To combine an engraving with set type, simply slide the Wafer Die into the WHOC. Set the type
using the Open Chase Type Holder and then drop the WHOC into the Type Holder. Complete the
setup with spacers and lead rules and secure it with the Quoins. Insert the Type Holder into the
Heater Platen as usual.
Doing Test Imprints
Before imprinting any merchandise, always make a test imprint to check spelling and imprint quality.
The three essential factors for a quality foil imprint are the proper: TEMPERATURE, PRESSURE
and DWELL.
TEMPERATURE
Temperature is controlled by the setting you select on the controller and
monitored by an easy to read Temperature Gauge.
PRESSURE
Pressure is controlled by how hard you press on the Handle on a handle-
operated machine, and by the air pressure regulator on an air-operated
machine.
SOME NOTES ON PRINTING PRESSURE
•
The correct amount of pressure applied by the type against the article to be printed is
essential for high quality printing. Too much or too little will produce results that are
unsatisfactory.
•
Soft papers, smooth ribbons, vinyl's, leathers and plastics, require less pressure. Materials
with slight texture will require somewhat more pressure. Materials with pronounced
textures, in most cases, should be avoided.
•
Sometimes a careful choice of type style can overcome the problems associated with
texture. Medium to heavy textures might be successfully printed provided the type size is
not too small, and that the type style has been designed with thin, light lines. The printing
surfaces of such type are sharper, making it easier to penetrate heavier textures than a
type design with heavier strokes.
•
In addition, the printing area will have a definite influence on how much pressure to
apply. The heavier or more massive the printing area, the greater the pressure required.
Lighter and smaller printing areas require less pressure. For example, if the print pattern
contains five or six lines of type, somewhat more pressure will be required than if it
contains only two or three lines of the same, or similar, type size.
•
It is, therefore, important that careful consideration be given to the texture of the material
being printed, and to the size and density of the type/engraving being used. All of these
factors have a direct bearing on the amount of pressure required to produce the desired
results, or whether the desired results can even be achieved.
DWELL TIME
Dwell is the amount of time needed for pressing the hot type against the foil to
get a desired impression. The proper dwell time allows the foil to release
evenly at all points on the printed surface. The user controls the dwell time on
a hand-operated machine. On an air-operated machine, the setting you specify
on the electronic timer controls the dwell time.
1. Release the Side Screw and adjust the Gauge bar to fix the position for the article(s) to be
imprinted.
