The panel surfaces of the respective panels collectively comprise the outer substrate surface of the cover. A surface texture is disposed upon and additively applied to the outer substrate surface. The surface texture is disposed on the respective panel surfaces in customizable, panel-specific, predefined panel arrangements. The surface texture defines surface profile that includes an alternating and repeating series of land areas and raised portions, wherein each raised portion is positioned between a plurality of land areas. The raised portions extend from the outer substrate surface and are formed from a dimensional ink, wherein each of the plurality of raised portions has a terminus that is spaced apart from the outer substrate a height of greater than about 0.05 millimeters (mm).

A sports ball having a cover with an outer substrate surface is provided. The cover includes a plurality of raised lenticular features each having a terminus and a plurality of land areas. The raised lenticular features are formed from dimensional ink and disposed upon and extend from the outer substrate surface, such that each terminus is spaced apart from the outer substrate surface by a height greater than about 0.05 millimeters. The cover, including raised lenticular features and the land areas, defines a plurality of directionally-based designs within the physical surface geometry thereof, such that a first design is visible when the sports ball is viewed from a first viewing angle, a second design is visible when the sports ball is viewed from a second viewing angle, and a third design is visible when the sports ball is viewed from a third viewing angle.

There is described a combined printing press (10; 10*) for the production of security documents, in particular banknotes, comprising a screen printing group (2; 2*) and an intaglio printing group (3) adapted to process substrates in the form of individual sheets or successive portions of a continuous web. The screen printing group (2; 2*) is located upstream of the intaglio printing group (3) and comprises at least one screen printing unit (20; 20*) designed to print a pattern of optically-variable ink onto one side of the substrates, which optically-variable ink contains flakes that can be oriented by means of a magnetic field. The screen printing group (2; 2*) further comprises a magnetic unit (24; 24*) located downstream of the screen printing unit (20; 20*), which magnetic unit is designed to magnetically induce an optically-variable effect in the pattern of optically-variable ink applied by the screen printing unit (20; 20*). The screen printing group (2; 2*) further comprises at least one drying/curing unit (25, 28; 25*, 28*) designed to dry/cure the pattern of optically-variable ink in which the optically-variable effect has been induced by the magnetic unit (24), prior to transfer of the substrates to the intaglio printing group (3).

A method for screen printing, including: by using a screen printing apparatus provided with a screen printing plate having an opening part corresponding to a printing pattern, a scraper, and a squeegee, filling a paste supplied on an upper surface of the screen printing plate into the opening part of the screen printing plate by the scraper; and, after that, pushing out the paste to a predetermined position of an object to be printed from the opening part of the screen printing plate by the squeegee to screen-print the paste corresponding to the printing pattern on the object to be printed, wherein the humidity in the screen printing apparatus is adjusted during the screen printing. As a result, by controlling an amount of moisture in the paste on the screen printing plate, a screen printing method is capable of improving the printing property of the paste.

A manufacturing method of flexible substrates via a screen printing machine includes moving the back-ink blade and the scraper, the scraper is above the back-ink blade, and the back-ink blade is configured to coat the adhesive material on the opening; moving the back-ink blade and the scraper along an opposite direction, the scraper is lowered down to a position below the back-ink blade, the scraper prints the adhesive material from the opening to the substrate so as to form a flexible substrate thin-film corresponding to the opening area on the substrate; and applying a baking process on the flexible substrate thin-film to obtain a cured flexible substrate. The screen printing machine forms the flexible substrate thin-film corresponding to the opening of the screen printing machine to so as to obtain the flexible substrate having a predetermined dimension, which simplifies the manufacturing process and saves the manufacturing cost.
