Lightburn printing darker then Luban

Hi, i have been playing around with Lightburn for a while now and i have noticed something that is annoying.
When i print images in Lightburn they are always a lot darker then if i did them in Luban.

Starwars skateboard deck

  • Darth Vader was done using Luban, and is overlay-ed on the Death Star 2
  • The clone trooper was done in Lightburn, its come out a lot more ‘charred’ and darker

I have done this with tile prints also, when i export a tile print with the same settings in both programs (as best i can match) the Lightburn print is always a little darker, i am in the process of printing a tile right now i will generate an example of the tiles code and attach them if you need to compare them.
