Brief introduction of several different types of bronzing printing process
Lettering, commonly known as "hot stamping
", has a long history in our country. It means to burn the text and patterns of materials such as colored foil on the front or back cover of the hardcover book cover, or to emboss various convex and concave book titles or patterns by hot pressing. Nowadays, many fast printing companies are also using different types of hot stamping
Cold stamping: It is not necessary to use the heated metal printing plate, but to transfer the metal foil by printing adhesive. The cold stamping process has low cost, energy saving and high production efficiency. It is a promising new process.
Bump hot stamping
(also called three-dimensional hot stamping): Use modern engraving technology to make up and down matching female and male molds. The hot stamping and embossing process is completed at one time, which improves production efficiency. The mold made by electric engraving can be curved to achieve the three-dimensional relief effect that is difficult to achieve with the mold made by the general corrosion method. The emergence of embossing and embossing enables the embossing and embossing processes to be completed at the same time, reducing the process and the waste caused by inaccurate overprinting.
Holographic Marking: Using computer technology to change the amplitude and frequency of the grating to make the effect more vivid and clearer than the calculated pattern. If this kind of holographic mark is used as the original copy, a lot of holographic loss will be produced, so as to achieve the purpose of anti-counterfeiting. According to the characteristics of the hologram hot stamping mark, it can be divided into continuous holographic mark hot stamping and independent holographic mark hot stamping. Continuous holographic logo hot stamping is a replacement product of ordinary laser holographic hot stamping. Independent holographic logo hot stamping is to make the holographic logo on the anodized aluminum into independent trademark patterns, and there are alignment marks beside each pattern.
The holographic mark can not only have very good anti-counterfeiting performance, but also can incorporate special numbers or characters into the holographic mark according to customer needs. The hot stamping of the holographic logo on the packaging carton not only requires the hot stamping of the holographic logo on the surface of the substrate, but also has a relatively high overprinting accuracy, and it is more and more widely used in high-end carton packaging.
