I need Problem marking a bitmap file on anodized aluminum. There seems to be a background square halo printing (the size of the file) as though either the laser is not turning off or the bitmap white regions are not zero. I am printing a logo in raster mode that is simple black curved lines on white background. I can adjust settings to avoid the problem on green anodized Al but not at all on black.
Do I need to pre-edit the file prior to bringing into EZCAD?
Thanks
Steve
