Seal technology

When manufacturing seals and printed materials, we use a range of precision techniques that combine functionality, security, and design. From embossing and blind embossing to die cutting and digital die cutting, each method gives the result a unique look and protective properties. Below is an overview of the main technologies we work with.

Embossing (with foil)

Also known as gold stamping/hot stamping/thermo stamping/hot embossing. This is a method of transferring foil using pressure and heat. The die clamped in the machine is heated to a specified temperature and, when pressure is applied, a special bottom layer of foil is activated – the motif is transferred to the printed material. We use flat-to-flat and flat-to-cylinder printing.

Blind embossing (without foil)

Experts also refer to this as Braille / dry seal / embossed stamp, which we also use in letterpress printing, similar to embossing. Embossed printing technology without the use of ink or foil. A three-dimensional image is created on the desired material – positive (raised) or negative (recessed). The relief is pressed out in the machine under high pressure between the die and the counter die. During production, it is also necessary to take into account the weight of the material to which the blind embossing is applied. We choose from several die production technologies – single-level, multi-level, plastic transition.

Die cutting

In the final technological step, we cut the holographic sticker – seal into the desired shape. This die cutting is performed mechanically using a die cutter of the desired shape – ideal for larger quantities.

Digital cutting

Digital cutting is performed using a laser beam to cut the sticker into the desired shape – ideal for smaller quantities and more complex shapes. Microperforation and notches are also possible. There is no need to produce a cutting tool.

What are printing plates and dies?

We use a special die – a printing plate – to produce security seals and stickers. Depending on the complexity of the logo, graphics, and expected print run, the plate is produced using several technological processes, which we also combine. We use brass, magnesium, steel, bronze, plastic, and resin dies.
