Rigid plastic boards?
In general, I think natural materials are so much more appealing...unless you're a polymer chemist, maybe. ![]()
I'm not a plastic engineer, but I believe 64 sharply defined alternating colored squares in a rigid plastic board is not as easily manufacturable as one might think. I've recently seen poured resin boards that come close to what you are asking about. But not really.
Why rigid plastic? Acrylic sheet could easily be silk screened.
This is a foldable (not rollable) plastic board, but I haven't seen it in person. http://chessgamesshop.com/index.php?c=21&p=111134
This one has even more, again, I've only seen them on the website:

Staunton Castle makes wood "look" boards. I don't know what they are made of but they are quite substantial. A padauk SC board came with the first set I ordered. The bottom is covered in felt. The boards are not cheap and SC just went up in price but SC is currently offering a 20% discount at checkout. You can see better photos here SC Board and here Tale of Two Boards SC states that the boards will not warp and are not subject to damage from water spills.
