Definitions
- the invention relates to a method for processing lenticular sheet in sheet-fed printing machines, wherein the lenticular sheet has juxtaposed lens strips which extend transversely to the sheet running direction and the sheets of lenticular sheet are aligned in the sheet running direction and transverse to the sheet running direction.
- Lenticular sheet also referred to as a lenticular sheet
- a lenticular sheet is a clear transparent sheet having a plurality of side-by-side cambers on the front side. The bulges are parallel to each other and act as optical lenses.
- These films are used in the manufacture of lenticular products, such as. B. in the realization of image sequences or three-dimensional image impressions.
- the back of the lenticular sheet is printed with a subject and then applied opaque white or cardboard laminated.
- Each stripe sequence of all images to be merged is exactly as wide as a line stripe and must be printed just below. Only in this way, depending on the chosen viewing angle, the desired image effect, ie the visibility of image sequences or the three-dimensional image impression. If the strip sequences are not printed exactly under the lens strips, the product is unusable.
- the object of the invention is to develop a method by which it is ensured that the strip sequences are assigned exactly to the lens strips of the lenticular sheet extending parallel to the leading edge.
- Fig. 1 the section of an existing lenticular sheet 1 is shown with a view of the back 2. From the sheet 1, a front edge 3 and a side edge 4 are shown. The sheet 1 has transverse to the sheet running direction 5 extending lens strips 6. Two juxtaposed lens strips 6 form a contact line 7. In the sectional view of FIG. 2 it is shown that each lens strip 6 is associated with a respective first image strip 8, a second image strip 9 and a third image strip 10. The image strips 8, 9, 10 represent a strip sequence 11 which exactly matches the individual lens strips 6 must be assigned. In Fig. 2 it is shown that the front edge 3 is not identical to a contact line 7. In Fig.
- a sheet system with a feed table 12, a sheet accelerator 14, which is designed as a vibration system 15, and a drum 17 is shown.
- Anlegmarken 13 are shown, which can be brought from its working position in a location below the feed table 12 locking position.
- the oscillating system 15 is equipped with a sheet holding system 16 and the drum 17 is provided with a gripper system 18.
- the drum 17 close to printing units 19, wherein the drum 17 is arranged directly downstream of a first printing unit 19.1, which can be followed by further printing units 19.
- Fig. 3 is still an n-th printing unit 19.n shown.
- the first printing unit 19.1 consists of a first printing cylinder 20.1, which is associated with a first offset cylinder 21.1, which is in operative connection with a first plate cylinder 22.1.
- the nth printing unit 19.n has an nth printing cylinder 20.n with an nth offset cylinder 21.n and an nth plate cylinder 22.n.
- the printing units 19 are connected by transfer drums 23.
- the first plate cylinder 22.1 is associated with a first circumferential register control device 24.1 and the nth plate cylinder 22.n with an nth peripheral register control device 24.n.
- the circumferential register control means 24.1 to 24.n may be formed as per se known devices which are independently operable.
- the circumferential register control devices 24.1 to 24 n can also be designed so that at least the plate cylinders 22.1 to 22.n each have a single drive is assigned. The individual drive can then be influenced in such a way that they circulate before or after, whereby the circumferential register is changed.
- On the feed table 12 a held by the gripper system 18 and a with the front edge 3 to the Anlegmarken 13 fitting sheet 1 are shown.
- the feed table 12 has transversely to the sheet running direction 5 arranged channels 25 in which side pull marks 26 are mounted, which have a side stop 27 (Fig. 4). In the sheet running direction 5 extends in the feed table 12, a measuring unit 28.
- the measuring unit 28 is provided in the feed table 12, that the leading edge region of the voltage applied to the Anlegmarken 13 sheet 1 can be detected.
- the measuring unit 28 is formed in the embodiment as an optoelectronic measuring unit.
- the measuring unit 28 is arranged in a direction extending in sheet running direction 5 in the feed table 12 recess.
- the recess is closed with a transparent cover strip 29, so that the surface of the feed table 12 and the cover strip 29 form a common plane.
- the measuring unit 28 is connected to an evaluation and control device 30, can be entered in the target values and stored there.
- the evaluation and control device 30 communicates with the circulation register control devices 24.1 to 24.n and with a machine control 31 in connection.
- the lenticular sheet consisting of sheets 1 are transported by a belt table, not shown on the feed table 12 and with the front edge 3 against the position in the working position at the feed table 12 positioning marks 13 and thus aligned with the leading edge 3.
- the retired sheet 1 is detected by the side puller 26, guided against the side stop 27 and aligned with the side edge 4.
- From the aligned sheet 1 is detected by the measuring unit 28, the leading edge position.
- the position of the leading edge 3 and the position of the adjacent lines of contact 7 are generated by the measuring unit 28 and signals are fed to the evaluation and control device 30.
- the signal generated by the front edge 3 in the measuring unit 28 is blanked out.
- a control value is realized, which corresponds to a correction value to which by the circumferential register control device 24.1 to 24.n the plate cylinder 21.1 to 21 . n must be adjusted in order to achieve an exact assignment, starting from the specified as a target value touch line 7, the individual stripe sequences 11 to the lens strips 6. Since the setting / correction value of the sheet 1 located on the feed table 12 has been determined, must be taken into account during transport through each of the printing units 19.1 to 19.n, the individual circumferential register control means 24.1 to 24.n are synchronized with the passage of a measured Sheet 1 with the respective associated setting / correction value driven.
- the evaluation and control device 30 taking into account the machine speed or printing speed converted by the machine control 31.
