Today, when the fashionable products are getting more and more like us, various transfer technologies for making hand technology have also been developed, attracting many entrepreneurs and fashionable people. Transfer printing technology is a kind of special printing. It was widely used in various irregular porcelain, containers, textiles, product label printing and other fields, and has a very good prospect of shopping malls. In the meantime, the transfer technology that was known at the time was more than water transfer and thermal transfer. What is thermal transfer technology? What characteristics and uses does it have? What is the transfer operation and the needs of the mall? Below we comment on these questions one by one.
1. Introduction to thermal transfer technology
Transfer refers to a printing method that transfers the corresponding image on the intermediate carrier film to the substrate, and the transfer can be divided into water transfer, thermal transfer, and gas transfer depending on the selection pressure. , screen transfer, low temperature transfer, etc. In the meantime, thermal transfer is to use a thermal transfer ink (ie, hot forward ink) on a colorful inkjet paper (or hot forward inkjet printing paper) for portraits, scenery, and the like, or usually ink is printed on the thermal film. On the transfer paper, it is heated to a certain temperature in a few minutes by a thermal transfer heating device, and the color of the image on the paper is realistically transferred to a material such as porcelain, glass, metal, plastic, cotton textile and the like. Printing technology.
It can be seen that with the thermal transfer technology, even if the image is of a plurality of colors, since the thermal transfer operation is only a process, the customer can shorten the operation of printing the image and reduce the loss of the data (product) formed by the printing error. In other words, the use of thermal transfer film printing can multi-color images at a time, without overprinting, even with only a few simple devices can print realistic images, so that it greatly advances its application plan and end transfer Operated.
2. Classification of thermal transfer technology
Thermal transfer technology can be divided into thermal advance transfer and hot press transfer. Thermal forward transfer, also known as vapor phase thermal transfer, uses dye-based inks with advanced conditions to mirror portraits, landscapes, texts, etc. that need to be printed by lithographic printing, screen printing, and gravure printing. The reverse method is printed on the paper. Then, the printed paper is placed on the substrate, and the ink on the forward transfer paper is directly converted from the solid state to the gaseous state by heating (usually about 200 ° C) to transfer the image to the printing. On the object. In this process, the paper used for transfer is referred to as "forward transfer paper", and the forward transfer ink is mainly composed of a progressive dye and a binder.
The hot stamping uses a screen printing (also by gravure printing, etc.) to print the image on the thermal transfer paper or plastic, and then transfers the image to the substrate by heat and pressure. However, with the wide range of laser printers and inkjet printers, many small workshops use laser printers to print images directly on the transfer paper, perhaps by using inkjet printers to print the images on the usual printing paper. Then, it is copied onto the transfer paper by an electrostatic copying machine, and at the end, the graphic on the transfer paper is transferred to the substrate by heating and pressing. This is the digital thermal transfer technology that is now widely mentioned.
3. Make things and end the process
The thermal transfer technology can be widely applied to articles such as porcelain, glass, metal, plastic, cotton textiles, etc. However, since the thermal transfer is bound by the heated area and the shape of the object, objects with different areas and shapes are used. Usually need to use specific production things, the common thermal transfer production things at that time are mainly flat machine (hot press machine), baking machine, baking cup machine, etc., but after all, their production methods are based on the principle of thermal transfer. Therefore, the production process and process are similar, but the use of thermal transfer things is not the same. The following is an example of transferring a picture to a clothes using a tablet machine to illustrate the progress and flow of the thermal transfer production.
Step 1: Print the image through a colorful inkjet printer.
Step 2: the printed image is placed on one side first, and the initial transfer is performed after about 15 to 20 minutes. When transferring the printed image on the clothes, place the image face down, then adjust the time according to the transfer of the thermal transfer device (usually 20 seconds), and close the heating pad of the device. : Pure cotton T-shirt should spray a little deepening agent on the printing part before transfer, and then dry it and then carry out thermal transfer. The effect is to change the color of the ink by hot pressure and advance the beautiful effect of the ink on the clothes) .
