This disclosure describes substrate(s) formed with a three-dimensional (3D) feature thereon, and method(s) of printing the same. One method includes identifying a plurality of locations on a substrate surface where the three-dimensional feature will be formed, determining a height value of the three-dimensional feature at each location, assigning a grayscale value to each location based on the height value, and applying ink to the substrate surface at each location according to the assigned grayscale value.

A printing process for a metal container includes the steps: Heating the metal container, in particular formed as a metal bottle ready for filling, to a pre-treatment temperature lying in an interval between 100° C. and 250° C., cooling the metal container to a temperature below 100° C., locally activating a printing zone, formed on an outer surface of the metal container to increase a surface energy of the printing zone and/or locally heating the printing zone to a printing temperature which is in an interval between 30° C. and 70° C., printing the printing zone with a printing method.

A printing process for printing with ink an image on an antimicrobial medical glove formed by a dipping process, wherein the image is first printed on a former and transferred to the glove during dipping.

Various of the disclosed embodiments concern printing systems configured to deposit flexible dye sublimation inks onto flexible transfer materials. Together, the flexible ink and transfer material allow images to be transferred onto complex-shaped, i.e. non-planar, surfaces of a substrate. The flexible ink may be, for example, a thermoformable UV dye sublimation ink or a superflexible UV dye sublimation ink. In order to transfer an image onto the substrate, the transfer material is pressed onto the surface of the substrate. The substrate, transfer material, or both are heated to a temperature sufficient to cause the ink to sublimate. During the sublimation process, dye is able to permeate the substrate and form a transferred image. The flexible ink formulation may also include a soluble or solvent-sensitive component. In such embodiments, a solvent can be jetted onto the substrate and/or transfer material to remove residual ink.

A method for printing on at least partially transparent containers, wherein, in a first printing step, a first printing image is printed onto the container by the application of at least one printing ink, and wherein, in a second printing step, a second printing image is printed onto the container by the application of at least one printing ink, wherein the printing images are printed at least partially covering one another, and specifically in such a way that ink layers are applied in a temporal offset sequence onto the container, wherein a first ink layer is allocated to the first printing image and a second ink layer is allocated to the second printing image, and that between the first and second printing image a reflection layer is at least partially provided, by means of which the printing images are at least partially optically separated from one another.

This disclosure describes substrate(s) having a three-dimensional (3D) feature formed thereon and methods of forming the features. One method involves applying a first layer of UV-curable material on a surface of the glass container around a circumference of the container and curing the first layer of UV-curable material to produce a first cured material layer that forms at least a portion of a first 3D feature. The method further comprises applying a second layer of UV-curable material on the surface of the glass container, spaced apart from the first 3D feature, around the circumference of the container, and curing the second layer of UV-curable material to produce a second cured material layer that forms at least a portion of a second 3D feature. The portion of the glass container between the first and second 3D features has a circumference less than that of the first or second 3D features.

The invention relates to a non-contact printing method and system as well as to a printed sensor. The method includes the steps of disposing a substrate (130) between a discharge electrode (110) and a printing material (140) such that the substrate (130) is spaced apart from the printing material (140); and activating the discharge electrode (110) to generate an electric field between the substrate (130) and the printing material (140), wherein the printing material (140) moves onto a surface (132) of the substrate (130) when the electric field attracts the printing material (140) to the surface (132) of the substrate (130). A corresponding printing system and printed sensor are also provided.

A method for safely differentiating a three dimensional object subsequent to its creation and varnish protection by means of applying and sealing a decoration and/or data between the original and a final varnish layers. The three dimensional object may be decorated and/or contain data from its original manufacturing process but it may also be protected by a varnish prior to utilizing this process. The method enables the addition of decoration and data at any time or location subsequent to the original manufacturing process. The process takes place on top of the original varnish and may be subsequently sealed by applying another varnish layer.

A method for inkjet printing an image onto a curved region of an object surface includes applying a screen of ink drops to the region to create print dots, calculating the screen using a computer and generating and applying ink drops to the region using a print head having nozzles on a nozzle surface. The steps include a) providing data representing the print image, b) providing or calculating data representing the region, c) providing or calculating path data on paths for the print head or object, d) calculating application locations of ink drops using data from steps b) and c), e) calculating data based on tiling the region using data from step d), f) calibrating tone values using data from step e), g) screening the print image using data from step f), and h) printing the screened image onto the region. A device implementing the method is also provided.

This disclosure describes container(s) having an ultraviolet (UV)-cured matrix and methods to create the same. For example, a glass container according to this disclosure has a bottom and a body extending in a direction away from the bottom along a longitudinal axis. The body has a surface having an UV-cured matrix including UV-curable varnish drops arranged in a plurality of layers and having voids existing therebetween to form a porous matrix structure. One method to form the glass container is to apply a layer of UV-curable varnish to an outer surface of the glass container as a plurality of varnish drops, so as to establish a plurality of voids between the varnish drops, cure the layer of UV-curable varnish, apply one or more additional layers of UV-curable varnish, and cure the additional layer(s) of UV-curable varnish, wherein all of the varnish drops and the voids form the UV-cured matrix.
