This is part two showing the production of business cards on our Heidelberg Windmill. Be sure and see Part 1 showing the finished cards.
We start with a high resolution film negative. The negative is used to expose the plastic plates. The plates are attached to an aluminum base and placed into the press. The press uses air suction to pick up a sheet of paper on the left side and deliver it into the press for printing. The printed sheets are automatically stacked in the delivery pile on the right side of the press. The press prints only one color at a time. Each addition color is another pass through the press, blind impression is another separate pass as well. Letterpress is labor intensive printing, but oh so worth it.
Check out some more of the process below. See the image labels for a brief description.
