Techniques described herein automatically discover the IP address of a first network device such as but not limited to a multifunction printer. Such techniques use a unique identifier of the first network device, such as for example a multifunction printer serial number. Such unique number is used in the configuration of a second network device, such as for example a Digital Front End/External Print Controller that may need the IP address of the first network device. The unique number may be entered once into the second network device or may be received from the first network device through a data interface by the second network device. Techniques then may use any available broadcast technology such as but not limited to Simple Network Management Protocol (SNMP) to determine from available network devices which network device therefrom has the same unique number, thereby obtaining the IP address of the first network device.

A radiation-curable ink composition for application to glass, ceramic, or metal by an inkjet printer. The ink composition can be applied to a glass, ceramic, or metal substrate to decorate, protect, etc. the substrate. In some embodiments, the ink composition includes a glass frits component, a chromophore component, and a UV-curable component. The glass frits component facilitates the fusing of the ink component with a glass, ceramic, or metal substrate to which the ink composition is applied. The chromophore component is the primary colorant of the ink composition. The UV-curable component facilitates activation of polymerization upon exposure to ultra-violet (UV) radiation, which causes the ink composition to cure and fix/pin to the underlying substrate. After the ink composition is applied to a substrate and cured by exposure to UV radiation, the substrate is heated to a temperature that causes the ink composition to fuse with the substrate.

Color prediction for color printing is performed in response to loading media into a printer and initiation of a calibration sequence, using one or more sensors to measure physical properties of the media. Based at least upon the measured physical properties, an optimal preset is identified in a database and the optimal preset is loaded into the printer as a starting calibration. A difference from values in the optimal preset loaded into the printer and those of the measured physical properties is determined and the printer prints a chart. The sensors measure the chart and the measurements of the chart are used to fine tune the optimal preset. The fine tuned preset is then saved as a new media profile.

Compensation algorithms are applied to hide failed nozzles or, at least, reduce the objectionable effect of such nozzles in a printed image. Once a failed nozzle or under-performing nozzle is detected in a single-pass printing system, it is shut-off and the image data that was intended to be printed by this nozzle is redistributed to its neighboring nozzles. Embodiments of the invention use of a 1-D look-up table and stochastically distribute the duty cycle to each neighboring nozzle. In this way, failed nozzles are effectively hidden in the final print.

Apparatuses and embodiments related to compensated laser cutting of labels. A computer system receives an image of a label, and rasterizes the image. The computer system determines how much of each type of printer ink of a label printer to deposit at each pixel location of the image. The computer system determines which pixels intersect a cut line, and determines the characteristics of the ink of the pixels, such as the quantity or thickness of the ink at the pixel locations. The computer system determines laser data including power, cut speed, and/or frequency of a laser that is tuned to accurately cut through the ink that forms the image, the material(s) of the label, and the adhesive that removably adheres the label to base material(s), but to not excessively damage the base material(s). A laser cutting system uses the laser data to control a laser.

Virtual ink channels are created with colored media and white ink to afford multichannel ICC profile creation by using ICC profiling software. The available color gamut is enhanced for an device that defines a color space with a color profiler, e.g. an ICC profiler. Thus, an available color gamut for an input or output device is enhanced or extended by creating virtual ink channels for use with profiling software. This allows the use of media types and/or inks that are otherwise not supported by the profiling software.

Enhanced inks, and associated systems and processes are disclosed, wherein one or more enhanced inkjet layers are established in a work piece, i.e. a substrate. One or more of the inks comprise a selective photo absorber that allows UV curing, while absorbing incident UV light after production. In some embodiments, the selective photo absorber can be configured to absorb light at wavelengths less than 380 nm, while a photoinitiator in the ink can be activated by light having an average wavelength that is equal to or greater than 380 nm. Incident UVA and UVB light is readily absorbed by the cured enhanced ink layer, thus minimizing deleterious effects such as any of yellowing, loss of gloss, or cracking. The selective photo absorber can be used in one or more layers, and can be used on an outer protective inkjet layer.
