Various variable gloss reduction techniques are disclosed. In one embodiment, a gloss reduction technique is disclosed using a textured roller and a wiper impregnated with fuser oil to create a differential gloss pattern that reduces the gloss of an image printed on a substrate. In one embodiment, a gloss reduction technique is disclosed using a combination of heat and pressure to create a differential gloss pattern that reduces the gloss in specific regions of an image printed on a substrate. In one embodiment, a gloss reduction technique is disclosed using a differential gloss pattern to generate a security mark on a printed image to prevent against copying or fraudulent misrepresentation of the image.

The present disclosure relates to a liquid electrophotographic composition comprising: a polymer resin comprising a side group comprising a cross-linkable moiety; and a carrier liquid.

There is disclosed an image post-processing method for adjusting glossiness of a fixed toner image. The method includes a glossiness control step and a temperature control step. The glossiness control step is a step of, to a toner image formed of a toner containing a light absorbing compound and fixed to a recording medium, emitting glossiness control light so as to reduce or increase glossiness of the toner image. The temperature control step is a step of heating the toner image immediately before the light is emitted to the toner image such that the toner image has a surface temperature which is at least 20 C. lower than a softening temperature of the toner. The glossiness control light has a maximum emission wavelength in a wavelength range in which the compound absorbs light and is made to at least reduce the glossiness of the toner image.

There is disclosed an image post-processing method for adjusting glossiness of a fixed toner image. The image post-processing method includes a glossiness control step of, with a non-contact heating device, heating a toner image fixed to a recording medium so as to reduce glossiness of the toner image. The non-contact heating device is configured to heat the toner image fixed to the recording medium to a temperature which reduces the glossiness of the fixed toner image.

Provided is an image post-processing method for controlling a glossiness of a fixed toner image, the method including a glossiness control step of: irradiating the fixed toner image formed with a toner containing a compound that absorbs light and fixed on a recording medium with a glossiness control light that is capable of at least reducing a glossiness of the fixed toner image, wherein the glossiness control light has a maximum emission wavelength in a wavelength region which is absorbed by the compound.

An image processing apparatus includes a first obtaining unit obtaining color signals representing colors of an image, a second obtaining unit obtaining a gloss signal representing image gloss, a third obtaining unit obtaining a predetermined amount of a recording material, a first determination unit determining a recording amount of glossy recording material recorded in a first region, a second determination unit determining recording amounts of colored recording materials recorded in the first region such that a total amount of the recording amount of the glossy recording material recorded in the first region and the recording amounts of the colored recording materials recorded in the first region does not exceed the predetermined amount, and a third determination unit determining recording amounts of colored recording materials recorded in a second region based on the color signals and the recording amounts of the colored recording materials.

An information processing apparatus includes a display and a controller. The display displays an image. The controller controls the display to display a color setting section that sets information regarding a selected color selected from among multiple predetermined colors, and an effect presenting section that presents visual effect information representing a visual effect of the selected color.

An image forming system includes an image forming unit, a varnish coating unit, a reception unit, and a control unit. The image forming unit executes an image forming process of forming an image on types of recording media including a first type of recording medium with a coated layer and a second type of recording medium without a coated layer. The varnish coating unit executes a varnish coating process of varnish coating a recording medium on which an image is formed by the image forming unit. The reception unit receives a printing job from a user. The control unit controls the varnish coating unit. When the printing job received by the reception unit is a printing job for executing the varnish coating process on the second type of recording medium, the control unit controls the varnish coating unit to prevent the varnish coating unit from executing the varnish coating process.
