Application Tape
The top layer of the legend. Normally made of highly dimensionally-stable paper with a low tack adhesive. This holds the various components of a legend together in proper registration. It is removed and discarded after application.
Hinge
A piece of masking tape which holds the legend in exact position for application, yet allows it to be turned over for easier removal of the release liner. It is either placed across the top of the legend (horizontal hinge) or up and down through the middle of the legend (vertical hinge).
Legend
A line or lines of lettering, or a set of graphic images with or without text, together with a top layer of application tape and a bottom layer of release liner.
Release Liner
The bottom layer of a legend. This is removed from the adhesive side of the lettering just prior to application
Squeegee
A plastic application tool designed for applying pressure-sensitive films. Stiffer than window squeegee, it requires about 15 pounds of pressure to flex it.
Tack
A piece of masking tape used to make positioning moves with a legend before applying the hinge. As an example: When applying graphics to a vehicle, tack every legend into place before actually applying. This will give you a chance to find the overall layout to see any problem areas. Then apply hinge(s) and proceed with the application.
Wetting Solution
A mixture of dishwashing liquid and water. Works best when only enough soap is used to eliminate water beading. Use about 1/2 teaspoon to a quart of water. Too much will result in excessive drying times. It is used to be temporarily defeat adhesive action in order to position legend without wrinkles or bubbles.
