At present, as a personalized inkjet printing hot stamping, transfer paper's principle is to use its film to melt the ink inside at high temperature, and then melt it on the cloth. Achieve the effect of "transfer printing". Therefore, the bad transfer paper adhesive layer will slowly fall off after washing, leading to fading. This method of thermal transfer is the most common in China, and almost 95% of them are this method. This method has special requirements for fabrics, which must be Khmer or pure cotton. Many problems arise because customers are uncertain about the content, which leads to the effect error.
Knowing this principle, we know that this transfer printing is not water transfer printing or thermal transfer printing, and it is called hot offset printing in clothing printing industry. Although some people say that their experiment proves the existence of the watermark T-shirt transfer paper, and the effect is very good. In fact, after understanding the basic principle of water transfer printing and the common sense of inkjet printer ink, we will know whether this understanding is correct. Unless the ink such as weak solvent or resin is directly printed on clothes, no matter whether the ink of any inkjet printer is pigment ink or dye ink, it will fade under water washing. This is caused by ultraviolet rays in the sun, which has nothing to do with transfer paper, but only with ink. Inferior ink will fade quickly without adding any anti-ultraviolet agent, and high-quality ink will last for a long time, but if it is exposed to the sun for a long time, the fading speed will accelerate. Attachment: thermal transfer printing method for fabrics and garments:
A, offset printing (as mentioned above, it is also widely used in garment factories, which requires that the fabric must be pure cotton or Khmer material, and its transfer paper varies from 2 yuan-10 yuan, among which AW is widely used and the effect is good. The main problems existing in other transfer paper are: washed and faded for many times, and the image becomes blurred after being left for a period of time. Don't think that printing is really good;
B, silk screen printing (clothing factory uses it for many purposes, but it can't be personalized, which involves the cost of opening the board);
C, thermal transfer (using chemical fiber material, if it is pure cotton material, it is best to cooperate with some fixing agents);
D, direct printing is ok at present, but it is still in the experimental stage because of immature technology and expensive equipment. Some people in China have modified ordinary inkjet printers, which have many problems and are not recommended for commercial use.
E, laser transfer printing, the effect is very good, but only limited to pure cotton material, equipment consumables are expensive, and are rarely used at present. One equipment is nearly one million, covering a large area;
F, personalized finished pattern hot stamping (in fact, it is a kind of offset printing, which is printed in large quantities in advance by the other culture every quarter, and appropriately hollowed out, plus some reflective technologies, foaming, planting, ordinary and other technologies. At present, it is widely used, but the disadvantage is that personalized hot stamping cannot be realized, and you can only choose from the provided patterns. As a light-colored T-shirt printing: it can be printed with ordinary ink, and the picture quality is high, but the excess part of the picture should be trimmed, and the paper quality must be good. After the transfer, the picture should be bright and clean, and the color will not fade after 24 hours of cleaning, and the feel is good. However, thermal sublimation ink has many solid layers and needs to be reversed. The difference is that it is suitable for cotton, but the feel of ordinary ink is not as good as that of thermal sublimation ink, and the poor paper quality is easy to fade. What about dark colors? You can also print with ordinary ink. The picture quality is high, and the picture does not need to be printed backwards. Suitable for all kinds of fabrics. Similar to high elastic hot stamping, but the rubber edge needs trimming, which can be comparable to high elastic hot stamping. Its advantage is that it is convenient without plate making, but the cost is high. Moreover, if the quality is not good, it is prone to fading, smoking, peeling, washing resistance, firmness, hard and thick feel and irremovable.
