Magnesium Foiling Dies

Centurion Graphics manufacture high-quality magnesium foiling dies (hot foil printing plates) in various thicknesses for hot foil stamping.

These are sometimes referred to as foiling dies, hot foil dies, hot foil blocks, foil blocks, hot foil printing plates or hot foil stamping plates.
The print quality is the same for all magnesium foiling dies, however, there are differences. The differences are the cost along with the maximum possible relief or etch depth.
All foiling dies are hand finished and inspected before despatch. They have chamfered edges on the top and are also filed down on the back edges to remove metal burrs.

How are foiling dies made?

The process of etching magnesium foiling dies undoubtedly requires a lot of skill and experience because the chemistry that makes up the etching "bath" has a limited lifespan.

Therefore, the operator has to understand what state the chemistry is in for each plate to ensure a clean etch.

Importantly, the temperature range importantly has to be kept within a 2-degree tolerance. As a result, when the "bath" is at it's strongest, the heat generated from the etching of unwanted material can be difficult to control.
Each plate is obviously different because of the arrangement of the customer's artwork. However, our team at Centurion Graphics have been etching magnesium plates since 1981, some 38 years. Consequently, we have the necessary experience and equipment to deal with this challenge.

ALL of our magnesium printing plates are capable of holding very fine detail required for high-quality foil printing and are also compatible with virtually any foiling machines.

They are sometimes referred to as "zincos" because they used to be made of zinc.
They are available in different thicknesses or "gauges", the 3 most popular gauges we stock are shown above. 

Nevertheless, we can also supply 3mm, 5mm, and 7mm upon request.
