There is provided an inspection device, an inkjet printing apparatus, and an inspection method capable of accurately inspecting a printed image printed on a surface of a transparent base material. A first light-emitting unit (61) emits light from one side of a transparent base material (9) toward the transparent base material (9). An imaging unit (63) images the transparent base material (9) from the other side of the transparent base material (9). As described, the first light-emitting unit (61) and the imaging unit (63) are disposed on the opposite sides of the transparent base material (9). As a result, it is possible to suppress generation of the shadow of a printed image itself in a captured image (D1). Therefore, the printed image can be accurately inspected based on the captured image (D1) obtained.

This disclosure is directed to improving the precision of color reproducibility in a whole image region of any product provided with a base layer(s) regardless of any form of the base layer(s). The RIP (Raster Image Processor) device includes a color conversion processor that applies a color conversion process adapted for presence or absence of a base layer and for a base color to content data representing part or all of details of an image layer at a respective one of positions in an image region indicated by the image layer, and an image layer data generator that generates image layer data representing ejection-related information of ink droplets of a plurality of colors using the content data that has been subjected to the color conversion process.

A printer includes a clear ink tank, a color ink tank, a clear ink injection head, a color ink injection head, a light source, and a controller. The controller includes a matte printing controller structured or programmed to cause clear ink to be injected from the clear ink injection head and to be irradiated by the light source to form a matte clear ink layer on a recording medium; and a color printing controller structured or programmed to cause color ink to be injected from the color ink injection head to form a color ink layer on the clear ink layer.

An image processing device includes a shielding degree calculation section that calculates a shielding degree of a printed layer, and a rendering section. The rendering section is configured to generate at least one of the front surface view, in which the printed object is observed from the front surface side, and the back surface view, in which the printed object is observed from the back surface side, by mapping an image data, which is color converted, to a 3D object and by performing rendering using the shielding degree of the printed layer.

An image processing device performs: breaking down a drawing command into horizontal line parameters each indicating a drawing parameter on a line-by-line basis; and reading, from a translucent image storage unit configured to store a translucent image including a translucency value indicating a transmission rate of a color value corresponding to pixel for each of a plurality of pixels, the translucency values of pixels corresponding to the horizontal line parameter, and writing color values designated by the horizontal line parameter directly into a color image storage unit configured to store a color image including a color value for each of a plurality of pixels as the color values of the respective pixels corresponding to the horizontal line parameter without reading the color values of the pixels corresponding to the horizontal line parameter from the color image storage unit, when all of the read translucency values indicate transparent.

The invention relates to a machine and method for single-pass digital printing on glass (1).

The machine comprises: a support structure (2) for securing the sheet of glass (1); and a printing bridge (3) which, during printing, can move along the longitudinal X axis of the support structure (2), said bridge supporting digital printing means (33) with print bars (100, 100, 100) comprising successive printing heads (10, 10, 10), as well as supporting a scanner (32) for capturing data relating to the positions of defects (X, Y).

The present invention provides a card which may be issued smoothly. The member card 2 comprises the base material layer 21 having the light transmittable base material and the printing layer 22, and wherein the first information 2201 to be confirmed from the first surface 21a of the base material layer 21 and the second information 2202 to be confirmed from the second surface 21b of the base material layer 21 are only printed on one surface of the base material layer 21. In the base material layer 21, the region which is printed with the second information 2202 is light transmittable region, and the second information 2202 may be visually recognized from the second surface 21b of the base material layer 21.

There are provided a chart manufacturing apparatus, a chart manufacturing method, a program, and an image forming system that do not need to switch backgrounds in a case of measuring a chart using two types of backgrounds having colors different from each other. The chart manufacturing apparatus that forms, on a transparent substrate, a chart (102) measured by applying a first background color and a second background color, forms a first measurement background image (130) on a transparent substrate (100) using a coloring material corresponding to a first background color, forms a first patch group (122) including one or more first patches (126) using a coloring material of a first color at a position corresponding to the first measurement background image, and forms a second patch group (120) including one or more second patches (124) at a position where the first measurement background image is not formed.

A white-plate graphic erosion process is performed on print data subjected to a RIP process in the following procedure. First, an erosion candidate region which is a candidate for a region in which a white-plate graphic is eroded is determined. Then, a region to be applied with an ink of a color other than white is determined. Then, an application target region is determined. Then, a region other than a region obtained by an erosion process out of the application target region is determined to be an erosion allowed region. Then, a region included in the colored region and the erosion allowed region out of the erosion candidate region is determined to be an erosion target region. Finally, the values of data of pixels included in the erosion target region among white-plate data are rewritten such that the amount of white ink applied to the pixels is reduced.
