What is the difference between the MZX-UL 23″x31″ OD and M3-UL 23″x31″ OD frames?
The MZX-UL frame has a smaller roller diameter at 1 7/16 – inches and has a maximum tension capacity of 35 Newtons. It is more suitable for manual shops that need to print large images as well as the small auto shop that does small volume work. The M3-UL frame has a larger roller diameter at 1 5/8 – inches and has a maximum tension capacity of 85 Newtons. It is our “Automatic” frame and it is 300% stronger than the MZX model even if the printer chooses never to go above 40-45 Newtons. Although the MZX-UL can be used for automatic printing, we recommend the M3-UL for medium to large shops with multiple automatics who do not want any screen tension limitations.
