This is how to turn a 4-1/4 tile into something amazing.
First clean the tile with some alcohol. I use cheap nail polish. Making sure tile is completely dry, spray it completely Black with spray paint. Let it dry for several hours, the longer the better. Place tile on the honeycomb. Center tile with the cross hairs. Place cross hairs in the center of the tile. Click Auto Measure. Mark your processing area. Make sure the image is centered in the square. Frame tile, making sure its centered. Click Process. This is the settings I use on all my Black painted tiles. Enjoy
