A tensioning frame for tensioning a printing screen comprises struts to reinforce the constituent beams. These may be provided either on a supplementary brace plate or integrally formed with the beam. A shaft may be used to retain engagement bodies within pockets formed in the beam.

A tensioning frame (22) for tensioning a printing screen (3) comprises a plurality of elongate beams (30A-30D) which extend around the periphery of the printing screen (3) and define the tensioning frame (22), wherein at least one of the beams (30A-30D) comprises an opening (32) which is dimensioned to permit a printing screen (3) to be received therethrough, in a lateral direction (A). Mechanisms are described for engagement of the tensioning screen (22) and printing screen (3), as well as an apparatus and a method permitting the lateral loading of the printing screen (3).

Disclosed is a precision cut printing screen in which the features of a printing pattern are defined on a sheet material by a plurality of apertures within a target printing boundary. Also disclosed is a method of making the printing screen.

A numbering stencil assembly for painting numbers or words on a curb includes a frame that is positionable against an exposed face of a curb to define a painting area on the exposed face. A pair of first mating members is provided and each of the first mating members is coupled to the frame. A plurality of stencils is provided and respective stencils are positionable on the frame to facilitate words or numbers to be painted onto the exposed face of the curb. A plurality of second mating members is provided and each of the second mating members is coupled to a respective one of the stencils. Each of the second mating members on respective ones of the stencils releasably engages the first mating members on the frame when the respective stencils are positioned on the frame for retaining the respective stencils on the frame.

Disclosed is a printing screen assembly, a frame for a printing screen and method for their construction. The printing screen assembly has a frame (310) with an elongate first frame member (320, 320a) and an elongate second frame member (320, 320b) parallel to the first frame member (320, 320a) and in fixed relation thereto; and a corresponding cantilevered first and second tensioning arrangement (326) extending from each frame member (320) along a length thereof. A predictable pre-tensioning force may be applied by resiliently deflecting the tensioning arrangements (326) into contact with an abutment arrangement (328) and securing a printing screen to an attachment portion (326b) of the first tensioning arrangement (326a), while the first tensioning arrangement (326) is in contact with the first abutment arrangement (326a). The frame may be formed by preselecting the resilience of the tensioning arrangement (326) so as to preselect the tension applied when tensioning a printing screen in use.

A screen plate and a manufacturing method of the screen plate, provided for solving a problem of glass cement being thicker at the center and thinner at the border during printing glass cement by use of the screen plate in the prior arts and an inclination of burr generated at the borders. In the screen plate, a pattern layer comprises a plurality of openings, each of which comprises at least two sub-openings which have horizontal dimensions gradually decreasing in a vertical direction from a side close to the screen to a side away from the screen, so that a blade can squeeze the glass cement through a region of the screen corresponding to the sub-opening closest to the screen and further squeeze the glass cement through the plurality of the sub-openings having gradually reduced horizontal dimensions, thereby achieving a uniform output amount of the glass cement at the sub-opening farthest from the screen and eliminating the burr at the border of the printed pattern of the glass cement.

A printing screen and a sealant printing method are provided. The printing screen includes a frame, a mesh/screen fixed on the frame, and a film formed on the mesh. The portion of the mesh that is not covered by the film forms a feeding port in a rectangular ring shape. The rectangular ring includes two opposite first sides and two opposite second sides. The width of an upper opening of the cross section across the first sides is less than or equal to that of an upper opening of the cross section across the second sides. At a first height, the area of the cross section across the first sides is greater than that of the cross section across the second sides, the first height being less than the thickness of the film. The printing screen and the sealant printing method solve the problem of poor height uniformity of sealants.

The present invention relates to a self-aligning stencil device for producing a multi-color composite image on a target surface. The self-aligning stencil device includes a central panel and a plurality of stencil panels foldably connected to the central panel. The central panel includes a solid region and a cut-out region. The solid region of the central panel includes a front surface and a back surface, and is defined by an outer border of the central panel and an inner border of the central panel. The cut-out region is vacant space that is defined by the inner border of the central panel. Each stencil panel has its own distinct stencil pattern and is foldably connected to a different corresponding portion of the outer border of the central panel, thereby forming a connection fold between each stencil panel and its corresponding portion of the outer border of the central panel. The plurality of stencil panels, when folded at their connection folds upon the central panel, self-align to collectively form a composite image, so that painting each distinct stencil pattern with a different color is effective to yield a multi-color composite image on a region of the surface imposed behind the cut-out region of the central panel. Also disclosed are kits and methods for producing multi-color composite images using the device of the present invention.

Embodiments of the invention include a breast nipple areola complex tattoo stencil comprising first, second and third stencil sections. The first stencil section defines an areola area. The second stencil section defines a nipple area and tubercle areas. One or more registration elements on the first and/or second stencil sections enable registration of the second stencil section to the first stencil section. The third stencil section defines one or both of a nipple shading area and a nipple highlight area. One or more registration elements on the third and/or second stencil sections enable registration of the third stencil section to the second stencil section.

A method of screen printing an image on a substrate, such as rotary screen printing, includes using a printing screen having a surface structure at its printing side and attached imaged lacquer layer having open areas defining the image to be printed, where the image includes pixel based design elements, the printing screen has a parallelogram pattern, preferably an orthogonal pattern, of screen openings and the open areas of the imaged lacquer layer representing the pixel based design elements are arranged in an orthogonal raster.
