Here's what I use:
1. A two-hole punch (common item at office supply stores).
2. Registration pins (1/4" diameter steel pins of varying heights, attached
to a small, thin sheet of stainless steel). These pins are made by Milton
Bregman Mfg. Co., Inc., and are available through printing supply dealers.
The first step is to visually register the color separation negatives on a
light box and then securely tape them together. Then punch one edge of the
negatives with the two-hole punch. (If your negatives lack a wide border,
create one by taping a 1" wide strip of scrap negative onto them). Now you
have three negatives in register with two 1/4" holes punched in them. Peel
the tape off of the negatives and separate them.
Use the two-hole punch to punch the printing paper. Now insert two
registration pins through the back of the paper and attach the desired
negative on top for exposure. After processing, use the pins again to
attach the other negatives for subsequent printing. In theory, everything
will be in perfect register. In actual practice, slight
expansion/contraction of the paper due to changes in relative humidity will
affect registration - most noticeably at the end of the print farthest away
from the pins.
This system is inexpensive, fast, easy, and accurate. It's a significant
improvement over trying to visually re-register negatives onto prints, and
taping the negative in place. It's very effective for three-color gum
printing, or other situations requiring accurate re-registration of a
negative for multiple printing, e.g. normal gum printing.
