Ok, where does the true DPI number come from. I was using PhotoGrav to process an image. I load an image, select a material, then resize the image. Well when I go to resize the image was 130 DPI and some size. I changed the size and then changed the DPI to 300. When I engraved the image on a laser tile it looked great except every .5" I got a darker band about .125" wide. I then changed the DPI on the laser to 260DPI and it worked great no banding. Hey, I think I have this laser thing figured out.... I decide to do another image I look at the original DPI and it is 230 DPI, so I decide to laser engrave it at 460 DPI. I get banding, I the try 230 DPI I get banding. This image was processed same as the first at 300 DPI.
So I ask again, where is the correct place to get the DPI number. I can't keep burning up tile.
By the way the image on the laser tile looks really good.
Thanks for the help,
Bruce
