In the printing process, the compositor sets precisely shaped pieces of metal moveable type into a composing stick, which keeps the lines of exactly aligned. As the composing stick fills up with lines, the compositor deposits them into a galley, a long, unbroken column that is used to proof the text before it is divide into pages. The letters appear in reverse, which is why compositors must be careful to ‘mind their p’s and q’s’. Complete fonts of type (sets of metal letters, numbers, punctuation marks, etc.) often include ornaments, which were designed and cast (produced in a special kind of mould) to exact dimensions to ensure a precise fit. These ornaments could depict abstract or figurative pictorial elements, and they could be printed in different colours in the same way as other elements of moveable type.
