The AJ's versatility can be further enhanced with the optional MU Mesh Printing Unit for economical unlined mesh media. Custom engineered for the AJ, the MU is easy to attach and detach and features a built-in drainage system for easy removal of excess ink. Popular for a variety of indoor and outdoor applications, mesh is particularly well suited for graphics that may be exposed to excessive wind or any graphic calling for a unique sheer look. Unlined mesh offers many advantages over lined mesh including a lower cost per square meter. In addition, unlined mesh is easier to print, handle and transport, and it does not generate liner waste.
