Why can’t pictures produced by photo machines be placed outdoors?

The general accuracy of outdoor photo production is above 720DIP, the picture is fine, the color is bright and eye-catching, and it is suitable for the production of indoor small format advertising pictures. Its ink is a water-based dye, and the picture needs to be waterproofed. There is no sun protection when outdoors, and it will fade easily in the sun. As for outdoor oily photography, it is a new product that appeared many years after the inkjet photography appeared on the market. It combines the advantages of the above two and makes up for their respective shortcomings. It has high precision, is waterproof and sunproof, can be used indoors and outdoors, and the material is not restricted by water-based coatings.

The car body advertisements used in outdoor photo production are all printed with inkjet printers. The accuracy is low, the visual sense is too poor, and the effect is not ideal; while the accuracy of outdoor photos can reach the photo line, and the expressive power is very strong, especially Delicate skin or exquisite products can be printed very realistically, and small characters as small as 2mm can be clearly expressed. Therefore, outdoor photography is an irreplaceable production method for car body advertising. In the past, the light sheets for outdoor photo production were all printed with water-based photo machines, which had good accuracy. The color is good. But its disadvantage is that it is very easy to fade. Generally, due to long-term light exposure in supermarkets and shopping malls, the color of light box pictures will fade away in less than 3 months. There is also the fact that most water-based lamps are back-sprayed, and their effects with or without lighting are very different, so the effects are not uniform. Oil-based outdoor portraits use eco-solvent ink, which itself has anti-ultraviolet UV components. It can last for 2-3 years in the sun without fading, let alone the exposure to ordinary fluorescent lamps. The lamps made with it can be used all the time. , until your product is updated, the old pictures must be replaced. And it is a positive spray, so what you see is the effect of lighting.
