Color display of data

Claim 1

In forming color graphic displays directly from a sequence of input digital data values, wherein differing colors at data display points in the color displays are quantitatively indicative of differing values or ranges of values of the digital data, and processed input digital data to be displayed at the data display points having numerical codes assigned thereto from an assignment table, with the assignment table comprised of a set of numerical codes referenced as a two-dimensional matrix, one dimension of the matrix representing sample values of the data to be displayed, each sample value representing an assigned range from a plurality of ranges into which the input data values are partitioned, and the other dimension of the matrix representing a plurality of component displays, one component display for each component color in the color displays to be formed, and further with the numerical codes of the set specifying the visual image densities to be formed at data display points of the component displays and further specifying the relative density of each component color in the colors associated with such data display points according to the sample values thereof, and further with the numerical codes assigned to the data display points organized into output sequences for each of the component displays, the improved method of forming component color displays comprising the steps of: a. plotting the output sequences of numerical codes assigned to data display points by light exposure to produce corresponding film transparencies having image densities at the data display points according to the numerical codes assigned to the sample values; b. developing the exposed film transparencies to produce positive images whose image densities at the data display points vary according to the numerical codes of the output sequences for each of the plotted film transparencies for such output sequences; c. sequentially depositing a polymer coating for each of the plotted output sequences over previously deposited coatings according to the image densities of the positive images formed for each of the plotted film transparencies, by performing the steps of: 1. placing a sheet of photopolymer laminate on a display backing; 2. placing one of the developed positive images having image density variations above the sheet of photopolymer laminate;
