Disclosure
Techniques
Place a sheet of paper over the
transparency and move it down to
expose succeeding lines of type.
Attach strips of opaque paper to the sides of the mask in order to
cover portions of the transparency image, and then flip the strips to
expose image.
Place an opaque sheet over the transparency containing a cutout slit
which exposes lines or copy area in sequential order as it is moved
down or across the copy.
Overlaying
Techniques

16. Overlaying
Techniques
After making a sketch of the content for the
transparency, decide which part will be the base
and which will be used for each overlay.
Prepare a master drawing for each separate part.
Make register marks in two corners of each master that match marks previously
put on the sketch.
Prepare the transparency from each master.
Mount each transparent sheet: base under the frame, and overlays on the top
sides. Use the register marks for proper alignment.
