The process for lasering onto granite is much like wood, acrylic, and other items. First we need a good quality JPEG image. Next we take that image to Photoshop and delete the background. Deleting the background is important because ifyou don't the picture gets a washed out look. (trust me images on granite look best with the background deleted) Next we upload it to our PhotoGrav software. To be honest here, PhotoGrav does a lot of the work and gets the image to where our laser can really bring out the "bling" as I like to say. If you are an engrave and you have never used PhotoGrav I highly suggest using it. Once PhotoGrav does its work it is ready for the laser.
I would give you exact speed and power setting if I could but there is an element of experamentation and If I told you and you tried it you would just be disappointed. Believe me when I say there is a bit of trial and error to find the sweet spot when laser engraving onto granite.
I have found that these make great anniversary gifts, pet memorials or wedding keepsakes! The best way to display them is with an easel on a bookshelf or mantle.
