This is an easy way to enhance the look of your laser engraved sign using transfer tape and spray paint. The transfer tape acts as a mask so that the whole piece can be laser etched, spray painted, the mask removed and the resulting image looks more professional.
This is much easier than trying to add paint into the laser engraved portions after the fact.
This instructable assumes you have an image you wish to engrave and already know how to use the laser at TechShop.
Step 1: Attaching the Transfer Tape
The first step is to cover your piece with the transfer tape. The transfer tape was purchased at a local hobby store.
In this example the wood we are using oak. Other woods such as alder are preferred but oak was chosen in this case. The transfer tape protective coating is peeled off and then the tape is applied to the piece. Start from the center and push out all the air bubbles. A good bond to the wood is essential for good results.
