Back in the 1950s, if I lost the glasses that came with a 3D comic book, I could make my own with lollipop wrappers (cherry and grape — worked pretty well, actually). Many years later, when a local TV station broadcast “Creature from the Black Lagoon” in 3D, I made my own glasses (and those for several guests at a 3d TV party) from theatrical lighting gels. The gels are more readily available at stage lighting companies (check the Yellow Pages), are consistent in color and are reasonably priced.

Printing process is not important — good-quality color copies will work as well as printing, but the exact colors you use will probably have to be determined by trial and error. In my limited experience of goofing around with 3D drawing, I found that lighter shades or red and blue work better at “disappearing” when the appropriate gel is used.

Stefan Sagmeister did that trick on the cover of his book, didn’t he? I would think the inks need to be semi-transparent. It seem I have a book at home that has the english in red and the dutch in blue...or something like that. I’ll have to find that and check it out for you. Unless, of course, someone knows how at the moment.

It seems to me that the printer you have found that can do this would know which colors you should use. No?

he was very anal and would not give anything away... think it’s a bit of a secret! i will have a look at the book though, thanks.

Colored cellophane is easy to find in craft stores now.

From what I remember of the cheap “magic window” stuff, all you need is a pure red for the obscuring pattern and a light cyan for the hidden print. Both should be screened if possible. That way, the eye doesn’t pick up telltale outlines because all it can see are dots.

How can i make hidden typographic messages ’red reveal’/’blue reveal’ for this any software or any trick. please suggest me ASAP.

Thanks
