Problems solved by technology

[0004] However, when the output resolution (print resolution) is lower than the input resolution (resolution of the input image) and thinning processing is performed to thin the data of the input image, the thinning processing may not be reflected. If there is a deviation from the specified color due to the previous color information, resulting in deterioration of image quality, there is room for improvement

Embodiment approach

[0051] Outline of Printing System

[0052] figure 1 It is a schematic diagram showing the outline of the printing system according to the embodiment. figure 2 It is a block diagram of the printing system according to this embodiment.

[0053] First, refer to figure 1 with figure 2 , the outline of the printing system 100 according to this embodiment will be described.

[0054] Such as figure 1 As shown, the printing system 100 according to this embodiment includes an image processing device 110 and a printing device 120. figure 2 ) receives image data to generate print data for the printing device 120 , and the printing device 120 prints an image on the medium 7 based on the print data created by the image processing device 110 .

[0055] The printing device 120 is a device that prints an image on the medium 7 by an inkjet method while unwinding the long medium 7 wound into a roll, and includes a substantially rectangular parallelepiped main body casing 1 .

Abstract

The invention provides an image processing device and a printing system. The image processing device is characterized by comprising a user interface (52), an image data inputting section (51) that inputs image data, a resolution converting section (41) that converts the image data to resolution corresponding to a printing device (120), a color converting section (44) that generates ink amount data, and a print data generating section (45) that generates print data based on the ink amount data, in which the resolution converting section includes a color inputting section (42) that inputs the spot color and the specific condition for performing a spot color replacement of replacing the spot color in the specific condition by the color converting section through the user interface, and a thinning processing section (43) that performs a simple thinning process on a spot color region (91) including the spot color in a case in which a thinning process of converting the resolution of the image data to a second resolution lower than the first resolution is performed.

Description

technical field [0001] The present invention relates to an image processing device and a printing system including the image processing device. Background technique [0002] Conventionally, there is known a color image forming apparatus (printing system) having a color specifying technology for substituting a predetermined color in a predetermined input image with a specific color (Patent Document 1). [0003] For example, in the printing system described in Patent Document 1, it is possible to replace a predetermined color (three-color gray represented by R (red), G (green), and B (blue)) in a predetermined input image with a specific color. Color designation (color adjustment) of color (gray expressed by ink plate K (black)). When the image forming process (printing) is performed after the color adjustment, the color can be expressed by the ink plate K, and therefore, an achromatic gray without tint can be formed. Moreover, the background is formed by the full coating of...
