Follow these instructions and you'll be getting your first taste of Lumii 3D in no time.

1. What you'll need:

  1. The Lumii Holiday PDF (download just above).
  2. Print yourself:
    1. A printer, laser or inkjet, that can print on transparency materials.
    2. Transparency materials. See the FAQ on how to get them.
  3. Alternatively, if you can't get your hands on #2, you can may find a print shop near you willing to help (Make sure to tell them to not scale the pdf when printing. Also call ahead to ask if they do transparency printing and what the turnaround is - we got some puzzled looks at a Fedex until the more experienced staff did it for us.):
    1. The best print quality print was done by Staples at 600 dpi ($2.38+tax/sheet). Turnaround was 2 hours. Their transparencies are fairly thin, so make sure to add extra spacer sheets (see instructions below).
    2. At Fedex, we got slightly worse results than at Staples, but the quality at 600 dpi was still acceptable ($0.75+tax/sheet). Turnaround was 10 minutes, the resulting card may also look better with extra spacers added.
  4. Scissors and glue

2. Print On Transparency

Be sure to check the tips in the Printer Settings Tips section before printing your Lumii Holiday PDF.

3. Cut It Out

Cut out the four rectangles along the dotted lines.

4. Stack IT

There are top and bottom sheets that must be placed on the top of the stack, closest to you, and on the bottom of the stack, furthest away from you, respectively. Look for the label in the top left corner of each sheet, and double check that you have them in the right order. The spacer sheets can be placed in any order in between the top and bottom sheets.

5. Align IT

Align the top and bottom layers in front of a light source like a window or screen. It's important to check that your printout works properly before you glue things together. If you're not seeing the 3D effect, or it doesn't look as good as it does in our video, check the Troubleshooting section below for some tips.

6. ADD Optional Spacers

The spacing between the top and bottom layers is optimized for a distance of 1/32 inch. As different transparencies vary in their thickness, you may need to adjust the number of spacers between the bottom and top layers. Adding more spacers will make the scene pop out more. You can download a printable sheet of spacers here for letter and here for A4, or just cut them to fit from a blank sheet.

7. Glue It

  • Place the bottom layer on a light colored surface that you wouldn't mind ruining with superglue. A piece of scrap printer paper works well for this purpose.
  • Place a small dot of superglue in each of the four circles.
  • Place the next layer on top so that the circles line up. You'll have five to ten seconds before the glue hardens to readjust the position of the layer you just placed.
  • Once you're happy with the position, let the glue dry for 30 seconds before repeating with the next spacer layer.
  • When you get to the top layer, check one last time that everything works before you place the glue.
  • If it takes you more than five seconds to align the layers, you may want to get things aligned first, and hold the layers together with paperclips or weights while you glue one dot at a time.
  • If you made a mistake, you can pretty easily pull the layers apart and try again.

8. View It Against A Light

The Lumii Holiday Card is 4 x 2.3 inches, which will fit nicely on most smartphone screens. You can load a blank page on your phone by clicking here, or typing about:blank into your browser's address bar. Your phone will provide a nice mobile backlight for your card! It will also look nice in a window or in front of a computer screen.

9. Get creative!

Add your own holiday cheer to your Lumii card! Can you make a better backlight for your card? Maybe a blinking webpage to add some color! What about a nice cardstock border?
