People who often use toy UV printers may find that some peculiar smell will be produced during the printing process of the printer. The worse the ink used, the stronger the smell will be. Let's discuss the source of the peculiar smell produced by toy UV printers below!

1、 The LED UV curing lamp of the equipment will produce slight ozone during irradiation. The taste is relatively light and the amount is small. Generally, it can not be smelled; If the taste is heavy, check whether the power of the lamp is too high and damaged, and solve it in time.

2、 When the LED lamp irradiates the material, on the one hand, the ink has a chemical reaction with the material surface to release the taste, on the other hand, the heat will damage the material surface. A small amount of materials will crack out relevant chemicals and produce pungent smell; According to the actual needs, reduce the irradiation power of the lamp, or wipe a layer of coating on the surface of the material.

3、 UV ink product itself contains certain odor, and some odor will be generated after curing, which is generally within a reasonable range. If the peculiar smell is too strong, check whether the ink is expired and inferior, and replace it with a new qualified ink.

4、 Without communication with the manufacturer, some users will add some additives and other auxiliary materials to the ink or material surface. These undetected liquids may also produce pungent smell. Do not mix commissioning ink, coating and other consumables at will to avoid damage to the equipment.

5、Substrates of different materials are affected by the environment, which will crack out relevant chemicals and produce pungent odor.
