This specific printing press plate is truly one of a kind!!! This is the first time a Canadian team has ever made the World Series and the first time in franchise history for the Toronto Blue Jays.
This particular printing press plate is ultra rare and a fantastic piece of baseball history! It is from the October 25, 1992 issue of The Sunday Star newspaper in Toronto.
It depicts the huge lines of screaming Blue Jays fans outside the gates of the Skydome. An excellent addition to any true baseball fans collection. Dimentions are 22.5" by 12.5". Please feel free to contact me for further info.
Here is some added info on what makes this item particularily rare. This aluminum printing plate is coated with a chemical called "Diazo" that changes when exposed to light. Images from the computer are used to create film negatives, which are then put over the aluminum plates and exposed to ultraviolet lights.
The plate picks up the image of the newspaper page from the negative, with the dark or exposed portions of the plate becoming a magnet for ink. The plate is then put on the printing press roller and inked with water and ink. The ink adheres to the paper areas (text & photos) and is washed away from the non-inked, gray areas by the water. This process of transferring the ink is called "offset" printing, as opposed to direct plate-to-plate letterpress printing, which was phased out in 1981. Color printing requires four plates and is standard color printing for the industry, both newspapers and magazines. Once the newspaper has been printed, the plate is instantly recycled and melted down.
