Why do i lose bits of my artwork when peeling laser dark paper?

Most of the time it simply comes down to technique.

Try to get a consistent, slow and flat peel.

Many tend to use too much force and speed up when the resistance gets less - so they rip off little bits and pieces wherever a design or letter ends.

A good and simple way to get used to a consistent peeling speed is to simply build in some "training wheels".

Whenever your design allows it, add one or two lines of toner that create a consistent resistance - teaching you the right speed during your peels.
