resin Relief: Use nylon-based resin relief.

2. Cots: It is recommended to use UV special roller or ordinary offset ink and UV ink dual roller

3. Blanket: Common offset ink, UV ink blanket can be used

4. Fountain solution: The fountain solution sold on the market can generally be used, but the curtain paste containing a large amount of gum arabic can not be used.

5. Cleaning fluid

Cleaning version: UV plate cleaner

Cleaning roller: UV818 cleaning agent

6. Ink Additives and Use Limits

Varnish UVJ-1000 0%-5%, reduce ink viscosity, increase ink flow performance

Light remover UVJ-2000 0%-100%, reduce the color intensity of UV offset ink; little change in ink viscosity and other rheological properties, printing performance. It has a slight effect on the fluidity, gloss, consistency, etc. of the ink.

Viscosity reducer UVJ-8000 0%-20%, reduce the viscosity of the ink while maintaining the ink elasticity

7. Preservation conditions: Closed storage in a cool, dry room, avoid room temperature above 30 °C or direct sunlight.

8. Regarding the adhesion performance: The adhesion varies depending on the type of substrate. Therefore, the adhesion of the ink should be checked with a tape before the printing is officially started, and the corresponding UV ink should be selected.

9. On the post-processing performance: sometimes after printing ink need to be gluing, laminating, bronzing and other post-processing, this time must choose the appropriate glue, film and bronzing materials. And after the test, it is better to officially print.

10. In the safety performance: Please do not stick the ink on clothes or skin for a long time, and sometimes it will cause allergies. Therefore, please pay attention to protection during use, and clean it after use.
