Main menu
- Start to remove ink with a soft dry rag. If you are inking correctly, you should only have a thin layer of ink on the surface of your polymer plates.
- Wipe polymer plates down with a little mild solvent to remove the remaining ink.
- Wipe off your letterpress plates one last time with a dry rag.
How do you make a photopolymer sheet?

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 are polymer plates used for?
Photopolymer plates utilize coatings that provide more durable and abrasion-resistant image areas than do diazo coatings, and consequently photopolymer plates can be used for longer print runs (up to 250,000 impressions).
Can printing plates be reused?
The printing plate can be recycled repeatedly up to a cumulative total of 500,000 impressions at which performance deterioration occurs because of abrasion of anodized aluminum plate as a substrate.
How do you store print plates?
The printing plates should be stored in light-protective plastic bags or cardboard boxes to prevent absorption of additional moisture or drying out, as well as exposure to UV-light. If plates are stacked, put a cardboard interlayer between each plate to prevent them from sticking to each other.
How are letter press plates 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.
What is a Cyrel plate?
Cyrel® Coating & Varnish Plates are developed to provide a solution for printers and converters using varnishing and special effect ink and coatings applications.
Can photopolymer be recycled?
There is currently a United States patent (US 5552261 A) for recycling photopolymer by separating it from its supportive backing and then combining it with new photopolymer to be used in making new plates and other items.
How long do printing plates last?
5 to 8 years
From the perspective of time , usually printing plates will last 5 to 8 years depending on how they are cleaned (after use) and stored. To answer the question based on quantity, most printing plates will print 400,000 – 500,000 poly bags.
How are letterpress plates made?
How much do printing presses cost?
The starting price for a digital printing press can range from $5,000 to more than $250,000. Your price will depend on the size of the equipment, print speeds, and media applications.
