RyoCap Series Capillary Film is designed for use with plastisol, solvent, and limited water based inks (short runs).
Opened and unopened rolls or sheets of film should be stored at temperatures of less than 80°F for maximum shelf life.
HANDLING THE FILM:
The film should be handled under low wattage tungsten or yellow light safe lighting. The film should be returned to the container after cutting off the required length. Do not kink the film as this could affect adhesion to the mesh. The film should be handled wearing light cotton or lint free gloves to avoid contact with the emulsion surface. Do not allow the film surface to come in contact with water.
All new mesh should be abraded vigorously on the printing side with before use.
ADHERING TO THE MESH:
Large and small screens: Cut the film to size and place the film on a dry, flat surface. Roll the film, emulsion side out, around a plastic tube leaving approximately 1" unrolled. Spray the mesh with water and wipe the excess water from the perimeter of the frame to avoid water drops running into the adhered film. Contact the rolled film leading edge onto the top of the wet vertical screen and unroll the film down the screen, thus adhering it to the mesh. Remove excess moisture from the inside of the screen with a clean squeegee.
Wipe excess water from the perimeter of the frame with an absorbent cloth then proceed to drying. Small screens only: Place the film, emulsion side up, on a raised pad and lay the dry degreased screen on top. Using a hand spray water bottle, spray water onto the mesh until the film is completely wet. Squeegee off the excess water from the inside of the screen. Wipe water from the perimeter of the frame, then proceed to drying.
To dial in exposure times we recommend getting this simple exposure calculator the only costs $11 and really helps you dial in correct exposure.
DRYING THE SCREEN
The screen can be dried with cold or warm air, maximum 100°F. Thorough drying is essential for optimum results. When the support has been peeled off, continue drying for a few minutes to ensure the film is completely dry. Drying should be in either dark or yellow light conditions.
STORAGE OF SCREENS:
After applying the film to the screen and drying, the screens can be kept in the dark for up to a week before exposure, provided that reasonable temperature and humidity conditions are maintained. If storage of the screens is anticipated, it is recommended that the backing sheet is not removed until the screen is about to be exposed.
After applying the film to the screen and drying, the screens can be kept in the dark for up to a week before exposure, provided that reasonable temperature and humidity conditions are maintained. If storage of the screens is anticipated, it is recommended that the backing sheet is not removed until the screen is about to be exposed. These films typically expose at the same exposure times as other major brand capillary films. You can generally expose at those times and achieve good results. Starting point exposures at 40" on colored 230 mesh are listed below. Exposures will vary with mesh count, color, distance and lamp type.
Spray both sides of screen with approximately 80°F water spray to start washout. The majority of spray should be done from the printing side until image is completely defined. Finish washout by spraying inside of screen to remove any stencil residue.
Place developed screen in front of fan or in screen dryer. Make sure screen is fully dry before use. Do not exceed 100°F when drying.
Removal of stencils is easy. Spray SaatiChem Remove 1 on back or both sides for faster removal. Finish removal with high-pressure washer when stencil has started to run down screen. Allow the remover to do the majority of the work. Do not allow the stencil remover to dry out on the screen before high-pressure washout.
