I just received The Basic Principles of the Opening and Middle Game (Kiseido, 2014) and I couldn't help but notice that it is printed on a paper that is very white, quite different from the light yellow-ish paper I had come to expect from this publisher.
It is not very important, but I do find this white paper is not as easy on the eye as the light yellow one. Do you know if all Kiseido books are now printed on such paper?
