Definitions
- the invention relates to a method for applying a pattern to a Surface of a carrier with at least two output channels parallel rows of samples are applied.
- Such methods of applying a pattern are among others used in the production of stencils.
- a blank is sprayed on with the help of spray nozzles, which are the output channels form.
- the spray nozzles are operated by a central processing unit controlled so that the covering liquid according to the sprayed pattern to be generated.
- the spray head After applying a sample section, the spray head is around the Distance between the first and the last spray nozzle shifted by to generate the next pattern section in the manner described.
- each pattern row generated by a spray nozzle characteristic properties based on those of a series of samples are different, which was generated by another spray nozzle.
- all sample rows of a sample strip are from one and the same Spray nozzle were generated, they also have the corresponding characteristics, which is more visible through this repetition.
- connection point between the individual is particularly problematic Sample sections, because the differences in spray heads with several spray nozzles of the individual nozzles are such that they come from a spray nozzle to the neighboring are not very strong, but differ from one end of the Increase the spray head to the other. So that is typical the difference between the first and the last spray nozzle is greatest. Now that in the connection area of the sample sections of the first Spray nozzle generated pattern strips immediately on one of the last Spray nozzle strikes generated sample strips, make themselves there Differences are particularly noticeable.
- the object of the invention is another Process for applying a pattern to a surface of a support To provide, in particular, patterns without visible Get errors generated.
- the output channels and the pattern rows so displaced relative to each other in their transverse direction be that at least with a part of the output channels optional series of patterns can be applied to get a complete pattern where the individual applied with different output channels Sample rows optionally side by side with each other are mixed.
- the output channels are together by one Pattern row spacing or a multiple thereof, at most, however, by the distance between measured in the direction of displacement the first and last output channels, the output channels can be moved together by the same distance.
- the output channels can be moved together by the same distance.
- the position of an output channel and the already generated sample series are determined whether the considered output channel should create a pattern row in this position or not.
- the pattern row is already applied in the desired shape was or if a control program for applying the pattern decides that the series of samples in question will later be from another Output channel is generated.
- the feed is preferably equal to the product is the sample row spacing and the number of output channels, where each with all output channels located above the sample area be applied.
- the pattern rows can be placed on a circular cylindrical surface also be applied in the longitudinal direction of the cylinder, while the cylindrical Carrier is fixed and after applying a sample set is rotated to generate the feed.
- An advantageous embodiment of the invention is characterized in that that the pattern rows on a circular cylindrical surface essentially are applied in the circumferential direction, the in the cylinder longitudinal direction output channels offset from each other together to be moved in the longitudinal direction of the cylinder. It is advisable if the output channels during the application of the pattern rows are recorded and the shift of the output channels each after the application of one or a group of sample series, before the next or the following group of pattern series is applied becomes.
- the control program can be in this embodiment make the invention particularly simple.
- the output channels during the application of one or a group of pattern rows across continuously shifted to the sample series by the specified distance are continuously shifted to the sample series by the specified distance.
- the cylindrical surface, to which the pattern is to be applied for example as in In the case of cylindrical or roller-shaped printing forms, completely extend around the cylinder, but it is also conceivable that a itself flat but flexible carrier clamped on a cylindrical roller to create a pattern.
- the pattern is exposed by exposing one photosensitive layer is applied by means of laser light.
- the pattern by removing a spot the layer provided on the carrier is applied by means of laser light.
- the method according to the invention can be used particularly expediently if the pattern is applied by spraying on a covering liquid Spray nozzles is applied, with an opaque covering liquid is sprayed onto a photosensitive layer.
- Another embodiment of the invention is characterized in that an electrically insulating cover liquid on a continuous conductive Surface is sprayed on. It is also possible according to the invention that the carrier is a sieve, onto which a covering liquid is sprayed is that after drying and / or curing mechanically and is chemically resistant to printing inks.
- the device shown in Figure 1 for applying a pattern the surface of a cylinder 10 provided as a carrier has two receiving cones 11, 11 ', between which the cylinder 10 is clamped.
- the receiving cone 11 on the left in FIG. 1 has a main drive 12 connected, which is arranged in a corresponding housing 13, the Operating elements for the device in a manner not shown has on its front.
- the other receiving cone 11 ' is open a carriage 14 attached to the cylinder in the longitudinal direction on rails 15 is detectably displaceable to clamp cylinders 10 of different lengths to be able to.
