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.

The invention provides dispersed inorganic mixed metal oxide pigment compositions in a hydrocarbon media utilizing a dispersant having polyisobutylene succinic anhydride structure reacted with a non-polymeric amino ether/alcohol to disperse a mixed metal oxide pigment in the media. The metal oxide pigment is of the type used to color ceramic or glass articles. A milling process using beads is also described to reduce the mixed metal oxide particle size to the desired range. A method of using the mixed metal oxide dispersion to digitally print an image on a ceramic or glass article using the dispersion jetted through a nozzle and subsequently firing the colored article is also described.

A producing method of a base member provided with a printed layer, the method including: disposing a printing plate including a screen plate having an opening pattern and a frame body supporting the screen plate so that the printing plate is opposed to a printing target surface of the base member having at least one bent portion; disposing a squeegee so as to be opposed to a plate surface of the screen plate opposite to the base member; and forming the printed layer by extruding a printing material onto the printing target surface by the squeegee via the opening pattern of the screen plate in a state where the frame body is supported so as to be relatively movable with respect to the printing target surface in a normal direction of the printing target surface.

A printing device for building material articles, comprises a tank (2) for a printing material, solid or liquid, to be dispensed, an outlet mouth (3) suitable for dispensing the printing material onto a work surface, a conduit (5) extending along its own main direction (A) between the tank (2) and the outlet mouth (3), in which the conduit (5) comprises at least one deformable wall (6) movable between an operating position, in which it determines the creation of a restriction in the conduit (5) preventing the flow of the printing material towards the outlet mouth (3), and a rest position, in which it allows the flow of the printing material towards the outlet mouth (3).
