2. Characteristics

3. Features

3.1 Smooth film.

3.2 High printing speed.

3.3 High pattern resolution. 

3.4 Ultra-high sensitivity.

4. Exposure Time

Second exposure after development can improve the printing life.

5. Usage

Mesh preparation 

Using DENBISHI degreaser to clean the mesh before coating. And then keep the screen cleaned and completely dry. 

photo emulsion preparation

Mix Diazo with 100g water and stir for 3-5 minutes. And then put the mixed water in emulsion and stiring again 3-5 minutes. Completely using the mixed emulsion within 8-12 hours.

Coating：

Please use high quality scraper. Coating properties closely related to the size and tension of the mask. The printed materials affect coating times and the film thickness very much.For two more coating, please coat again when the former coating dry completely in case the film falls off. The drying temperature must be controlled below 40°C. The higher temperature will produce thermal reaction and affect the plate-making effects.

Exposure: 

Ajusting CTS machine and exposure the emulsion.

Development: Please use water cannon and spray gun flush the mask uniformly.

Dry：Remove the mask surface’s moisture after development. Then dry it in the dry oven under 40°C. The mask should be dried completely otherwise the glue will fall.

6. Precautions

Storage of Emulsion: 

Store the emulsion (without diazo) in dark place at 20°C and do not store it at more than 25℃ or lower the 5℃. Storing Diazo in refrigerator at 0-5℃. 

Screen Degreasing：

Please use professional screen degreaser to wash the mask and remove oil and dust before coating.

Diazo Dissolution：

Use pure water to dissolve diazo rather than tap water, because the mineral substanc and water rust in it can react with emulsion and affect the emulsion’s performance. What is the worst is the paste will clotting and the emulsion can not be used.

Temperature of the oven: 

Control the oven temperature below 40°C .The resolution will decrease if more than 40°C. The dry oven should have exhaust device so that the moisture can be discharged and the dry efficiency can be improved. Check monthly weather inside temperature is consistent with the setting temperature.

Development in Winter: 

Use warm water (25°C) to develop. The low temperature water  in winter may cause bad development and decreasing of resolution.
