Inkjet printing device, a method of applying hotmelt ink, image-wise to a receiving material and a hotmelt ink suitable for use in such a device and method

Image Number 3 for United States Patent #6309060.

An inkjet printing device for applying hotmelt ink, image-wise, to a receiving material, wherein the inkjet printing device contains a radiation device for irradiating the receiving material provided with the hotmelt ink with radiation energy for a short time such that the hotmelt ink at least partly penetrates into the receiving material without visible feathering occurring.The radiation device can be a gas discharge lamp which irradiates for a time between 1 and 1000 .mu.s with radiation primarily in the visible wavelength range. The present invention also contemplates hotmelt inks provided with infrared-absorbent substances.
