I’ve recently been trying to engrave some monochromatic designs in tile and slate. To this end, I’ve saved my images as 300 dpi 1-bit .png files to upload. To my understanding, a B&W image should require no dithering via “vary power” or “covert to dots”, as the interface should only be burning black and ignoring white, however selecting either of these options appears to give different, yet equally unsatisfying results. I’m thinking the issue must be with my image, but I’m struggling to understand why. Would appreciate any ideas if folks have looked into this before. I found one post about trying to force single color by changing the “minimum power” setting while using “vary power”, but short of converting it to a vector image, why doesn’t this work?
Image I was trying to engrave:
And the result from “convert to dots” method, 340 lpi, where the dots are huge despite seemingly being unnecessary (if you right-click open the image in a separate tab, it should let you zoom in to see the lack of definition around any of the dots):
Here’s a copy of the exact .png I used, as you can imagine the top image would engrave the inverted version of the result I showed:
Many thanks ahead of time for any helpful suggestions!
