Does letterpress use relief plates?
In practice, letterpress also includes other forms of relief printing with printing presses, such as wood engravings, photo-etched zinc “cuts” (plates), and linoleum blocks, which can be used alongside metal type, or wood type in a single operation, as well as stereotypes and electrotypes of type and blocks.
What are letterpress plates?
Letterpress Printing Designs are created on a computer then made into photopolymer plates for printing. A film negative is printed of your design in reverse, and then exposed on a light sensitive photopolymer. This letterpress plate is like a stamp and each color in a design requires a separate plate.
What are letterpress plates made of?
polymer
The polymer plate is made of a light-sensitive, water-soluble plastic with a clear backing. The portions of the plate that are exposed through the clear parts of the film hardens, and what is not washes away. What remains is a raised surface in the shape of the design.
What is letterpress printing used for?

How does letterpress printing work?
letterpress printing, also called Relief Printing, or Typographic Printing, in commercial printing, process by which many copies of an image are produced by repeated direct impression of an inked, raised surface against sheets or a continuous roll of paper.
What is a photopolymer plate?
Photopolymer is photosensitive material in sheet form that is exposed to UV lights through a negative film. The light shines through the clear sections of the film and hardens the polymer. The plate is washed out with water. The plate is dried and exposed to UV one more time to complete the process.
What are photopolymer printing plates?
Simply put, a photopolymer plate is a sheet of polymer with one side that is light sensitive. The digitally created design is transferred to a photo negative that is placed on top of the sheet of polymer. It is then exposed to light in a controlled exposing unit.
