The gentleman operating the old Heidelberg printing press recognised the blank look on my face and explained everything in beautifully simple english. The printing part of this machine is relatively straight-forward. The complexities seemed to be around moving the paper to specific locations within the machine.
The press so delicately picked up a single sheet of paper, inked the printing surface and pressed the two together then placed the printed sheet onto a neat pile, but not before giving each a light spray of powder to prevent it sticking to the previous sheet. It was so violent yet so precise, to see this in action was completely fascinating and I could have watched and listened for ages.
