What is bronzing?

Bronzing is the most brilliant embellishment process for all types of printed products.

It is particularly often used for the production (embellishing) of labels, greeting cards, packaging for high-quality cigars (cigar rings), cosmetic packaging and many other luxury products.

During bronzing, a "bronze powder" (brass alloy), which consists of pure metal flakes, is applied to a special adhesive. A bronzing machine from Matheoschat Bronzing Technology is used for this, which is connected directly to an offset printing machine.

The offset printing machine creates the print image of the product to be bronzed using an offset adhesive (gold size or „prep“) instead of a colored ink. The printed sheets fall from the delivery of the printing press directly onto the conveyor system of the bronzing machine and are transported into and through it.

Inside the bronzing machine, the sheets pass through an application system that evenly distributes the bronze powder over the printed sheet, a burnishing system that “massages” the powder into the gold size and finally the dusting or cleaning system, in which all excess bronze is removed so that the bronze powder only remains where the adhesive (gold size) was previously printed.

The result is a perfectly clean sheet with an evenly covered bronze layer of the highest brilliance and an incomparable metallic, satin gloss.

In contrast to all other finishing methods, where the metallized surface is smooth and two-dimensional, the bronze particles (“flakes”) are randomly aligned in the gold size and thus offer three-dimensional brilliance from every viewing angle!

Colour tones - pigments

In addition to a wide range of gold tones, from lemon gold, yellow gold, bright rich pale gold and intense copper-coloured ducat gold to fiery red, there are also various other types of powder that can be used with a new bronzing machine (Type Matheoschat - CB).

For example, pearlescent pigments (Iriobronze), silver flakes (aluminum flakes) or glass dust for an endless number of coloured underlays (Luxan).
