I’ve been listening to the 12 podcasts today and they are an easy to understand ( to your clients ) resource.
The last one #12 was the most interesting and valuable to me. It describes all the years of testing protocol that led to the understanding of Light Induced Low Exposure print staining. This is what happens when prints that have previously been exposed to light are placed in dark storage and begin to yellow in a way not seen before they were put in dark storage. I’ve seen this with some of my own rc media in a flat file, and didn’t know what was causing it.
By the way this will occur with all rc papers on the market today analogue and digital, to some degree, and a lot of the so called “ Baryta “ papers that also contain a combination of dye brighteners and titanium dioxide white pigments.
Good news is there are some pigments that don’t show this and of course many great papers that have no pigments or dyes added . This it seems to me is a huge area for possible study, getting rid of all the dye brighteners once and for all and find new durable substitutes that are stable.
I hope every paper manufacturer in the world listens to this podcast because if they don’t, it will most definitely come back to bite them in a big way.
