An ink-jet recording apparatus has ink jetting nozzles through each of which a photocurable ink is jetted for recording an image onto a recording material by an ink jetting method. The apparatus includes a color ink recording head for jetting color ink, a clear ink recording head for jetting clear ink; and an ink amount determining section for determining an amount of the clear ink to be jetted from the clear ink recording head, by causing at least one of the color ink recording head and the clear ink recording head to record a predetermined test pattern on the recording material, and on the basis of a glossiness of the recorded test pattern. A glossiness measuring device measures the glossiness, and the ink amount determining device determines the amount of the clear ink based on the measured glossiness.
An inkjet recording apparatus provided with ink jetting nozzles through each of which a photocurable ink is jetted for recording an image onto a recording material by an ink jet recording method, the apparatus comprising:

The present invention relates to an ink-jet recording apparatus that is equipped with ink jet nozzles for jetting photo-curable ink droplets and prints on a recording material in an ink-jet recording method.
The apparatus for recording images with UV-curable ink in the ink-jet recording method has merits such as capability of recording images on various kinds of recording media and capability of printing without printing plates, if necessary.
Patent document 1 discloses an art of image recording by an ink-jet recording method using photo-curable ink without providing an ink receiving layer on the surface of a recording material and without deteriorating the image quality due to oozing of ink.
FIG. 1 shows the main portion of an ink-jet recording apparatus which is the first embodiment of this invention.
FIG. 2 shows the functional block diagram of a control device of the first embodiment.
FIG. 3(a) and FIG. 3(b) respectively show test patterns used in the first embodiment of this invention.
The preferred embodiments of this invention will be described below with reference to the accompanying drawings. However, it is to be understood that the invention is not limited to these specific embodiments.
Referring to FIG. 1 is explained the main configuration of the ink-jet recording apparatus which is a preferred embodiment of this invention. FIG. 1 shows the main portion of the ink-jet recording apparatus.
The ink-jet recording apparatus 1 is of the serial type which of ink-jet recording apparatus which jets UV-curable inks onto a recording material to form an image while driving the recording heads to scan the recording material. The ink-jet recording apparatus 1 is equipped with a platen 6 to support a recording material P from under it and a conveyance device 7 (see FIG. 2) to convey the recording material P from the platen 6. Further above the platen 6, the ink-jet recording apparatus 1 is equipped with a carriage 8 (see FIG. 5) as a head carrying means to move the recording heads 12 and light irradiation devices 4 and 5 perpendicularly to the movement of the recording material P.
