IV. Compare different methods of letterpress origination

I. Read the sentences and say if they are true or false. If they are false, correct them.

1) Letterpress plates are made from negatives rather than positives.

2) Light helps to harden the image area, and acid makes it resistant to corrosion.

3) For flat-bed letterpress printing, the thin plate is mounted on a base of plastic to bring it up to the height of the type.

4) The process of letterpress plate making is rather cheap.

5) Duplicate plates are made by making a mould from the original plain surface

6) A 'flong' is a sheet made of glued paper.

7) Long runs meant that the type for a new job must be completely reset.

8) This method first came into use two centuries ago.

9) Stereos can be made from rubber or flexible foil and are still used for printing paperbacks.

10) The mould is made of metal and its surface is sprayed with golden compound

II. Find the equivalents of the following terms:

1) offset origination a) кислота

2) four-colour origination b) круглий стереотип, вигнута форма

3) light-sensitive emulsion c) електролітна ванна

4) negative d) компонент срібла

5) resistant e) виготовлення форми для офсетного друку

6) corrosion f) дублікат друкарської форми

7) acid g) картонна матриця

8) to mount h) повторно набрана друкарська форма

9) curved plate i) типографський сплав

10) filmset type j) стійкий

11) duplicate plate k) тверднути

12) to mold l) паперова палітурка

13) 'flong' m) бакеліт

14) metal alloy n) негатив

15) to solidify o) монтувати, встановлювати

16) to reset p) фотонабірний шрифт

17) bakelite q) відливати

18) paperback r) виготовлення чотириколірної форми

19) electrolytic bath s) корозія

20) silver compound t) світлочутлива емульсія
