Letterpress is a centuries-old printing process. Ink is applied to a raised surface and then pressed into the paper. Remember cutting a shape into a potato as a child, dipping it in paint and stamping it onto paper? Instead of using potatoes, the images you’ll see on Sweetbeets cards are made into custom engraved printing plates. When put on the letterpress, the printing plate is inked and the pressure creates an impression in the paper that you can see and feel. It’s this unique texture that distinguishes letterpress from other types of printing.
High quality letterpress printing is clearly an art! It depends on knowing just the right roller pressure to get the right amount of ink so that it settles evenly into the grooves. Each color is printed separately from its own printing plate, and it takes skill to ensure that the printed images are perfectly aligned and that the depth of impression is consistent. The paper used also makes a difference.
I witnessed how labor intensive the set up is for letterpress printing when I met with my printer the other day. It took a number of adjustments to bring the impression to the depth I had envisioned and trial and error to determine how much ink to put on the rollers. I was fascinated to see how he would listen to the running press for clues. At one point he had to custom mix the ink because it turned out to be much too dark straight out of the can. This also meant cleaning the rollers again! All this work is necessary to maintain the quality of Sweetbeets cards and reinforces why letterpress stationery is so special in this age of mass-production.
