Over on the Luminous Landscape forum (a forum I choose not to participate in) there’s a thread about recent changes to Canson Rag Photographique. John Dean in particular has reported some worrying findings:
There’s a special on Canson in this country but ending very soon, and I was about to stock up on CRP anyway, esp at sale prices, but these reports stopped me in my tracks. I couldn’t get any sense out of the local suppliers, so I bought one pack and did some testing. The paper packaging is subtly different, and doesn’t say “Made in France” on the back any more.
I can’t replicate John Dean’s results - I didn’t get any blotchiness at all when printing images with deep shadows and areas of pure black, unlike in the EEF fiasco a couple of years ago. But I did find some changes. Prints on the paper, both colour and QTR, are modestly but noticeably warmer than on the old stock using existing ICCs and QTR curves. Neutrals are now slightly warm Moreover, QTR curves that were linear no longer are, and I’m getting a darker dmax.
For colour work I assume I could re-profile, but for Piezo there would be a change in the toning of the prints.
I’m still running tests, but if I’m going to take advantage of the sale then I’ll have to jump in the next 24 hours. Has anyone else had experience with recent batches of CRP?
