There have been many discussions on Longevity of inks. The question inevitably is asked regarding fade resistance, how your inks stand up to Epson’s for longevity.

I do apologize for not having a simple answer for you and or having used so-called expert testing, but here is information you need to know.

AIS only uses high rated pigments and pigment dispersions to produce UltraMaxII inkjet inks. The raw materials come from Germany and the US. I want to establish once again, AIS is an ink manufacturer, not a reseller or repackage as many of the companies you may be buying from are. Our greatest focus has been on the weak links of inks, Yellow and light inks. We do not use Epson’s favorite Yellow 74 which lacks in ongevity, but in its place we blend two longer life yellow pigments to create a bright non Green Yellow. Our UltraMaxII inks have been used for outdoor signage as well as Photo/Fine Art. AIS does not produce Epson clone inks. We are a unique manufacturer as we have created our own ink sets from 4 color to multichannel of 5,6,7,and 8 primary color inks. We also offer darker light inks and rip software to control the blending of light to dark ink. Darker light ink offer greater longevity, but result in more visible dot which is not ideal for small portrait prints. To help our clients we offers free custom profiling for all our ink systems whether with our rip or through Image Print or Photopshop.

Ink Longevity Testing

A significant method of testing ink longevity is to print on non OBA (optical brighteners ) acid free paper and place the test chart and images in an Atlas Light and Weather Chamber controlling the Light, Heat and Humidity. Most of the longevity tests conducted by third party people are using methods that do not include heat, humidity using a test chamber. In the real world heat, light, and humidity exist and play a role in activity. A test chamber is extremely expensive, but used by pigment manufacturers as the established way of testing inks. Their tests have made it possible for ink manufacturers to choose ideal pigments for color and longevity.

Past Mistakes

Cibachrome analog print material was given a life expectancy by Wilhelm for over a hundred years, however; with heat and humidity we showed it could be faded within less than a month.

AIS Pigment Quality

Quality raw pigment colors are rated for light fastness from 0 to 8 from material providers and the rating is based on the strength of the pigment loading and the sensitivity of the pigments to Ultraviolet Rays. Therefore, a pigment that actually has a high rating but used in lower amounts in an inkjet formula will result in a poorer resistance to ultraviolet light rays and consequently a pigment that has slightly less resistance to light being used in a greater degree will offer better results. AIS uses higher loading of its inks for greater dynamics on fine art papers which also has an advantage in light resistance.

Many of our clients have used our inks for signage, because of their high light resistance. Our software Rip aids in control of how we use light and dark inks.

In the next few months we expect to have chamber comparisons to satisfy your need to have test results.
