The invention relates to a device for digitally printing a profiled strip (6), comprising a plurality of digital print heads (3) which can be oriented relative to a conveyor (1) conveying the profiled strip (6) past the print heads (3) in the longitudinal direction. In order to create advantageous guiding conditions, it is proposed that the conveyor (1) has a plurality of conveying members (2) guided in a circulating path, that the circulating path forms a conveying section with a straight guiding section (5) for the conveying members (2), and that the conveying members (2) are provided with a receptacle for the profiled strip (6) which holds the profiled strip (6) in a manner fixed against displacement during the movement of the members along the straight guiding section (5).

In this print method, assuming that the number of stacking of ink layers in a thickest portion in a thickly-piled portion is N, in a histogram preparation step ST2, a histogram of luminance values of grayscale image data prepared in an image data preparation step ST1 is prepared, and in luminance value range setting steps ST3 to ST10, a luminance value of predetermined gradations of the histogram is divided into N and N luminance value ranges are set. In the luminance value range setting steps ST3 to ST10, a division position of the luminance value of the predetermined gradations is adjusted while the histogram displayed on a predetermined display is checked.

Systems and apparatuses for applying coating to nails are disclosed. In one aspect, embodiments of the present disclosure include a method, which may be implemented on a system, to performing image processing on an image of the nail to locate a boundary of the nail. The method can further include determining a path along which to move the nail relative to an applicator, the applicator being used to coat the nail. In a further embodiment, using the located boundary of the nail, a dispensing procedure for the applicator to follow to coat the nail is determined.

The invention relates to a method for printing objects, in particular containers, wherein the containers are transported along a specified transport path, and the outer surface of the containers is printed at least temporarily by means of at least one printing unit, wherein a controller controls the printing of the containers by means of the at least one printing unit on the basis of at least one printing parameter. According to the invention, at least one object to be printed is printed with at least one test marking in order to ascertain the printing parameter, and the object provided with the test marking is then inspected by means of at least one inspection device, wherein the printing parameter is derived from the result of the inspection.

In a method for the production and/or treatment of a three-dimensional object with a printing material which is dispensed at a target position in the form of discrete three-dimensional printing material elements, a metering device is moved to at least one reservoir in which a supply of printing material is kept and, by means of the metering device, printing material is picked up from that at least one reservoir. The metering device is transported to a target position defined in all three spatial dimensions and, at that target position, a metered quantity of printing material is applied to a substrate or to a three-dimensional object arranged thereon or being constructed thereon, in order to create a printing material element. The creation of a printing material element is repeated until the three-dimensional object has been fully constructed and/or treated. The use of a metering device for picking up, transporting and applying printing material makes it possible for virtually any desired printing materials to be processed and, accordingly, for objects to be produced and/or treated with virtually any desired printing materials.

In a method and a device for inkjet printing on containers, at least a first and a second subprint complementing each other in the printing direction so as to form a print image are joined. The first subprint is printed starting from a connection area or up to a connection area. Subsequently, the second subprint is printed with a feed towards the connection area such that the first and second subprints interleavingly overlap in the connection area. This allows a joining of subprints with unobtrusive transitions even in the case of dimensional tolerances and complicated cross-sections of the respective container.

The present invention provides a glass slide printer, which comprises: a conveying device, an inkjet device, and a curing device; wherein the conveying device has a conveying path, and causes the glass slide to be printed to move along the conveying path; the inkjet device is provided above the conveying path, and is configured to perform inkjet printing on the marked area of the glass slide on the conveying path; the curing device is provided above the conveying path, and the curing device is located downstream of the inkjet device; the curing device is capable of curing the printing ink droplets ejected onto the glass slide to form characters or two-dimensional codes by heating or ejecting curing liquid.

Described herein are systems, devices, and methods to manufacture a feature onto the rim of an ophthalmic lens. In one embodiment, there are multiple lens rim features, and they are substantially restricted to the periphery of the lens. In alternative embodiments, the lens rim features are substantially restricted to either the top half or the bottom half of the periphery. In some embodiments, the features are added to a lens that has been finished for vision correction, whereas in other embodiments the features are added to a semi-finished lens. In one embodiment, there is a device for printing lens rim features onto an ophthalmic lens, and in another embodiment there is a system for printing such lens rim features. One embodiment is a method for printing a lens rim feature onto a lens, including the use of a device with a print-head and one or two grasping devices.

A topical high resolution image of edible ink and having a resolution of at least 100 dots per inch is applied to a top major surface of a length of food (14) in the form of a thin fruit based paste or confection slurry by a digital imaging printer (130). The length of food (14) is at a temperature of at least about 75° C. at the time of application. During application, the food (14) is supported upon a moveable platform (136) mounted by parallelogram links (138) and which is moved parallel to the digital imaging printer (130) according to a condition of the top major surface upon which the topical high resolution image is applied and detected by detecting provisions (144).

A printing system includes a first member and a second member. The second member is positioned parallel to the first member. The system further includes a first extensible member and a second extensible member. The system further includes a first gripper and a second gripper. One end of the first extensible member is mounted to the first member and the other end of the first extensible member is mounted to the first gripper. One end of the second extensible member is mounted to the second member and the other end is mounted to the second gripper. A controller operates a first actuator operatively connected to the first and second extensible members.
