摘要:
There is disclosed an ink jet color recording method for forming a multi-color image on a single recording medium using a monochrome recording apparatus, which includes a mounting portion for detachably mounting an ink recording head for performing recording on the recording medium by ejecting a monochrome ink, a feed unit for feeding the recording medium to a recording region of the ink recording head, and a discharge unit for discharging the recording medium passing the recording region. In first step, first recording information is supplied to a first ink recording head, attached to the mounting portion, for ejecting a first ink, recording is performed using the first ink on the recording medium fed to the recording region by the feed unit, and the recording medium is discharged by the discharge unit. In the second step, second recording information is supplied to a second ink recording head, attached to the mounting portion in place of the first ink recording head, for ejecting a second ink of a color different from the first ink, the recording medium, on which recording using the first ink has been completed, is fed to the recording region by the feed unit, recording is performed using the second ink, and the recording medium is discharged by the discharge unit. In the third step, third recording information is supplied to a third ink recording head, attached to the mounting portion in place of the second ink recording head, for ejecting a third ink of a color different from the first and second inks, the recording medium, on which recording using the first and second inks has been completed, is fed to the recording region by the feed unit, recording is performed using the third ink, and the recording medium is discharged by the discharge unit.

A first printing pattern is formed for a patch (350) by means of a paper feed upstream side part (311) of a black head (310). Then, a second printing pattern is formed for the patch (350) by means of a cyan head (321) in the following scans, and density of the patch (350) is read by a reflection optical sensor (30) in a scan after the completion of both patterns.

摘要:
An ink is ejected at the same timing from ejection orifices in a number corresponding to an ink quantity 7% or less of an ink quantity ejected from all the ejection enabled ejection orifices of a plurality of ejection orifices of a recording head, and the ink ejection period from all the ejection enabled ejection orifices is set to be 70% or more of the driving period. Since the quantity of an ink ejected per unit time is minimized, and the negative pressure level generated in a common ink chamber can be set to be closest to normal pressure, the amplitude of a refill oscillation is minimized to stabilize ejection, and the driving frequency can be further increased.
