An information processing system includes an information processing apparatus and an image forming apparatus. The information processing apparatus includes first circuitry to receive a designating operation for executing lamination processing, and transmit image data and designation data indicating that the designation operation for executing lamination processing has been received. The image forming apparatus includes second circuitry to receive the image data and the designation data, form an image on a recording medium based on the image data, and execute, in response to receiving the designation data, the lamination processing on the recording medium on which the image is formed with film.

Information processing system, image forming apparatus, and non-transitory recording medium

An image processing apparatus includes a memory and processing circuitry. The memory sequentially stores a plurality of read images read by a reading device. The processing circuitry transfers pairs of read images from the memory to an external apparatus in ascending order of priority in bookbinding to leave pairs of read images in the memory in descending order of priority in bookbinding. The processing circuitry further instructs an image forming device to execute image formation with pairs of read images in descending order of priority in bookbinding.

An electrophoretic liquid includes a first electrophoretic particle, a second electrophoretic particle having a polarity opposite to that of the first electrophoretic particle, a non-electrophoretic particle, and a transparent dispersion medium. In the electrophoretic liquid, the first, second, and non-electrophoretic particles are dispersed in the transparent dispersion medium.

Electrophoretic liquid, image display medium, and image display device

A disclosed electrophoretic fluid includes a solvent; and first, second, and third dispersible particles having different optical properties and dispersed in the solvent, the first dispersible particles being uncharged, the second dispersible particles being positively-charged electrophoretic particles, and the third dispersible particles being negatively-charged electrophoretic particles.

A reversible thermosensitive recording medium comprising an concealing layer provided between a reversible thermosensitive recording layer which is reversibly changed in its color by heat and a photo-thermal conversion layer which absorbs light with generating heat, wherein the concealing layer has an optical characteristic that the ratio of a light absorptivity of light having 555 nm wavelength, in comparison with a light absorptivity of laser light wavelength, is 80% or less. This reversible thermosensitive recording medium has a concealing layer to conceal the color of the photo-thermal conversion layer, thereby the visibility and the contrast of the obtained images are significantly improved, further more, durability in repeated used is also significantly improved.

A process for the production of lithographic printing plates, and a light-sensitive material for use in the process are described. The light-sensitive material comprises an electrically conductive support having a hydrophilic surface, and a positive type light-sensitive layer and a photoconductive insulative layer on the support, wherein the positive type light-sensitive layer and the photoconductive insulative layer are provided on the support as a unit layer or individually in that order, and the photoconductive insulative layer can be charged either positively or negatively. The desired lithographic printing plate can be prepared by treating the light-sensitive material by the simple process of the invention.
