Mimeograph Lettering JNL is based on one of the numerous plastic lettering templates once manufactured by the A.B. Dick Company of Chicago and is available in both regular and oblique versions.
The mimeograph utilized a porous drum which inked the backside of a waxed stencil sheet. Unlike traditional stencils which have cut out areas that are directly inked or painted, a mimeo stencil has the area to be printed scratched away by removing the wax coating with a stylus.
The resulting image allows the ink from the drum to seep through the sheet and transfer to the blank paper.
As with a companion font (Mimeograph Template JNL), the character shapes follow the routed letters of the template, complete with rounded terminals. A previous font release [designed with flat terminals and some alternate characters] is available as Interoffice Memo JNL.
