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.

A method of manufacturing a wood stain display sample includes optically scanning a wood sample including a wood stain with a computing device to generate a digital image of the wood stain. The method includes altering the digital image by adjusting a color of one or more portions of the digital image to correlate the color of the one or more portions to a color gamut of a xerographic printing process to form a color-adjusted digital image. The method includes printing the color-adjusted digital image to a substrate using a xerographic printing process to form the wood stain display sample. The printing includes printing an underlay toner to the substrate. The underlay toner includes a white or a transparent color. The printing includes printing a yellow, magenta, cyan, and black toner over the underlay toner. The printing includes printing an overlay toner to the black toner.

A security document includes a first ink layer and a second ink layer. The first ink layer includes a first color in a first color zone and a second color in a second color zone offset from the first color zone in a first direction, and a first blended color including a mixture of the first and second colors in a first blended color zone between the first color zone and the second color zone. The second ink layer includes a third color in a third color zone and a fourth color in a fourth color zone offset from the third color zone in a second direction, and a second blended color including a mixture of the third and fourth colors in a second blended color zone between the third color zone and the fourth color zone. The first direction is different than the second direction.

The present invention provides a method for applying multiple ink and/or coating layers on a substrate. At least one of the ink and/or coating layers contains one or more photoinitiators, and at least one of the ink and/or coating layers does not contain any photoinitiators. In certain embodiments, all of the ink and/or coating layers are wet trapped and the entire print construct is cured by exposure to UV radiation after all of the ink and/or coating layers have been applied. In certain embodiments, the wet trapping method of the present invention can be used to prepare laminates.

An object of the present invention is to provide an active energy ray-curable lithographic printing ink set that is excellent in superimposition of inks, and a method for producing a printed material using the same.

The present invention is an active energy ray-curable printing ink set including at least one ink of black or chromatic color including at least any one of a black pigment, a cyan pigment, a magenta pigment, and a yellow pigment, and a white ink including a white pigment, wherein at least one of the ink of black or chromatic color is the black/chromatic ink (1) having a tack value of 5.0 or more and 12.0 or less at 400 rpm measured with an inkometer at 38 C., and the white ink has a tack value of 1.0 or more and 5.0 or less at 400 rpm measured with an inkometer at 38 C.
