My grandmother had a small stack of 3-D comics in her basement, which I believe had originally belong to my uncle (her basement was like a museum), and this book was among them. So I enjoyed getting the opportunity years ago of reading 3-D comics in their original format – on paper! I remember in order to read 3-D comics with the least eyestrain, you needed a stronger source of light than an ordinary comic, since the glasses cut down on some of the light entering your eyes. With digital 3-D comics, I find wearing two pairs of 3-D glasses over one another works the best!
The fact that the red-only version reproduces darker than the blue version is based on a common principle – red photographs more strongly than light blue (cyan) does. In fact, printers sometimes make their proofing marks with a light blue pen or pencil because it is less likely to reproduce.
