    摘要: An ejection part (3) in an inkjet printer (1) has ejection mechanisms (31a to 31d) for ejecting fine droplets of colored ink and an ejection mechanism (32) for ejecting fine droplets of clear ink, and a colored image is formed on a colored image print area of print medium (9) by the ejection mechanisms (31a to 31d). By the ejection mechanism (32), the colored image on the print medium (9) is coated with the clear ink and a code image is formed on a blank area around the colored image print area. In the inkjet printer (1), since the coating of the colored image and the forming of the code image are performed with the same clear ink ejected from the one ejection mechanism (32), improvement of wear resistance and improvement of security of the colored image can be achieved while reducing manufacturing cost of the apparatus of the inkjet printer (1).

    摘要: Color values Lab (1) are converted into corrected tone values YMCK (2) using a second table 22 in a printer profile P2. Next, these tone values YMCK (2) are converted back into color values Lab (2) using a first table 21 in the printer profile P2. Then, the color values Lab (1) before the conversion and the color values Lab (2) after the conversion are compared and differences therebetween are determined. Based on these differences, data of the second table 22 in the printer profile P2 is corrected. The above operation is carried out again using the corrected second table 22. By correcting the second table repeatedly, the accuracy of the second table 22 may be improved further.

    摘要: A CPU 20 assumes a virtual color monitor in which actual chromaticity coordinates of colors expressed by fluorescent materials are replaced by virtual chromaticity coordinates having the same hues as those of the actual chromaticity coordinates but higher saturations than those of the actual chromaticity coordinates. The CPU 20 converts colorimetric values X, Y, and Z into luminance-linear values r′, g′, and b′ for red, green, and blue, based on a relationship of color conversion for the virtual color monitor at step S23. The CPU 20 then sets any one of the values r′, g′, and b′ to L at step S24 and compares the value L with i at step S26, where i is the &ggr;-th power of j and greater than 0. In case that the value L is less than i, the CPU 20 calculates a value c based on the remaining values other than the value L among the values r′, g′, and b′ at step S27. When −ck≦L

    摘要翻译: CPU20采用虚拟彩色监视器,其中由荧光材料表示的颜色的实际色度坐标被替换为具有与实际色度坐标相同的色调的虚拟色度坐标,而是比实际色度坐标的色饱和度更高的饱和度。 基于在步骤S23中的虚拟彩色监视器的颜色转换的关系,CPU 20将色度值X,Y和Z转换为用于红色,绿色和蓝色的亮度线性值r',g'和b'。 然后,在步骤S24,CPU 20将值r',g'和b'中的任何一个设置为L,并在步骤S26将值L与i进行比较,其中i是j的γ次方,大于0。 在值L小于i的情况下,CPU 20在步骤S27中基于值r',g'和b'之间的除了值L之外的剩余值计算值c。 当-ck <= L <0时,在步骤S28,根据线性函数L进行值L的转换,其中L截距随着值c的变化而变化。 另一方面,在值L不小于i的情况下,CPU20在步骤S30中根据L的1 /γ次幂的函数执行值L的变换。 在接下来的步骤S32中,CPU20将如此获得的值V设置为与在步骤S24中设定的值r',g'和b'之一相对应的显示信号R,G和B之一。 该颜色转换处理有效地防止了在可再现的颜色范围之外的期望颜色的区域中的异常色调或色调变化。

    摘要: The present invention relates to an image reader 3 which reads the reflected light obtained by lightening from underneath a transparency board 6 on which an image original is placed, especially a cover 30 for the image reader 3 for adjusting the bend of the image original. The cover 30 comprise a vacuum pump (not shown) for reducing the air pressure in the space formed by the transparency board 6 and a bend member 48 and an airtight member 50. Therefore the image reader 3 utilizing the cover 30 can correctly read image on both a transparency original and a reflection original, and yet be easy to manipulate when reading the reflection original.

    摘要: An inkjet printer includes an image-forming part, forming an auxiliary layer on a base material by ejecting droplets of auxiliary ink and forming an image on the auxiliary layer by ejecting droplets of image-forming ink, the auxiliary ink changing a dot formation state of droplets of the image-forming ink. In a storage part, a reference table that associates each of a plurality of types of base materials with a proper dot area rate to be used when forming the auxiliary layer is stored. In a dot-area-rate determination part, a dot area rate to be used when forming the auxiliary layer on a target base material is determined as an auxiliary ink dot area rate by referencing the reference table using the type of the target base material. This enables the inkjet printer to form a highly precise image on various base materials.
