My Konica 6085 will run 450 gsmThanks for posting. I do think Konica has come a long way from emperon controllers. I don't have need for impose but would have loved a cheap embedded print controller. Im leaning to Fiery only because at resell time it will go for more even though for my purposes the KM controller would be a better option.
If C6100 could do 450 gsm regularly (Konicas were famous for being able to do more than they spec) I don't think I will ever upgrade and run this to the ground.
