Abstract
An apparatus to calibrate a printer. The apparatus comprises a controller to: control deposition of white printing material on media, the white printing material having an opacity of at least 55%; control deposition of non-white printing material on the white printing material; receive data for at least one sensed characteristic of the non-white printing material; and calibrate the printer using the received data for the at least one sensed characteristic of the non-white printing material.
Claims20
A method to calibrate a printer, the method comprising:
- controlling printing of at least one layer of white ink on a substrate, the at least one layer of white ink having an opacity of at least 55%;
- controlling printing of a layer of non-white ink on the at least one layer of white ink;
- receiving data for at least one sensed variable of the non-white ink;
- and
- calibrating the printer using the received data for the at least one sensed variable of the non-white ink.
An apparatus to calibrate a printer, the apparatus comprising:

- receive data for at least one sensed characteristic of the non-white printing material;
- and
- calibrate the printer using the received data for the at least one sensed characteristic of the non-white printing material.
A non-transitory computer-readable storage medium encoded with instructions that, when performed by a processor, cause performance of:
- control printing of at least one layer of white ink on a substrate, the at least one layer of white ink having an opacity of at least 55%;
- control printing of a layer of non-white ink on the at least one layer of white ink;
- receive data for at least one sensed variable of the non-white ink;
- and
- calibrate the printer using the received data for the at least one sensed variable of the non-white ink.
