Polycarbonate: This material is flexible allowing for easier (cheaper) shipping and storage. Available in two different thicknesses .062" and .093".
The thinner material (.062") is less likely to to absorb excess pressure under heavy applications.
Polycarbonate will not crack under pressure like acrylic will.
The drawback is under heavy pressures polycarbonate will become slightly spongy causing a pressure loss on the press. Due to this we do not recommend it for uses such as Aqua Tint, Mezzo Tint or Photo Gravure.
(Note: Most printmakers never notice the difference under heavy pressure.)
Acrylic: This material is not as durable as polycarbonate. Recommended for use with heavy pressure applications.
(Due to shipping restrictions this item is only available by ordering over the phone)
Only one end needs to be taped for this to work. Over time the press bed cover will natuarally begin to lay flat in relation to the press bed and the tape will no longer be required.
