A laser system and method for inspecting a substrate and/or a laser score formed in a moving web of material during laser processing of the material with a laser processing system having a laser source for generating a laser beam and a lens for focusing the laser beam and reflecting the laser beam onto the advancing web of material where the focal point is directed a selected location on the web to produce the score in the advancing web of material, the score having a depth less than the thickness of the material and measuring the depth at one or more locations on the advancing web of material concurrent with producing the score line and where the material may be a packaging material and the score provided for easy opening of the packaging.

An adhesive containing at least one selected from the group consisting of a urethane prepolymer and a polyol, a polyisocyanate, a polymerizable (meth)acrylate compound, and a photopolymerization initiator is disclosed. A heat-sensitive screen master and a method for producing a heat-sensitive screen master are also disclosed.

A screen-printing screen for printing electrically conductive patterns on glass sheets, includes a main mask, the aperture size of the main mask being larger in a lateral portion than in the central portion, the screen furthermore including, in at least one double-mask zone, located in the central portion, at least one secondary mask fastened to a face of the main mask, the aperture size of the or each secondary mask being larger than the aperture size of the main mask in the central portion, and the mesh of the or each secondary mask making, with the mesh of the main mask, an angle α comprised between 1 and 89°.

A photosensitive stencil includes a porous stencil carrier that can be a sheet of woven material with crisscrossing filaments. The stencil carrier is coated with a photopolymer emulsion that is water based to form a stencil blank. In use, a light mask is disposed atop the stencil blank. The light mask can be contained on a sheet of paper or a transparent film. Alternatively the stencil blank is fed through an inkjet printer and the light mask is printed directly onto the stencil blank using common inks. The stencil blank is then exposed to light for a few minutes, which cross-links the photopolymer emulsion in unmasked regions. After exposure, the stencil blank is developed by being washed out with water. The water removes emulsion and adhesive, where present, within areas that were masked by the light mask, revealing open or open regions through which ink or paint can be applied.

A printing method that carries out printing using a mesh screen, which is a screen gauze including multiple holes, is provided. The printing method includes: a covering process of covering one surface of the mesh screen with a covering member; an entering process of entering the covering member to at least a middle of the hole from a side of the one surface with respect to the multiple holes of the mesh screen; a mask forming process of ejecting a mask forming liquid used to form a mask that covers one part of an other surface of the mesh screen from an ejection head, to form the mask; a peeling process of peeling the covering member from the mesh screen; and a print executing process of printing an image corresponding to a pattern of the mask on the medium using the mesh screen and the printing ink.

A method of fabricating a casing including steps of providing a polycarbonate substrate, printing a first material on the polycarbonate substrate to form a light shielding layer by using a first screen, and printing a second material on the light shielding layer to form a light transmission layer by using a second screen is provided. The light shielding layer has at least one patterned transmissive region. The light transmission layer covers the at least one patterned transmissive region and a portion of polycarbonate substrate exposed by the at least one patterned transmissive region. Mesh counts of the first screen is greater than that of the second screen. A casing including a polycarbonate substrate, a light shielding layer, and a light transmission layer is provided. A thickness of the light transmission layer is greater than a thickness of the light shielding layer. An electronic device adopting the casing is provided.
