    摘要: Individually controllable ultraviolet (UV) light-emitting diodes (LEDs) are used to cure ink and generate different effects. The UV LEDs only expose specified areas to generate the different effect and can create multiple effects on the same substrate by exposing different areas to varying amounts of time or by performing a curing stage and post-dosage curing stages. The different effects include generating a glossy surface, a matte surface, and sharper images.

    摘要: White-balance is improved when printing on colored media, while minimizing the time and use of costly materials required by present approaches. In an embodiment, the typical solid white fill or background layer is altered by including in the white layer one or more of the other colors already available in the printer to shade this layer. Thus, a small amount of cyan, for example, helps balance a pink-ish (red) media; yellow is used for blue media; and magenta is used for green media; as well as combinations thereof. A combination of transparent process inks and opaque white helps to maintain brightness (luminosity).

    摘要: Image processing of printed patterns of arrays of dots generated by an array of inkjet heads uses a vision system, including an HD color camera that can be a fixed focus or include autofocus and zoom capabilities. Pattern recognition techniques are used to analyze as many patterns as necessary to perform multiple alignment functions, such as dot size, shape, and integrity; unidirectional, bidirectional, and step alignments; physical position and straightness of jet packs; flatness of platen or media belt; mapping imperfections in rods and rails of guiding systems; and checking jet alignments from a reference jet to all other jet packs. From such image analysis, correction values are generated that are used to effect manual or automatic adjustment of the inkjet heads physical position, voltage, temperature, and firing pulse timing and/or duration; and to position the printed dots fired from the nozzles in the inkjet heads in the appropriate position.

    摘要: Disclosed herein is a technique that enables a carriage printer to reduce precision in a media conveyor by improving mobility of the carriage. The carriage includes a mobile jetplate that adjusts the position of the printheads within the carriage. The mobile jetplate includes multiple motors that enable shifts in an axis matching the axis of the media. Operating the motors of the jetplate at different locations or at different intensities causes the jetplate to skew and achieve mobility of multiple axes. A set of sensors monitor media skew and shifts of the mobile jetplate are able to compensate for that skew. An additional set of motors shift the carriage to compensate for deformation of the beam that the carriage shuttles along.

    摘要: Improved output quality of a printer used in UV curable ink jet printing is achieved by minimizing or eliminating a print artifact referred to as gloss banding or tire tracking. A same or a similar number of nozzles as used in conventional printers is used to achieve a desired throughput, but the nozzles are arranged so that any given square inch of substrate to which ink is being applied receives a lower amount of ink. A longer effective print head is provided by arranging the print heads into a longer array, where the print heads are butted substantially end-to-end. As a result, the net throughput of the printer is the same as that of a conventional printer because the printer uses the same number of print heads, but the amount of ink that is applied to any given square inch is less on a pass.
