Heat transfer printing machine is also called heat transfer printing. Thermal transfer printing is an emerging printing process, which has been introduced to China from abroad for only more than 10 years. The hot stamping machine is one of the heat transfer printing machines, which can iron all kinds of hot paintings on cotton, linen, chemical fiber and other fabrics, and can also carry out screen printing, glue, foaming and other process heat treatment, suitable for making cultural shirts, etc., economical and practical, exquisite patterns. In this issue, we will summarize the advantages and disadvantages of comparing thermal transfer printing machines and hot stamping machines.
Heat transfer printing machine
Heat transfer printing machine is also called heat transfer printing. Thermal transfer printing is an emerging printing process, which has been introduced to China from abroad for only more than 10 years. The printing method is to first print the pigment on the paper, make transfer printing paper, and then transfer the color to the fabric by high temperature (heating and pressure on the back of the paper), generally used for chemical fiber fabrics, characterized by bright colors, delicate layers, realistic patterns, and strong artistry. Transfer printing process is simple, small investment, flexible production, currently popular in the market, heat transfer printing and other types of printing comparison, the price is a little higher, but there is a certain grade, chemical fiber fabrics need to use heat transfer printing 'method.
Advantages: simple printing steps, accurate position, natural transition between different colors.
Disadvantages: more colors will turn into color, and there will be blue dots, red dots and other problems in the printing process. Compared with traditional screen printing technology, the cost is higher when printing in large quantities.
Hot stamping machine
Hot stamping machine is one of the heat transfer printing machines, can be a variety of hot painting on cotton, linen, chemical fiber and other fabrics, but also screen printing, glue, foaming and other processes heat treatment, suitable for the production of cultural shirts, etc., economical and practical, exquisite patterns. It is replacing traditional embroidery and screen printing, while the cost and effect are much lower than and better than general embroidery and multi-color screen printing.
There are two kinds of ironing machines related to the clothing industry: flat ironing machines mainly used on clothing fabrics, and hat ironing machines with arcs for hats. According to the operating power, it can be divided into manual, pneumatic and hydraulic pressure.
There are three main concepts of ironing machine, which are pressure, temperature and time. Its working mechanism is to heat up through the heating plate, and use a certain pressure, specific temperature and time to bond the layer and thermosetting on the transfer paper to the substrate or penetrate into the substrate.
The core component of the hot stamping machine is the heating plate, so you should pay attention to it when choosing a hot stamping machine. The upper and lower plates should be made of aluminum, and the heating tube is cast inside the aluminum plate. If the upper plate is an aluminum plate slotted, and then attached to it with a heating tube, it will cause unnecessary energy loss, and there will be shortcomings such as slow heating and large constant temperature difference when used. If the lower plate is iron plate or other materials, long-term work in high temperature and high pressure environment, will be easy to deform and age. According to the area of the heating plate, the upper and lower plates have weight standards, if it is too light and too thin, the heating plate will be easy to deform, affecting the use. In general, the greater the weight, the more reliable the performance. After the upper plate of the ironing machine is pressed, it should be absolutely parallel to the lower plate. If the upper and lower board bite is tested whether it is tightly fitted, you can put a piece of hard paper or other sheet of tough material objects in the four corners, and then press the handle down, and after the upper and lower board bite is stuck, pull the hard paper piece outward to know whether the upper and lower boards are flat and whether the machine is qualified.
Advantages: no plate making, one piece printing; The image is realistic and can be close to the picture effect.
Disadvantages: slightly hard feeling; Light colors are very breathable, but dark colors are not breathable.
