MASKING OFF
In the next several exercises you will need to
mask off a square area.
Make a mask from 4 pieces of scrap paper (fig.
8). These masks are
held in place by masking tape, keeping the
atomized material from creeping into the margins
around the area. When using masks spray over
the edge.
EXERCISE THREE/EVEN TONES
FIG. 9
FIG. 10
FIG. 11
To accomplish a flat tone, we will airbrush a fine
consistency of paint from left to right at the top
of the taped area. Hold the airbrush about four
inches from the surface of the sheet. Be sure
to spray a portion of the tape so that no light
line shows when the masking tape is removed.
Use the trigger technique on page 3 throughout
this lesson. Now airbrush from right to left,
overlapping the previously airbrushed strokes.
Continue down the entire sheet, trying not to
create a line pattern with the airbrush.
Overspray the tape, both right and left and top
and bottom. Begin at the top again and do the
entire page. Repeat the exercise until you reach
the desired smooth coverage of the entire area.
Do not attempt to cover the entire sheet with a
heavy tone at one time. Build the tone gradually
(figs. 9-11).
Make sure the work and tape are dry before
removing the masking tape. This should be
done carefully to avoid tearing the surface of
the paper it is adhered to. If your first results are
not satisfactory, repeat the lesson until you are
satisfied.
EXERCISE FOUR/VARYING SHADES

TECHNIQUES TO USE
Masking or frisket is used mostly when more
than one color is applied. A new frisket is cut
for each color and covers any area that should
not be sprayed. For contour masking (models,
ceramics, etc.) use masking tape, scotch tape.
Film and cut to desired shape. Make sure the
edges are pressed firmly against surface to
prevent underspray.
