Products For Screen Preparation

Basic Principles Of Screen Preparation

Screen cleaning and preparation can be divided into four steps. In the case of a new mesh you would only need the final stage, mesh degreasing. The following steps should produce a mesh that is free of any contaminates and ready for the reapplication of your stencil medium. When you have finished your print run you should always clean all ink from the mesh and wash with the appropriate cleaner. This will help prevent ghost images in the future. When you are ready to reclaim mesh and remove the stencil, follow the steps below.

Use Of High Pressure Washer And Screen Rinsing

Always rinse before high pressure washing the screen. The reason for the rinse phase, it helps prevent any of the stencil and cleaning products getting airborne when you use the high pressure washer. When using the high pressure washer always start at the bottom of the mesh, work the jet across the mesh then up and across again. Working the washer head across and up the mesh is the most effective way of removing stains. Then repeat the process on the other side of the screen starting at the bottom as before.

Step 1

Ink Cleaning

Step One should always be carried out when you stop printing. Scrape all wet ink from frame. If appropriate, add ink to original container else dispose of ink in waste container. Now wash ink from screen using the recommended cleaner. Place screen on absorbent paper. Wash screen with rag on the squeegee side. Be very careful when cleaning substrate side of the screen as this can be very delicate and easy to damage stencil.

Step 2

Stencil Removal

We have two stencil stripping products. Strip n Clean is a liquid concentrate and can be diluted with water, it can also be used in a dip tank. The PhotoSolve Gel is used straight from the pot. This is the method for using PhotoSolve Gel to remove stencils from the screen mesh. Remove all blocking tape from screen. The Gel is applied using either brush or pad onto both sides of the cleaned screen. The gel needs to be agitated on the screen, this will help it penetrate the old stencil medium. The gel should never be allowed to dry, this will make stencil reclaim more difficult. After five to ten minutes agitate the old stencil and then rinse. Now blast with a high pressure washer to remove old image from the mesh. If any old stencil material remains repeat above procedure. The advantage of the gel is its ability to remain on the mesh dissolving the old stencil medium without running to the bottom of the frame.

Just before coating or applying a stencil film to the screen it should be degreased. This step will remove any dust or finger prints. Apply the degrease gel to both sides of the screen with pad or brush. Then gently rinse the screen starting at the top of the frame and working down, make certain the frame its self is washed so no drips contaminate the mesh then repeat rinsing on other side of mesh. Then vacuum mesh to remove excess water. The screen is ready for its new stencil when completely dry.