Step 3: In order to avoid the clothes being too yellow and yellow, you can put a lining on the clothes and then transfer the heat. After the time of the thermal transfer device is alarmed, lift the heater chip, open the image paper, remove the clothes, and turn off the power of the device.
Step 4: the end of the clothes to cool down, stack the bag, you can end the entire thermal transfer production, made into a product.
4. The benefits of thermal transfer technology
Typically, with the aging and extensive technology, the price of thermal transfer printers has dropped significantly to the level that is generally acceptable to the general public. Today, BRADY's handheld thermal transfer label printer TLS2200 is also under 10,000 yuan. However, many people still don't know, and nowadays, with the reduction of printing consumables, direct printing is actually more expensive than the cost of printing.
Specifically, the benefits of heat transfer are mainly: it can be printed in a small amount and does not constitute waste, even if only one sheet can be used for printing. The use of bar code advantages, collaborative scanning guns, to reduce the cost of manual disposal time. You can print a variety of graphics on your own, depending on the company's logo and certification. You can print the serial number to find the product. You can connect to the company database data for quick data capture. It can be used in the production line to find products to avoid production. Can be used in warehouse processing to keep abreast of new inventory. Tickets or various receipts can be printed, fast and of higher quality. Labels that are resistant to high temperatures, corrosion, or sticking can be selected as needed. It can print very quickly and can reach a length of 375px per second. With the use of the cutter, it can be cut immediately and used for ticket ambition. Computer correction, print content and print results are not inferior to printing. Using the system integration solution, with the bar code label as the preface, all the processing systems such as purchasing, production, warehousing, logistics, and sales are improved.
5. Thermal transfer shopping mall needs to be analyzed
What are the advantages and disadvantages of thermal transfer technology compared with the water transfer at the time of the fashionable and mainstream? Specifically, the water transfer printing is produced in accordance with the activity and convenience, and is not bound by the area and shape of the object. Usually, special items and equipment are not required (only one piece of water transfer paper is needed), so it is applicable. The plan is more extensive, and the cost of the form is lower than that of the thermal transfer. It is suitable for home users and small workshops and fashionable jewelry stores.
Thermal transfer, because the image is heated, the image color of the product will be more robust than the water transfer, and it is not easy to fall off. It has corrosion resistance, impact resistance, aging resistance, wear resistance, high temperature resistance, fire resistance, and energy. Sticking to the characteristics of no discoloration for ten to several decades, the thermal transfer technology is particularly suitable for the use of electrical appliances, daily necessities, building materials and other objects that have special needs for image preservation.
For example, trademarks, barcodes, labels, etc. can be printed on the product using thermal transfer technology. It is also because thermal transfer technology has such advantages and disadvantages, so this technology is often favored and used by some jewelry stores, printing manufacturers, and building materials.
In terms of the needs of shopping malls, along with the continuous development of product economy, some manufacturers have higher and higher requirements for the trademarks, labels and packaging of their own products. For printing operations, the concept of printing is no longer the tradition we have in mind. The paper is printed. From our daily necessities to work tools, to telecommunications, decoration, technology and other products from all walks of life, we need more and more useful external packaging, and most of these packagings must be terminated by transfer. Therefore, the transfer operation has a wide and deep shopping space.
Although water transfer printing is characterized by its ease of use and cost, it will have a great advantage in the transfer operation. It is a delicate and fashionable product, but it is like high temperature and image preservation like electrical appliances and metal aluminum. On products with higher demand for time, the effect that thermal transfer can reach is that water transfer can not be compared, so thermal transfer technology will win with its low cost, strong image and long preservation time. Taking the proportion of its corresponding shopping malls, its shopping mall vision is still very wide, and it is not even lost to water transfer. Of course, water transfer and thermal transfer have their own advantages, and they can even complement each other. Therefore, brothers engaged in the transfer industry may wish to consider both.
