Title: The Innovative Contributions of Donald L. Swihart

Introduction

Donald L. Swihart is a notable inventor based in Stillwater, MN (US), recognized for his significant contributions to the field of flexographic printing technology. With a total of six patents to his name, Swihart has developed innovative methods that enhance the efficiency and effectiveness of printing processes.

Latest Patents

One of his latest patents is an aqueous processing method for flexographic printing plates. This system is designed for processing a photosensitive flexographic printing plate that has a latent image formed by image-wise exposure of an aqueous-processable photopolymer. The system utilizes a first aqueous processing solution to clean the latent image and then employs a second aqueous processing solution, which is devoid of the photopolymer, to wash the resulting relief image. The processing solution tank is configured to combine both used aqueous processing solutions, ensuring optimal performance while maintaining predefined maximum volume and concentration levels.

Another significant patent by Swihart is also an aqueous processing method for flexographic printing plates. This method involves using a main processing unit to develop a relief image by removing unexposed photopolymer with an aqueous processing solution that includes a first dispersing agent. The photosensitive flexographic printing plate undergoes mechanical cleaning during this process. The used aqueous processing solution containing the removed photopolymer is returned to the processing solution tank, while a secondary processing unit washes the developed relief image with a secondary aqueous processing solution that includes a second dispersing agent.
