Abstract: In an inkjet printing apparatus, heaters are enclosed with a heater casing, achieving accumulation of heated air and efficient performance of heating. A blowing fan blows air to the heaters. The heater casing includes a blowing port configured to narrow and blow warm air heated with the heaters to a transportation path outside the heater casing in a direction along the transportation path. The warm air narrowed at the blowing port obtains an increased air velocity thereof. In addition, uniform air-quantity distribution and uniform heat-quantity are obtainable. Moreover, the heaters face the transportation path. Consequently, the heaters are provided closer to the transportation path than a conventional external heater. This suppresses heat loss.

Abstract: The shape of a target mark extracted from within a print sample and to be reproduced on a print is entered. A color chart is printed comprising multiple color patches in which the shape of the target mark is simulated.

Abstract: In a projection image displaying device which projects imaging light emitted from a projection lens by being reflected by a projection mirror, an air inlet for sucking external air is provided at the position of a sealing mechanism of the projection mirror. Air blown off through openings provided around the projection lens is sucked into a case through this air inlet. When a cooling operation of cooling components within the case is to be performed by sealing the projection mirror, a sucking operation through the air inlet is stopped. This prevents dust in the external air from adhering to a reflective surface of the projection mirror regardless of the installation state of the projection image displaying device.

Abstract: It is determined whether an entered designated color is a color within a gamut of a printing machine or not. If the designated color is judged as being not a color within the gamut, then the designated color is mapped to converted colors within the gamut according to a plurality of gamut mapping processes. One of the gamut mapping processes which corresponds to one of the converted colors is selected. If the designated color is judged as being a color within the gamut, the designated color is set as a reference color. If the designated color is judged as being not a color within the gamut, then the selected one of the converted colors is set as the reference color.

Abstract: The shape of a target mark extracted from within a print sample and to be reproduced on a print is entered. A color chart is printed comprising multiple color patches in which the shape of the target mark is simulated.

Abstract: At least one color patch, which is extracted as a candidate patch from within a color chart, is colorimetrically measured and a color value is acquired. Based on a color value of a designated color to be reproduced on a print and a color value of the candidate patch, a corresponding position on the color chart responsive to the color value of the designated color is calculated. Instruction mark images indicative of the calculated corresponding position are displayed respectively, together with a simulating image, in which a layout of multiple color patches on the color chart is simulated.

Abstract: An image forming apparatus or an image output system includes a main image forming section for imposing a plurality of jobs and thereby generating at least one piece of main image data, and an interleaf image forming section for generating an interleaf image depending on the jobs of the main image data and generating interleaf image data including the interleaf image.

Abstract: A group of spectral data of print mediums and a group of laminating film spectral data are stored, which correspond to a plurality of colors on a color chart. The type of print medium and the type of laminating film are entered. From the group of spectral data of print mediums and the group of laminating film spectral data, spectral data corresponding to the entered type of print medium are entered as first spectral data, and spectral data corresponding to the entered type of laminating film are entered as second spectral data. Colorimetric value data of the colors are calculated using the first spectral data and the second spectral data.

Abstract: Image data used for printing a designated color adjusting color chart having color patches with a printing machine are generated, color values and positions of the color patches being associated with each other. A patch selection image simulating the positions of the color patches on the color chart is displayed. Coordinates corresponding to the position of a color that has been selected as a color that is closest to the designated color from the color patches of the color chart, are indicated on the displayed patch selection image. Color values of the color that is closest to the designated color are calculated based on the color values and positions that are associated with each other and the indicated coordinates.

Abstract: A chart simulating image is displayed, which simulates the layout of color patches on a color chart. Color bars, which match the tendency of color changes depending on the layout of the color patches, also are displayed together with the chart simulating image. Mark images, which are indicative of a color presentation range according to the color patches in a color space represented by the gradation images, also are displayed together with the color bars.

Abstract: An inkjet printing apparatus 100 includes an inkjet head holder 11 holding inkjet heads 2, and a pair of head cap holders 12 and 13 holding head caps 3. When the inkjet head holder 11 is in a raised position, the head cap holders 12 and 13 are arranged as horizontally juxtaposed in a capping position, where the respective inkjet heads 2 and the respective head caps 3 are opposed to each other, below the inkjet head holder 11. When the inkjet head holder 11 is in a lowered position, the head cap holders 12 and 13 are arranged as vertically superposed in a withdrawn position laterally of a vertical movement area of the inkjet head holder 11.

Abstract: In a projection image displaying device which projects imaging light emitted from a projection lens 2 by being reflected by a projection mirror 3, an air inlet 4d for sucking external air is provided at the position of a sealing mechanism 3a of the projection mirror 3. Air blown off through openings 2a, 2b provided around the projection lens 2 is sucked into a case through this air inlet 4d. When a cooling operation of cooling components within the case is to be performed by sealing the projection mirror 3, a sucking operation through the air inlet 4d is stopped. This prevents dust in the external air from adhering to a reflective surface of the projection mirror regardless of the installation state of the projection image displaying device.
