Booklet with cover and text

[Kengel]

I'm trying to print a booklet with gloss cover and offset text and finish on the Plokmatic finisher. I get an error saying "Finishing (DFA Finisher) not supported by selected media (Plain Coated). It will print and finish if I print all on the text, but not if I choose a different stock for the cover.

Fold amount goes by the weight of the paper, so, if it's plain paper and 80GSM, the values are:

Pro 35 = 50 sheets

Pro 50 = 50 sheets

As soon as you increase the weight, the values drop, and Coated stocks reduce it greatly. They (Plockmatic) don't seem to quote the specs for anything but 80GSM uncoated.
