I normally only cut with vectors but my current project has both cuts (lower speed, higher power) and vector engravings (higher speeds and lower power) so I am using color in CorelDraw to differentiate the cuts (black) and engravings (red or blue, for two different levels of engraving). When I transferred the file over to the laser's computer and ran a test job, I found some, but not all, engravings were cut through. Checking those vectors, I found they weren't pure red 255/0/0 or blue 0/0/255. For example, some of what should have been blue (0/0/255) were 6/0/255, some 12/0/255, and some 17/0/255. Similar changes happened with reds.
At first, I thought I'd somehow set the colors incorrectly but I fixed them and took the file back to my workstation for further edits. Opening the file there, I again found some of the reds and blues changed. Both machines have the same version of CorelDraw. I just saved my updates and closed the file, then decided to check something else. When I reopened the file on the same machine moments after closing it, I found some of the red and blue colors had changed again!
Any ideas on what's happening and how to stop this? There are too many vectors in too many groups to keep manually changing them!

PS - On further investigation, I found that saving, closing and reopening the file caused the reds and greens to "increment"! A vector that had been set to 0/0/255 (blue) when saved becomes 6/0/255 when reopened. If left unchanged and the file is again saved/closed/reopened, that vector will be 6/0/255. Next cycle it becomes 12/0/255, then 17/0/255, then 21/0/255! I can reset one vector back to 0/0/255 and leave another at 6/0/255, save, close and reopen, and the one I reset will be 6/0/255 while the other has incremented to 12/0/255. Black vectors stay black. Red vectors change similarly but with different increments beginning 255/0/0, 255/0/2, 255/0/6.
I just tried cyan, green and yellow, with similar changes: cyan mutated from 0/255/255 to 4/255/255, green from 0/255/0 to 4/255/2, and yellow from 255/255/0 to 255/255/2.
PPS - The shades of gray 10%-90% don't change, nor does magenta (255/0/255) or orange (255/102/0). A number of other colors picked from the color palette do. ??? For now, I'm converting to red and blue to orange and magenta, but I'd still like to find out what's going on!
