cloth using a rubbing motion. When this has been done, adhesion will be instantaneous. Continue in the same manner
until the entire film has been adhered, wetting the small cloth as often as it is necessary. In adhering, always start from
one side of the screen and continue in the same direction to avoid wrinkles.
(5)
When the entire film has been adhered, take a thin straightedge or ruler and slip it under the film to carefully
free the screen from the layout sheet while loosening the restraining adhesive tape. Remove the silk screen frame from
the hinges and lay it on the table with the film paper side up. Allow the film to dry about 10 minutes.
d.
Removing the Backing Paper.
(1)
Start in any one of the four corners and slowly peel off the backing paper. Peel the backing paper so that
one can, at all times, see the film in order to prevent tearing any portion of it that has not adhered. Should any portion of
the film not adhere properly, do not remove the backing paper, but turn the screen over again and wet and dry that portion
(as in paragraph c.(4) above) to obtain the proper adhesion.
(2)
When the backing paper has been completely removed, if there are still some loose places, wet the cloth
with the adhering liquid and dampen the loose part from the under side of the frame. Pat the loose portion down from the
film side, thus completing the adhesion.
(3)
Fill in the open silk bordering the film with lacquer.
e.
Printing or Reproducing.
(1)
If the original sketch is the exact size of the copy to be processed, the original egistration strips applied
should suffice. If this is not the case, new registration strips should be set in place without disturbing or moving the layout
sheet.
(2)
Place one of the pieces to be printed on the table, snugly against the registration strips, and lower the silk
screen.
(3)
Place a small quantity of the first color of paint across the screen just above the design. Starting just above
the paint, pull the squeegee across the screen while making certain to apply firm and even pressure across the ,width of
the squeegee (see figure 6-9).
(4)
Lift the screen, remove the printed piece, and place it on a drying rack, as illustrated in figure 6-10. To
continue the process, insert an unpainted piece, lower the screen, and squeegee in the opposite direction.
(5)
When the first color has been applied to all of the pieces that are to be printed, the film or mast must be
removed from the silk and replaced with the film that was cut for the second color.
f.
Removing Film from the Silk.
