spot color lithography
ink jet simulation
The dot structure of spot color lithography, often used to produce Census questionnaires, is illustrated on the left (approximately 12 X actual size). The red square indicates the approximate size of a 200 dpi scan pixel. A close approximation to this dot structure can be achieved using a high resolution ink jet printer, as seen on the right. Note, however, that this is not the native dot structure produced by the printer. Rather, selected image processing techniques are used to craft a digital image that drives the printer to the desired result. This capability, termed simulated spot color, enables rapid generation of unique test pages, facilitating rapid turnaround of design changes and evaluation of far more questionnaire background colors. Please note: This example is not intended to illustrate a perfect match in color or percent coverage. Rather, it shows the ability to create a similar dot structure. Differences on a scale smaller than a scanner pixel will not be captured.
