Letterpress printing uses a reversed, raised image
to produce the prints. Anyone who has produced
‘potato prints’ as a child will understand that the raised surface can be inked and then pressed
into a sheet of paper to obtain a right-reading image.


The type is made of lead or wood and line images were traditionally produced in copper or zinc but are now made from photopolymer plastic.




To print on our presses the image must be at
type height which is 0.918 inch or 23.32mm.





Smaller point sizes of type and small Line blocks need to be locked in a metal frame, known as a chase, when the whole image to be printed is known as a forme.




Larger type may be placed directly
on the bed of the press and can be held in place by strong magnets.
