Ok, so I had started constructing a 40 tile Rubik's Magic a while ago. I am nearly done with the design.

However, I now encounter a problem: how do you print the images on both sides of the paper without them being misaligned?

There probably is a topic for this already, but I can't find it. Any help would be much appreciated as I have decided to do this for a school project!

Well when I made my Super Master Magic I just printed the tile designs on two separate pieces of paper and put them back-to-back inside the tiles.

If you have access to a double-sided colour laser printer, you just place the images in exactly the same position on two pages.

If you have a simple inkjet, you have to print one, reverse the sheet, and print the second image. However, this may not produce exactly aligned images due to the paper transport mechanism, especially if it is a cheap printer. If you use normal 80gsm paper, you might also get colour bleed-through from one side to the other, so use at least 120gsm paper.

Another method is to print the images side-by-side on a single page, score along the image join, and fold the sheet along the score line, being careful to align the edges of the images. To do this easily, cut along one edge of the images so you can make sure that edge matches exactly when you fold. You now glue the two images back-to-back (use something like 3M spray glue to avoid the paper "wrinkling") and cut out the shapes you need. You may not even have to use glue if you carefully plan the placement of the images, because the paper is held securely inside the Magic tiles.

You shouldn't need glue. I just print them separately, cut them out carefully, and stick them in. The string will force everything into alignment.

Ah okay...I was contemplating on sticking two separate pieces of paper together but just wondered if printing on both sides is hard.

Thanks for the advice. Also, can I ask if brochure paper is suitable?
