Printing Out PCB to 'Blue Paper"

• Each sheet of blue paper is relatively expensive. Be sure your PCB mask is correct. If your mask does not fill a whole sheet, then consolidate your work with other students if possible to make best use of the paper. If there is still room consider making an extra in case there is a problem building the first or if you think that eventually two or more boards will be built.
• Print emulsion side (dullside) down in a laser printer.
