Cold Foil What Is Cold Foil Transfer May 24, 2017

Cold Foil What is cold foil transfer? Cold foil transfer is not a new concept, but it has been widely accepted in recent years. Several major printing equipment manufacturers have adopted a highly integrated approach to this technology, making it a constant, efficient and mature process.

  The process of saying a lot of stomach, such as cold foil transfer, cold stamping or cold foil printing, but from its basic principles, the cold foil transfer of the term may be more appropriate, because it is neither hot stamping, nor a Worthy of the name of the printing process. Hot stamping and cold foil transfer of the main difference is the process of cold foil money does not need heat.

  Cold Foil The main reason why cold foil transfer is lost is that the process is relatively easy to mechanically integrate with the offset press flexo machine. The discussion below relates to the connection of cold foil on the offset press because, in addition to an important technical detail, the concept of cold foil is equivalent to offset and flexographic printing.

  The ultimate purpose of the cold foil transfer is to attach the foil material to the printing material, but this is the ultimate similarity. Cold foil hot stamping and bronzing different, it does not need hot stamping template. Instead, the image carrier of the printing process defines the place where the foil is to be attached, and in the offset printing, the offset sheet is used.

  Some of the newer multi-color offset presses can be fitted with a cold foil transfer system to print multi-color images and complete the foil operation in one sheet of paper.

  Printing on the first unit of the press is a special oily adhesive that can be achieved through conventional offset printing units and plates. The adhesive printed on the printing material represents the image area, and the second printing unit will transfer the cold foil to these adhesives. Since the rheological properties of the adhesive are similar to that of printing inks, extremely fine image elements can also be transferred to substrates 2-28.

  The metal foil feeding roll is unwound and then entered into the second printing unit like the leather cloth and the impression cylinder is printed with the embossed contact area. The adhesive adhesive pulls the foil layer from the polyester sheet base and transfers the weight onto the printing material The Use the foil in the rewind rewind as shown in the second stage.

  If the press has six printing units, the area of the foil can be overlaid with four other colors, including four-color overlay images. Due to the combination of this process and the combination of silver and gold metal foil base layer, can produce a good combination of color and effect.

  Cold Foil Whether traditional or UV inks can be used for foil overprint, but the traditional ink in the overprint and then coated with a layer of glazing.

  The use of an offset printing process to carry out these two operations has more benefits in terms of processing and material cost savings, because the image carrier (printed) Version of the preparation of the work and the use of these two materials in the use of offset printing plate than the use of hot stamping die greatly reduced. In addition, the offset printing process has been used to prepare the cold foil transfer image carrier required pre-press processing workflow for printing and hot foil two components for processing. Will make this combination process is significantly simplified.
