There are many logo processes used in custom backpack
, among which thermal transfer printing is a new type of logo printing process that is more popular nowadays. But many people don't know much about this new type of process, so today, I have compiled some related materials about thermal transfer printing, let's get to know it together. Thermal transfer printing (referred to as thermal transfer printing) is a special type of indirect transfer printing. It is an emerging printing process that has been introduced from abroad for more than 10 years. Thermal transfer printing uses special transfer printing paper or transfer printing film to print patterns first, and then transfer printing to the substrate. It is mostly used for ceramic decal printing, textile printing, commodity label printing, etc. Thermal transfer printing mainly includes thermal transfer printing, sublimation thermal transfer printing, deinking thermal transfer printing, flocking thermal transfer printing, thermal transfer printing and so on. 1. Hot-press transfer printing The hot-press transfer printing technology first uses screen printing, gravure printing and other printing methods to print graphics and text on thermal transfer printing paper or plastic film, and then transfer the graphics and text to the fabric by heating and pressing. , Leather and other items. 2. Sublimation thermal transfer printing The traditional sublimation thermal transfer printing refers to printing the sublimation transfer ink on paper (or plastic film) by screen printing, and overlaying the printed paper (or film) with the fabric. Heating, pressurizing or depressurizing, the dye on the paper (or film) is sublimated and transferred to the fabric in the gas phase. In addition to fabrics, it can also be transferred to ceramics, metals and other products. The main feature of the sublimation transfer technology is that the transferred image is bright in color, rich in layers, and the effect is comparable to printing. The difference from traditional printing is that the dye in the transfer ink is sublimated by heat, penetrates into the surface of the object, and forms a beautiful image after sublimation. Therefore, thermal transfer printing products are durable, and the image will not fall off, crack and fade. 3. Deinking thermal transfer printing Using paper or film as the carrier, printing with plastic ink, because there is a hot-melt binder in the ink, it is generally not printed with adhesive. During transfer printing, heating and pressurizing, after the ink layer is heated, the binder melts and bonds with the substrate. When the carrier is removed, the graphic ink layer can be separated from the carrier and transferred to the substrate. 4. Flocking heat transfer printing paper is used as a carrier. First, pre-coat a layer of hot melt adhesive on the paper, then flock on the glue surface, and then use hot melt ink on the flocking surface (in fact, it is a solution of hot melt Glue) printing graphics. 5. Thermal transfer printing Simply put, it is the process of transferring ink from the ribbon medium to paper or film with heat and pressure, mainly used for label printing. That is, when the label passes through the print head and pressure shaft of the printer, the ink is transferred to the label by heat and pressure. The pattern of thermal transfer printing is rich in layers, bright colors, ever-changing, small color difference, good reproducibility, can meet the requirements of pattern designers, and is suitable for mass production. Therefore, the thermal transfer printing process is getting deeper and deeper in the customization of backpacks. Favored by all customers.
