Definitions
- the invention relates to a printing press with an integrated device for writing to at least one printing form arranged on a printing form cylinder.
- Two revolutions of the printing cylinder are required to produce a multi-color print, with only one sheet being fed to every second printing saddle. Furthermore, a printed sheet is only removed from every second printing saddle.
- Offset printers are also known as reproducers (DE-OS 3233021), in which a device for writing / imaging is assigned to the printing form which is clamped onto the printing form cylinder.
- the disadvantage here is that the means for electronically correcting the inclination of the image on the printing form are very expensive.
- the object of the invention is to provide a printing machine including an imaging device with an inexpensive inclination compensation.
- Fig. 2 tilt compensation (schematic). 1 shows a printing press with a device for writing 1 to printing forms 3 mounted on a printing form cylinder 2.
- the printing form cylinder 2 is equipped with two active surfaces 4, each of which carries a printing form 3.
- the printing form cylinder 3 are also assigned two inking / dampening units 5 which can be switched on and off alternately.
- the printing form cylinder 3 is operatively connected to a printing cylinder 6 via an offset cylinder 9 with two surfaces.
- the printing cylinder 6 has three printing surfaces 7 and, accordingly, three gripper rows 8 for gripping sheets 10 to be printed.
- the printing cylinder 6 is assigned a second formation of offset cylinder, printing plate cylinder, inking / dampening unit and device for writing, which is not identified by reference numerals.
- 11 feed elements 12 are arranged above the feeder sheet stack.
- a feed mechanism 14 is provided for feeding the sheets to be printed from the contact line 13 to the impression cylinder 6.
- the printing cylinder 6 are two transfer drums 15 for sheet removal; 16 and a delivery chain circle 17 downstream.
- a display sheet stack 21 is arranged below the delivery chain circle 17.
- the first transfer drum 15 is designed as a cocking drum and has the task of compensating for skew register errors.
- the cocking drum is rotatably mounted on one side in the machine frame; on the other hand, the cocking drum is rotatable and vertically movable, for example in an eccentric bearing.
- This bearing arrangement and its function is generally known, for example from DE 3400652 A1, so that a detailed description of the design can be dispensed with.
- FIG. 2 shows the cylinder pressure cylinder 6; Offset cylinder 9 and first transfer drum 15 designed as a cocking drum - drawn in a rotated position for better understanding.
- the feeder sheet stack 11 is arranged transversely to the longitudinal axis 18 of the printing press, ie the front edge 20 of the sheet 10 resting on the feeder sheet stack 11 is arranged at an angle of 90 ° to the longitudinal axis 18 of the printing press.
- the sheet 10 separated from the feeder sheet stack 11 is conveyed by means of the elements tion 12 promoted to the contact line 13 of the printing press.
- the contact line 13 is arranged obliquely with respect to the longitudinal axis 18 of the printing press, so that the sheet 10 to be printed and assigned to the contact line 13 is also arranged obliquely to the longitudinal axis 18.
- the degree of inclination is marked with x; with a width of the arch 10 of 740 mm, this dimension is 0.3 mm.
- the inclined position can of course also be related to the transverse axis arranged at an angle of 90 ° to the longitudinal axis of the printing press.
- the sheet 10 is transferred from the feed mechanism 14 to one of the gripper rows 8 of the printing cylinder 6, transported and provided with the printed image 19 in cooperation with the offset cylinder 9.
- the printed image 19 is applied by means of the device for writing 1 to the printing form 3 clamped on the printing form cylinder 2.
- the printing form cylinder 2 rotates and the device for writing 1 traverses, i.e. the printed image is applied undistorted line by line and thus in an inclined position relative to the longitudinal axis 18 of the printing press.
- the inclination is dependent on the resolution implemented by the device for writing 1. With a resolution of, for example, 100 lines per mm and a width of the printed image of 740 mm, this results in an inclination of 0.3 mm to the longitudinal axis of the printing press.
- the oblique print image 19 is colored by the inking / dampening unit 5 and transferred to the offset cylinder 9. This phase of the transmission is shown in dashed lines in FIG.
- the print image 19 located on the offset cylinder 9 at an angle to the longitudinal axis 18 of the printing machine is transferred to the sheet 10, which is also at an angle to the longitudinal axis 18 of the printing machine, through one of the gripper rows 8 of the printing cylinder 6. Since both inclined positions - printed image and sheet - are the same, the printed image is applied to the sheet in the normal position (dash-dotted lines in FIG. 2). The normal position is understood to mean that the boundary edges of the printed image and the boundary edges of the sheet run parallel.
- the sheet 10 is transferred in an inclined position to one of the gripper rows of the first transfer drum 15 designed as a cocking drum.
- the printed sheet is brought into normal position relative to the longitudinal axis 18 of the printing press, ie the inclined position is compensated for.
- the transfer of the sheet which is in the normal position to the second transfer drum 16, the transfer to the delivery chain circle 17 and the sheet placement on the delivery sheet stack 21 are each carried out in the normal position.
