Title: Alan Blannin: Innovator in Trapping Techniques
Introduction
Alan Blannin is a notable inventor based in Amherst, NH (US). He has made significant contributions to the field of printing technology, particularly in the area of trapping techniques. With a total of 4 patents to his name, Blannin's work has had a lasting impact on how printed materials are produced.
Latest Patents
One of his latest patents involves a method for applying traps to a printed page specified in a page description. This trapping technique accepts a Postscript or other page description language (PDL) file and outputs a file in PDL format that includes the correct traps. The input page is divided into sub-portions, or tiles, which are individually processed by evaluating the input file in a corresponding dipping window. Each tile is analyzed to determine the presence of boundaries or intersections between page objects or color regions. A trapping analyzer generates trap vectors based on a set of desired trapping rules, taking into account existing traps and the proximity of other page objects. The trap vectors are then converted to PDL form, allowing for seamless integration into the original file.
Another patent by Blannin also focuses on applying traps to a printed page specified in a page description. This technique similarly accepts a PDL file and outputs a correctly trapped file. The input page is divided into tiles, which are processed to analyze edge data. This edge data is then converted into a list of color transitions, which is fed to a trapping analyzer that generates trap vectors according to desired trapping rules. The final trapped page can be printed on standard typesetters without the need for special trap generator hardware.
