发明名称 METHOD FOR AUTOMATICALLY CHECKING THE PRINTING QUALITY OF A MULTICOLOR IMAGE
摘要 A sheet of paper (1) with the image to be checked passes in front of a camera (3) designed to capture three chromatic images and to emit three signals (S1, S2, S3). These signals are introduced into a device (4) applying a function F which comprises coefficients (K1, K2, K3, K10, K20, K30) previously recorded in a suitable device (2). The single signal (5) resulting from the function F is delivered to a device (6) for checking the printing quality.
