A method is described for radiation-cured relief printing onto containers, where at least two print layers are applied one on top of the other onto a container surface by way of an ink jet and are cured successively by way of irradiation in such a way that the print layers, in particular edge regions thereof, can run over one another and/or alongside one another. As a result, the height and contours of relief-like printed images can be adjusted flexibly and efficiently by radiation-induced limited smoothing.

A PTSM-coated expandable microsphere comprises a polymer shell enclosing an interior volume containing at least one blowing agent. The polymer shell has an outer surface with photothermal susceptor material disposed on at least a portion thereof. If heated to at least one temperature greater than 25° C., each of the expandable microspheres expands, but does not rupture, the polymer shell by a sufficient amount to at least double the interior volume. A markable comprises a substrate and a viewable layer secured thereto. The viewable layer comprises a binder material retaining the PTSM-coated expandable microspheres. A method of marking a markable article comprises imagewise exposing the PTSM-coated expandable microspheres of the markable article to at least sufficient electromagnetic radiation to cause the PTSM-coated expandable microspheres to expand thereby creating a predetermined image. A marked article preparable according to the method is also disclosed.

A method for producing a relief-like printed image on containers is described in which print layers are layered onto one another by way of jet application of a printing paint, an ink, a varnish, or an adhesive from at least one print head onto a container, thereby producing elevated regions of the printed image. Due to the fact that the print layers are each applied in full tone printing, optical and haptic effects can be created on container surfaces with low equipment complexity and a minimal number of printing steps.

A process includes printing a pattern on an upper surface of a substrate and curing to form a pattern layer; carrying out digital inkjet printing on an area where a convex pattern is required on the pattern layer by using a first UV varnish to obtain a first UV varnish layer, and before the first UV varnish layer is cured, in a crack area with a predetermined sharp boundary on the pattern layer, digital inkjet printing is performed on an edge of the first UV varnish layer with an ink to obtain an ink layer, the ink layer is in contact with the first UV varnish layer, then the first UV varnish layer is subjected to curing, the first UV varnish and ink being transparent or translucent and removing the ink to obtain a 3D texture decorative panel with sharp edges.

A method for preventing detachment of a three-dimensional object from a printing tray of a printing apparatus is disclosed. The method includes printing a carpet of building material below and around the base of a three-dimensional object to be printed; and printing said three-dimensional object. The portions of the carpet that protrude out of the boundaries of the base of the three-dimensional object are coated with one or more layers of support material to help keep the carpet flexible and adhesive in texture.

This invention discloses a braille plate for an elevator. The braille plate comprises a plurality of substrates, and a plurality of bump structures. In present invention, each substrate is formed on a body via crosslinking agent, and each of the bump structures is formed by at least one main layer. Furthermore, the body is an elevator decorative plate.

Flexible braille indicia signage and methods are provided. Preferably, the flexible braille indicia signage takes the form of braille directional identifiers for use on railings or the like. In one example, the braille indicia signage is made by providing a flexible substrate and printing a first layer of ink on a first side of the flexible substrate in a pattern defining desired braille indicia. Multiple layers of ink are then printed in registration with the pattern atop of the first layer of ink such that the desired braille indicia has a height of at least 0.6 mm (0.79 mm for braille directional identifiers) relative to the first side of the substrate. A sealing layer of ink is then printed atop the substrate and multiple layers of ink. The result is a braille sign with braille indicia that does not separate from the substrate on a condition that a portion of the substrate bearing the braille indicia is flexed in an arc of a 10 mm, i.e. 7/16 inch, radius circle, such as, for example, when the braille indicia sign is a braille directional identifier affixed to a railing having a 20 mm, i.e. ⅞ inch, or greater diameter.
