Definitions
- the invention relates to a method for printing an object that is not paper by means of a digital printing system which has several ink applicators for applying printing ink of different colors to the paper, wherein in the method an ink carrier element is guided past the ink applicators in a feed direction, the Device has a temperature control device and an electrical control, wherein the temperature control device is set up to influence a temperature of the paint application units, and the electrical control is set up to control the temperature control device such that the paint application units have different temperatures.
- the invention also relates to a digital printing system that is suitable and set up for printing on paper using such a method.
- the ink carrier element to which the printing ink is applied is, for example, a printing cylinder, from which the printing ink, which is applied to the printing cylinder via the ink application units, is applied to an applicator roller that prints on the object that is actually to be printed.
- a printing tape can also be used.
- This printing belt is tensioned and set in motion over at least two rollers, for example a printing roller, which can also be called a printing cylinder, and a conveyor roller, which can also be called an applicator roller.
- the inking units print the printing ink onto the printing ribbon, which in this case forms the ink carrier element. From there it is transferred to the actual object to be printed.
- this Ink carrier element used and the object to be printed the amount and type of printing ink applied, the amount and type of any primer used, which can also be referred to as primer, but also environmental influences such as humidity and temperature.
- these parameters which generally cannot be optimized independently of each other but rather influence each other, not only have an influence on the ink carrier element to be printed and possibly the object to be printed, but also on the digital printing system used for printing.
- condensation can form on the print head. This affects the quality of print results.
- the condensate on the print head can cause individual nozzles of the print head through which ink comes out to become clogged and clogged. This can lead to the failure of an entire print head.
- increased cleaning effort is necessary to remove any condensate that forms.
- this cleaning means that a cleaning liquid that is used for cleaning is required and consumed is increased by the costs of production. Printing ink is also consumed during cleaning, which also has detrimental effects.
- the invention is therefore based on the object of proposing a method with which safe and continuous production is better enabled.
- the invention solves the problem set by a method for printing an object that is not paper, using a digital printing system which has several ink applicators for applying printing ink of different colors to the paper, with an ink carrier element being guided past the ink applicators in a feed direction
- the Device has a temperature control device and an electrical control, wherein the temperature control device is set up to influence a temperature of the ink application units, and the electrical control is set up to control the temperature control device such that the ink application units have different temperatures
- the digital printing system having a device which is set up and suitable to prevent or reduce condensation formation on the paint application units, and with this device the condensation formation on the paint application units is prevented or reduced and the method is characterized in that the temperatures of the paint application units increase in the feed direction and the temperatures of two neighboring paint applicators differ by at least 0.5 ° C and by a maximum of 1.5 ° C, whereby the temperatures of the first paint applicator in the feed direction and the last paint applicator in the feed direction differ by a maximum of 10
- the ink carrier element to be printed is therefore guided past the various ink application units within the digital printing system.
- the printing ink to be applied by the respective ink application unit is applied to the ink carrier element.
- the ink carrier element is consequently printed with the desired decor.
- this decor is then transferred to the object to be printed by rolling the ink carrier element onto this object.
- the ink carrier element is the object.
- the invention makes it possible to reduce the formation of condensate or to prevent it completely and thus solve the problem.
- a device is present for this purpose, which is preferably part of the digital printing system and is set up and suitable to prevent or reduce the formation of condensation.
- the method according to the invention it also takes on this task. This means in particular that in a digital printing system with this facility less Condensation occurs in a digital printing system that does not have this facility. This is particularly true when otherwise identical parameters are used.
- the device has a temperature control device and an electrical control.
- the temperature control device is set up to influence a temperature of the paint application units. This can happen in different directions.
- the temperature control device preferably comprises a heater which is set up to increase the temperature of the paint application units.
- the heater is particularly preferably set up to increase the temperature of the paint application units independently of one another.
- the temperature control device preferably has a cooling system which is set up to reduce the temperature of the paint application units.
- the cooling is particularly preferably set up to reduce the temperature of the paint application units independently of one another.
- the electrical control is set up to control the temperature control device.
- the digital printing system has at least one temperature sensor.
- the digital printing system particularly preferably has at least one temperature sensor per ink application unit.
- the temperature sensor is set up to transmit measurement data to the electrical control, which contains information about the temperature of the respective paint application unit. It is therefore possible to measure the temperature.
- the electrical control is preferably set up to access an electronic data memory in which a target temperature value for the respective paint application unit is stored.
- the electrical control is or preferably contains an electronic data processing device. The electrical control compares the temperature of a paint application unit measured by the sensor with the target temperature stored in the electronic data memory and is set up to control the temperature control device based on the result of this comparison.
- the electrical control sends control signals to the temperature control device, which then changes the temperature of the paint application unit. If the measured temperature is greater than the stored target temperature, the cooling of the temperature control device is controlled by the control signals and reduces the temperature. If the measured temperature is smaller than the stored target temperature, the heating of the temperature control device is controlled by the control signals.
