What is letterpress plate?

Ok, So What’s a Photopolymer Plate? 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.

How do you make a photo polymer plate?

  1. Step 1: Prepare the 60 Watt lamp.
  2. Step 2: Assemble liquid photopolymer packet and.
  3. Step 3: Two minute hardening.
  4. Step 4: 10 minute hardening.
  5. Step 5: Cut around the liquid photopolymer packet.
  6. Step 6: Wash all the liquid gel from the.
  7. Step 7: Final hardening process.
  8. Step 8: Dry your photopolymer plate and attach it.

Does letterpress use relief plates?

The plates of wood cut, wood engraving, linoleum block, and photoengraving can also be used in letterpress printing. Their raised surfaces can print photographs and illustrations as well as letters and numbers. Relief or letterpress printing is the oldest printing method.

What are polymer plates?

What are polymer plates and how do they work for letterpress? 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.

How letterpress plates are made?

Polymer plates are produced using a photographic process. The digital design is output to a film as a negative (left), and then exposed to a polymer plate using UV light (right). The polymer plate is made of a light-sensitive, water-soluble plastic with a clear backing.

Why is letterpress so expensive?

The answer is pretty simple: scarcity. When letterpress was the standard way of printing, there were letterpress presses and skilled operators everywhere. Then offset printing outpaced the quality and speed of letterpress and, by 1985, the last heidelberg windmill (my press of choice) rolled off the production floor.

What are flexographic plates made of?

Originally, flexo plates were made from rubber, but are today made from photopolymer material in sheet form – which differentiates them from the fixed metallic printing plates of offset printing. The plates are flexible enough to be wrapped around cylindrical print/plate rollers.

What is the difference between a polymer and a plastic?

Polymers can exist organically or be created synthetically, and consist of chains of joined individual molecules or monomers. Plastics are a type of polymer composed of chains of polymers which can be partially organic or fully synthetic.
