Photo resist work as great as the printing on the plastic film. My printer does not print black areas perfect and I could see the imperfections on finnished circuit board.

HP laser printers seems to work great. Have anyone tried Brothers black and white laser printers?

I can understand why scrubbing the photoresist was mild then you drink wine while waiting for the sun to do the work. Usually I wash it away, remember to be careful with the eyes and put powder/water in correct order.
