Chromaline ProCap 30 Diazo Capillary Film – Precision Meets Durability

Pre-sensitized diazo capillary film from Chromaline is designed for compatibility with plastisol and solvent based inks. Printers will appreciate its “workhorse” durability for demanding print runs, and its “user friendly” convenience. In addition to the normal benefits of a capillary film, Pro/Cap provides these extra advantages:

• Superior film penetration and adhesion
• Economically Priced Pro/Cap

capillary films are recommended for screen makers demanding high edge definition and reliable durability for quality imaging in even the longest print runs. Available in both rolls and custom cut sheets.

MATERIALS REQUIRED

• Exposure unit
• Washout sink
• Clean work area

RECOMMENDED:

• Drying cabinet
• Pressure washer
• Exposure Calculator

INSTRUCTIONS:

DEGREASE – Using a mesh degreaser, work up a lather on both sides of mesh. (Be sure to use only a high-quality mesh degreaser.  Rinse thoroughly.

WET – Capillary films require a thoroughly wet screen. With the screen in a vertical position, paint Chroma/Wet wetting agent onto the print side of the screen. (Use a separate brush just for this step.) Wait a moment, then flood entire screen with a garden type hose.

ROLL-DOWN – Cut the film to size and roll it up, emulsion side out. Reflood the screen with water and attach the roll of film to the top of the print side of the screen. With slight pressure roll the film down until the entire piece is in contact with the mesh. Use a window squeegee to remove excess water from squeegee side only.

DRY– Thoroughly dry the screen in a dark area (avoid high temperatures of 110 degrees F, 43 degrees C, and up). Remove the carrier just before exposing. If the carrier resists being pulled off, additional drying time is needed.

EXPOSE – With polyester 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 approximately 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 emulsion remover to both sides of screen. Scrub with a stiff nylon brush to ensure entire surface is wet and let it work for 30 to 60 seconds. Pressure wash out.

EXPOSURE GUIDELINES – Exposure times were determined by using an Exposure Calculator. Exposure times were set for a 5KW unit at 40″ from the frame. All screen mesh was yellow in color. Screens were coated wet on wet, once on print side and twice on squeegee side. Chromaline recommends use of an exposure calculator for correct times for your equipment. These figures are only a guide.
