Abstract
In accordance with one embodiment, a printing device includes a sub-assembly for positioning ink on a print media. The printing device also includes a conditioning sub-assembly having a plurality of components, wherein the plurality of components has a first configuration to transfer conditioning material to the print media as the print media is fed through the printing device and a second configuration that does not transfer conditioning material to the print media as the print media is fed through the printing device.
Claims36
An ink jet printing device comprising:
- an ink ejecting sub-assembly for positioning ink on a print media;
- and,
- a conditioning sub-assembly having a plurality of components, wherein the plurality of components has a first configuration to transfer conditioning material to the print media as the print media is fed through the printing device and a second configuration that does not transfer conditioning material to the print media as the print media is fed through the printing device.
A printing device comprising:
- a sub-assembly for positioning ink on a print media;
- and,
- a conditioning sub-assembly having a plurality of components, wherein the plurality of components has a first configuration to transfer conditioning material to the print media as the print media is fed through the printing device and a second configuration that does not transfer conditioning material to the print media as the print media is fed through the printing device.
A printing device comprising:
- means for evaluating print stream data to determine whether a conditioning material should be applied to print media upon which an image representing the print stream data is to be formed;
- and,
- means for applying conditioning material to a print media if said act of evaluating indicates that print quality can be improved with the application of the conditioning material, and not applying conditioning material to a print media if said evaluating indicates that print quality will not be improved with the application of the conditioning material.
A method comprising:
- positioning a first roller a first distance from at least a second roller when a print media is positioned between the first roller and the second roller effective to transfer conditioning material from the second roller to the print media;
- and,
- positioning the first roller a second distance from the second roller when print media is not positioned between the first roller and the second roller, wherein the second distance is greater than the first distance and effective to prevent conditioning material from being transferred from the second roller to the first roller.
A method comprising:
- positioning a first roller a first distance from at least a second roller when a print media is positioned between the first roller and the second roller effective to transfer conditioning material from the second roller to the print media;
- and,
- moving the first roller away from the second roller effective to avoid transferring conditioning material to another print media.
A method comprising:
- feeding print media into a print unit of a printing device;
- and,
- moving a pinch roller between a first position and a second position based, at least in part, on the presence of print media between the pinch roller and a transfer roller, wherein in the first position the pinch roller causes a print media positioned between the pinch roller and the transfer roller to receive a conditioning material from the transfer roller and being in the second position the pinch roller does not cause conditioning material to be transferred to the print media.
A method comprising:
- positioning a top roller proximate to a bottom roller when a print media is positioned between the top roller and the bottom roller so that conditioning material is transferred from the bottom roller to the print media;
- and,
- positioning the top roller further from the bottom roller when print media is not positioned between the top roller and the bottom roller to prevent conditioning material from being transferred from the bottom roller to the top roller.
A method comprising:
- applying a hydrophilic material to substantially all of a sheet of print media to pre-expand the print media;
- and,
- transferring ink onto the print media to form a desired image.
A method comprising:
- evaluating print stream data to determine whether a conditioning material should be applied to print media upon which an image representing the print stream data is to be formed;
- applying conditioning material to a print media if said act of evaluating indicates that print quality can be improved with the application of the conditioning material;
- and,
- not applying conditioning material to a print media if said evaluating indicates that print quality will not be improved with the application of the conditioning material.
1 more element
One or more computer-readable media having computer-readable instructions thereto which, when executed by a printing device, cause the printing device to:
- evaluate print stream data to determine whether a conditioning material should be applied to print upon which an image representing the print stream data is to be formed:
- apply conditioning material to print media if an evaluation indicates that print quality can be improved with the application of the conditioning material;
- and
- not apply conditioning material to a print media if the evaluation indicates that print quality will be improved with the application of the conditioning material.
