Latest Patents
Leonard Preston holds a patent for an invention related to image reproduction. This patent focuses on the concept of the 'white point', which determines areas to be printed with zero ink. In his invention, signals representing the three color components derived from the original image are applied to a NAND gate. When all signals simultaneously indicate a zero printing color condition, the NAND gate generates a zero-ink signal. This signal modifies the zero-ink or white display on the monitor tube by inhibiting the passage of red and blue signals while allowing green signals to pass. The green signal may be periodically interrupted, resulting in pulsating green areas on the display. The operator can then adjust the white point until these pulsating green areas correspond to the original areas intended for zero-ink reproduction.