- Cylinder 10 is a lead and drive spindle 16, hereinafter briefly referred to as a spindle, arranged for a support slide 17, on the spray head 18 as a dispensing head with a plurality of dispensing channels D1, D2, ... Dn serving spray nozzles is arranged.
- the spindle 16 is at one end with connected to a spindle drive 19, while its other end via one corresponding bearing block 20 supported on a machine frame 21 is.
- Figure 2 shows another device from applying a pattern to one Surface of a cylinder 10, which differs from that of Figure 1 essentially only differs in that they are not covered with a covering liquid but works with laser light.
- the device 2 shows a laser 22 arranged in the housing 13, which has a to the longitudinal direction of the spindle 16 parallel laser beam 23 to a laser output head 18 'transmits that on the one carried by the spindle 16 Carriage 17 is arranged.
- the laser output head 18 'points in not shown a split optics for duplicating the Laser beam 23 on the in several mutually independent beams L1, ... Ln can be switched.
- the split optics thus comprises several parallel output channels through which a laser beam L1, ... Ln to each Applying a pattern to the surface of the cylinder 10 directed thereon becomes.
- the nozzles D1 to D4 create an opaque or electrically insulating covering liquid according to the pattern sprayed on the cylinder 10.
- the cylinder 10 is driven by the main drive rotated around its longitudinal axis at a precisely defined speed.
- the Nozzle D1 applied the first series of samples M1.
- the spraying of the covering liquid takes place according to the individual sample points the sample series.
- the other nozzles D2 to D4 are switched off with the aid of the nozzle D1.
- the spray head 18 is moved by the feed V from position a to position b, in which the first two nozzles D1 and D2 lie over the surface to be provided with the pattern.
- the feed V i.e. the distance between the positions a and b, by which the spray head 18 is displaced, is equal to the product of the distance a R between the individual pattern rows Mi and the number n K of the dispensing channels, that is to say the number of spray nozzles in the present case.
- the distance between the individual spray nozzles D1 to D4 is preferably an integer multiple including 1 of the pattern row spacing a R smaller than the feed. This condition is particularly expedient if a large number of, for example, fifty, one hundred or more dispensing channels is provided on an dispensing head is.
- the feed is significantly smaller than the channel spacing.
- the distance a K of the nozzles from one another in the cylinder longitudinal direction is smaller by a pattern row spacing a R than the feed rate V.
- the two pattern rows M2 and M5 are applied in the position b of the spray head 18.
- the spray head 18 is then moved into the position c, in which the pattern rows M9, M6 and M3 are generated by the spray nozzles D1, D2 and D3, while the spray nozzle D4 is still switched off.
- the pattern rows M13, M10, M7 and M4 are then applied in position d by means of the nozzles D1, D2, D3 and D4.
- the solid lines in FIG. 3 thus represent completely applied rows of samples and illustrate the situation after application the pattern series Mi in the position e of the spray head 18 and before moving to the next position. Then in the following position the lines M12, M15, M18 and M21 are generated. So you can see that the individual Pattern series Mi between two pattern series M (i-1), M (i + 1) lie, which were generated by other spray nozzles Di.
- the pattern series Mi represent circumferential lines of the cylinder 10, which when the the area to be patterned completely around the cylinder 10 extends, are also self-contained.
- the pattern series Mi result in a multiplicity of helical lines lying next to one another.
- the output channels in the x direction are arranged side by side while the individual rows of patterns
- the output channels can be applied in the y direction move in the y direction over the flat beam while their position is maintained in the x direction.
- the output channels are then in the from Control program predetermined way preferably shifted in the x direction, in order to then move the to generate the next series of samples.
- the described mode of operation of the method according to the invention is when applying a pattern to a support always the same regardless whether with a covering liquid, with laser light for exposure or removing layers or with other suitable surface Way structuring means is worked.
- a sensible resolution and a sensible pattern row spacing is determined for a specific pattern, taking into account the quality and the desired output performance. It should be noted, however, that a certain ratio must be maintained between the number n K of the output channels and the pattern row spacing a R in order to be able to use the method according to the invention. Since the distance a K between the individual output channels across the pattern rows Mi is generally an unchangeable variable for a particular output head, only the pattern row spacing a R and the number n K of the output channels used can be varied.
- a R a K / n , where n is an integer.
- the pattern row spacing a R i.e. the resolution 1 / a R of the pattern in the direction transverse to the pattern rows, and the number of active output channels n K can be varied in order to optimally match the desired one Pattern to be adapted.
- the pattern row spacing a R can be predetermined according to the respective requirements.
- the channel spacing a K is then an integer multiple of the pattern row spacing.
