Laser engraving metal plates are manufactured with a finely polished metal, coated with an enamel paint made to be "burned off". At levels of 10 to 30 watts, excellent engravings are made as the enamel is removed quite cleanly.

To print a carborundum print, the surface is covered in ink, and then the surface is wiped clean with tarlatan cloth or newspaper, leaving ink only in the texture of the screen or carborundum. A damp piece of paper is placed on top, and the plate and paper are run through a printing press that, through pressure, transfers the ink from the ...
Matrices created by Jean Jannon around 1640. The Garamond typeface installed with most Microsoft software is based on these designs.
