With LaserWeb on a Smoothieboard (& possibly other controllers) you can perform variable power raster engraves (or simply speaking, greyscale engraves).

So, to begin with you need to calibrate your White & Black balance (in LaserWeb settings) in order to get a good contrast between the varying levels of colour.

I've created myself a calibration image to assist with this process (showing 0-100% colour in 5% increments).

You can grab the image from my OneDrive here: https://1drv.ms/i/s!AqT6a-6Vl15NiOArFCGSMZJLoBNtSA

edit: Forgot to mention the image is 360dpi (will be needed when importing into LaserWeb for testing purposes).

Okay, now that we have image capabilities in the forum, I can attach the files directly here.

Or not... Seems the forum shrinks the quality of the images.

So, grab them directly from my OneDrive for the 100% quality images.
