How does NCR paper respond to doublebinding?
NCR paper is infamous for its bad binding quality with perfect binding technology. Doublebinding, on the other hand, yields absolutely superior results in every way. It is very important for self-carbonized paper books to lie open flat, since it is normally necessary to write fairly close to the actual binding. Left-handed persons usually have the hardest time writing in NCR books because the books don’t open as flat as they should. Doublebinding dispenses with this problem. • How does wrong graind binding affect doublebinding? The fibres that make up paper are allways aligned either along the length of the page, or along the width of the page. Binders normally take great care to ensure that the paper grain matches the binding of the book, otherwise the layflat quality and binding strength of the book may be severely compromised. Doublebinding is extremely forgiving regarding wrong grain binding. So far, tests have found that it doesn’t really matter if paper is bound against the grain
