Have you ever watched a professional or collegiate football game and noticed the quarterback looking at enlarged pictures on the sideline? Perhaps he threw an interception because of an offensive breakdown and the coach wants to discuss what went wrong. The best way to go about this is to have visuals so the players can actually see where the mistakes were made. Though there are multiple coaches on the field, it is the coaching and management staff that sits upstairs in the team suite that provides the visual aide.
During the plays, high-tech cameras take pictures that show a large part of the field. They are taken in rapid fire mode, so each picture shows the development of the play. When the offense comes to the sideline, the images have been printed up and sent down to the field. The players can review each step of the play and discuss what went wrong, who made a mistake and how to prevent it from happening again.
These images need to be of the highest quality, as the players are using them as a reference to be better. Thanks to the development in printing technology and the exceptional printers that are being designed, the precise quality and the fast printing speeds are simultaneously possible. In old machines, the highest quality prints would have to be done using a slower print mode. But with the machines used on the football field, speed and quality are essential.
Though it is not going to be a primary concern for the staff of a football team, it is critical to have backup printer toner and the right kind of paper. Usually the images are enlarged so a wide format machine may be required and to get the best results, glossy or photo paper should be used. This method of rapidly printing the images from previous plays has proved to help players learn during the heat of the game.
