What Materials Do You Need For hot stamping foil?
In hot foil stamping, which is also referred to as foil printing, rolls of a pigment or a metallic foil are used. It is available in both matte and glossy finishes, as well as a wide assortment of colors — typically gold, silver, copper and holographic metallic. In addition, various patterns can be applied, or pastel foil, a flat opaque color, or a white special film-backed material. The foil material used in hotstamping is composed of several layers, including a polyester carrier, a release layer, and various layers of lacquer, image and metal, plus an outer adhesive layer for sizing. SixB Labels can offer you an impressive variety of colors in both matte and gloss finishes for hot foil options.
Hot Stamp Foils In A Variety Of Colors
Foil can be applied to a wide variety of substrates as well. Paper, carton board, fabric, leather, and plastics are typical choices of surface. While foil can be applied to foil, the application can prove more challenging.
What Equipment Is Used for Stamping?
Hot stamp dies have evolved, along with the process itself. In earlier times, hot foil stamping employed hand-set lettering or was accomplished through the use of custom-engraved dies. Early hot foil stamping was a very labor intensive process, so it was first used almost exclusively for literary titles and book covers. But by the late 1800's and early 1900's, modern hot-stamping foils were being developed, and by the 1930's it was possible to apply gold to polyester film.
In order to hot stamp, foil must be forced against a substrate by a heated die, normally made of brass, and supported by either a counterplate or counter cylinder, in a process somewhat like that of letterpress or engraving. Pressure plus the activation of adhesive sizing creates the attachment between the foil and the substrate, aided by the melting of the release layer.
The image below shows a foil stamp die with a blade held in place by an acrylic form, which is designed to be mounted to a machine plate. The image shows the backing foam used to protect the exposed blade, which is taller than the acrylic form.
Along with the foil stamp die pictured below, an 11 pt. (.153 inch) thick magnesium plate, also designed to be machine mounted, would be used in the stamping process. This unit, which employs an etched image, is heated, and the foil is run between the plate and the substrate so that the image can be transferred, leaving behind an impression of the design of the die. In order to create a 3D image, foil stamping can be combined with embossing.
What Equipment is Used for Embossing Labels:
Embossed labels are produced when heat and pressure are used to create a three-dimensional, raised relief image or design in paper and other materials. Two dies are needed for this process; a raised die and another that is recessed; these are fitted together, and the paper is pressed between them to create the image. When creating an embossed foil label, a design that requires thicker, bolder lines is easier to execute. Producing a label using a complex image with multiple fine lines can prove more difficult. Blind embossing uses neither ink nor foil to create an image, and produces a subtly raised design; it can be combined on the same label with foil stamping.
