An economical alternative to direct emulsion in material cost and because it offers significant savings in labor and production time. It adheres perfectly, dries faster than direct emulsion, and exposes very quickly. Available in 30 micron for mesh counts ranging from 230 - 419 threads per inch and 50 micron for mesh counts ranging from 86 - 156 threads/ inch.Coated on 3-mil (75-micron) matte-surface polyester. EZ-FILM can be adhered with plain water or with QTX direct emulsion in the direct/indirect mode. EZ-FILM is designed for plastisol and should be used with non-aggressive solvent-based inks and mild washup solvents. Screen openers and aggressive solvents will make screen reclaiming more difficult.
HANDLING:Handle under yellow safelights. Avoid exposure to sunlight, flourescent and incandescent lights. It is important to remove any contamination, residual inks, cleaning chemistry, or general dirt and dust. Screen Systems 5230 Haze/Ghost Remover will remove residual ink and/or emulsion. Screen Systems 5505 Screen Degreaser will help eliminate any further contaminants. Completely dry the screen before coating
ADHERING WITH WATER:Reverse roll the film so that the emulsion side is out. Thoroughly wet the mesh. With the screen vertical, place the rolled up film where you want the film to start. Gently roll the film evenly down. Place the film on a build up board with the emulsion side up. The build up board should be slightly smaller than the inside of the frame. Place the screen, squeegee side up, on top of the film. Squeegee excess water off of the image area. If part of the film isn't adhered, you can either use a spray bottle with water to dampen the area
ADHERING WITH EMULSION: Place the film on a build up board with the emulsion side up. The build up board should be slightly larger than the film. Place a piece of masking tape just above and below the film on the squeegee side of the frame. Pour a bead of QTX Emulsion on the top piece of tape. Use a 60 to 70 durometer squeegee to draw the emulsion across the film from tape to tape two times.
DRYING: Dry the coated screen horizontally with the print side down in a clean light safe area. The following will help to ensure complete drying: 86° to 104° degrees F (30° to 40° C). 30% to 50% relative humidity with good air circulation
EXPOSURE: Clean the film positives and vacuum frame glass prior to exposure to minimize pinholes. Exposure is affected by mesh color, emulsion type, coating thickness, lamp type and the age of the bulb itself. For best results use an exposure calculator to determine the correct exposure time. It is important that a lamp designed for exposing screen printing emulsions is utilized. Thick films require longer exposure times than regular film. The thicker the film, the longer the exposure.
WASHOUT: Use warm water to rinse both sides of the screen, the use a pressure washer to remove film from the substrate side. Continue washing until the image is clear.
RECLAIMING: Use Screen Systems 2300 Series Ink Degradent to remove all excess ink from the frame. Remove the emulsion with Screen Systems 6000 Series Emulsion Remover. Use Screen Systems 5230 to remove haze and ghost if required. Degrease with Screen Systems 5505, rinse both sides thoroughly and let dry
