Pay attention to the temperature during the bronzing process

If the bronzing effect is good, it is necessary to have a suitable gold foil with good thermal stability, and it is also necessary to cooperate with the bronzing machine type, such as flat pressing and rolling type, which have different effects, and the matching temperature, pressure, and hot pressing pressure. Elements of time.

Temperature - The most suitable temperature for bronzing operations is the ability to imprint a clear texture at the lowest possible level. The platen stamping machine has a heating plate temperature of about 110°C, and a roll-type stamping machine has a temperature of 140°C to 150°C. The most suitable temperature is to be found in the test mode. Excessive temperatures will change the foil stamping paper. Bad and blurred lines.

The pressure-pressure depends on the hardness of the material and the texture of the surface. Surface smooth or soft material, lighter pressure, rough or hard, it can be heavier pressure. The flat pressing hot stamping machine is the synchronous hot pressing of the whole sheet. The hot line of the hot rod machine is the line pressure and then the flat pressure. The rolling machine is similar to the line pressure of the Koo machine.

Stoppage time - based on the shortest possible effect of hot stamping, the time is too long, the gold foil and the hot stamped paper are damaged, and the flash foil will become a matte foil.

There are also patterns to be hot stamping and printing pattern sets are accurate, when using a rolling hot stamping machine or a large area of ​​hot stamping, there is a need to foil the negative film film first reduced to 99.8% to 99.7%, before the arrangement of electricity Edition, so that the electric version is heated and swelled on the heating plate. It turns out that the current scratch-off raffle tickets can also be made using the bronzing method.

The price of bronzing depends on which type of gold foil is used, whether gold foil is wasted, the degree of closure, type of layout, quantity, size, and so on. Therefore, there is no standard calculation method for uniform quotation.
