| 摘要 |
The method provides for the use of a plate having a continuous honeycomb screen made up of lines completely surrounding hexagonal points (8 to 14) corresponding to the future ink cells of the plate to be produced. The screen used has a ruling between 70 and 100 lines to the centimetre. This method is particularly useful in photogravure printing. <IMAGE>
