I firmly believe that it is a difficult problem for UV printing customers. In the traditional inkjet printing manufacturing industry, everyone has a lot of knowledge, such as general weak organic solvent inkjet printing, UV light curing machine printing ink printing, ink printing, thermal transfer technology, and pad printing.
All kinds of printing have advantages and disadvantages. The big problem with ink printing is that it requires plate making process, which is very inconvenient and high in cost. The thermal transfer process very easy to causes damage to some products; weak organic solvent inkjet printing Although printing is a popular inkjet printing method at this stage, there are still some difficulties in adapting printing materials; UV printing can be said to be an all-round printing method in inkjet printing on the market at this stage, adapting to different raw material printing materials UV printing can be applied to different industries. However, UV printing can cause some odors in specific packaging printing, and the worse the ink, the stronger the smell, especially in an office where natural ventilation is not good. In the environment, it is very significant. What is going on?
For UV printing, the odor is usually caused by ink, such as UV ultraviolet solid ink, organic solvent, or weakly water-soluble resin ink, because the organic chemical composition of ink production is different, UV printing The irritating taste of ink mainly comes from its own raw materials, such as single paint thinner, low molecular weight initiator, epoxy resin interconnecting agent, etc.; under certain standards, the stimulating taste can be released slowly; it is very fake UV ink printing. Low-carbon and environmentally friendly production and processing regulations can be achieved. Therefore, in the UV printing process, the volatile organic compounds released from the left and right of the UV printing ink before and after curing will cause some smell.
In addition to the ink, another factor that may contribute to the bad smell during UV printing is the UV curing process itself. During the curing process, the UV lamp emits high-intensity ultraviolet light that activates the photoinitiator in the ink, causing it to solidify and adhere to the substrate. This process can generate a strong odor due to the release of volatile organic compounds (VOCs) from the ink.
To minimize the odor during UV printing, it is important to use high-quality, low-VOC ink and operate the UV printer in a well-ventilated area. Some printers also come equipped with air purification systems to help remove any odors or fumes emitted during the printing process. It is also important to follow proper safety protocols when using UV printers, including wearing protective gear such as gloves and a respirator if necessary.
