ROLL - VISION 18 CAP FILM 25"X394"

18 Micron

HOW TO USE:

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 THE FILM: Cut a piece of Vision to size, be sure that it has been wiped free of dust, and place it emulsion (duller) side up on a flat surface. If the work surface is smooth, put a single sheet of newsprint under the film to prevent sticking between the work surface and the smooth backing sheet of the film. Starting in one corner, lower the wet screen printing side down onto the sheet of Vision. The water softens the emulsion layer, which is attracted up into the mesh structure by capillary attraction. Immediately, make a light squeegee stroke across the screen, as if printing. This embeds the softened emulsion deeper into the mesh structure and speeds drying time by removing excess water from the film and fabric. Use paper towels to wipe off excess water on the squeegee, the inside of the frame, the open fabric, and the backing sheet of the Vision film. (Water left on the backing sheet causes the emulsion to dry unevenly; water left on the fabric or in the frame may cause streaking when the screen is lifted to dry.)

For large screens:

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 2500 Series Ink Degradent to remove all excess ink from the frame. Remove the emulsion with Screen Systems 2500 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.
