Claim	An inkjet printing method including the steps of: a) jetting on a substrate (10) one or more aqueous UV curable inkjet inks (1) including at least one photoinitiator (15) and capsules (3) composed of a crosslinked polymeric shell (4) surrounding a core (5), with the core (5) containing UV curable compounds (16); and b) applying UV radiation to the one or more aqueous UV curable inkjet inks (1) jetted on the substrate (10), characterized in that the one or more aqueous UV curable inkjet inks (1) are exposed to infrared radiation between steps a) and b). The inkjet printing method according to claim 1, wherein the infrared radiation is emitted by an infrared radiation source (8) having an emission maximum between 0.8 and 1.5 µm. The inkjet printing method according to claim 1, wherein the infrared radiation is emitted by an infrared radiation source (8) having an emission maximum between 2.0 and 3.5 µm. The inkjet printing method according to any one of claims 1 to 3, wherein the UV radiation is emitted by UV LEDs (9). The inkjet printing method according to any one of claims 1 to 4, wherein the capsules contain a colorant. The inkjet printing method according to any one of claims 1 to 5, wherein the capsules are dispersed in the aqueous medium using a dispersing group covalently bonded to the polymeric shell, wherein the dispersing group is selected from the group consisting of a carboxylic acid or salt thereof, a sulfonic acid or salt thereof, a phosphoric acid ester or salt thereof, a phosphonic acid or salt thereof, an ammonium group, a sulfonium group, a phosphonium group and a polyethylene oxide group. The inkjet printing method according to any one of claims 1 to 6, wherein the one or more aqueous UV curable inkjet inks (1) contain an optothermal converting agent for infrared radiation. The inkjet printing method according to any one of claims 1 to 7, wherein the at least one photoinitiator (15) is present in the core (5) of the capsules (3). The inkjet printing method according to any one of claims 1 to 8, wherein the at least one photoinitiator is a diffusion hindered photoinitiator selected from the group consisting of multifunctional photoinitiators, oligomeric, photoinitiators, polymeric photoinitiators and polymerizable photoinitiators. The inkjet printing method according to any one of claims 1 to 9, wherein the shell is composed of a polyurethane, a polyurea or a combination thereof. An inkjet printing device containing in order an inkjet print head (6), an infrared radiation source (8), and a UV curing device (9) for performing the inkjet printing method according to any one of claims 1 to 10, wherein the infrared radiation emitted by the infrared radiation source (8) has an emission maximum between 0.8 and 1.5 µm or has an emission maximum between 2.0 and 3.5 µm. The inkjet printing device according to claim 11, wherein the UV curing device contains one or more UV LEDs with a wavelength larger than 360 nm. The inkjet printing device according to claim 11 or 12, further containing a pre-heating device (11) upstream of the inkjet print head (6). A manufacturing line for printed textiles and leather articles containing an inkjet printing device according to claim 11 or 12 for printing on a textile or leather substrate (10), wherein leather includes natural leather and artificial leather. A manufacturing line for packaging of foodstuffs or pharmaceuticals containing an inkjet printing device according to claim 11 or 12 for printing on a packaging substrate (10).
