.Use Method︰
* Diazo mixture:
Diazo dissolution is about 10% of total weight of emulsion of water soluble until completely dissolved, mixed with emulsions. (Diazo dissolution can not use hot water. In addition, the container can not be used diazo dissolved metal containers.)
Diazo solution and the emulsion to stir, to prevent bubbles, stir placed a day or more with 250 mesh screen filter before use. Diazo added after dark in the cold preservation, use about 10 days.
* Coating:
Sensitive adhesive coating prior to wire-line to confirm that no dust.
KC Series with a bucket scraping coating, etc., with hand-painted or automatic coating machine coating, coating to prevent air bubbles entering the time.
* Dry:
Drying temperature below 40 ℃ for. (Drying temperature is too high, can lead to heat curing.) Using the KC-SM-DC series bake edition boxes of dried.
* Exposure:
Using the KC-SM-UVE Series Shai Banji to copy, please refer to the emulsion exposure time exposure time of the page
* Developing:
Developing available water. All development of water wetting. Developing the use of pressurized water (spray gun, automatic developing machine, etc.) the most suitable.
In addition, the development has been soaked in water prior to curing some easy expansion off, affecting image quality.

Usage︰
In the process tighten silk, before coating the adhearing emlmusion between the silk and screen frame, Tensionmeter used to measure the tension of screen plat in order to get Precision Data.
Technical Parameter︰
Measure range: 0-35N/cm;
Telerance: 0.05N/cm
Use Method︰
1. After Tighten silk onto screen frame and before coating adhering Emulsion Glue;
2. Take a Tensionmeter and put it onto the five point of screen plate, measue the tension range;
3. If you find the tension is not come up to the requirment data, Please continue tighten the silk .
4. Store in drying and far from magnetic feild.
Coating tool
* Make sure All logo included in the coating section with the coater; more wider logo need more wider coater;
* Please make sure teh coater clean;
* This coater suitable for making small size screen plate, and suitable for making large size but lower quality screen plate.
Usage︰
With the coater, you will coat screen emulsion onto the surface of screen silk, This is important step of making screen plate.
Technical Parameter︰
Production Advantage ︰
Use Method︰
* Please choose the coater which width is a few than Width of logo on screen plate;
* Pour Emulsion with photosensitizer into the coater;
* Close the coater to the surface of screen and coating emulsion Evenly.
