PRINTING MACHINE HAVING A PRINTING ROLL AND AN ANILOX ROLL OR AN ANILOX SLEEVE AND METHOD FOR ADJUSTING A PRINTING MACHINE

Abstract

A printing machine includes a printing roll and an anilox roll or an anilox sleeve for inking a printing forme of the printing roll. The anilox roll or the anilox sleeve is assigned a machine-readable ID. A sensor or a camera detects the ID. A computer retrieves data which is stored in a digital memory in relation to the ID detected from the memory. The computer performs adjustments on the printing machine on the basis of the ID which is read or the retrieved data. A method for adjusting a printing machine is also provided.

10. The printing machine according to claim 1, which further comprises a chamber-type doctor for supplying said anilox roll or said anilox sleeve with printing ink.

11. A method for adjusting a printing machine, the method comprising: providing a printing machine according to claim 1; and making at least one adjustment as follows: at least one of presetting or adjusting or changing a position of AS/BS positioning of said anilox roll or said anilox sleeve relative to said printing roll by using a geometric shape of said anilox roll or said anilox sleeve for at least one of presetting or adjusting or changing a printing pressure and at least one of a distance or a position or a pressure between said anilox roll or said anilox sleeve and said printing roll; adjusting a dynamic printing pressure as a function of a printing speed; adjusting the dynamic printing pressure as a function of the printing speed and a dot density and a type of the printing forme disposed on said printing roll; adjusting a doctor blade by using at least one of an abrasiveness of said anilox roll or said anilox sleeve or a current or power consumption of a rotary motor of said anilox roll or said anilox sleeve, automatically through a motorized infeed of said doctor blade; readjusting said doctor blade by using the abrasiveness of said anilox roll or said anilox sleeve, automatically by using a motor or as an output to an operator; adjusting a dryer system and at least one of a dryer air temperature or a dryer air velocity, as a function of the printing speed; adjusting a curing system when using light-sensitive or radiation-sensitive printing inks as a function of the printing speed; adjusting an idle running speed by using at least one of ink, varnish or characteristic variables of said anilox roll; automatically selecting a washing program for ink cleaning or as a function of a viscosity of an inking system being used; automatically selecting a washing program for ink cleaning as a function of the viscosity of the ink being used; automatically adjusting and regulating an ink temperature control; automatically adjusting an ink feed as a function of the printing speed; automatically adjusting an ink feed as a function of the printing speed by changing a delivery output of an ink pump; or adjusting and regulating a viscosity value of the ink being used.

12. A method for adjusting a printing machine, the method comprising: providing a printing machine according to claim 1; and taking at least one measure as follows: comparing anilox rolls or anilox sleeves used in each of a plurality of printing units by using pre-press information; comparing said anilox rolls or said anilox sleeves used in each printing unit by using a memory for print jobs upon carrying out repeated jobs; outputting characteristic variables of said anilox roll or said anilox sleeves to an operator, and carrying out the output on a printing unit, smartphone, tablet or control desk; outputting an overview of said anilox rolls or said anilox sleeves used in the machine to an operator; outputting a recommendation to use an anilox roll or anilox sleeve by using a screen dot size of the printing plate; outputting a recommendation to use an anilox roll or anilox sleeve by using a smallest screen dot size of the printing plate; in an event of an erroneous use of an anilox roll or anilox sleeve, providing a warning by using the screen dot size of the printing plate to prevent moiré or ink bridge formation; in an event of an erroneous use of an anilox roll or anilox sleeve, providing a warning by using a smallest screen dot size of the printing plate to prevent moiré or ink bridge formation; predicting an ink consumption by using said anilox roll or said anilox sleeve and at least one of printing areas or dot densities on the printing plate; or outputting an indication of wear of said anilox roll or said anilox sleeve based on manufacturer, material, abrasiveness, cell shape, engraving, running time on the machine and power consumption of a rotary motor of said anilox roll or said anilox sleeve; and cleaning said anilox roll or said anilox sleeve with ultrasound.

Description

BRIEF DESCRIPTION OF THE FIGURES

[0054] The FIGURE of the drawing is a side-elevational view of a printing machine according to the invention.

DETAILED DESCRIPTION OF THE INVENTION

[0055] Referring now in detail to the single FIGURE of the drawing, there is seen a printing machine 1 according to the invention having an anilox roll 2 (alternatively: having an anilox sleeve 2) and a printing roll 3 (which can also be designated as a printing cylinder).

[0056] The printing roll is preferably a flexographic printing cylinder with a sleeve and flexographic plates mounted thereon (alternatively: preferably a gravure printing cylinder). Ink is preferably supplied by using a chamber-type doctor 6.

[0057] The anilox roll includes an ID 2a. The ID can be a one-dimensional bar code or a two-dimensional matrix code. The ID can be read optically. To this end, the printing machine 1 includes a sensor 4 or a camera 4. The ID can alternatively be an NFC chip or an RFID chip. Instead of the sensor/camera, an appropriate reader 4 is provided in this case.

[0058] The ID which is read is transmitted to a computer 5 of the printing machine 1. The ID can simply be a unique identification of the anilox roll, for example a number. However, it can also contain further information relating to the anilox roll, e.g. the engraving type and/or the engraving depth.vv

[0059] The computer 5 is preferably connected to at least one actuating device (not illustrated) of the printing machine, for example to a motor or an ink pump of the ink supply.

[0060] The computer 5 performs at least one adjustment on the printing machine 1, on the basis of which the ID is read.

[0061] The following is a summary list of reference numerals and the corresponding structure used in the above description of the invention: [0062] 1 Printing machine/device [0063] 2 Anilox roll/anilox sleeve [0064] 2a ID/identification feature [0065] 3 Printing roll [0066] 4 Sensor/camera [0067] 5 Computer [0068] 6 Chamber-type doctor
