Thanks jack but what i have been asking is are you talking about the DPI of the laser setting in lightburn or the DPI of the original artwork being imported. The DPI of the laser setting in Lightburn is 254 it has been 254 for every test i have done.
I have so far tried importing artworks created from 300 to 3600 DPI. If your saying that my original artwork should be produced at no greater DPI than the laser specification of 254 fine but please just confirm that thanks so we can put this to bed.
Best Regards Chris
