The PowerSquare is a beast!
I used to sell production gear for Konica Minolta. The PowerSquare that you're referring to (previously owned by Watkiss) is considered the top-of-the-line booklet maker that we could sell. Because it's so large and expensive, we didn't sell that many, but anyone who had it loved it. Watkiss is now owned by
Plockmatic (who also owns Morgana and Intec now), and it still has the highest sheet capacity of all the booklet makers they offer.
The unit can be put
inline with digital presses from most of the major brands, or you can purchase it in an
offline configuration. It maxes out at 56 signatures (224 pages), while the plockmatics most are referring to here max out at 35 or 50 signatures (140 or 200 pages), depending on the configuration you buy.
