Recently, souvenirs with individually printed images have become popular. This process is called sublimation. What's this? The answer is a technology that allows you to apply bright patterns to a variety of objects that are resistant to wiping, fading.
There are a number of requirements for the fabric on which the image is to be printed. First, the color of the product. It must be completely white. Secondly, more than 60% of synthetic fibers must be present in the composition of the fabric. All this is important in order for the material to be resistant to high temperatures (more than two hundred degrees).
Let's take a closer look at such an innovation as sublimation. What's this? Modern technology. Its essence is as follows: the picture is applied to the fabric in two stages. At first, it is printed on paper, and only then thermal transfer is carried out directly on the garment or fabric. If we consider this process more deeply, then it is based on the opening of the polyester molecule, which occurs at a temperature of more than 160 0С.
Special ink puts the image on the transfer paper. Then the printed image is superimposed on the material and placed under the press. High pressure develops there, and the temperature reaches 200 degrees. The creation of such conditions leads to the fact that when the paper is heated, the ink adheres to the previously disclosed molecules. Thanks to this, it takes only 30 seconds to transfer the image. When the product cools, the polyester molecule closes again, and the paint remains inside.
It is for this reason that sublimation is durable. What's this? Myth or truth? It actually does not wash at any temperature, does not fade. The product can be ironed. This process has one significant disadvantage - sublimation T-shirts must be exclusively white. If things are light shades, then a good result can be guaranteed if printed only with black ink. The same principle is followed when applying the image to a mug, logos or other souvenirs. Drawing under the action of high pressure and temperature is baked to the product.
Sublimation Printer
This is the basic equipment needed to produce souvenirs in this way. If you can somehow do without a press and paper, then you can’t do without a printer. World manufacturers of computer equipment offer a wide range of inkjet devices designed for technology such as sublimation. What is it and what brand to choose? Roland, Mimaki and many other brands are known for their high print quality and reliability. Their main drawback is the high price level, which makesit is impossible for a novice entrepreneur to purchase a printer. In this case, you can look for cheaper options among home or office devices. The main selection criterion is the presence of a piezoelectric printing method. It is used in all Epson models. These printheads do not affect the ink. The printed image must be bright and clear. This is provided by four cartridges. In addition, it is important to pay attention to the size of the drop, it should be minimal.
