A method for increasing optical fidelity of conventional laser printers by intercepting a page description word processing output file to be sent to a printer, expanding the text in that file, rotating the expanded text, and causing the expanded, rotated text to be printed along the length of multiple sheets, along with registration marks, for later assembly into an enlarged version for photo-reduction.

A system and method of applying marking fluid using plotter driven marking instruments for drawing images onto a large sheet in a minimal amount of strokes with the aid of a computer. The system includes providing the computer with data defining the desired images, and providing a preselected plurality of marking instruments having different diameter tips and stroke widths. The computer is also provided with data corresponding to and representing the stroke width for each of the preselected plurality of different diameter tip marking instruments. The computer calculates the coordinates which each instrument is to fill in on the sheet. This is based upon the size, shape, and location of the image as compared to available stroke widths. The computer provides control signals to the plotter for controllably selecting and causing each different diameter tip marking instrument to fill in the sheet at locations according to the calculated stroke coordinates. The availability of a plurality of different size tips allows the computer to instruct the plotter to fill in the image with a minimal number of strokes to reduce the completion time and wear on the plotter.

A process and system for generating an aesthetically altered character design with the aid of a computer includes the steps of providing the computer with coordinates defining a wide fixed reference character shape, providing the computer with corresponding coordinates defining a narrow fixed reference character shape, providing the computer with a desired degree of alteration to be made to the character shape in relation to one of the reference character shapes, and calculating in the computer coordinates of an aesthetically alterable character shape. Each of the calculated coordinates for the aesthetically altered shape is generated by interpolating in an amount equal to the desired degree between corresponding coordinates to the wide fixed and narrow fixed reference character shapes. When the desired degree of alteration is outside corresponding coordinates of the wide fixed and narrow fixed reference character shape, the calculated coordinates are generated by extrapolating between the corresponding coordinates of the wide fixed and narrow fixed reference character shapes.

A system and method of operating an automatic plotter device having marking instruments for drawing images onto a large sheet with the aid of a computer includes providing the computer with data defining the desired images, providing the plotter with a preselected plurality of marking instruments each having a specified stroke width, providing the computer with data corresponding to and representing the stroke width for each of the preselected plurality of marking instruments, calculating in the computer for each marking instrument the coordinates upon which each instrument is to draw onto the sheet based upon the size, shape, and location of the image and the appropriate width, and generating control signals to the plotter for controllably selecting and causing each marking instrument to draw on the sheet at locations according to the calculated stroke coordinates. The sheet may be paper, vellum or other clear plastic utilized for the screen exposure preparation process for purposes of screen printing. The marking instrument is preferably a felt tip pen containing opaque ink.
