Described herein are molecular inks, methods for printing the molecular inks on flexible substrates, and methods for forming printed electronic elements, such as resistive heaters, force sensors, motion sensors, and devices that include these elements, such as force responsive conductive heaters. The methods include printing a molecular ink on a flexible substrate that is heated to 30° C. to 90° C. before and/or during the printing process and curing the substrate to produce a conductive pattern thereon. The molecular inks generally include a particle-fee metal-complex composition formulated from at least one metal complex and a solvent, and optionally, a conductive filler material, and/or surfactant.

The present invention provides a quantum dot display panel and a manufacturing method thereof. The present invention includes a pixel definition layer on a surface of a color film substrate, a quantum dot photoconversion film located on pixel definition regions of the pixel definition layer, and a blue light display device located under the quantum dot photoconversion film. An uplift layer and a light-shielding layer are arranged in the pixel definition layer to ensure that a thickness of the pixel definition layer is greater than or equal to 6 μm, which is beneficial to uniform curing of quantum dots in the quantum dot photoconversion film.

An ink jet recording method is a method in which a cyan ink, a magenta ink, a black ink, and a yellow ink radiation that are curable inks are ejected from ink jet heads to attach the radiation curable inks to a recording medium. The method includes, in this order, a first step of attaching the cyan ink, the magenta ink, and the black ink onto the recording medium and applying temporary curing radiation to the recording medium and a second step of attaching the yellow ink onto the recording medium and applying full curing radiation to the recording medium without applying the temporary curing radiation.

A process for printing multiple layers on a fabric or other material using UV-curable ink that includes a step of printing a first layer on the material and another step of partially curing the first layer. A next step includes printing a partially UV-transparent layer over the first layer and fully curing the UV-transparent layer while simultaneously fully curing the first layer.

A method for manufacturing an electromagnetic shielding film of reduced thickness and a simplified manufacturing process includes forming a conductive ink layer by inkjet printing, on a component to be shielded, forming an insulative ink layer on the conductive ink layer by inkjet printing, and sintering the conductive ink layer and the insulative ink layer to form an electromagnetic shielding layer and an insulative layer, thereby obtaining the electromagnetic shielding film.

The invention relates to a process for the manufacture of polymer film graphics comprising providing a continuous substrate having a release layer thereon; applying an image layer in the shape of a graphic letter or design to the release layer; depositing an adhesive layer to the image layer and which has the same shape as the image layer graphic letter or design; curing the adhesive and image layers; and winding the polymer film graphics onto rolls. The invention further relates to a polymer film graphic comprising a substrate having an upper surface and a lower surface; a release layer overlying the upper surface of the substrate; an image layer in the shape of a graphic letter or design overlying the release layer; an adhesive layer overlying the image layer, the adhesive layer having the same shape as the image layer graphic letter or design.

Apparatus, compositions, and systems for ultraviolet (UV) heat-activated laminating adhesives applied via an inkjet printing process are disclosed. A system includes a first inkjet mechanism configured to deposit ink in a particular pattern onto a surface of a rigid medium. A second inkjet mechanism is configured to deposit a laminating adhesive onto the particular pattern printed on the surface of the rigid medium. A pair of stainless steel plates is configured to receive an overlay film layer and the laminating adhesive deposited onto the particular pattern printed on the surface of the rigid medium. The overlay film layer is positioned such that a surface of the overlay film layer faces the laminating adhesive. Pressure and heat are applied to the overlay film layer and the laminating adhesive to laminate the particular pattern printed on the surface of the rigid medium.

An ink jet method records a radiation-curable ink composition containing a polymerizable compound. The radiation-curable ink composition includes a first ink composition and a second ink composition. The ink jet method includes a first discharging step of discharging the first ink composition with an ink jet head to adhere the composition to a recording medium, a first curing step of irradiating the first ink composition adhered to the recording medium with radioactive rays, a cooling step of cooling the recording medium, a second discharging step of discharging the second ink composition with the ink jet head to adhere the composition to the cooled recording medium at least in a part of the region where the first ink composition adhered; and a second curing step of irradiating the second ink composition adhered to the recording medium with radioactive rays.

The invention relates to a device for printing on edge bands including at least one printhead for producing a printed image on the edge band; a linear drive for moving the at least one printhead in a printing direction within a printing region between two end positions; a feeding apparatus for feeding the edge band into the printing region in a transport direction; and a control apparatus for controlling the at least one printhead, the linear drive and the feeding apparatus. The technical problem of technically and economically improving the process of printing on edge bands is solved in that the transport direction of the edge band is oriented substantially parallel to the printing direction. The invention further relates to a method for printing on edge bands.

The present disclosure relates generally to signal encoding for flexographic printing plates. One aspect is a flexographic, photopolymer printing plate having transparent layers to allow encoded signal printed or laser ablated thereon to be detectable from both sides of the printing plate. Another aspect is a flexographic, photopolymer printing plate having an encoded signal formed in a photocured layer. Still another aspect is a system for tracking such printing plates, including managing location, print impression count, location tracking, etc. Other aspects are described as well.
