An object of the present disclosure is to perform color calibration of a printing apparatus that performs printing with a fluorescent material regardless of unevenness of a fluorescent whitening agent contained in the sheet. An embodiment of the present invention is a control apparatus including: a control unit that controls printing of a patch on a printing medium, the patch being formed by printing a fluorescent material; and a correction unit that corrects a printing amount of the fluorescent material based on a measurement result obtained by receiving light reflected by the printing medium on which the patch is printed, in which the patch is printed using the fluorescent material and a non-fluorescent material, and at least one dot of the non-fluorescent material overlaps a dot of the fluorescent material.

Example implementations relate to emulating 3D texture patterns in a printer system. One example implementation receives an image having a number of image pixels and selects from a plurality of digital substrates which each correspond to a physical substrate. Each digital substrate has luminance change data corresponding to heights of a 3D texture pattern at respective locations of the physical substrate. An image having emulated 3D texture is generated by adjusting the luminance of the image pixels corresponding to respective locations of the physical substrate and according to the corresponding luminance change data.

The disclosure relates to methods of manufacturing surface materials for construction or manufacturing use and the surface materials produced by such methods. Substrate materials, such as synthetic or engineered stone or fiber-reinforced resinous panels, can be formed in conventional ways such as casting, molding, or pressing. Layers are printed onto substrate materials to form textures, which may include inks to selectively color the printed texture, thereby enabling a wide variety of high-resolution appearances. A clear, protective topcoat is then applied to the surface materials and cured to provide a finished material.

A process of simply, cheaply, and reproducibly creating complex tissue models using screen printing and the tissue model prepared using the screen printing process. These models are amenable to high throughput screening. They will allow the study of components of disease progression and can be used for screening therapies.
