ABSTRACT:
An apparatus for recording a binary image of a printed circuit pattern on photosensitive material. First and second rows of recording spots scan the photosensitive material. The second row is shifted by a length corresponding to approximately half the diameter of the recording spots. Each of the recording spots covers an area equal to approximaqtely four pixels. Whether a pixel is to be exposed is determined on the basis of a logical sum or product of data corresponding to four adjacent pixels.
