While in research mode for a solvent printer, I did purchase a series of reports from FLAAR. For the most part, the reports aren’t really that useful. What you’ll get is ramblings about printers viewed at tradeshows and a few comments that are second hand. FLAAR, at the time I purchased my reports, wasn’t actually testing any of the solvent printers. You’ll find phrases like “word on the street” peppered through a lot of their premium reports.
FWIW, I think you’ll do better here asking about these machines and their performance.
Good luck.
