In addition to the normal benefits of a capillary film Magna/Cure provides these extra advantages:

  1. Exceptional print quality & durability
  2. Excellent solvent and co-solvent
  3. Easy washout
  4. Wide exposure latitude

INSTRUCTIONS

The Roll-Down Method of applying Magna/Cure Capillary Film

DEGREASE

Using a mesh degreaser, work up a lather on both sides of the mesh. (Be sure to use only a high-quality mesh degreaser.) Then rinse thoroughly.

WET

Capillary films require a thorougly wet screen. With the screen in a vertical position, paint Chroma/Wet wetting agent product (or similar product) onto the print side of the screen. (Use a seperate brush just for this step.) Wait a moment, the flood entire screen with a garden type hose.

ROLL-DOWN

Pre-cut the film to size and with dry hands, touch the film edge to the top of the screen. Put slight pressure on the film roll to assure consistent contact with the mesh, and roll down evenly. When the film is in complete contact with the mesh, use a window squeegee to lightly squeegee off excess water from the squeegee side of the frame. Do not use squeegee to press the film into the mesh.

DRY

Thoroughly dry the screen in a dark area, then remove the carrier. You will know the film is dry when the carrier peels off easily. If the carrier makes any noise when being pulled off, or resists being pulled off, additional drying time is needed.

EXPOSE

With mylar carrier peeled off, place the emulsion side of the positive against the print side of the screen in an exposure frame. Run an exposure test to determine your correct exposure.

DEVELOP

Gently spray both sides of the screen with tepid water. Wait approzimately 30 to 60 seconds, then wash the print side of the screen until the image is fully open. Rinse both sides thoroughly. Dry the screen completely, and you are ready to print.

RECLAIM

Apply Chroma/Strip screen reclaimer (or similar product) to both sides of screen. If using squirt applicator, scrub with a stiff nylon brush to ensure entire surface is wet and let it work for 30 to 60 seconds. Pressure wash it out.

SCREEN PREPARATION (new mesh only)

Scrub Chroma/Brade mesh abrader/degreaser (or similar product) thoroughly into entire screen area on print side of new mesh. This mesh pre-treatment will degrease the mesh and roughen it slightly to improve capillary film adhesion.

EXPOSURE GUIDELINE

Exposure times were set for a 5KW Metal Halide unit at 40" from the frame. All screen mesh is 230 yellow. Chromaline recommends use of an exposure calculator for correct times for your equipment. These figures are only a guide.
