The weather resistance time of images printed by UV machines for outdoor use varies due to various factors, such as climate environment, material quality, UV ink quality, spray printing technology, etc.
Firstly, environmental factors. If the outdoor environment is harsh, such as low temperatures, high temperatures, direct sunlight, wind and rain, etc., it may result in a shelf life of less than 2 years. On the contrary, if placed in an environment that avoids direct sunlight, has a suitable temperature, and has a small temperature difference, its weather resistance will be extended several times. If it is an indoor environment, its weather resistance can achieve permanent non fading;
Second, high-quality UV ink usually has good characteristics such as UV resistance, humidity, and high temperature, and harmful substances such as VOC and toluene have low values, which can provide good protection for the weather resistance of UV printed products. So, choosing high-quality ink can also increase the weather resistance of the image. High quality UV ink printed images can be guaranteed for 8-10 years outdoors; The cheaper the ink, the shorter the weather resistance time;
In addition, selecting materials with good weather resistance such as polyester film, PVC, and acrylic board during printing is equivalent to adding double safety to outdoor images; At the same time, if high requirements are placed on weather resistance, post-processing techniques such as adding varnish or laminating can be adopted to improve the outdoor storage time of the pattern, usually extending its lifespan by twice;
In order to extend the service life of UV printer products, we recommend you choose high-quality materials and ink, and pay attention to protective measures, such as regular cleaning, avoiding direct sunlight and damage, and taking necessary maintenance work.
