Screen Exposure Foam Blocks - A3 or A4
A Screen Exposure Foam Block, also known as an exposure pad or compression pad, is a specialised tool used during the Screen Exposure process. It serves a crucial function in ensuring proper contact and pressure between the Screen Mesh and the Transparency Film during exposure. The Foam Block helps achieve this by providing a soft and cushioned surface for the screen to rest on during exposure.
Screen Exposure Foam Blocks are available in various thicknesses and sizes to accommodate different screen sizes and exposure setups, ranging from A4, A3 and A3+. Choosing the appropriate foam block ensures a snug fit and optimal compression during the exposure process.
A4 Foam block: 33cm x 23cm
A3 Foam block: 43cm x 33cm
A3+ Foam block: 51cm x 42cm
All are 4cm thick.
