Hot stamping is a key in the production of cigarette package of post-press processing working procedure, among them, the hot stamping is a common way, it can use hot stamping equipment, through the compression, heating, the electrochemical aluminum hot transferred to the bearing surfaces.In the process of hot smoke package, there are several factors affecting the effects of hot stamping, among them, hot stamping pressure is one of the main influence factors.Here, the author combines many years of practical experience, hot stamping pressure on cigarette package printing effect and the adjustment methods are expounded briefly.
If hot stamping pressure, hot stamping on the surface of the cigarette package design is likely to become angry, counter loop phenomenon, even damage the bronzing version, bronzing version if it was not damaged, will greatly reduce the hot stamping version of the service life, increase the cost of production.At this point, can take the whole decompression or local relief way to solve it.Overall decompression is directly reduce the pressure of the equipment parameters;Local stress is in the single spell part or a small scale to reduce pressure paper, specific operation depending on the actual production conditions.
If hot stamping pressure is too small, hot stamping on the surface of the cigarette package design is prone to severe gold, a bit of quality defects.At this point, can take the whole pressure or local pressurization methods to solve.The overall pressure is directly increase the pressure of the equipment parameters;Local pressurization is in single spell or small scale increase fill pressure paper, specific operation depending on the actual production conditions.
Indicate that the operation of the whole stress and pressure of the whole method is suitable for ordinary hot stamping, this is because the ordinary bronzing version and bearing iron content of interface is a stable plane, especially large stamping products the most cultured is balance sheet of the pressure, if the local regulating operation method, is easy to affect the whole pressure due to uneven local pressure balance, thus caused by repeated fill pressure affect the production efficiency and not fill pressure effect.Moreover, ordinary hot stamping process is stable, hot stamping pressure is relatively easy to control.
Local decompression and the operation method of local pressure is suitable for stereo stamping, this is because the stereo bronzing version with iron bearing contact area is uneven, so graphic parts easy to appear off the edge, a bit, or paste gold phenomenon, and local regulating just can accurately adjust to the partial pressure of the problem, not only can improve the production efficiency, and to improve hot stamping version of resistance rate, saving the cost of production.It is important to note that the local regulating in three-dimensional cigarette package, had better use hand to tear fill pressure paper, and stacked them into a pagoda, it is not only beneficial to eliminate hot stamping parts of the air, still can make the pressure is more stable and uniform.
We know that the temperature of the hot stamping, hot stamping pressure, hot stamping speed between influence each other, so in the process of hot stamping, if slight paste gold hot stamping products phenomenon, can be appropriately increasing the hot stamping;If appear a bit hot stamping products, slight hot stamping on the situation, can be appropriately increased hot stamping pressure, improve the hot stamping temperature, or decrease the equipment running speed.
In addition, because the new stereo bronzing version of the sharp edge is compared commonly (ordinary bronzing version does not exist the problem), so in the first time before computer use, need to do some light processing, otherwise it will caused a lot of trouble for plate process.With fine sand paper burnish, for example, burr on the edge of the copper, or dip in with alcohol brush slightly the sheet with grinding plate, it is not only beneficial to plate, greatly improve the efficiency of plate, also won't appear when hot stamping stamping caused by hot stamping version of the edge is too sharp products the quality problem of the graphic part is pressed to wear, so as to ensure the quality of hot stamping products to meet customer requirements.
