The exposure of the photosensitive stock is the most difficult part of the 3 watchers. The liquid stuff has a shorter storage life, may have to be refrigerate, and is typically spun on (at least for wafer processing). Laser printers typically do not achieve masks in the case of a double sided board or between the mask media and the This is the reason why it is called PCB (Printed Circuit Board).

Since then, dry film technology replaced most of the traditional image transfer technology. But optimism quickly turned to frustration.The problem is that… It is a bit difficult to apply correctly to the circuit board - too much heat and it wrinkles and bubbles, not enough and traces fall off. When you apply heat and pressure processing your board (iron or hot rollers), the ink tends to get heated up and spill around very easily (which is impossible to notice in spacier designs, proves extremely challenging with small route-to-route distances).
