I am using Lightburn on a Scienci Longmill. A friend just asked me to do his logo for cutting boards etc. It is currently roughly business card shaped. The background color is black with the logo in light grey. I would like to change the black background to white or eliminate it all together. Is there a way to separate the logo from the background ?
Right click on the image. Click on TRACE. Adjust slider bars in the window to highlight what you want.
Click on OK to create a SVG object copy of the image. Do that and show us a picture of your preview screenshot and your cuts and layers window. Then we can finish the transformation.
I suggest masking:
What is the original format for the art you have for this Logo? Is it a bitmap/image or vector artwork?
Hi Jim, thanks for the reply. My trace option is not available. He sent it to me as a jpg and I imported it into a new file, then got stuck. I am working on some other projects and coming back to this one when I have a minute. I will keep checking for replies.
Hi Rick. This was sent to me as a jpg.
Image Trace is an available option for a selected jpeg file. Please explain what you see, helping us better understans your use of “stuck”.
If willing, share the jpeg directly or message me directly if youd rather keep private. We can take a closer look. 
Update: Thanks, I see you provided above.
OK, now you are on the path to learning laser greatness!!
Take your traced object and break it into pieces - ungroup it. Select the parts you want to have “different color” and place those on a different layer. We have 29 layers to use for output. Set the new layer to a different speed, power and line interval to achieve a different "color:
I think of the main layer (00 black) as a sheet of cookie dough. You can also punch out shapes from the main layer (i.o.w. make a hole) so the background is burned and the “hole” is left unburned. Keep at it, when you get your first successful engrave with the results you seek, you will feel very delighted.
Keep at it - the reward is copious satisfaction
The JPEG is not ideal, but you can work with it. The “noisy” colors can be a challenge, but you have tools under the ADJUST IMAGE button and the TRACE button that will help you extract a good SVG.
Here is a quick image adjust that brings out most of the detail.
You can trace this setting
and get this object
This example is from a GREYSCALE image (it will emphasis different parts of the imgae)
You can break the SVG into parts, and reassemble the pieces that work best for you. In the long run, you may decide to focust on the central design and manually add the outer text - that is another skill set
