With the development of society and the continuous improvement of living standards, people are no longer satisfied with the pursuit of material things, but pursue higher goals, which also promotes the development of many industries.Be like the pursuit of fashionable beauty, handicraft gets everybody's love with each passing day, all sorts of transfer printing technology that USES at manufacturing handicraft also is come out subsequently by research and development, attracted many entrepreneur and fashionable love beautiful gens to use.Transfer printing technology is a kind of special printing, widely used in various irregular porcelain, containers, textiles, commodity label printing and other fields, has a very good market prospects.Among them, at present the most known transfer technology than water transfer and heat transfer these two, what is heat transfer technology?What are its functions and effects?What is the heat transfer method and market demand?Now let's analyze:
1. Introduction to heat transfer technology
Transfer printing refers to the medium carrier film on the text and text with the corresponding pressure transfer to substrate on a printing method, and according to the use of pressure is not the same, transfer printing can be divided into water transfer, heat transfer, gas transfer, screen transfer, low temperature transfer and so on.Among them, the heat transfer by any such as portrait, landscape painting progress (i.e. thermal ink) using thermal transfer ink printed on a color ink-jet paper advances dedicated inkjet printing paper (or hot), or the ordinary ink to print on the film thermal transfer paper, through the thermal transfer machine heat heating equipment in a few minutes to a certain temperature, the paper of the vivid picture to transfer to porcelain, glass, metal, plastic, raw materials such as cotton fabric on a special printing process.
It can be seen that the application of heat transfer technology, even if it is a multi-color picture, because heat transfer is only a process, so the customer can shorten the printing picture work, reduce the loss of materials (finished products) caused by printing errors.In other words, the use of heat transfer printing film can be multi - color picture at one time into a picture, no need for color, even if only a few brief equipment can be printed out of a realistic picture, so that it will greatly improve the scope of application and achieve the transfer of the operation.
2. Classification of heat transfer technology
Thermal transfer technology can be divided into thermal progress transfer and thermal pressure transfer.Thermal transfer printing is also known as gas phase thermal transfer, is the use of the dye type with progress conditions, after lithography printing, screen printing, gravure printing and other methods will be portrait, landscape, text and other images need to be printed on the paper image inversion method.Then printed on the paper on the substrate, after heating (generally about 200℃) pressure method to make progress transfer paper ink directly from solid state into gas, so that the image and text transfer to the substrate.In this process, the paper used for transfer is called "progressive transfer paper", and progressive transfer ink mainly consists of progressive dyes and binders.
Thermal transfer printing screen printing (also can use gravure, etc.) method will be printed on thermal transfer paper or plastic, and then after heating and pressure will be transferred to the substrate.With the popularity of laser printers and inkjet printers, however, many small workshops with laser printer will make good with a computer graphic print directly on the transfer paper, or with inkjet printer by printing on normal printing paper, and then use electrostatic copy machine on the transfer paper, finally, the graphic on the transfer paper after heating pressure method of transfer printing on substrates.This is now widely referred to as the digital thermal transfer technology.
3. Manufacturing and implementation processes
Using thermal transfer technology can be widely suitable for porcelain, glass, metal, plastics, raw materials such as cotton fabric, but due to the thermal transfer constraints by the heated area, object shape, so about different area, the shape of the objects are often required to make things, using a specific current common thermal transfer make things are tablet (pyrograph machine), baking machine, baking cup machine, and so on, but after all, their manufacturing method are based on the principle of thermal transfer, so the manufacturing steps and process are same, just used thermal transfer of things is not the same.The following to use a flat plate transfer picture to clothing as an example, explain the heat transfer manufacturing steps and procedures.
In terms of market demand, manufacturers' departments have increased their demand for the appearance of their products' trademarks, volume labels and packages. As for the printing profession, the concept of printing is no longer the traditional paper printing as people think.From our daily necessities to office appliances, to telecommunications, decoration, craft and other products of all walks of life, all need more and better and more useful external packaging, and most of these packaging rely on heat transfer to achieve, so heat transfer profession has a very broad and deep market space.
