Device for decorating containers
Description
The present invention refers to a device for decorating containers, in particular beverage cans.
Such devices typically have a plate cylinder and a rubber blanket cylinder, which carries a plurality of sequentially arranged rubber blankets in the circumferential direction thereof. The plate cylinder has a printing plate, which is provided on the entire surface or on a portion of the surface or is a raster printing plate, onto which an ink is applied by an inking unit. The rubber blanket cylinder is arranged with respect to the plate cylinder in such a way that the rubber blankets, on one hand, are in rolling engagement with the plate cylinder, and take up ink therefrom, and on the other hand, are in rolling engagement with the containers to be decorated, and may deposit the ink onto the same.
The rubber blankets are provided within a defined region, which is synchronized with the full surface of the printing plate, with raster images, which are formed by elevated raster dots of various diameters and depressed regions which lie in between. The raster dots are arranged along a regular raster. During operation, the raster dots take up ink from the plate cylinder and deposit the same in turn onto a container to be decorated. The entirety of the raster dots provides an image, which must be printed on a container.
Such devices for printing containers are generally known.
The object of the invention is to provide a device for decorating containers, which provides the best possible results of the image printing.
In order to achieve this object, a device for decorating containers with a plate cylinder, which carries a full-area or partial-area printing plate or a raster printing plate and a rubber blanket cylinder is proposed, which carries a plurality of rubber blankets so as to follow one another in the circumferential direction thereof. The rubber blanket cylinder is arranged with respect to the plate cylinder in such a way that the rubber blankets are in rolling engagement with the plate cylinder. The rubber blankets are provided with raster images, which are formed by elevated raster dots of various diameter and depressed regions which lie in between. The raster dots are arranged along a regular raster. During operation, the raster dots take up ink from the
WO2016/206955A1 plate cylinder and deposit it in turn onto a container to be decorated.
According to the invention, the rasters, in which the raster dots of the raster images are arranged on rubber blankets which follow one another, are offset relative to one another by a raster angle which is greater than 0°. Herein, the raster angle is intended as the orientation of the rows or columns of a raster with respect to the circumferential direction of the rubber blanket cylinder.
The invention is based on the realization that engraved rubber blankets (blankets) take up ink from a full-area region in the printing plate only where there is no engraving of the respective rubber blanket, i.e. only where raster dots are present, io Thus, ink is retained on the printing plate where depressed (engraved) regions are present on the rubber blanket between the raster dots, so that the full-area region in the printing plate, in the end, carries at the corresponding positions more ink, which is deposited onto the following rubber blanket (blanket). This may give rise to a kind of
Moire-effect.
The effect is reduced when a first rubber blanket does not always take up ink from the same position of the printing plate.
The rubber blanket cylinder is preferably larger than the circumference of the plate cylinder by a factor corresponding to the number of rubber blankets. The number of rubber blankets preferably is between 8 and 24, for example 12 to 16 rubber blankets.
The raster dots preferably form an amplitude-modulated (AM) raster image.
The rubber blankets are preferably laser-engraved, i.e. the depressions between the raster dots of a raster image are generated by removal of material by means of a laser. The raster angle between the rasters of the raster image of rubber blankets following one another is preferably between 5° and 85°. In particular, between 10° and 60°, for example between 20° and 40°, for example equal to 30°. It has been found that such a raster angle (angle offset between the rasters of rubber blankets following one another) effectively prevents disturbing effects like the one already mentioned.
It is also preferred if the raster images of rubber blankets following one another represent different pictures, such as different patterns, for example.
The device preferably has an inking unit, which is adapted for uniformly
WO2016/206955A1 depositing ink onto the printing plate of the plate cylinder.
The invention will now be explained by means of an exemplary embodiment with reference to figures. In particular:
Fig. 1 shows a schematic representation of a device for decorating containers;
Fig. 2 shows a schematic representation of a printing raster on a first rubber blanket; and
Fig. 3 shows a schematic representation of a printing raster of a second rubber blanket (following the first rubber blanket).
Fig. 1 shows the main components of a device 10 for decorating containers, io such as beverage cans, for example.
