Embodiment Construction

[0068] figure 1 The figure showing the first embodiment of the present invention is also a cross-sectional view schematically showing the configuration of the case where the light irradiator equipped with the ultra-high pressure mercury lamp of the present invention is applied to the head of an inkjet printer.

[0069] In addition, in the following, the case where an inkjet printer is used for image printing will be described as an example, but it is also applicable to the case where a pattern such as a circuit is formed.

[0070] In the inkjet printer of this embodiment, except that the structure of the light irradiator is different, other features Figure 8 The structure shown is the same.

[0071] That is, the inkjet printer 1 is provided with a head 1a that is equipped with nozzles for ejecting a liquid material such as photocurable ink, for example, ultraviolet curable ink, etc., as tiny droplets toward the base material 5. (not shown) inkjet head 4, and two inkjet head...

Abstract

The present invention relates to a printer, which uses a lamp with wavelength of below 300nm without almost emitting light as a light source, even though the electric force of the lamp is increased, any substrates will not distort due to being heated. An electric discharge lamp is a short arc type extra-high-pressure mercury vapor lamp in which a pair of electrodes is provided in an electric discharge container, wherein mercury of 0. 08-0. 30 mg/mm3, rare gas, and halogen are enclosed in the electric discharge container and a distance between electrodes is 0. 5-2. 0 mm, and the lamp contains a plurality of light of wavelength of 300 to 400 nm, but almost contains the light with wavelength below 300 nm. The electric discharge lamp extends along an optical axis of a reflector with a revolution paraboloid shape reflecting face wherein the pair of the electrodes are arranged so that a straight line formed by connecting the pair of electrodes, and the lights emitted from the lamp become parallel lights, wherein part of the lights are emitted from a light-emitting outlet directly, and the other part are emitted from the light-emitting outlet after the reflection of the reflector. A linear illumination area IA is formed on the substrate.

Description

technical field [0001] The present invention relates to a printer that ejects photocurable ink onto a recording medium, irradiates the ink with light, and records an image on the recording medium. Background technique [0002] Gravure printing can be used to create images easily and cheaply. For this reason, in recent years, the recording method called inkjet has been gradually applied to printing fields such as photographs, various types of printing, marks, and special printing of color filters. [0003] In particular, in the inkjet recording method, printers that eject / control fine dots, inks that have been improved in color reproduction, durability, ejection suitability, etc., and ink absorption, color rendering properties, Combining special paper with significantly improved surface gloss, etc., can achieve high image quality. [0004] The above-mentioned printers can be classified according to the type of ink, but also include a photocurable inkjet method using a photoc...
