I have a question. I got my first laser about a month ago. Epilog Helix 40watt. I am using Engravelab Photolaser plus software to deal with photos. As far as looking at back posts I am to page 146. This my first attempt at trying to put a picture on absolute black granite tile purchased at lowes ($4.98, 12" x 12"). There should be 2 photos attached. The image is the same size in both. On the granite, all 4 images were run at 300 dpi, 25 speed, and 100 power. All were run with the Stucci setting. Starting in the upper left the color photo was processed using engravelabs Granite high contrast.plr, The upper right was he granite.plr, the lower left was the Marble Invert 300DPI Epilog.plr and the lower right was with Marble.plr. The photo on the cherry was run at 600 DPI, 60 speed, 100 power using the Cherry hi detail.plr. I have had good luck using wood and mirrors. Although the photo of the images on the granite is terrible, so are the engravings. Any advice on how to improve? my thought is to do the same thing again with the same settings but convert the color photo to grayscale before doing the stuff listed above. Am I on the right track? Thanks.
