Cold foil printing, also known as cold foil stamping, is a modern method of printing metallic foil on a substrate in order to enhance the aesthetic of the final product. . Cold foil printing can be done two ways: the older dry lamination process common in the offset printing industry, or the newer, more versatile wet lamination process, which is dominant in the flexo label indus
Copper foil is available in different types to suit various applications. The most common types include: [3] [4] Electrodeposited Copper Foil; Electrodeposited copper foil, also known as electrolytic copper foil, is produced by electroplating copper onto a rolling drum in a highly controlled manner.
Cold stamping, also known as press working, [1] is a manufacturing operation in which thermoplastics in sheet form are cold-formed using methods similar to those used in metalworking. [2] A precut thermoplastic sheet, possibly reinforced, is softened by heating to a temperature particular to the plastic in use.
The dry paint or foil used is impressed into the surface of the product. The dye-stamping process itself is non-polluting because the materials involved are dry. [2] Pressure and heat cause the relevant sections of the foil to become detached from the carrier material and become bonded with the printing surface. [3]
Cold spray additive manufacturing (CSAM) (also called cold spray 3D printing) is a particular application of cold spraying, able to fabricate freestanding parts or to build features on existing components. During the process, fine powder particles are accelerated in a high-velocity compressed gas stream, and upon the impact on a substrate or ...
Thermal-transfer printing is done by melting wax within the print heads of a specialized printer. The thermal-transfer print process utilises three main components: a non-movable print head, a carbon ribbon (the ink) and a substrate to be printed, which would typically be paper, synthetics, card or textile materials.
While not a true lenticular process, the Dufex Process (manufactured by F.J. Warren Ltd.) [60] does use a form of lens structure to animate the image. The process consists of imprinting a metallic foil with an image. The foil is then laminated onto a thin sheet of card stock that has been coated with a thick layer of wax.
The process is performed as follows: Sheet is adhered to a substrate with a heated roller. Laser traces desired dimensions of prototype. Laser cross hatches non-part area to facilitate waste removal. Platform with completed layer moves down out of the way. Fresh sheet of material is rolled into position.