- the electrical control is set up to control the temperature control device in such a way that the paint application units have different temperatures.
- the temperatures of the paint application units particularly preferably increase in the feed direction.
- This embodiment is based on the knowledge that the amount of liquid printing ink applied to the ink carrier element increases in the feed direction. This also increases the risk of condensation forming from the amount of liquid applied. The higher the temperature of the paint applicator, the lower the probability that liquid in the area surrounding the paint applicator will condense on the paint applicator. It is therefore generally advantageous if the temperatures of the paint application units increase in the feed direction.
- the temperatures of two adjacent paint application units differ by at least 0.5 ° C, preferably by at least 0.7 ° C, particularly preferably by at least 1.0 ° C.
- the temperatures of two adjacent paint application units differ by a maximum of 1.5 °C, preferably by a maximum of 1.3 °C, particularly preferably by a maximum of 1.0 °C.
- the digital printing system has, for example, four ink application units whose temperatures increase in the feed direction.
- the temperature of the first inking unit is 29 °C
- that of the second inking unit is 30 °C
- that of the third printing unit is 31 °C
- that of the fourth printing unit is 32 °C.
- the temperature between the ink carrier element to be printed and the print head is as low as possible in order to reduce the risk of condensation forming. Since the ink carrier element is also heated as it passes through the digital printing system, it is advantageous if the temperature of the ink applicator also increases in the feed direction.
- the amount of printing ink that is applied by the respective ink applicator increases with the temperature of the ink applicator. It is therefore advantageous to limit the overall difference in temperature between the first and last paint application units.
- the temperatures of the first paint application unit in the feed direction and the last paint application unit in the feed direction differ by a maximum of 10 ° C, preferably by a maximum of 7 ° C, particularly preferably by a maximum of 5 ° C.
- the digital printing system preferably has a cooling device which is set up to cool the ink carrier element.
- a cooling device which is set up to cool the ink carrier element. This is particularly advantageous when an indirect printing process is used.
- the printing ink is transferred from the ink application units to the ink carrier element and from there directly or indirectly to the object.
- the ink carrier element therefore rotates within the digital printing system and is guided past the ink application units several times.
- it is a single-pass system, as all the colors used for printing are applied to the ink carrier element in a single pass.
- the ink carrier element heats up a little with each cycle, so that the temperature of the ink carrier element can rise during ongoing operation of the digital printing system.
- the cooling device is present to reduce the associated increased risk of condensation formation.
- the device preferably has an additional temperature sensor which is set up to determine the temperature of the ink carrier element.
- the measured values determined by these additional sensors are transmitted to the electrical control, preferably the electronic data processing device, in which they are preferably compared with stored target values. Depending on the result of this comparison, the electrical control controls the cooling device.
- the device has at least one air flow deflector which is arranged between two paint application units and is set up and suitable for deflecting an air flow from one paint application unit to an adjacent paint application unit. An air flow that would flow from one paint applicator to the adjacent paint applicator without the air flow deflector is consequently deflected by the air flow deflector.
- An air flow deflector can, for example, be designed in the form of a wall or plate that is placed or positioned in the path of the actual air flow. This is particularly advantageous in order to prevent a spray mist of printing ink, which arises when the printing ink exits the ink application unit, from being caused by air flows, for example from the moving parts of the digital printing system, from the ink carrier element moving through the digital printing system and/or can be caused by air currents in the hall in which the process is carried out, can be directed or blown from one paint application unit to the neighboring paint application unit. This also reduces the amount of liquid at the location of the neighboring paint application unit, which also reduces the risk of condensation forming.
- the device particularly preferably has at least one air flow deflector between two adjacent paint application units. This means that whenever two paint application units are arranged adjacent to one another, there is at least one air flow deflector between these two paint application units.
- the device preferably has at least one air extraction device which is arranged between two adjacent paint application units and is suitable and set up to extract air between the two paint application units.
- the device particularly preferably has at least one air suction device between two adjacent paint application units. This means that whenever two paint application units are arranged adjacent to one another, there is at least one air suction device between these two paint application units.
- the air suction device creates a spray mist of ink that is created when the printing ink emerges from the ink application unit. sucked off.
- the air suction device is preferably part of a cooling system for the temperature control device.
- the device advantageously has a housing that surrounds the paint application units. In this way, moisture, spray mist and other factors that accelerate or support the formation of condensation can be kept away from the print heads of the ink application units.
- the digital printing system has a monitoring unit which is set up to detect the formation of condensation on at least one ink application unit.
- the invention also solves the problem set by a digital printing system of the type described here, which is set up and suitable for printing the object that is not paper in a method described here.
- a digital printing system comprises at least one four-color set, preferably a five-color set, for printing.
- the ink sequence is optimized for decorative printing (for example, for a color set containing five colors: blue - reddish yellow - red - greenish yellow - black).
- the waveform created, i.e. the drop shape generated on the ink applicator, allows an adjustable temperature tolerance of the print heads of at least 3 ° C, preferably 6 ° C, particularly preferably 10 ° C, without any obvious color deviation being visible in the decor.
