b) A printer that uses toner fused by a laser. Most offices use this kind of printers

c) It is a direct letterpress technique, which operates according to the round-on-round principle. It owes its name to the elastic, flexible printing form. In case of this printing technique both rubber stamps and photopolymer printing plates are used as printing form.

d) The process of printing through the unblocked areas of a metal or fibre screen, with a free flowing ink which is spread and forced through the screen by means of a squeegee. Used in the production of coloured posters, showcards, decalcomania, printed circuits, etc. Originally the screen was made almost exclusively of silk. Natural silk meshes, however, are woven from stranded threads and have irregularities and a rough surface structure. Most widely used materials today are nylon, terylene and metal.

V. Speak about the advantages and disadvantages of the gravure printing, using the following information.

Advantages: Disadvantages:

Simple printing method and press High cost of plates or cylinders

mechanism Web-fed gravure viable only for

High speed Colour correction and last-minute

Straightforward drying by corrections difficult and expensive

evaporation Proofing expensive paper

Good results obtainable on cheaper
