SCANNING METHOD AND ARRANGEMENT |
摘要 |
A novel apparatus and method for point-to-point and line-by-line opto-electronic scanning of masters mounted on a transparent master carrier and wherein simultaneous opaque and transparency scanning is accomplished to generate opaque and transparency scanning signals for each point of the master with one of the scanning signals being the actual image signal and the other scanning signal being a recognition signal for those points of the master where amplitude errors in the image signal occur due to scattered light and/or shadowing. The disruptive amplitude errors are eliminated by combining the recognition signal with the actual image signal to obtain a substantially error-free signal. |
