Abstract: Disclosed are a multi-optical-color optically-variable printing device (10) and a printing method thereof, and a readable storage medium. The multi-optical-color optically-variable printing device comprises: a conveying unit (100); a screen printing unit (110), used for printing an ink or a varnish containing a magnetic substance on a printing stock (500); and a plurality of optical-color optically-variable pattern forming units. Each optical-color optically-variable pattern forming unit comprises: magnetizing rollers (130), magnetic orientation components (132) being arranged on each magnetizing roller and used for performing magnetic orientation on the printing stock; and pre-drying and curing devices (160), used for pre-drying and curing the printing stock, each pre-drying and curing device comprising optical mask curing devices (230), the optical mask curing device being fixedly arranged and used for projecting dynamically refreshable variable optical field image-text, and the variable optical field image-text and the printing stock synchronously moving a predetermined distance. The multi-optical-color optically-variable printing device can complete omni-directional merging, i.e., merging in any direction, of fixed and variable multi-optical-color optically-variable image-text.

Abstract: Disclosed is a heat-sensitive recording material comprising at least an undercoat layer and a heat-sensitive recording layer in this order on a support,
the undercoat layer containing hollow particles and a binder,
the heat-sensitive recording layer containing a leuco dye and a developer,
the heat-sensitive recording material containing a compound represented by the following formula (1) as a first developer of the heat-sensitive recording layer:
wherein R 1 to R 5 are the same or different, and each represents a hydrogen atom, a halogen atom, a nitro group, an amino group, an alkyl group, an alkoxy group, an aryloxy group, an alkylcarbonyloxy group, an arylcarbonyloxy group, an alkylcarbonylamino group, an arylcarbonylamino group, an alkylsulfonylamino group, an arylsulfonylamino group, a monoalkylamino group, a dialkylamino group, or an arylamino group,
the heat-sensitive recording material satisfying either the following requirement (A) or (B):
(A) the undercoat layer contains an inorganic pigment I, and the heat-sensitive recording layer contains a pigment with an oil absorption of 130 ml/100 g or less as an inorganic pigment II; or
(B) the heat-sensitive recording layer contains 5-(N-3-methylphenyl-sulfonamide)-N',N''-bis-(3-methylphenyl)-isophthalic acid diamide or N-[2-(3-phenylureido)phenyl]benzenesulfonamide as a second developer, and the second developer is contained in an amount of 0.4 to 2.5 parts by mass per part by mass of the first developer.-

Abstract: There is provided with an image forming apparatus. A deciding means decides a discharge amount of a reaction liquid based on a timing at which the reaction liquid is discharged onto a print medium by the image forming apparatus, a timing at which each of inks of not less than two colors is discharged onto the print medium next to the reaction liquid, and a discharge amount of each of the inks of the not less than two colors by the image forming apparatus. A controlling means controls discharge of the reaction liquid and the inks of the not less than two colors.

Abstract: A liquid discharge apparatus (10) includes: a head (34) having a nozzle surface (33A) in which a nozzle (33) is opened; a wiper (72) configured to come into contact with the nozzle surface and move relative to the head; and a controller (130). The controller is configured to execute: a viscosity determination process of determining viscosity of liquid adhering to the nozzle surface; and a wiping process in which the wiper comes into contact with the nozzle surface and moves relative to the head. In a case in which the determined viscosity is lower than first viscosity indicating that the liquid is substantially solidified, a pressing pressure when the wiper comes into contact with the nozzle surface in the wiping process is set to be larger than a stress due to viscous friction of the liquid on the nozzle surface.
