Abstract
Embodiments of the present invention provide a method for use in a printing device, comprising outputting a test chart comprising a plurality of printed regions at respective ink densities, receiving an indication of a selected ink density, and determining one or more resources of the printing device according to the selected ink density to control one or more ink limits and a colour separation of the printing device.
Claims19
A method comprising:
- determining a desired region, of a test chart printed on a medium with pretreatment fluid, at which sufficient ink drying has occurred;
- and
- when outputting ink to form an image by a printing device, using an ink density corresponding to the desired region.
A non-transitory computer-readable data storage medium storing a computer program executable by a processor to perform a method comprising:
- determining a selected test chart of a plurality of test charts printed on a medium with pretreatment fluid at respective pretreatment levels, the selected test chart having an optimal pretreatment level;
- determining a desired region at which sufficient ink drying has occurred on the selected test chart;
- and
- when causing a printing device to form an image by outputting ink, causing the printing device to use the optimal pretreatment level of the selected test chart and an ink density corresponding to the desired region on the selected test chart.
A printing system comprising:
- a printing mechanism to output pretreatment fluid and ink on a medium;
- a controller implemented at least by hardware including a processor and that is to:
- cause the printing mechanism to output a pretreatment fluid on the media;
- cause the printing mechanism to output a test chart on the medium on which the pretreatment fluid has been output, the test chart comprising a plurality of regions at respective ink densities;
- determine a desired region at which sufficient ink drying has occurred;
- and
- when causing the printing mechanism to form an image by outputting ink, cause the printing mechanism to use an ink density corresponding to the desired region.
