The tri light will be better. You're not missing out!
This old amergraph barley fits a 23 x 31. Better for manual screens, less blanket wear.
Its a good unit, but is 90s era and has seen better days. It is perfect for a small manual shop on a budget that wants to do good halftones. If you have options, I would not recommend amergraph to anyone solely because of their proprietary blanket system with the hook latch BS which forces you to buy blankets from them.
