Print the image* on your printer with matte photo paper.
Cut it out the label.
Using a black permanent marker, carefully color the edge of the label.
Lay the label down face up, and place a strip of clear shipping/packing tape sticky side down onto the label. Press gently across the top of the label to smooth out any bubbles or air gaps.
Cut out the label from the packing tape.
Using temporary or permanent double-sided tape, place the tape onto the label, and then place the sticker onto the 2x4 tile.
* I supply a PDF and PNG version of each model's label. If you want to print multiple at once to save on paper, you will have to resize the images on a Word / Pages document. The exact dimensions of a 2 x 4 tile is 1.22” x 0.6”, so you can use that to resize.
Sticker Paper
If you want a little shortcut, I would highly recommend this sticker paper from Amazon. However, I still strongly recommend using the above method of packing tape to protect the sticker, even after printing it on specialized sticker paper. This will prevent ink from rubbing off and scratches from forming on the easily-scratched surface of the glossy paper!
