SQUEEGEE BLADE

White rubber is perfectly serviceable for most print jobs in the Art room, especially fabric printing. The disadvantages are that rubber deteriorates. It loses its printing "edge" quickly and is attacked by strong solvents.
Polyurethane, on the other hand, is tough, keeps a good "edge" for 1000s prints and is not adversely affected by strong solvents. It is particularly suited for high quality "Fine Art" prints. 'D' Cut (V-Section) is designed specifically for fabric printing. It ensures a good ink deposit and retains definition.

MESH PREP GEL (MESH PREPARATION)

Screens which are stretched with Monofilament Bolting Cloth will require degreasing before emulsions, fillers or films can be applied to them. The reason for this is that the surface of the thread is so smooth that minute traces of grease (even grease from your hands) will create problems with adhesion and cause premature breakdown of the stencil.
The GEL is non-corrosive, safe to handle and easy to use. Simply wet the mesh and using a soft-bristled washing-up brush loaded with the GEL lightly scrub both sides of the mesh. Leave 2 minutes then rinse thoroughly and allow the screen to dry. Use rubber gloves to protect your hands.

SELECTASINE WATER RESISTANT DIAZO EMULSION

Fully water-resistant diazo sensitized emulsion. The whole container may be sensitized before use as the shelf-life is in excess of 3 months if stored in cool dry conditions. Coated screens may be stored in cool, dry, dark conditions for up to 2 weeks.

PHOTO EMULSIONS GENERAL METHOD

1. Prepare screen by degreasing mesh with MESH PREP GEL and allow to dry.
   
2. Sensitize the emulsion.
   
3. Coat the screen evenly using a coating trough, 3 coats each side, "wet-on-wet" starting with 3 coats on the underside. Don't over-apply the emulsion. If the coating is too heavy remove the surplus by running the dry blade of the coating trough up both sides of the screen.
   
4. Dry in horizontal/printing position with the frame propped up and in the dark or darkroom conditions. Drying can be assisted using a fan provided dust is not blown around or heat spots are generated. (Emulsions are sensitive to light and heat).
   
5. Place film positive (Photomask) in close contact with mesh and expose to ultra-violet light.
   
6. Use cold water spray to wash out screen until image area is clear.
   
7. Swab off excess water using Newsprint and/or chamois leather and dry screen

• Stencils can be removed using Stencil Remover Concentrate Fluid.

STENCIL REMOVER CONCENTRATE

Add 1 measure of stencil remover concentrate to 20 measures of water. Wet both sides of the screen with this liquid and scrub with a soft-bristled nylon brush. Leave for a maximum of two minutes, then wash away with a strong jet of water.
Use rubber gloves to protect hands and eye protection.
