Abstract: The present invention provides a method of and apparatus for selecting and displaying a printing process during prepress processing of one or more selected image parts which distinctively shows a target image part for the selected process, thus improving the working efficiency. When the operator moves a pointer PT to a first image part I1 on a CRT screen with a mouse 22 to select the first image part I1 (FIG. 3A), a menu button MB and a first arrow AL1 running from the menu button MB to the position of the pointer PT are displayed on the CRT screen (FIG. 3B). When the operator further selects a second image part I2 (FIG. 3C), a second arrow running from the menu button MB to the current position of the pointer PT is displayed on the CRT screen (FIG. 3D). When the operator clicks the menu button MB with mouse 22 (FIG. 3E), a pull-down menu MN including a plurality of process titles is displayed on the CRT screen.

Abstract: A non-volatile memory connected to state logic is provided for autoloading peripheral target devices at power-on or system reset. The memory is preloaded with commands and data. At power-on or system reset the commands are executed in sequence, transferring data to selected target devices. Data is output in bit-serial fashion on a single line. Target devices are individually selected through use of separate clock lines. Clock signals on the clock lines can be internally generated using the state logic or a target-device-supplied clock can be received under program selection. The system reset signal is intercepted and retransmitted to control target device mode. System reset polarity, enable signal polarity, data block length, clock direction, internal clock frequency, and power-saving shutdown upon completion of all transfers are all programmably selectable features.
