Blanket memory artifact reduction
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.

a set of second heat sources to heat the external surface of the blanket at a fourth arc of the rotation path, the set of second heat sources to heat the external surface of the blanket following the first transfer of the ink to the blanket from the photoconductor drum at the first arc before the second transfer of the ink from the blanket to the media at the second arc.
13. The system of claim 12 , wherein the set of second heat sources are to heat the external surface of the blanket to about 120° C. to 200° C. before ink transfer from the blanket to the media.
14. The system of claim 10 , wherein the media is to contact the blanket only at the second arc of the blanket path.
15. The system of claim 10 , wherein the media is excluded from the third arc of the blanket path.
16. 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 second ink transfer module, that when executed causes the processor to initiate a second transfer of the ink from the blanket to a media at a second arc of the blanket path; and
