Why are there size limits on how small or big my prints can be?

As a large-format print lab; there are production and transaction limitations due to time, material and equipment constraints. For example; some paper and canvas types do not come in the widest sizes that our equipment can print.
Pro Glossy Metallic Prints are availbable up to 45×120.
The smallest size print we mount on foamboard is 8×10, upt o 30×30. Larger size prints require the much more rigid Gatorboard option.
All print production work orders require a minimum transaction amount of $20.
