Abstract: A method and apparatus for controlling a lateral position of a band-shaped intermediate image carrier in an electrographic apparatus by regularly detecting a mark on the intermediate image carrier with a sensor. The band-shaped intermediate image carrier is moved in a transport direction from an image generating position at which an image is generated on the image carrier to a transfer position at which the image is transferred. A transverse position of the intermediate image carrier relative to the transport direction is detected and is time correlated with the regular detection of the mark. Intermediate position detections are carried out between the regular detections of the mark in a time-controlled manner. The detected positions are compared to stored position values or calculated theoretical position values and the results of the comparison is used to control position correction devices which change the transverse position of the intermediate image carrier.

Abstract: A method for producing compressed or expanded images is provided. For compression or expansion in a direction of the lines of the image, a line factor is determined as a starting value for a line variable. After this, the following steps are carried out cyclically: if a momentary value of the line variable is greater than zero, the source image data being processed is copied and used as a target image data Next, the momentary value of the line variable is reduced by a numerical value. If the momentary value of the line variable is not greater than zero, the next source image data is used in the place of the source image data being treated. Then the value of the line factor is added to the momentary value of the line variable. A column based expansion or compression is also provided for expanding or compressing an image in the direction of the columns. A circuit is provided for performing the expansion or compression, and a printer having the circuit is also provided.

Abstract: In a method for processing signals in an electronic engraving machine for engraving printing forms, engraving control signals for guiding the stylus of an engraving element are obtained from engraving data representing predetermined tone values between “light” (white) and “dark” (black). The stylus engraves a series of cups in the printing form. The cup depths determine the tone values actually engraved. Before engraving, the engraving control signals corresponding to “light” and “dark” are calibrated by adjustment variables so that the engraved “light” and “dark” tone values correspond to the predetermined “light” and “dark” tone values. So that the “light” engraved tone value remains constant when the “dark” tone value changes, the difference between the old “dark” adjustment variable and a new “dark” adjustment variable is formed before engraving.
