 		 #132074 - Just how do you know that?

I printed a positive image, and already exposed the board. The problem lies at the end of the developing stage (where the unwanted photoresist is removed).


How did you establish that?

Are you certain that the laser-printed image occludes enough of the light, i.e. is it dense enough?

Did you have the toner-side of the laser-printed image in contact with the photosensitive material? If not, the thickness of your printed substrate (~3-5 mils) probably allowed enough light to "get around it" to reduce the line width by as much as 5 mils.
