Provided are an inspection method, a program, an inspection device, and a printing device capable of realizing a uniform inspection in a defect inspection of a printed article using a special substrate. A method includes an imaging data acquisition step (S14) of acquiring imaging data (48) of a printed article using a special substrate, a non-printing region positional information acquisition step (S16) of acquiring information (44) for specifying a position of a non-printing region in the imaging data, the non-printing region corresponding to a substrate region of the printed article on which a pattern and a background of the pattern are not printed, an inspection step (S20) of specifying the non-printing region, analyzing the imaging data by applying a predetermined inspection rule (46), and performing an inspection of the printed article, and a notification step (S22) of performing a notification of an inspection result (50) and not performing a notification of an inspection result indicating that a defect is present in the substrate region of the printed article corresponding to the non-printing region.

A method for printing a marking on a golf ball includes arranging ink in an etching pattern on a printing plate, matching a reference position on the plate to a reference position on the golf ball, transferring the ink from the printing plate to a pad, and transferring the ink from the pad to the golf ball such that the golf ball includes the marking. The pattern includes an etch corresponding to the marking, wherein the etch differs from the marking in a manner dependent on the position of the marking on the golf ball. The marking that results on the golf ball is a linear marking, and a centerline of the linear marking lies entirely within a marking plane that is not a centerline plane of the golf ball, and wherein the edges of the marking are parallel with the marking plane.

Disclosed are methods that couple effective nesting of fabric, as part of a textile cutting process, in which designs and/or graphic elements are directly printed on the nested elements, instead of on the entire textile sheet. Embodiments of the invention can address issues of waste and redundant printing, such as by starting with a blank textile roll, and printing only in the geometry areas of the patterns. Embodiments of the invention can increase fabric yield, because there are no constraints between the pattern geometries and the textile sheet print.

According to aspects of the embodiments, there is provided a method of measuring the amount of fountain solution employed in a digital offset lithography printing system. Fountain solution thickness is measured using a glass roll at a lower temperature than the fountain solution. The lower temperature causes the fountain solution to undergo a change in state and in a solid state the fountain solution crystalizes and changes roll opacity with the thickness of the film. When radiated with a light source the opacity is continuously measured through the surface of the roller. The thickness of the crystallized fountain solution can then be determined via the opacity level increase by the crystallization and the impact to the opacity on the glass roll.

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.

A method for transferring and/or fixating a print on(to) a substrate includes feeding a substrate through a device for transfer and/or fixation for the purpose of transferring thereto and/or fixating thereon a print, where the substrate has been provided or is provided with a number of basic colours and optional dilutions thereof, comparing the basic colours and the optional dilutions thereof of the substrate to registered verification basic colours and optional dilutions thereof, and approving or not approving the substrate on the basis thereof, and/or comparing basic colours and optional dilutions thereof of a print paper, to be fed through with the substrate with a print to be transferred and said basic colours and optional dilutions thereof to registered print basic colours and optional dilutions thereof, and approving or not approving the print paper on the basis thereof.

A method of improved screening to increase stability in flexographic printing is provided. The method is performed by a flexographic printing system. The flexographic printing system includes a computer system and a flexographic printing device. The method includes analyzing the first proposed graphical input of the printing job to identify at least one highlight area containing a plurality of halftone graphical elements in the first proposed graphical input, determining an amount of white space between the plurality of the halftone graphical elements in the first proposed graphical input, assigning at least one graphical element to be placed in a spatial relationship with each of the plurality of the halftone graphical elements, generating a second proposed graphical input by placing the at least one graphical elements on the first proposed graphical input based on the respective assignment, and instructing the flexographic printing device to print the second proposed graphical input.
