Thank you all for your kind help! I Will have to take a look for this medium. Couple of days ago I coated my first successfull Gelatin layers to Inkjet paper. First I rubbed off the ink intake layer with hot water. Under that soluble layer, reveals nice smooth layer of "plasticied" coating. Much faster to prepare than using Resin coated silver gelatin paper and fiddling with fixer & long wash times.
Professionals make it look easy when thay coat the support sheet, it took me 3 nights to get the coating succesffull testing various methods :0)
