Latest Patents

John O Renn holds a patent for a "Method and apparatus for marking photographic orders." This invention presents a system designed to match the envelope, film, and prints that constitute a photographic processing order. The method involves reading a preprinted bar code from the customer envelope and printing that bar code on a segment of continuous splice tape. This segment is then used to join the identified film to other films, forming a continuous reel. The bar code from the film can be read after processing, allowing it to be matched to the envelope bearing the same bar code. Additionally, the method encodes a portion of the identifying code on the prints made from the film, ensuring a three-way match. The splice tape printer utilized in this method features a print head capable of simultaneously printing a bar code number and a human-readable number on the tape segment.
