Over the last 5 years I have often searched for a lower priced dual sided paper that could be used for books. Preferably near 150 gsm and opaque enough at that weight. Intelicoat had a 190 gsm on rolls that had no texture, OBA content, very white and quite rigid: DMPG190C2S. From another source I had a similar paper of 100 gsm. I bought some rolls but those qualities did not appeal to my customers. They preferred offset papers like Biotop 120 and 160 grams or the Munken weight equivalents, despite a lower print quality. Papers with some texture, warm white, flexible and low cost. Innova filled that gap lately with their Decor Art IFA25 dual sided. However 210 gsm and it could be a bit warmer. I still think that there is a market niche for a similar paper at 150 gsm. Possible sources: the paper qualities that are now developed and manufactured for inkjet web presses which are unavailable for small print shop owners: rolls too large and different distribution chain. Mondi the Austrian Biotop manufacturer has some qualities in that category, Felix Schoeller probably too and there are more manufacturers. A Biotop paper base withstands time very well, the more when used in books. No need for a buffered rag paper quality in that case.
Whether that product would go through your Museo or other Intelicoat channels is not something I can jufge.
In the art paper category, rag - alpha cellulose, 180 to 230 gsm there are several distributors of dual sided paper. Sheets mainly. Innova, Moab, Red River, Hahnemühle, etc. Their papers overlap one another in quality and the price range is covered well with Red River at the bottom. I wonder whether Intelicoat could create a financial success in that crowded category, a market niche itself.
In the art-photography industry the maximum sheet sizes of dual sided paper are at best aiming at 17" inkjet printers sometimes not even using their largest size capacity. I am using 44" roll printers and an A3 sheet printer and could use a size like 70x100 cm which gives me better economy on different sizes and a more flexible use of the grain direction. In house cutting. I would not object to dual sided rolls either. Printing the first side from the roll and have the sheets cut by the printer + tabs for registering the other side in sheet mode is quite easy and less labour intensive than doing sheet mode for both sides on those printers. At that paper weight an iPF5100 does not transport papers well from >15 sheets stacks either and I can put several pages on a 84x112 cm sheet so the advantages of a sheet loading tray are not that significant.
Just my thoughts and experiences.
