Abstract: A printing device and method containing a carriage supporting print heads with a plurality of discharging elements to the image-wise forming of image dots of a marking substance on an a print medium, wherein the carriage is moveable in reciprocation in a main scanning direction and is also relatively displaceable with respect to the print medium in the sub scanning direction. Moreover, at least one radiation source is provided for irradiating the image dots of marking substance. The radiation source is designed such that the print medium with the dots formed thereon receives, in a traverse of the radiation source, a radiation dose which increases towards an edge of the dimension in the sub scanning direction of the area irradiated by the radiation source in the traverse.

Abstract: Systems and methods for delivering ink by controlling a pressure of the ink. A vacuum or partial vacuum is maintained at an ink reservoir that supplies ink to one or more print heads. As the temperature of the inks or of the printing system changes, the pressure of the ink experiences a corresponding change. The printing system is equipped with temperature sensors to detect the temperature of the ink, the print heads, or the printing system. The temperature data is processed and an adjustment is made to the partial vacuum maintained on the ink reservoir to accommodate changes in temperature. The temperatures are repeatedly sampled to ensure that the pressure of the partial vacuum is properly maintained for current temperatures.

Abstract: A printing system for drying ink deposited upon a printable medium. The system including at least one print head for directing ink onto the medium as the print head moves over the printable medium. Moving with the print head is at least one halogen lamp that generates electromagnetic radiation having a sufficient wavelength to penetrate the ink. The at least one halogen lamp may irradiate the printable medium and/or the platen, with one or both of the printable medium and the platen aiding with drying the ink deposited upon the printable medium.

Abstract: Systems and methods for selecting a media and a page size. A combination is provided for each media/page size pair in a printing system. A user can select a combination from a list of combinations and the media and page size that correspond to the selected combination are identified and used for a print job of the user. A color profile is selected automatically. The selected media is loaded in an appropriate printer and printed. The combination is an encrypted value that includes a media and a page size. The combination optionally includes an entity identifier. The combinations or identifiers are usually specific to a particular entity and cannot be used by other competing entities.

Abstract: Systems and methods for curing inks with radiation. An apparatus includes a housing that includes a pair of reflectors and/or two separate lamps of different power that direct ultraviolet radiation onto the inks being cured. The pre-cure reflector only reflects a portion of the radiation such that the inks are not fully cured. The pre-cure reflector causes the inks to change or thicken slightly such that they do not move on the media or merge with other inks while still retaining a liquid or wet nature. All colors of ink can then be placed in a single layer before the cure reflector fully cures the UV inks by reflecting sufficient UV radiation onto the single layer of UV ink.
