Abstract
In one example, a development cycle of a binary ink developer, BID, is timed. Timing may be based on the length of a substrate in which the image is to be printed or the size of the image or the area to be printed with the ink associated to the BID.
Claims12
A method comprising:
- timing a development cycle of a binary ink developer, BID, on the basis of the length of a substrate in which the image is to be printed or the size of the image or the area to be printed with the ink associated to the BID;
- wherein the timing is repeated for different inks, and the method comprises determining different upper or lower margins for different inks.
A system to control ink development from at least one developer roller to a photoreceptor, the system being to perform at least one of:
- starting the development of ink in correspondence with an upper margin of a page, image or print area;
- and
- concluding the development of ink in correspondence with a lower margin of a page, image or print area, wherein the at least one developer roller comprises at least a developer roller to be engaged to the photoreceptor and an electrode to develop ink.
A non-transitory memory device comprising executable instructions which, when executed by a processor, causes the processor to:
- control a first developer roller to start or conclude ink development operations for a first ink based on dimensional parameters of an image or print area to be printed with the first ink;
- and
- control a second developer roller to start or conclude ink development operations for a second ink based on based on dimensional parameters of an image or print area to be printed with the second ink.
