Hello Sanjay! The cheap deal I use that Earl spoke of is called a SMarT Measure. It's a depth measuring microscope that uses the same principle of measuring optical focus that the units from Vision Engineering do ( if you've ever looked at any

I do not use MPM printers but I find it hard to believe there would be a problem, assuming the MPM printer can be configured for Edge reference stencils. The double image stencil is basically two edge reference stencils in one. Assuming the art work

Hi Nancy! Just as Steve and Dean said, most printers have some sort of restrictions of what frame, where the image is positioned, ect. before the stencil will work in the printer. The two manufacturers that I'm most familiar with DEK and MPM do have
