Method for printing on a décor paper and/or on a décor foil
A method is provided for printing onto a décor paper and/or foil that may be suitable for being used in decorative panels. The method may involve providing a printable substrate. A pattern may be printed on the printable substrate by ejecting droplets of ink by means of at least one inkjet printing head that may include one or more nozzles. After a first predetermined time period, the printing operation may be interrupted for a second predetermined time period and/or a controlling frequency of the printhead may be changed for a second predetermined time period.
1. A method for printing onto a décor paper and/or a décor foil, the décor paper or the décor foil being suitable for being used in decorative panels, the method comprising:
providing a printable substrate;
printing a pattern on the printable substrate;
wherein the pattern is printed by ejecting droplets of ink using at least one inkjet print head;
wherein the inkjet print head includes one or more nozzles;
wherein after a first predetermined time period the ejecting of the ink form the nozzles is interrupted for a second predetermined time period and/or a controlling frequency of the inkjet print head is changed for a second predetermined time period;
providing an ink receiver layer onto the printable substrate before the printing is performed; and
wherein the ink receiver layer is not provided during the second predetermined time period.
2. The method according to claim 1 , wherein the second predetermined period of time is shorter than the first predetermined time period.
3. The method according to claim 1 , wherein the method is of a roll-to-roll type.
4. The method according to claim 1 , wherein a relative movement between the printable substrate and the inkjet print head is performed during the printing.
5. The method according to claim 4 , wherein the relative movement is performed during the first predetermined time period and during the second predetermined time period.
6. The method according to claim 1 , wherein the change of the control frequency involves a reduction of the control frequency.
7. The method according to claim 1 , wherein the printing is performed using a set of inks; and
wherein the set of inks is of the type CMYK or CRYK.
8. The method according to claim 7 , wherein the inks are printed onto the printable substrate according to a predetermined sequence that is configured to reduce the amount of ink to be printed on the printable substrate.
9. The method according to claim 8 , wherein said the predetermined sequence is CRYK or CMYK.
10. The method according to claim 1 , wherein the printing is performed using a set of inks; and
wherein the set of inks comprises more than four inks.
11. The method according to claim 10 , wherein the set of ink comprises a light red and/or a light black ink.
12. The method according to claim 1 , wherein during the second predetermined time period a technical area is formed on the printable substrate.
13. The method according to claim 12 , wherein the technical area has a length along a printing direction, that is less than 10 mm.
14. The method according to claim 12 , wherein in the technical area is an unprinted area.
15. The method according to claim 12 , wherein in the technical area a technical pattern is printed; and
wherein the technical pattern is configured to highlight printing defects.
16. The method according to claim 1 , wherein the second predetermined time period starts only after completion of printing of a discrete number of printed patterns.
17. A method for printing onto a décor paper and/or a décor foil, the décor paper or the décor foil being suitable for being used in decorative panels, the method comprising:
providing a printable substrate; and
printing a pattern on the printable substrate;
wherein the pattern is printed by ejecting droplets of ink using at least one inkjet print head;
wherein the inkjet print head includes one or more nozzles;
wherein during printing a print quality control operation is performed;
wherein the print quality control operation is configured to identify at least one predetermined printing defect and to send a signal to a printer control unit on the basis of the identification;
wherein the printer control unit is configured to interrupt the ejecting of the ink for a predetermined time period and/or change a control frequency of the inkjet print head for a predetermined time period;
providing an ink receiver layer onto the printable substrate before the printing is performed; and
wherein the ink receiver layer is not provided during the predetermined time period.
