20080202364 | Means of attaining large screen print area with new squeegee design - An adjustable variable pressure squeegee for screen printing includes a holder having a compliant member coupled to a retainer member and a squeegee blade having an edge coupled to the retainer member. | 08-28-2008 |
20100132568 | Screen printing system and method of screen printing - A screen printing system includes a screen made of a porous material and an adjustable variable pressure squeegee having a squeegee blade. The squeegee blade has a first edge for contacting the screen and pushing an ink medium deposited on the screen through a print area of the screen. The squeegee blade has a second edge retained in a holder. The holder has a compliant member configured to distribute a downward force applied to a point on the compliant member along a length of the squeegee blade in order to maintain contact between the first edge and the screen along the length of the squeegee blade. | 06-03-2010 |
20110209634 | Method of Screen Printing on 3D Glass Articles - A method of screen printing on 3D glass articles includes providing a 3D glass article having a first 3D surface with a first surface profile and a second 3D surface with a second surface profile, the first 3D surface and the second 3D surface being separated by a thickness of glass. The method includes providing a fixture having a 3D fixture surface with a fixture surface profile matching the second surface profile. The method includes providing a screen having a design, a squeegee, and an ink. The 3D glass article is supported on the fixture by mating the second 3D surface with the 3D fixture surface. The screen is positioned at a plane a distance above the first 3D surface. The ink is deposited on the screen. The squeegee is positioned at a selected orientation relative to the plane. The ink is pushed through the screen onto the first 3D surface by simultaneously contacting the squeegee with the screen, traversing the squeegee in a linear direction, maintaining the orientation of the squeegee relative to the plane, locally deflecting the screen from the plane to the first 3D surface, and locally conforming the screen to the first surface profile. | 09-01-2011 |
20140151329 | FOAM ETCHANT AND METHODS FOR ETCHING GLASS - A foam acid glass etching media including a solvent; a source of fluorine; and a nonionic surfactant. The foam acid is in the form of a colloidal dispersion with a gas dispersed in a continuous liquid phase. The media is useful in etching or polishing glass sheets in a batch or continuous process. Described is a method for etching or polishing glass by providing a glass having at least one major surface; and contacting the at least one major surface with a foam acid. | 06-05-2014 |
