An approach is provided for controlling ultraviolet-curable gel ink spread of a printed image. The approach involves causing, at least in part, one or more inks to be applied to a first substrate image area by one or more inkjets in a printing zone of a printer, the one or more inkjets being configured to form one or more first ink spots on the first substrate image area. The approach also involves determining a temperature of at least the first substrate image area in the printing zone. The approach further involves determining a first spot size of at least one of the one or more first ink spots. The approach additionally involves causing, at least in part, a temperature of at least a second substrate image area in the printing zone to be based, at least in part, on the determined first spot size.

Method and apparatus for controlling ultraviolet-curable gel ink spread of a printed image

Methods of forming images on substrates in printing and apparatuses for forming images on substrates in printing are provided. An exemplary embodiment of the methods of forming images on substrates in printing includes applying ink onto a surface of a substrate; irradiating the ink on the surface of the substrate with first radiation to partially-cure the ink; applying pressure to the substrate and partially-cured ink at a nip with a first surface of a first member and a second surface of a second member to level the ink on the surface of the substrate; and irradiating the as-leveled ink on the surface of the substrate with second radiation to substantially fully cure the ink.

Methods of forming images on substrates with ink partial-curing and contact leveling and apparatuses useful in forming images on substrates

Apparatuses and methods for forming images on substrates in printing are provided and may include a first marking station for applying a first ink having a first color to a surface of a substrate, a first partial-curing station downstream from the first marking station, a second marking station downstream from the first partial-curing station for applying a second ink having a second color to the surface of the substrate, a second partial-curing station downstream from the second marking station, a leveling device for applying pressure to the substrate and the partially-cured first ink and second ink to level the first ink and second ink on the surface of the substrate, and a post-leveling curing device for irradiating the as-leveled first ink and second ink on the surface of the substrate to substantially-fully cure the first ink and the second ink.

Methods of adjusting gloss of images locally on substrates using ink partial-curing and contact leveling and apparatuses useful in forming images on  substrates

Systems and methods of measuring an amount of show-through in a printed document are disclosed. The systems and methods include an imaging device that scans a back side of the printed document and scans a front side of the printed document with a blank document disposed thereon. The imaging device produces bitmaps related to the scans and calculates bit depths associated with the bitmaps. A difference array is calculated based on the differences between the bitmaps of the back side and front side scans, and the average value and standard deviation of the difference array is calculated. The amount of show-through of the document is measured based on a formula with the calculated average and standard deviation.

Apparatuses and methods for forming images on substrates in printing are provided. An exemplary embodiment of the apparatuses includes a first marking station for applying a first ink having a first color to a substrate; a first partial-curing station downstream from the first marking station including a first radiant energy source for irradiating the first ink on the substrate with first radiation to partially-cure the first ink; a second marking station downstream from the first partial-curing station for applying a second ink having a second color to the substrate; a second partial-curing station downstream from the second marking station including a second radiant energy source for irradiating the first ink and the second ink on the substrate with second radiation to further partially-cure the first ink and to partially-cure the second ink; a leveling device formed by a first member and a second member, the first member and second member being configured to apply pressure to the partially-cured first ink and second ink when the substrate is received at a nip to level the first ink and second ink on the surface of the substrate; and a post-leveling curing device for irradiating the as-leveled first ink and second ink on the surface of the substrate to substantially-fully cure the first ink and the second ink.

An ink jet printhead scrubbing and priming method and apparatus are provided. The apparatus of the method includes a capping member for capping a nozzle face of an ink jet printhead. The capping member has a bottom wall and side walls defining a capping recess and a priming path into the capping recess. A nozzle face of an ink jet printhead being capped, the bottom wall and side walls of the capping member together define an enclosed gap within the capping recess that contains air. The apparatus of the method then includes pressure applying devices for alternatingly applying positive and negative pressure within the enclosed gap and to nozzles in the nozzle face of the ink jet printhead being capped. The positive and negative pressures effectively agitate and scrub the nozzles in the nozzle face of the ink jet printhead being capped, thereby facilitating easy and effective subsequent priming of the nozzles in the nozzle face of the ink jet printhead being capped.
