The CANON Pro Printer series 9500MKII PRO-1-10-100 have always had the little problem that is printing on regular matte paper setting using Photo Black instead of Matte Black like other printers. Only the fine art paper setting using Matte Fine Papers will allow you to print with Matte Black. But then you are forced to use a 30mm wide border all around. So does printing with either MK or PK ink make a huge difference on most MATTE Papers? -~-~~-~~~-~~-~- Please watch: "EPSON P800 Chip Decoder unfortunately DID NOT WORK!" https://www.youtube.com/watch?v=RWZiqDMwqv8 -~-~~-~~~-~~-~-
