Heat transfer printing is an emerging printing process that has been introduced from abroad for only over 10 years. The printing method of this process is divided into two parts: transfer film printing and transfer processing. Transfer film printing uses dot printing (with a resolution of up to 300dpi) to preprint patterns on the surface of the film. The printed patterns are rich in layers, bright in color, ever-changing, with small color difference and good reproducibility, which can meet the requirements of the pattern designer and are suitable for mass production; The transfer printing process uses a heat transfer machine to process (heat and pressure) the beautiful patterns on the transfer film and transfer them onto the surface of the product. After forming, the ink layer dissolves into the product surface, creating a realistic and beautiful appearance, greatly improving the quality of the product. Color printing is the process of directly spraying a logo onto a cup through spray painting.
Silk screen printing, also known as "screen printing," refers to the process of placing silk fabric, synthetic fiber fabric, or metal wire mesh on a screen frame and using manual lacquer film or photochemical plate making methods to create a screen printing plate. To put it more simply, the implementation process of silk screen printing is to create a film based on the advertising content, and then use the film to create a silk screen. The content that needs to be silk screen printed is leaked on the silk screen, and then use wheels to spray paint on the product across the silk screen. This is a commonly used advertising method in the advertising gift customization industry. Its advantages are low cost, simple production process, and wide application range; Its disadvantage is that silk screen printing belongs to monochrome printing, and a set of advertising content with multiple colors often requires multiple processing processes.
The basic principle of laser marking is that a high-energy continuous laser beam is generated by a laser generator. When the laser acts on the substrate material, the atoms in the ground state transition to a higher energy state; Atoms in higher energy states are unstable and quickly return to the ground state. When an atom returns to the ground state, it releases additional energy in the form of photons or quanta, which is converted from light energy into heat energy, causing the surface material to instantly melt or even vaporize, forming a graphic and textual label. The advantages of laser marking are high marking accuracy and low cost; Its disadvantage is that there are few laser marking supporting factories in the gift industry, and some products made of certain materials cannot use this process.
