MAGNESIUM dies are primarily used for flat foil
stamped images, flat single, multi-level embossed, or debossed images. The beveled edges of the embossed or debossed
image will appear a little softer and not quite as crisp as those produced
copper or brass dies. Shorter runs and
routine commercial work are especially suited for a magnesium die. Deep etch
magnesium dies are the perfect choice when debossing leather or vinyl.
COPPER dies are used for the same application when
longer runs, or more durability, is desired.
Fine type, detail, and reverses hold better with copper. Copper dies are
generally more expensive than magnesium at the outset. Press make-ready is usually quicker with
copper dies because copper is a better conductor of heat.
BRASS dies can be used for all applications. They are usually the highest priced of the
three types. Brass dies are machined rather
than chemically etched as are magnesium and copper dies. Brass dies are exceptionally durable, and the
life of a die may be endless as brass can be reworked or repaired. Fine details hold well when foil stamping
with brass and brass dies are especially effective with combination dies.
When sculpted, multi-layered, rounded, chiseled or special
effects are required, brass is the die that can be used. When mixtures of depth or edges or crisp
bevels are needed, brass dies perform well.
Brass will provide a superior product when various interpretations of
artwork are required, including shapes, textures, or edges. Close registration among dies or to color is
held closely with brass dies.
COUNTERS. Precast fiberglass counters are used with
embossing dies to assure that all the image detail is transferred to the stock. The counters push the stock into the cavity
of the die allowing the stock to bottom out thus achieving the full embossed
depth. Counters are usually registered
in position to the metal emboss die by a drill and pin system, or they can be
taped into position for registration.
