Early gilding is not popular Hot pad printing technology is commonly called bronzing. The early gilding industry is not much in print. The reason can be summarized as follows: First, bronzing machines are still on small machines in the 1970s, such as manual bronzing. Machine, 13 inch × 18 inch Heidelberg throat machines, and smaller flat flat stamping machine. At that time, if there was a large area or bronzing in the field, they could not be hot-pressed. There were multiple versions of the paper and a large amount of paper to be quasi-adjusted. Also, the large paper was finely sliced ​​before it could be gilded, resulting in slow bronzing and slow positioning. , to the printer troubled. At that time, most of them were hot stamped hardcover cases, book covers, covers, envelopes, letterheads, greeting cards, etc., and hot box printing was not popular. The second reason is that due to the fact that hot stamping is not popular, it was not promoted until the early 1980s when local companies introduced large-scale hot stamping machines in Japan, such as escaping machines. After the promotion, the printing merchants can see the hot stamping full sheet, the nesting is accurate, and the goods are fast, so they have the ability to receive the hot stamping of large area orders; and even more fully introduce the Heidelberg hot stamping machine to make the hot stamping industry more flourishing. Until now, the demand for bronzing of printing and packaging has increased.
In fact, bronzing seems simple, but it has its own learning. The bronzing industry can be briefly divided into paper stamping and plastic stamping. Machines in the two types of industries are also different. Paper type bronzing machines can be roughly divided into:
First, manual small hot stamping machine, only small size paper can be hot stamping.
Second, flat pressing hot stamping machine, this model has a variety of sizes, from small to hot size of the size of the folio paper, with a computer program to pull the gold foil, the speed is slow, the process is mostly manual operation.
Third, manual-type beer box-type hot stamping machine, this type of machine is similar to manual beer box machine, the size can be hot stamped to 28 inch × 40 inch paper, the process is also mostly manual operation, the speed is relatively slow, rarely used in Hong Kong.
Fourth, Heidelberg automatic rolling gilding machine, Heidelberg letterpress printing machine can be said to be the oldest top machine. This hot stamping machine was actually refitted from a letterpress machine. Now that letterpress printing has been replaced by offset printing, the machine factory has used its brains to convert it into a fully automatic hot stamping machine. This is mainly to convert part of the dial into heat. The board and the place where the bronzing plate is installed, and a gold-recovery paper component is installed. This machine has a good effect on hot lines and large fields.
Fifth, flat automatic hot stamping machine, similar to automatic beer box machine, the price is more expensive, not many users, but the speed is the fastest models, hot stamping area is also larger.
Sixth, automatic air throat hot stamping machine, modified by Heidelberg live version of wind throat machine, paper size of 13 inches × 18 inch, fast, is the essential tools for the early hot stamping factory
Gold foil needs to cooperate with the material In addition to the hot stamping machine, but also have the combination of hot stamping foil, gold foil seems thin, in fact, it consists of five layers of material.
Many people have misunderstood that a kind of gold foil can be used to iron any kind of paper products. In fact, many kinds of gold foil are used to match different types of hot materials, such as PP film or polished paper products, metallic ink, cloth, PVC glue, etc. Hot and thin line stripe or large field and other materials and printed materials, must choose different materials of hot gold foil to cooperate. Therefore, the price of flashing hot stamping foils ranges from RMB 10 to RMB 1,000. It also depends on the nature of the country of origin and the material. The price of matt-colored ironing cloth and scratchable gold foil is about 700, and that of laser foil is RMB 1,000. . Gold foil manufacturers have manufactured 10 kinds of gold foils of different colors and different qualities to suit different paper products. On a scale, a well-managed hot stamping factory also makes samples of hot stamped gold foils and additional numbers for customers' selection. Customers can also designate a brand. Hot stamping foils, such as the international toy company "Barbie" dolls, will specify a certain brand, a certain number of gold foil.
