How are books made?
First, the book needs to be typeset. The publisher chooses a font and converts the text into a long column of words called a galley. This is then proofread by editors before they are divided into pages. Then they make a high-quality printout called a camera copy, or mechanical. Each page is photographed and the negatives are stuck onto a sheet called a flat, or goldenrod. UV light is shone through the flats onto photo-sensitive paper to make blueprints. If the blueprints are ok, the negatives are then burnt into aluminium to make plates. These then go to the printing press and, finally, the pages are printed and bound.
