Screen Cut Green film has been developed to speed up stencil making and allow less equipped print rooms be able to make their own stencils. With this film, stencil making doesn’t need a dark room, any special lighting conditions or a UV lamp, print down frame etc. It also does away with the need to generate a positive film.
Screen Cut Green Film is a hand cut or machine cut stencil film, that adheres directly to the mesh. Screen printing stencils made from this film are suitable for either water based or plastisol inks.
The film is transparent so when placed over an image, hand cutting the image is made easier. The film can also be cut on a plotter or vinyl cutting machine. When you have cut your image weeding is easy. Weeding is the removal of the film in the printable areas. The film is then placed on a soft pad and a degreased silk screen frame placed over it. You then brush a minimal amount of the application fluid over the mesh. You will see the film instantly darken as the capillary action takes place. If you have light areas just reapply a small amount of the application fluid to the area so the colour is even all over the stencil film. Then leave to dry and peel backing film from mesh. The screen is now ready to print. . The green stencil film can be removed from screen after printing using our AQ 1008 Screen Mesh Cleaner.
Aquarius Blue Filler is a solvent resistant flexible and cost effective mesh filler. The blue filler is water based and is environmentally friendly. Applications include spotting out, filling gaps between the frame and stencil. The filler can be removed with water and is resistant to all plastisol and solvent based inks. It can be applied by brushing or scraping. This product is non-hazardous.
Our Post Hardener is a ready to use acidic solution, when applied to an exposed photographic stencil will increase the mechanical, water and solvent resistance. Ideal for screens that are used for long runs or are to be kept permanently. Once applied to the stencil, it may be difficult or impossible to reclaim the screen.
This simple piece of plastic can help all screen printers obtain the correct exposure for all their mesh counts and stencil thicknesses. To use the calculator correctly you should coat the screen with the same number of coats you normally use.* This is very important as you must have a consistent coating thickness so all tests use the same coating criteria. If you expose for 2 minutes then when you conduct the test you would double the exposure time to 4 minutes(with an integrator you would double the units used for the exposure). You place the Exposure Calculator in the same position as you would your normal positive. When the screen is exposed, washout in the normal way. You now need to dry the screen. The stencil should now display various shades. Start from the lightest section working towards the section that has no colour change. The first section with no colour change is the correct exposure. You then multiply by the factor on that section the time or units you exposed for. If all sections show a colour change then you have under exposed the screen. You will need to double the exposure time and repeat the test.
*N.B. if you use different thickness of stencils for different jobs you should conduct the test separately for each one.
