Our plockmatic Morgana goes down to 5.5in tall by 4.25in wide but not sure if it’ll go smaller. Having said that if I I had a do over I would have spent more on a different machine.
Even at the 4.25in wide the face trim can leaves rubber marks on the final prints so we usually end up hand trimming from 5.5 to 4.25 on a guillotine if the book is too thick.
The number of shoddy bad parts that had to be replaced in the first year was high. Mostly just parts that were made too thin. The repair delay time and service on it was also high. We waited months frequently to get things diagnosed properly and repaired. To get a service plan was around $15k/year and Financially, we would have been better off to buy a more expensive machine.
