Most offset printing presses function similarly, but the quality of the final product depends on a number of factors – perhaps most importantly, a certified team of press operators and quality control specialists.
On-Site Press Check
There are many quality control checkpoints throughout the entire process from file and production prepress to printing and binding. Perhaps the most vital is checking parent sheets as they’re coming off of the press.
Press operators will randomly cross reference printed sheets with a previously printed proof to confirm color accuracy, making sure that quality stays high throughout the entire print run and that the colors and registration aren’t drifting away from where they need to be as the run progresses.
