PRINT TARGETS AND IMAGE ANALYSIS FOR FEEDBACK CONTROL OF FLEXOGRAPHIC PRINTING DEVICES
According to aspects of the embodiments, there is provided methods to measure characteristics of line width and density of printed test patterns. By printing the test patterns and capturing with an in-line scanner or optical device, the analytical results of these test patterns can be used as feedback to a control system that adjusts both impression and inking levels without the need of a skilled operator.
Electronic device, method and apparatus for producing an electronic device, and composition therefor
An electronic device, a method and apparatus for producing an electronic device, and a composition therefor are disclosed. An adhesive material is applied in a first pattern on a surface of a receiver substrate. A carrier having a metal foil disposed thereon is brought into contact with the first substrate such that a portion of the metal foil contacts the adhesive material. The adhesive material includes a first polymer, a second polymer, and a conductive carbon black dispersion, and is activated using at least one of mechanical pressure and heat while the portion of the metal foil is in contact with the adhesive material. The first substrate and the second substrate are separated, whereby the portion of the metal foil is transferred to the first substrate. The adhesive is electrically conductive to maximize the possibility of maintaining electrical connectivity even when there is a break in the metal foil.

Method for determining print parameters of a printing machine and test stand
A method for the determination of print parameters of a printing machine, particularly a flexographic printing machine, comprises the following steps: First, a print form (12) is provided and mounted on a print cylinder (14). Then, at least one high-resolution image of the surface of the print form (12) is recorded by means of a 3D camera (18). On the basis of the at least one high-resolution image a height profile of the print form (12) is determined and then a simulated print image is calculated on the basis of the height profile and an initial set of print parameters. Finally, optimized print parameters are determined by checking and/or varying the print parameters of the initial set. For this purpose, a simulated print image is calculated again after the print parameters have been varied. In addition, a test stand is specified on which such a method can be carried out.

Method of flexographically printing a plurality of lines
A method of flexographically printing a plurality of lines onto a substrate includes providing a flexo-master having a pattern of raised features including a plurality of lines. At least two of the lines intersect at a junction, wherein the junction includes one or more hollow voids. The flexo-master is used to apply ink onto the substrate forming a printed pattern including a printed junction corresponding to the junction on the flexo-master, wherein the printed junction has a different shape than the junction on the flexo-master.
