A rotary screen printing press includes: a sub-frame (204) supporting a screen plate (201A) with brackets (203) interposed therebetween, the screen plate (201A) being formed in a cylindrical shape; a screen-plate engagement-disengagement cylinder (228) configured to move the sub-frame (204) between a print position and a retreat position; and supporting plates (217) supporting a squeegee (213) in such a way that the squeegee (213) is engageable with and disengageable from the inner periphery of the cylindrical screen plate (201A). The supporting plates (217) are supported on the sub-frame (204).
摘要:
Die Erfindung beschreibt ein Verfahren zur Regelung der Farbdosierung in einer Druckmaschine mit einem Rechner zum Vergleich von Farbmesswerten, welche auf einem Druckkontrollstreifen erfasst werden, mit Farbsollwerten und zur Steuerung der Farbdosierung in den Farbwerken einer Druckmaschine. Das Verfahren zeichnet sich dadurch aus, dass die Rasterung der zur Erfassung der Farbmesswerte genutzten Messfelder im Druckkontrollstreifen unabhängig von der Rasterung des Druckbildes ist.

This invention discloses a numbering and imprinting machine including an impression cylinder, a stamp cylinder, a first printing cylinder, a second printing cylinder, and a moving inker which includes a first ink supply device and second ink supply device. A first space is formed between the moving inker, which is set at a retraction position, and the first and second printing cylinders so as to permit entrance of the operator into it. A second space is formed between the stamp cylinder and the first printing cylinder to permit the operator who has entered the first space to access the impression cylinder.
摘要:
The invention relates to a method for adjusting an area coverage wherein the area coverage is carried out by a volume of printing ink transferred to a print stock by an inking unit of a printing press, wherein an ink feed to the inking unit is at least disengaged in zones or interrupted in the inking unit upon reaching a final phase of a printing process previously carried out by the printing press, wherein the volume of printing ink remaining on the print stock after disengaging or interrupting the ink feed in the inking unit in the final phase of the printing process previously carried out by the printing press is transferred to the print stock until the area coverage made by the volume of printing ink transferred to the print stock equals a specified target value of area coverage for an impression of a subsequent printing process. The invention further relates to a corresponding method for execution in a printing press having a plurality of printing units.