- the digital printing system is calibrated and profiled according to its chemical-physical properties and the object to be printed. It is necessary to determine the maximum amount of ink applied and to limit ink consumption to the required level.
- the print data is created using the print profile determined and the resulting version X is ripped in the printing press. The amount of ink applied is determined from the ripped data using printing software.
- a board to be printed for example a ROH HDF board, 2070 x 2800mm
- a melamine resin-based primer is applied and dried at 210°C, preferably at 200°C.
- several layers of white for example a solution of water and titanium dioxide
- Drying takes place online after each paint application, the dryer temperature is gradually lowered to 190°C after the first application until the last paint application.
- a primer for example a reactive primer
- the plate, coated ready for printing is cooled in a cooling paternoster from 57°C to 38°C, preferably 36°C, before digital plate printing.
- the plate optimized in this way is printed online at a system speed of 80 m/min, preferably 85 m/min.
- a water-based ink system is used here. From a structural point of view, it is possible to decouple the printing unit from the printing material, i.e. the plate to be printed, using an applicator roller or transfer conveyor belt.
- the indirect order represents a temperature buffer that is adapted to the production requirements with cooling and heating through air conditioning.
- An enclosure is installed near the paint application units to limit environmental influences.
- the theoretical amount of ink applied to the decoration on the digital plate printer is used to control the temperature gradation of the individual printing units.
- the inking units are increased by 1 °C from plant 1 to plant 4 or plant 5.
- Automatic condensate monitoring is achieved using laser inspection. If a laser detects condensate early, the insertion is automatically stopped. A corresponding time gap was inserted into ongoing production to clean the heads.
- the plate buffer is preferably filled in the cooling paternoster in front of it. After cleaning, the plates are fed back into the printing process. As a result, an interval can be determined for each decor from the recorded data in relation to the production quantity. Cleaning is particularly preferably carried out at the best possible time, for example when changing the decor or another necessary production interruption (for example a sanding belt change
- the air flow deflectors with suction remove the moisture-saturated air from the print head area of the machine during ongoing production without affecting the ink flow.
- the printed panels are coated with melamine resin and dried again and cooled to 30°C in the cooling tower.
- FIGS 1 to 3 schematic representations of different embodiments of digital printing systems according to embodiments of the present invention.
- Figure 1 shows a digital printing system with a printing unit 2, which is surrounded by a housing 4. It has four color application units 6, each of which can be used to apply printing ink of one color. A fifth paint application unit 6 is shown with dashed lines. This illustrates that additional paint application units 6 are optionally possible.
- the ink application units 6 apply the printing ink to a printing cylinder 8, which forms the ink carrier element in this embodiment. It is rotated along the direction of arrow 10, so that the printing cylinder 8 is guided past the ink application units 6. The direction of movement, which is represented by the arrow 10, therefore forms the feed direction of the ink carrier element in the exemplary embodiment shown.
- the printing cylinder 8 is in contact with an applicator roller 12 which is rotated along the direction of arrow 14. Due to the contact of the application width 12 with the printing cylinder 8, the printing ink applied by the inking units 6 is transferred from the printing cylinder 8 to the applicator roller 12.
- the applicator roller 12 is rolled onto an object 16 to be printed. This is moved in the transport direction 18.
- a conveyor unit 20 is available for this purpose.
- the washing unit 22 has a dryer unit 24 which dries the roller of the washing unit 22 and thus prepares it for the further absorption of printing ink remaining on the applicator roller 12.
- a device 26 is arranged between two adjacent inking units, which is designed to reduce or completely prevent the formation of condensation on the inking units 6.
- the device 26 is an air extraction system, shown only schematically, and an air flow deflector.
- the housing 4 also ensures less condensation formation on the paint application units 6 and is therefore also part of the device 26.
- Figure 2 shows another embodiment of a digital printing device. It also has paint application units 6, with a fifth paint application unit being shown in dashed lines and thus marked as optional. Between two adjacent paint application units 6 there is again a device 26 to reduce the formation of condensation.
- the ink carrier element is not a printing cylinder 8, but a printing belt 28 that rotates in the direction of arrows 30. The direction of the arrows 30 forms the exemplary embodiment shown consequently the feed direction of the ink carrier element.
- the printing belt 28 runs around the printing cylinder 8 and a conveyor roller 32, through which the printing belt 28 is also moved in the exemplary embodiment shown. The remaining designs and details correspond to those of the design from Figure 1.
- Figure 3 shows a further embodiment of a digital printing device according to an exemplary embodiment of the present invention.
- the printing belt 28 not only runs around the printing cylinder 8 and the conveyor roller 32, but also around a cleaning aid 34 at the top. This is part of the washing unit 22, which has two cleaning squeegees 36 in the exemplary embodiment shown.
- This embodiment also has the devices 26 like the embodiments of Figures 1 and 2.
