What is Hot Stamping?

Hot stamping is a straightforward process:

1. A die is mounted and heated,
2. Foil is positioned above the material to be imprinted,
3. A combination of heat, dwell time, pressure and stripping time control the quality of the stamp.

Foil stamping is environmentally friendly due to it being a dry process. It does not use solvents or inks and does not create any harmful vapors.

A successful hot stamping job is directly related to the quality of the original artwork. In order to insure the highest quality reproduction of an imprint, the original artwork should be “camera-ready”. The better the artwork at the beginning, the better the imprint reproduction result. The key to a successful hot stamping job is threefold; the first is creating a fixture to support the part firmly under the decorating area. Second, the fixture must also position the part for repeatability of the graphic location. And third, the fixture must allow the operator to easily load and unload the part from the fixture.

Foil is an extremely thin polyester film material containing a dry pigment that is transferred to substrate (such as: paper) by the use of heat and pressure.
Foil composition: Film carrier: The thinner the carriers while all other things being equal, the faster the foil will transfer
Release Coat: Allows the other layers to release from the film carrier upon application of heat &/or pressure in which this layer affects whether or not a foil is suitable for fine copy or heavy coverage
Lacquer, Tie or Color Coat provides a hard abrasion resistant surface to the foil when applied and carries the color tint in the form of pigments or dyes which is required to make gold or other colored metallic because the metallic layer is always made from aluminum.
Metal Coat: Generally composed of aluminum to provide the reflective qualities and opacity desired in metallic foils.
Adhesive or Sizing Coat: The final layer in the foil construction is the sizing which serves to bond the foil to the substrate being stamped.

TYPES OF MATERIALS

Metallic foil construction has a metal-like sheen and gives a shiny and shimmering look to the foil stamped design. Such foil paper is available in different metal shades such as gold, silver, bronze, and copper just to name a few. Pigment Foil Construction: Gloss Pigment Foil Paper not have a metallic look but has a very high glossy finish. Matte Pigment Foil Paper a dull finish as opposed to a glossy finish Holographic Foil Paper: hologram is a 3-dimensional image that can provide a distinctive appearance to specific areas of a digitally printed application.

Many other applications can be applied on the hot stamping machines without stamping or with the addition of stamping to it like:

* Debossing opposite of embossing it is indented
* Embossing by providing a three dimensional or raised effect on selected areas
* Blind Emboss provides a clean and distinctive or subtle image on paper stock does not include the use of ink or foil to highlight the embossed area.
* Registered Emboss a process that places the embossed image in alignment with another element created with ink, foil, punching, or with a second embossed image.
* Combination Emboss embossing is the process of embossing and foil stamping the same image. It involves imprinting and aligning foil over an embossed image to create a foil emboss.
* Pastelling the process of using a combination die to provide a subtle antique appearance to a substrate that is embossed and foil stamped.
* Glazing an embossed area that has a shiny or polished appearance.
* Scorching similar to glazing except that it is not used to polish the stock. Instead, scorching does what it implies: as the temperature of the die heating plate is increased beyond a normal temperature range, a scorched effect is created in the embossed image, which results in an antique or shaded appearance.
