If you wish Lightburn to not modify the original artwork, you use the passthrough option in the cut/layer edit window. This is used with output, such as Imag-R or other processed images when you don’t want Lightburn to change the created image.
If passthrough is not enabled, Lightburn will dither or make the dpi as the user has set within the cuts/layer window.
You are not using grayscale anywhere that I can see, so I think you mis-labled the name of this thread. Don’t know if it matters or not.
LED lasers do well with grayscale, fiber lasers don’t do well with a grayscale and co2 use it for depth. If you speak about grayscale and use a dither, it’s not a grayscale, it’s a dithered photo, much like a printing press.
@bulldog has some very good image work with lasers, might want to check some of his work out.
Fiber machines, take out material, this really doesn’t occur with an led, so fiber machines can make use of 3Dslice mode Lightburn created.
Good luck … hope this helps.
