Why does the PET Film return to oil after being placed for a period of time?DTF white ink has an ingredient we call humectant. Its function is to prevent print head clogging. The main ingredient of humectants is glycerin. Glycerin is a transparent, odorless, thick liquid. It can absorb moisture from the air. Therefore, glycerin is a good moisturizer. Glycerol is miscible with water and ethanol, and its aqueous solution is neutral. At the same time, glycerin does not react with other components in DTF White ink, thus affecting the quality of the ink. Because of its physical properties, glycerin cannot be dried. If the drying process is insufficient, glycerin will appear on the DTF transfer film after a period of time. And it will look greasy.Learn More2023-05-08 -
Sublimation printing and heat transfer printingThe Sublimation Process
Sublimation is a chemical process. In simple(r) terms, it is where a solid turns into a gas, immediately, without passing through the liquid stage in between. When questioning what is sublimation printing, it helps to realize that it refers to the dye itself. We also call this dye-sublimation, as it is the dye that changes state.Learn More2023-05-08 -

Causes and solutions of powder sticking to PET film1. Air humidity (reference value 40%-70%)
Air humidity mainly affects the powder sticking to the film during storage, printing, and powder shaking. There is no feedback that it has an impact on the pressing process.Learn More2023-05-04 -
UV machine printheads analysisInkjet technology utilizes tiny droplets of ink to facilitate direct printing without the device coming into contact with the printing surface. Because the technology supports non-contact printing, it can be applied to a variety of media and is now being introduced into a wide range of fields from general-purpose to industrial. The simple structure combining the inkjet print head with the scanning mechanism has the advantage of reducing equipment cost. In addition, because they do not require a printing plate, inkjet printers have the advantage of saving print setup time compared to traditional printing systems (such as screen printing) that require fixed print blocks or plates, etc.Learn More2023-05-04 -
Do UV printers emit radiation?One of the most commonly raised questions from people regarding UV printer is “Do UV printer emit radiation?”Before we can answer that, lets find out a little more about radiation. In physics, radiation is the emission or transmission of energy in the form of waves or particles through space or through a material medium. Almost everything emits radiation of one kind or another. Like many other questions phrased similarly. You are implying that radiation is dangerous. But the scientific fact is that there are different types of radiation and not all of them is harmful. Radiation can be low level like microwaves, which is called non-ionizing and high level such as cosmic radiation, which is ionizing radiation.The harmful one is the ionizing radiation.Learn More2023-05-04
