Making an impression
On the board at the
far end of the press is a stack of the 175gsm Somerset paper used for the book.
Each sheet is slipped under grippers on the cylinder, and then rolled down the
bed of the press. The inking rollers lead the way and ink the type, followed by
the paper that is wrapped round the cylinder as it in turn rolls over the inked
type. Some sheets had to go through the press five times in cases where there
were several colours on the back and front of the sheet. An important part of
the set up is making sure that registration is maintained and that each sheet is
properly 'backed up', ie text lines on the front and back of the sheet overlap
exactly. |
