MacDermid Autotype PLUS 7000 screen printing emulsion produces a high quality print that is preferable for surfaces which require durability, print quality, and easy removal after printing. MacDermid Autotype PLUS 7000 is water resistant, meaning that it can be used in areas with high humidity.
34% solids content
Diazo dual-cure photochemistry for high resistance
Water resistant with no softening
Solvent-based and UV curing ink resistant
Decoatable with Autostrip
Can be used with containers, glass, posters or self adhesive decals
INSTRUCTIONS FOR HANDLING & USE
MacDermid Autotype PLUS 7000 must be handled under yellow fluorescent tubes or a low wattage Tungsten light.
Normally, MacDermid Autotype PLUS 7000 emulsion is supplied in a two pack kit created with MacDermid Autotype PLUS 7000 and a powder sensitiser in a sachet. Mix the two components as follows:
Carefully open powder Diazo with a pair of scissors (for your safety, DO NOT OPEN WITH TEETH).
Add the diazo sensitiser DIRECTLY to the emulsion. (DO NOT DISSOLVE THE SENSITIZER IN WATER OR ADD WATER)
Stir the mixture for approximately 2-3 minutes for the emulsion to fully sensitize. Allow for the emulsion to de-gas for 15 minutes prior to use.
Prior to application, make sure that your surface is free of any contaminants like grease and particles. Using degreasers, haze, and ghost removers from Garston can help make sure you have a clean, prepared surface to work on:
MacDermid Autotype CPS Degreaser Concentrate
Ulano UlanoGel No. 23 Fabric Abrader and Degreaser
Chemical Consultants Enviroclean Natural Citrus-Based Degreaser
Stand the screen on its edge, angling it away from the user, and with a good quality trough you can follow these instructions:
Any screens that are coated with MacDermid Autotype PLUS 7000 must be placed horizontally, squeegee side up and stored under dark or yellow light conditions in a maximum temperature of 30° C (86° F). You may apply additional coats to the underside of screen with intermediate drying.
Correct exposure is crucial for the best stencils when using MacDermid Autotype PLUS 7000. Underexposure will result in a weak stencil and reduced resistance. You must have a clean area when using MacDermid Autotype PLUS 7000, so it is best to remove dust from the stencils surface and tape the positive areas. Place the screen inside a vacuum frame and expose. The following exposure conditions will provide the best stencil production results:
2kw metal halide - set at a distance of 120 cm for 3-5 minutes
3kw metal halide - set at a distance of 120 cm for 2-3 minutes
5kw metal halide - set at a distance of 120 cm for 1-2 minutes
125W mercury vapour - set at a distance of 50 cm for 6-8 minutes
UV fluorescent tubes - set at a distance 10 cm for 5-7 minutes
Thorn Graph X - set at a distance of 120 cm for 4-6 minutes
You may wash the screen from both sides using a strong spray of water. Keep washing until the entire image is visually clear and sharp. Remove excess moisture and dry at a maximum temperature of 30° C (86° F).
Use screen cleaner to remove any ink from the screen. Apply stripper to both side of the screen and let it stand for 5 minutes. Remove the stencil with a strong stream of water or a high pressure stripper. Use dehazer on any ghosts or images that still remain.
INSTRUCTIONS FOR STORAGE:
MacDermid Autotype PLUS 7000 and its sensitizer should be stored between 3° to 20° C. Under these conditions MacDermid Autotype PLUS 7000 should retain a shelf life of 2 years once sensitized.
Extending the Life Of Your Emulsion:
Keep MacDermid Autotype PLUS 7000 cool and out of the humidity. This will help to make sure that it lasts its full shelf life.
Close properly and maintain an airtight seal after each use.
Mix the emulsion gently to ensure all of its components are homogenous.
Label the container with each date that it has been used to make sure that the contents are still within the shelf life
