Abstract
In one example of the disclosure, a first transfer of ink is made from a photoconductor to a blanket in contact with the photoconductor. The blanket is to cycle along a path. The first transfer occurs at a first arc of the blanket path. A second transfer of the ink is made from the blanket to a media in contact with the blanket. The second transfer occurs at a second arc of the blanket path. A heat source located adjacent to a third arc of the blanket path is utilized to heat an external surface of the blanket. The heating is to occur following the second transfer of the ink.
Claims17
A method for reduction of memory artifacts in a blanket during printing, comprising:
- making a first transfer of ink from a photoconductor to a blanket in contact with the photoconductor, the blanket to cycle along a path, and the first transfer occurring at a first arc of the blanket path;
- making a second transfer of the ink from the blanket to a media in contact with the blanket, the second transfer occurring at a second arc of the blanket path;
- and
- utilizing a heat source located adjacent to a third arc of the blanket path to heat an external surface of the blanket, the heating to occur following the second transfer of the ink.
A system for heating a blanket to reduce memory artifacts in a blanket during printing, comprising:
- a blanket to be situated upon a rotatable blanket drum,
- wherein the blanket is to be in contact with a rotating photoconductor drum and is for receiving a first transfer of ink from the photoconductor drum at a first arc of a rotation path for the blanket drum;
- wherein the blanket is to be in contact with a media situated upon a rotating media drum, and is for making a second transfer of the ink from the blanket to the media at a second arc of the blanket drum rotation path;
- and
- a heat source to be located adjacent to a third arc of the rotation path, and to heat an external surface of the blanket, the heating to occur following the second transfer of the ink at the second arc and before the blanket drum rotates to the first arc for a new transfer of ink from the photoconductor drum.
A memory resource storing instructions that when executed are to cause a processing resource to enable reduction of memory artifacts in a blanket during printing, comprising:
- a first ink transfer module, that when executed causes the processor to initiate a first transfer of ink from a photoconductor to a cycling blanket in contact with the photoconductor, the first transfer occurring at a first arc of a path for the blanket;
- a first heating module, that when executed causes the processor to initiate a set of heating sources located at a fourth arc of the blanket path to heat the external surface of the blanket to about 120° C. to 200° C., with the heating to occur following the first transfer of the ink from the photoconductor to the blanket, and before a second transfer of the ink from the blanket to the media at a second arc of the blanket path;
- a second ink transfer module, that when executed causes the processor to initiate the second transfer of the ink from the blanket to the media;
- and
- a second heating module, that when executed causes the processor to initiate a laser emitter located adjacent to a third arc of the blanket path to heat an external surface of the blanket, the heating to occur following the second transfer of the ink and before the blanket returns to the first arc for a new transfer of ink from the photoconductor, and to heat the external surface of the blanket to about 90° C. to 160° C.
