Aiming at the defects of the current hot stamping technology, in order to promote the promotion of the hot stamping process in the digital post-press and advertising industries, the large-format digital hot stamping technology solves the defects of the traditional hot stamping technology in the digital post-press promotion. The preparation of hot stamping plates leads to long hot stamping process, many processes, and high pollution. It is impossible to realize large area, one piece hot stamping, instant printing, and digital hot stamping technology only needs cutting, positioning, waste disposal, and waste disposal. In one step, hot stamping technology can be applied to the surface decoration of publicity carriers commonly used in advertising industries such as large-format posters, personalized calendars, and roll-up banners. The key technology is:
1. Multi-layer bronzing film technology: integrate the key technologies of bronzing and stickers to design a multi-layer bronzing film structure. Each of these layers plays its own role and is indispensable. The function of the bottom paper layer is to support the 6-layer structure on it, and at the same time, it can prevent the transfer layer from sticking when stacking or rewinding; the positioning layer is to ensure the positioning of the independent unit in the graphic during the hot stamping process; The support layer mainly supports the transfer layer on it, and at the same time facilitates the waste discharge in the hot stamping process; the transfer layer has an interlayer structure similar to hot foil, in which the optimized combination of the layers ensures the smooth transfer of the hot stamping process. Smooth waste discharge, high-strength graphics and text to the printed substrate. The structure has applied for 2 national invention patents and 1 utility model patent.
2. Hot melt adhesive technology: A special process is used to prepare a liquid hot melt adhesive with low melting point, high viscosity and easy operation. The existing hot melt adhesives on the market are mostly EVA hot melt adhesives for book binding, PU hot melt adhesives for shoes and hats, and PVC hot melt adhesives for metal coating. The required hot melt adhesive (developed by China Institute of Printing Science and Technology) must meet the following indicators: low melting point, which is convenient for the hot stamping operation of the laminating machine and manual hot stamping machine; high viscosity, which is convenient for the bonding of the coating material; Solvent-free operation during hot melt adhesive application.
3. Pressure sensitive adhesive technology: change the formula and composition to prepare pressure sensitive adhesive with high viscosity and low overflow performance. Because the hot stamping film must undergo high-temperature embossing during the hot stamping process, the performance requirements of the pressure-sensitive adhesive are also very high. The pressure-sensitive adhesive that meets this performance can only be produced abroad at present, and our R & D team hopes that it can be localized in the future.
4. Cutting equipment: transform the existing laser equipment to manufacture low-cost, large-format cutting equipment. In order to meet the requirements of promotion, we have developed low-cost large-format cutting equipment, which is divided into contact-type cutting plotter series and non-contact laser cutting machine series. Among them, the cutting plotter equipment has low price and low energy consumption. The quality requirements are high; the laser cutting machine has no special requirements for the quality of the bronzing film, but the price is high and the energy consumption is large. In response to different customer needs, we have launched the following three solutions.
Small format hot stamping solution-for small format hot stamping market: personalized invitations, greeting cards, packaged gifts, book covers, etc .;
Large format hot stamping solutions-for the large format hot stamping market: roll up banners, banners, posters, streamers, etc .;
Super Large Format Hot Stamping Liberation Program-For the super large format hot stamping market: wall posters, car posters, large outdoor advertisements, etc.
The large-format digital bronzing technology is suitable for the surface finishing technology of quick print shops, digital printing companies, and advertising companies. The outstanding features of this technology are simple process, low initial investment, and low maintenance costs.
