Laser Cutting

My intention was to laser cut one to the card designs I have done. I used the laser cutter today to test the design; though it it very crisp and clear, the laser leaves burn marks on the white card. These are the two test pieces:

Both of these designs were cut from the front - the design was the right side up. I have looked at the back of the design, and it is slightly cleaner than the front.

This is the back of the design - which might just about do for the mock-ups of the cards. I am going to try laser cutting the designs as a mirror image, and possibly try using black card, so that the burns won't show.
