Some samples of Claria black only test targets are going into light fade testing by the end of this month at AaI&A. I'd hoped to have them in test sooner, but need to work out some pre-humidification experiments that will attempt to separate out any possible dye diffusion issues from light-induced fading. Dyes continue to migrate for a long time after printing, sometimes subtly changing the print density values. It's not enough for the typical consumer to notice, but the AaI&A Conservation Display ratings are a tougher criteria for "little or no noticeable" fade, so I want to have as stable a colorimetric starting point as possible in the upcoming tests.
