Mark, thank you,
I found a supplier in the UK but wait for the shipment price. Given your experience this will not be the solution then, I already have the Innova IFA24 which being thinner cockles too but has a similar image quality compared to the old ML-R, slightly more texture. Better find a third party alternative then near 270 grams. Rauch's Mediajet Litho was proposed as a substitute but I guess it comes close to the IFA24 and is just 230 grams.
RC? Could you cut a 5 mm wide strip of say 6 cm long. Split in between the surfaces with a knife, put in a glass of hot water and pull the surfaces further apart, stretch each part to see whether it has any polymer barrier or even PE foil in between? Scratching the wet paper fiber off the splits with a nail does the same.
Another nice paper lost in transformation I guess. Checked Aardenburg-Imaging yesterday for the longest lasting tests (260 hrs) + best results and it is nice to see that the Canon Heavyweight Satin Photographic RC 300 gsm is the only and best RC paper in the top ranking but sad to know that it is no longer made. My hopes are on the Epson Proofing White Semi-Matte but that one is just at 20 hrs but scoring better within that period than the Canon HW. A slightly cooler variety like the Canon HW next to it and the RC side would have been covered for me.
Met vriendelijke groet, Ernst
