Title: Richard G Egan: Innovator in Printing Technology
Introduction
Richard G Egan is a notable inventor based in Dover, MA (US), recognized for his contributions to printing technology. With a total of 17 patents to his name, Egan has made significant advancements in the field, particularly in color registration and information encoding.
Latest Patents
One of Egan's latest patents focuses on printer color registration correction. This invention discloses techniques for performing color registration estimation and correction in multi-head printers. A registration target is printed by the printer and captured by an image capture device, such as a camera, within the printer. The registration target includes various shapes, each printed by a single print head, arranged in a pattern that enables cross-web and down-web registration estimates. The printer analyzes the captured target to generate these estimates and applies the necessary corrections to subsequent print jobs, thereby reducing misregistration in printed output. This technique is particularly suitable for printers with print heads that differ in resolution.
Another significant patent involves a method and apparatus for encoding and decoding information in a non-visible manner. This invention relates to the use of materials that mildly absorb radiation over a wide range of infrared wavelengths while remaining substantially non-absorbing in the visible wavelengths. The encoding process involves depositing or intertexturing a material on a base medium, where the surface dimensions and thickness contain the encoded information. The invention utilizes a lower-cost, more stable material compared to those that highly absorb infrared wavelengths. Two approaches are disclosed for decoding the information: detecting the absorption spectrum and utilizing techniques to improve the signal-to-noise ratio.
