    • A color filter manufacturing method comprises the steps of forming, on a substrate, a photosensitive layer that increases or develops hydrophilic property upon irradiation of light; exposing the photosensitive layer to light for patterning to form hydrophilic areas in which hydrophilic property is relatively high and non-hydrophilic areas in which hydrophilic property is lower than the hydrophilic areas; and applying a setting ink to the hydrophilic areas with an ink jet technique, thereby forming colored portions. A color filter includes at least a photosensitive layer formed on a substrate and having hydrophilic areas in which hydrophilic property is increased or developed upon irradiation of light, and colored portions formed on the hydrophilic areas of the photosensitive layer. A liquid crystal device is constructed by using the color filter. The color filter can be manufactured inexpensively with the reduced number of steps while satisfying requisite characteristics. Color mixing, color unevenness and uncolored dots are prevented and a highly reliable color filter is provided.
    • 滤色器制造方法包括以下步骤:在基板上形成在照射光时增加或显示亲水性的感光层; 将感光层曝光以进行图案化以形成亲水性相对较高的亲水性区域和亲水性低于亲水性区域的非亲水区域; 并通过喷墨技术将设定油墨涂敷到亲水区域,从而形成着色部分。 滤色器至少包括形成在基板上的感光层,并且具有在照射光时亲水性增加或显影的亲水区域,以及形成在感光层的亲水区域上的着色部分。 通过使用滤色器构成液晶装置。 滤色器可以在减少数量的步骤的同时满足必要的特性而廉价地制造。 防止颜色混合,颜色不均匀和未着色点,并提供高度可靠的滤色器。

    • The present invention provides an ink jet printing apparatus and a preliminary ejecting method. In both a full-line and a serial printer, the amount of ink passing through nozzles of print heads is sometimes decreased below a normal value before and during actual printing. In the printer of present invention, a preliminary ejecting operation is performed taking the opportunity in which the amount of ink passing through nozzles is decreased below a normal value. Then, the amount of ink passing through nozzles recovers to the normal value at an ink ejection after the preliminary ejecting operation. Since only a small amount of ink is ejected through the nozzles during the preliminary ejection operation, dots formed on a print sheet are not noticeable. Further, it is unnecessary to move the print heads to a home position where an ejection recovering process is executed to remove ink having an increase viscosity.
    • 本发明提供一种喷墨打印装置和预喷射方法。 在全线和串行打印机中,通过打印头喷嘴的墨水量有时在实际打印之前和期间都会降至正常值以下。 在本发明的打印机中,通过将通过喷嘴的墨量减少到正常值以下的机会进行预喷射操作。 然后,在预喷射操作之后,通过喷嘴的墨水量在墨喷射时恢复到正常值。 由于在预喷射操作期间仅通过喷嘴喷射少量墨,所以形成在打印纸上的点不明显。 此外,不需要将打印头移动到执行喷射恢复处理的原始位置以去除具有增加的粘度的油墨。