The device 10 allows printing of containers 12. To this end, a rubber blanket cylinder 16 with rubber blankets 18, a plate cylinder 20 with a single full-area or partial-area printing plate 22, or a 90% raster printing plate, for example, and an inking unit 14 are provided.
The plate cylinder 20, the rubber blanket cylinder 16 and the container 12 are oriented with respect to each other, during operation, in such a way that, on one hand, the plate cylinder 20 and the rubber blanket 18 are in rolling engagement with each other on the rubber blanket cylinder 16, and, on the other hand, the rubber blankets 18 are also in rolling engagement with the container 12.
Whenever a container 12 is accordingly decorated by means of the rubber blankets 18, the same container 12 is transported away and a following container 12 is arranged in such a way that it in turn is in rolling engagement with the rubber blankets 18 of the rubber blanket cylinder 16.
The inking unit 14 is adapted for uniformly supplying ink to the single, full-area or partial-area printing plate 22, or the raster printing plate of the plate cylinder 20,
i.e. it uniformly deposits ink onto the printing plate 22. When the plate cylinder 20 with the printing plate 22 rolls on a respective rubber blanket 18 of the rubber blanket cylinder 16, the printing plate 22 transfers the ink onto the respective rubber blanket 18. The rubber blanket 18 typically has raster images/printing rasters 24 in an area, which is synchronized with the full area in the printing plate, which is formed by raster dots 26 and depressions lying in between. In the region of the depressions of the rubber blanket 18, i.e. between the raster dots 26, a respective rubber blanket 18
WO2016/206955A1 takes up ink from the printing plate 22, so that at these positions on the printing plate 22 correspondingly more ink is retained.
This additional ink may be deposited onto the following rubber blanket. It is to be noted that the printing plate 22 and a respective rubber blanket 18 have an at least approximately identical extension in the circumferential direction. This means that the plate cylinder 20 is sized in such a way that it performs a complete rotation when transferring ink onto a respective rubber blanket 18.
Each rubber blanket 18 then deposits the ink previously taken up from the printing plate 22 onto the container 12, while rolling on the respective container 12.
io In the positions where the raster dots 26 of the raster images 24 provided in the rubber blankets 18 have taken up more ink from the printing plate 22, more ink is also transferred from these raster images onto the respective container 12, so that the previously mentioned problems may arise.
In order to prevent these problems, the rasters, along which the raster dots 26 of the raster images 24 are arranged, are differently oriented in successive rubber blankets, i.e. their raster rows and columns of a first raster image 24 are not parallel to the rows and columns of a second raster image 24', but form an angle therewith.
In a well-known manner, a respective raster image 25 on a respective rubber blanket 18 is produced by laser engraving, in that around individual raster dots 26 material is removed by means of a laser, in order to therefore create a depression in the rubber blanket 18. This is also known as laser engraving. The raster dots 26 are positioned according to a regular raster, and have different sizes, depending on whether the printed image at a respective position should be provided with a higher or lower ink density. Such printing rasters are also defined as amplitude-modulated (AM), since the raster dots 26 are always positioned at fixed points of a uniform raster, whereas only their size (amplitude) varies. Correspondingly, a respective printing raster of a respective raster image has also a clear orientation, which is determined by the rows or columns of the raster.
The printing raster of the raster images 24 according to the invention on successive rubber blankets 18 are differently oriented, as shown in figures 2 and 3. When the angle of the raster rows or columns with respect to the circumferential direction of the respective rubber blanket 18 or rubber blanket cylinder 16 is defined
WO2016/206955A1 as raster angle, then the printing raster of the raster image 24 of the rubber blanket 18 in figure 2 has a different raster angle than the printing raster of the raster image 24' of the rubber blanket 18' in figure 3. Since the rows or columns of the printing raster of the raster image 24 on the rubber blanket 18 according to figure 2 are exactly oriented along the circumferential direction, the raster angle for this printing raster may be indicated as 0°. The raster angle of printing raster of raster image 24' on rubber blanket 18' in figure 3 is therefore equal to about 20°.
