In the packaging and printing industry, the bronzing process has become a very common post-press processing process in printed matter, and the technology is also very mature. The following five bronzing methods are introduced for you. These five kinds of processing can be applied to printed matter, and each has different characteristics. You can choose different bronzing methods according to different designs.
Flat ironing is the most commonly used hot stamping method. Only the content that needs to be hot stamped will have metal, and other places will be blank or printed. The purpose of flat ironing is to highlight the location of bronzing and to iron the most important materials in gold. Compared with other processes, such as reverse ironing and multiple bronzing, flat ironing is less difficult and less likely to make mistakes. In addition, because it is the simplest bronzing process, the loss of paper will be less.
Inverse ironing is the opposite of flat ironing. Metal hollowing is used to highlight the blank position, and the bronzing part is used to set it off. The usual practice is to surround the graphics and text to be highlighted with a large graphic, the surrounded graphics will be hot stamped and the graphics and text to be highlighted are hollowed out, thus forming a reverse hot stamping effect. When doing reverse ironing, if the foil area is large, the price will be higher. Moreover, the graphic and text lines to be highlighted should not be too thin (more than 6pt is required), otherwise, the effect of the finished product will be unsatisfactory. If the special paper is used for hot stamping, it is necessary to consider the characteristics of paper texture and other characteristics. If the surface is not smooth, it is not recommended to use reverse hot stamping, because the fineness of large-area hot stamping is easily affected by the paper texture.
The overlapping of stamping and hot stamping is a processing technology that tests the skill of the master, and its printing design is a clever combination of hot stamping and printing colors. The master will do the printing first, then the hot stamping. The hot stamping process has high accuracy on the position, but the effect of the printed product is first-class and full of fun. This approach is not only a test of the master’s skill but also a test of the designer’s thinking in matching colors.
Multicolor hot stamping
To highlight the graphic and text, many designers will hot stamp the same graphic twice or more. This is called multi-color hot stamping. This hot stamping method also requires a high-precision hot stamping method, which is similar to the hot stamping overlap. When there are multiple colors for multiple hot stamping processing, it is necessary to pay attention to the hot stamping position and the compatibility of gold foil. If the designer sets the distance between the two hot stampings too short, there is a chance that the two colors will stick together.
Three-dimensional hot stamping
The combination of bronzing and embossing technology is three-dimensional bronzing, which makes the bronzing part protrude and forms a three-dimensional relief effect. However, it should be noted that the back of the three-dimensional bronzing will have a concave effect, so remember to leave the back blank when designing, otherwise, the graphics or text will be affected.
