Eco-solvent signage printers add color to the rapid development of the business, high-performance and high-precision inkjet printing with high performance,making outdoor photo inkjet applications more colorful and diverse in style.
However, for the long-term using of outdoor large format eco-solvent printer, the application environment, ultraviolet light, rain, dust, temperature and human factors are very important. Therefore, in order to make the outdoor inkjet photo longer, it is necessary to give better protection.
Everyone knows that ultraviolet light is the first factor in inkjet image printing, especially the image printed on the photo printer. An unprotected dye ink inkjet image will fade in less than one day in the sun; therefore, outdoor photo printing needs to use high quality. And UV-resistant weak solvent ink or oily ink, especially weak solvent ink, better environmentally friendly ink. There are three ways to deal with ultraviolet radiation: use good quality inks and outdoor inkjet media, use UV-resistant coatings, and use a place where there is no direct sunlight.
Long-term aging protection operation for outdoor photo printing:
1.Use high quality outdoor ink
Using the original solvent ink of the inkjet eco solvent printer manufacturer, the original ink color proofing is good, the inkjet printing image has small color difference and better use of fluency. At the same time, the ink is strictly tested by the manufacturer's inkjet printing. It is compatible with the machine, and the color of the picture is good. If it is outdoors, it is good with weak solvent ink, environmental protection and small smell.
2.Outdoor inkjet image film and glue
Outdoor inkjet image film and glue, chemical film on the protective film or UV absorber, which can extend the life of the image several times. Ultraviolet rays are applied to the absorbent on the film before it reaches the image, and the heat is dissipated. The UV-blocking agent reflects ultraviolet radiation. This anti-reflectant is mainly used to prevent aging of the film. Proper combination of the chemical composition of the film and the adhesive is not an easy task. Different combinations protect against different UV wavelengths of radiation, different wavelengths destroy different colors of ink, and you can't use too much UV absorber. And the reflector, because it will make the squirting work
too bleak.
3.Inkjet photo application environment protection
The protection of the application environment of outdoor inkjet printing is very important. Due to the complex and varied outdoor environment, there are many influencing factors, such as rain, dust, temperature and human factors, graffiti and scratches. Rain, moisture can wrinkle the image. The key to prevention is to pass the glue, and to ensure that the periphery is sealed when the glue is applied. Inkjet paper like the surface of the sea to absorb moisture, a little gap will cast a big mistake, especially in the cropping must pay attention to, because the moisture will spread the ink, thus destroying the quality of the image; outdoor inkjet photo application environment high and low temperature changes are also The enemy of beautiful images, high and low temperature images are always appearing under high temperature and zero temperature for too long, so pay special attention to handling. If the temperature is too low, the image will be cracked. If it is too hot, the image will be covered or peeled off, making the image unclear. It is recommended to choose high-quality outdoor media materials for better outdoor environment applications,so that the inkjet photo has a longer life.
The outdoor eco solvent printing machine uses a eco solvent oil type ink, which has a better application for outdoor photo printing. Outdoor eco solvent ink features: support better outdoor medium layer adhesion, ink waterproof and UV protection, pattern color can achieve long time without fading and lightening in outdoor environment applications.
