Abstract: In a method for changing the size of line elements on a printed page, first the nature of the size change is determined and a positive/negative identifier identifying the nature (positive/negative) of the line elements is determined for each pixel of the printed page. A copy window whose expanse determines the desired size change is defined around a substitution field. Copy window and substitution field are displaced across the printed page, and the density values of the copy window are compared to the density value of the substitution field in each window position.

Abstract: In a method for processing signals in an electronic engraving machine for engraving printing forms, in particular printing cylinders used for rotogravure, an engraving control signal is obtained by superimposing engraving data, representing tone values between “white” and “black” which are to be engraved, with a periodic screen signal for generating a gravure screen. The engraving control signal guides the lifting movement of the stylus of an engraving element. As a result of the lifting movement of the stylus, a series of cups arranged in the gravure screen is engraved on the printing form. To compensate an incorrect lifting movement of the stylus (rebound effect, lag effect), the engraving data undergo digital filtering before superposition of the gravure screen.
