Claims12
A method for decreasing the time spent searching for color register marks printed on a paper substrate on a printing press, said method comprising:
- acquiring an image of the paper substrate;
- and
- processing the image to determine whether the color register marks are found therein, said processing including using an FPGA.
A method for finding color register marks printed on a paper substrate of a printing press as part of a color register control system, said method comprising:
- utilizing register marks having a size of equal to or less than 0.010 inch;
- acquiring an image of the paper substrate;
- and
- analyzing the image for the color register marks using an FPGA wherein the printed color register marks are found on the substrate within 5 plate revolutions.
