subject: How Long To Keep Outdoor Inkjet Image Quality - Outdoor, Advertising, Printing - Silk Screen [print this page] When your guests see you play after the sample, happily praise the bright colors and happy to hear you say can be delivered within 24 hours. Then, he may want you to immediately spray a 6-foot-x10-foot posters, and hung in the smoke billowing in the industrial area. Just think of the image exposure, or rain-fed every day by the evening there will be graffiti or who visit, it sounds very Zhajing, how that image really can be hung long?
If you want the best image to keep the longest, we must first know ourselves and understand prevent the enemy image. That in the end that is harmful to the image of things?
Number one enemy - the sun
Ultraviolet (UV) is the image number-one killer, especially Inkjet Image, an unprotected Dye (DYE) Ink Inkjet image less than a day in the sun will fade against ultraviolet radiation, there are three options:
Use good quality ink and substrate, if possible, use Pigment Ink.
Coated with a UV laminate. Choose where no direct sunlight to wall charts. If this combination of three conditions
very good, you probably spray to save the image to an image replaced until we start talking about the ink, dye ink, the ink is the most common one is ultraviolet radiation very easy to crack and fade away: The Yen Section UV ink-woman was much better, the reasons are:
Pigment molecules are stacked particles, even if the UV destruction of some color, but the rest of the molecule is also able to maintain the color of the gloss.
Pigment molecules assembled in the lattice can absorb UV energy to destroy the color of the energy dispersion, Yan Branch ink is that it has this feature, so color and durability, but this feature is also Queshi image color hair dark and easily blocked nozzles. Over the years manufacturers have been under the ink stone grinding process work, and so these two issues has greatly improved, and there are many plant pigment ink, and dye products that can even match the color of ink. Pigment inks, such as with suitable substrate, it will greatly enhance the image performance, manufacturers have to match the ink and substrate chemical extreme, to more prominent image. Therefore, the purchase of pigment ink, the best choice they recommended pairing.
Emergence is less than pigment ink dye ink, because it is heavier particles. Pigment ink point is not open-so large dot pitch, ink spots sparse, the images look more mud. Yan is now used in grinding particles is 1.5 wavelength, in order to reduce the phenomenon of light dispersion and plug.
Another method is UV coated / laminated. Coated on the chemical or UV absorbers, they can extend the image life several times. UV-absorbent coating on a hit in before the image has become less than the heat dissipated open to the UV blocking agent is to be reflected ultraviolet radiation, which is mainly anti-blocking agent to be coated aging. The right combination of film and Adhesives The chemical composition is not an easy task, different combinations of UV protection in different wavelengths of radiation, different wavelengths of different colors of ink destroyed, and you can use without too much ultraviolet absorbent and reflective agent, because it makes the spray work out too dark.
When UV coated substrate is not to determine your next used fluorescence. Because the substrate with the optical brightening white media to increase the brightness, it re-absorption of ultraviolet ray reflection energy calibration substrate of yellow can make whitening. If your UV blocking coating such substrates fired ultraviolet rays, the image of the white area you will be slightly yellow, it is best not to listen to the recommendation of companies own match.
Final UV method is not to let direct sunlight as much as possible the image, especially when the image is attached to Glass Later, the accumulation of light and heat will further damage the image.
