A wick pad is dampened with electrolyte and placed on the stencil. The marker is rolled or rocked back and forth over the pad and stencil. A clear, sharp, permanent mark is produced in seconds.
The blank is cleaned, lubricated, and formed, after which the distortions of the circles are measured and proper interpretations made. Large areas can be gridded by moving the stencil in steps across the blank.
