WORKING INSTRUCTIONS & SAFE HANDLING

Sensitising of Emulsion

Note:  New ‘direct addition’ of Diazo

Handle PLUS 2000 under yellow fluorescent tubes or low wattage Tungsten light.  PLUS 2000 is supplied as a two pack kit comprising the emulsion and powder sensitiser in a sachet.

  1. Prior to sensitising read the Safety Data Sheet.  Mix the two components as follows:
  2. Cut the powder diazo sachet open using a pair of scissors (DO NOT OPEN WITH TEETH).
  3. Add the powder diazo sensitiser DIRECTLY to the emulsion.(DO NOT DISSOLVE THE SENSITISER IN WATER OR ADD ADDITIONAL WATER TO THE EMULSION).
  4. Stir thoroughly for approximately 2-3 minutes to ensure emulsion is sensitised throughout. Allow the emulsion to de-gas for 15 minutes before use.

Coating & Drying

Stand the screen on edge, angled away from the operator and, using a good quality coating trough, proceed as follows:

  1. Apply 2 coats to the print of the screen.
  2. Apply 2 coats to squeegee side.
  3. The screen should be dried horizontally, squeegee side up and stored under dark or yellow light conditions.  Dry the screen at a maximum temperature of 30°C (86°F).
  4. Additional coatings may be applied to the underside of the screen with intermediate drying.

Exposure

CORRECT EXPOSURE IS ESSENTIAL FOR OPTIMUM STENCIL PERFORMANCE.  UNDEREXPOSURE WILL GIVE A WEAK STENCIL AND REDUCE RESISTANCE.

Remove dust from the surface of the stencil and tape positive in position.  Place entire screen in a suitable vacuum frame and expose.  We recommend use of the Autotype Exposure Calculator for test exposures to ascertain correct timing.  Exposure times below should be used as a guide:-

Washout & Drying

Wash out the screen from both sides with a strong spray of water.  Continue the washout until all parts of the image appear clean and sharp.  Blot off surplus moisture with newsprint or a leather and dry at a maximum temperature of 30°C (86°F).

Spot out blemishes with sensitised emulsion.

Stencil Removal

Remove ink from the screen, with Autosolve screen cleaner.  Apply Autostrip to both sides of the screen.  Leave standing for 5 minutes.  The stencil can then be removed with a strong water jet or high pressure stripper.  If a stain or ghost image still remains, use Autokleen Plus.
