When dealing with HP Vivera inks, or maybe just with looking at them in a store, chances are youve seen something on the packaging that states that they are the best when it comes to resisting the light-fade effect that happens to a lot of photos that are printed through a printer at home. Light-fade is simply when prolonged exposure to either natural or artificial light slowly causes the ink to fade and therefore the picture to fade along with it.
HP claims that their Vivera inks are able to withstand this light-fade effect and that pictures printed with the photos will last for a century. If you follow the link that they provide in support of this claim, you will see a study done by Wilhelm Research; a light-fade experiment. This experiment did indeed show the results that HP discusses on the packaging of Vivera inks; namely that they last a very long time and are extremely resistant to light-fade.
Why exactly is this something that is unique to Vivera inks? Well, in order to discover that, you need to go a bit deeper and take a look at the science behind the ink mixing that goes into Vivera inks and how that science specifically related to the phenomenon known...
