I just went onto Silverprint's website www.silverprint.co.uk to see if they were listing the new Ilford developers and was saddened to find out that Kentmere have discontinued their Art Classic and Document Art range of papers. Apparently, they can no longer source the paper base. A real shame as they were unique. And they have just re-released Document Art as a double weight paper when the single weight paper base became unavailable.
That's all of Kentmere's Art range gone within the last year or so . The information is on Silverprint's News page.
