Abstract
A printing system and method form one or more pretreatment compositions on a medium. The one or more pretreatment compositions are selected based upon a parameter of the medium.
Claims17
A printing system comprising:
- a media transport configured to transport a medium;
- a parameter obtaining unit configured to obtain at least one parameter of the medium;
- a selector unit configured to select one or more of a plurality of pretreatment compositions to be formed on the medium based on the least one obtained parameter, wherein the at least one parameter comprises at least one of reflectivity and absorptivity;
- one or more pretreatment applicators configured to form the selected one or more of the plurality of pretreatment compositions on the medium;
- and
- a fluid applicator configured to apply fluid to the one or more pretreatment compositions on the medium to form one or more images.
