Sublimation. What is it? Features and equipment

In recent years become popular Souvenirs with individually printed images. Such a process is called "sublimation". What is it? Response - technology that allows you to apply different objects vivid images which are resistant to rubbing, fading.

There are a number of requirements of fabric on which is printed the image. First, the color of the product. It needs to be pure white. Secondly, the fabric must present more than 60% of synthetic fibers. All of this is important to ensure that the material was resistant to high temperatures (more than two hundred degrees).

Let's take a closer look at this innovation as sublimation. What is it? The modern technology. Its essence consists in the following: image is applied to the fabric in two stages. On the ground it is printed on paper, and then thermal transfer is carried out directly on the item of clothing or fabric. If we consider this process more deeply, it is based on the disclosure of the polyester molecules, which occurs at temperatures over 160 ⁰C.

Special ink is applied to the image on the transfer paper. Then the printed image is superimposed on the material and placed under the press. There develops a high pressure, and the temperature reaches 200 degrees. The creation of such conditions leads to the fact that when heated, the ink stick to the paper disclosed previously molecules. Thanks to the transfer of the images takes only 30 seconds. When the product cooled down, the polyester molecule is closed again, and the paint stays inside. 

It is for this reason durable sublimation. What is it? Myth or truth? It really is not washed in any temperature, do not fade. The product can be ironed. This process has one significant drawback – shirts for sublimation must be exclusively white. If things are bright colors, then a good result can be guaranteed in the case of printing with black ink only. The same principle applies when applying images on mug, logos or other Souvenirs. The figure under the action of high pressure and temperature to bake the product.

Printer for sublimation

This is the basic equipment required for the production of Souvenirs in this way. If without a press and paper is something you can do, no printer – nothing. World manufacturers of computer equipment offer a wide variety of inkjet devices designed to technology such as sublimation. What is it and what brand to choose? Roland, Mimaki and many other brands have a high degree of print quality and reliability. Their essential disadvantage is the high price level that makes it impossible for the printer a budding entrepreneur. In this case, you can look for cheaper options among home or office devices. The main criterion of choice – the presence of the piezoelectric printing method. It is used in all models of Epson. In such print heads is made an impact on the ink. The drawing of the image should be bright, clear. This is provided by four cartridges. In addition, it is important to pay attention to the size of the droplets, it should be minimal.
