Question

what is known as brayers process

Answer 1

Brayers in the original sense were generally made of wood (though Southward refers to theirs being made of "wood or glass"). Later, rollers could be made of composition, vulcanized rubber, sponge, acrylic, polyurethane or leather. They are formed around a shaft or core and often attached to a wooden handle.
