Advice on designs for wood shapes

Images should be sent as bitmap (.BMP) files. The image can be in profile (raised), so it will take ink and stamp, or in relief (cut into the material), so the surrounding area will take the ink and leave the image area clear. Whatever is in black in the file you send will NOT be cut, whatever is in white, normally the background, WILL be cut away.

If your image includes fine detail composed of tiny holes, you will need to make sure that the ink you use is thin enough not to fill the holes and loose the detail.

Fine raised lines are normally OK as the rubber is cut with a slope at either side providing support.
