Abstract:
A method and apparatus for making color filters for liquid crystal display panels. A transfer layer is formed on a collector roll, and a raised pattern corresponding to the desired black matrix pattern is formed on the transfer layer by embossing. A plurality of colored ink patterns is formed in the appropriate location within the boundaries formed by the raised pattern, thereby forming the multicolor image that will become the color filter. This multicolored image is then transferred to the substrate. Preferably, the inks are deposited into the black matrix pattern using typographic imaging pins which are smaller than the cells of the black matrix pattern.
Abstract:
A printing apparatus applies ink to a surface of a printing plate in the shape of a predetermined pattern and then transfers the ink to a substrate. The printing apparatus includes: an image recording section that applies the ink to the surface of the printing plate; a plate surface observation unit that acquires information about the surface of the printing plate; a storage section that stores information about a reference shape serving as a reference of the surface of the printing plate; and a determination section that compares the information about the reference shape stored in the storage section with the information about the surface of the printing plate, which is obtained by the plate surface observation unit, and determines whether or not the surface of the printing plate to which the ink has been applied is present in a predetermined range of the reference shape.
Abstract:
A printing technology wherein an endless belt-shaped printing plate is wound about a plate cylinder and a guide roller of a printing cylinder and, by using the printing plate, a continuous form sent between the printing plate and an impression cylinder is printed. In the plate cylinder, feed pins are disposed in rows at an even pitch along an outer periphery of the cylinder. The feed pins are guided by a fixed cam ring and project and retract freely and project in a desired region of the plate cylinder, respectively with respect to the cylinder surface. Pin feed holes are provided in rows in marginal zones of the endless belt-shaped printing plate. The endless belt-shaped printing plate is formed by joining and bonding both ends of an elongated resinous relief printing plate with an adhesive tape from the printing surface side. The pin feed holes are engaged with the feed pins of the plate cylinder, whereby the plate feed is guided.

Abstract:
Apparatus comprises transfer means (14; 32; 54) suitable for coming into contact with a shaped surface (2′; 55, 58) of an item (1′; 44; 44′) to transfer thereupon a fluid material (7, 7′) and applicator means (19; 38) suitable for applying said fluid material (7, 7′) onto said transfer means (14; 32; 54), said transfer means (14; 32; 54) being deformable in such a way as to be able to adapt itself according to said shaped surface (2′; 55, 58). Method for decorating an item (1, 1′) comprises distributing onto said item (1, 1′) a polymeric base layer means (3), applying onto said base layer means (3) a decorative pattern defined by decorating means (4, 7, 7′) in liquid form, fixing said decorative pattern to said item (1, 1′), said fixing comprising anchoring said decorating means (4, 7, 7′) to said base layer means (3), without applying to said item (1, 1′) further fixing layers.
Abstract:
The present invention is directed to a pad for carrying liquid having a piece of non-woven material wherein the piece of material is capable of absorbing an amount of the liquid at least about 1.5 times the weight of the piece of material, a first printed ink on a first surface of the material, and a second printed ink on either the first or a second surface of the material, and wherein the first ink is substantially in register with the second ink. The present invention is also directed to a method for making a printed pad for carrying a liquid including the steps of feeding a web of non-woven material into a rotogravure press, wherein the material is capable of absorbing at least about 1.5 times its own weight of the liquid, printing a first ink with the press on a first surface of the web, printing a second ink with the press substantially in register with the first ink on the first surface or a second surface of the web. The present invention is also directed to a system for cutting printed designs from a web of elastic material to form printed pads wherein the printed designs are printed on the web at a repeat length having a braked unwind station having a variable braking tension; an infeed station having an adjustable speed; a diecutter having a diecutting cylinder and a cylinder correction gearbox capable of correcting the position of the diecutting cylinder in a positive or negative rotational direction, wherein the circumference of the diecutting cylinder is greater than the repeat length; a first sensor for sensing the position of the printed designs on the web; a second sensor for sensing the position of the diecutting cylinder; a processor electronically coupled to the first sensor, the second sensor, the infeed station and the diecutter for controlling the infeed station and the diecutter in response to signals received from the sensors, wherein the processor sends a correction signal to the diecutting cylinder in response to signals from the sensors, the processor comprises a first counter for counting the number of consecutive corrections of the diecutting cylinder in the same direction and sending a correction signal to the infeed station when a predetermined number of consecutive corrections of the diecutting cylinder is reached.

Abstract:
The invention relates to methods and apparatus useful for making color filters for liquid crystal display panels. A multicolored ink pattern is deposited to a substrate while in a deformable state, flattened during the deposition process, and the deformed, more uniform shape of the printed dot is thereafter retained, preferably by curing during deposition. The transfer layer is preferably formed on a collector roll. A plurality of colored ink patterns is then transferred to the collector roll, preferably from a single pattern roll having multiple patterns thereon, to form the multicolor image that will become the color filter. This multicolored image is then transferred to the substrate.
