Toggle Between Positive & Negative imgages

[Roger Lueck]

If there is a need to engrave a positive image and then engrave a negative image of the same file or object, is there a "toggle command" that can be used to change a file or object in a file between a postive image and a negative image?

Depends upon your laser system... many have a checkbox that allows you to print positive/negative images. Otherwise, you'll need to do it in a graphics program before sending it over.

I can't think of a reason you would need to engrave both. As Dan says, your graphics program should permit you to toggle.

In Corel under the effects menu you can select invert.
