The present invention relates to a precision overprinting method of printed electronics rotary printing where a location can be adjusted in real time. More particularly, minute precise printing electronic patterns of a micrometer level which are multilayered by a plurality of gravure offset printing units are accurately overprinted, and a fine deviation in a rotation direction and an axial direction of a plate cylinder is quickly solved. The present invention also relates to a precision overprinting method of printed electronics rotary printing where a location can be adjusted in real time, capable of verifying a printing quality by displaying register marks printed in printing units and alignment state on a display device.

The present invention relates to a luminous advertisement sheet. The luminous advertisement sheet includes a light-transmitting print sheet having an EL advertisement region formed in at least one area of the print sheet, and a general advertisement region formed in the other area thereof. The EL advertisement region has at least one of a fixed pattern portion in which a transparent electrode layer, an EL layer and a dielectric layer are sequentially laminated and a variable pattern portion in which a transparent electrode layer, an EL layer, a dielectric layer and a plurality of pixel electrode layers are sequentially laminated. The general advertisement region allows general dye printing to be performed therein. The luminous advertisement sheet further includes a pattern electrode layer laminated and printed with a conductive ink material to have a predetermined luminous pattern in at least one area of the dielectric layer laminated in the fixed pattern portion and/or the variable pattern portion. Accordingly, there are provided a luminous advertisement sheet that exhibits excellent advertisement effects and can be easily produced in a multi-line small-batch production manner and at remarkably reduced manufacturing costs, and a method of manufacturing the same.

The present invention provides a printing head for nano patterning including a manifold for accommodating a liquid printing material, a cartridge with an injection chamber communicating with the manifold, and a sample holder for patterning installed outside the injection chamber of the cartridge. The printing head comprises a shadow mask which is installed outside the injection chamber to be finely moved in an X-Y direction and has a single injection hole with a relatively very small size; an actuator for finely moving the shadow mask; an injection-inducing unit including a high voltage generator, a power supply electrode that is installed within the injection chamber and receives power from the high voltage generator to generate positive charges, and an opposite electrode for generating negative charges on the sample holder in a state where the shadow mask is interposed between the power supply electrode and the opposite electrode, thereby generating induced discharge from the injection chamber toward the sample holder; and a control unit for controlling the driving of the actuator so that the injection hole of the shadow mask can be moved to patterning positions corresponding to patterning data input in advance. According to the present invention, patterning accuracy can be improved, ultra-fine patterning and patterning of arbitrary shapes can be achieved, and a configuration for injecting the printing material can be simplified.

Disclosed herein is a method for forming a pattern, comprising: attaching a single-layer or multi-layer dry film resist made of a semi-solid or solid material to part or all of the surface of a substrate; exposing the dry film resist to light either by irradiating a focusable energy beam directly onto the resist or by projecting a specific wavelength range of light onto the resist, to form a region to be filled with a functional material; charging the functional material into the formed region using a method such as inkjetting; drying the functional material; and removing the dry film resist, thus obtaining the desired pattern.

Disclosed herein is a method of forming a pattern, comprising: attaching a single-layer or multi-layer sacrificial film made of a semi-solid or solid material on part or all of the surface of a substrate; irradiating the sacrificial film with a focusable energy beam such as a laser beam to form a region to be charged with a functional material; charging the functional material into the formed region using a method such as an inkjet; drying the functional material; and removing the sacrificial film, thus obtaining the desired pattern.
