Abstract
White-balance is improved when printing on colored media, while minimizing the time and use of costly materials required by present approaches. In an embodiment, the typical solid white fill or background layer is altered by including in the white layer one or more of the other colors already available in the printer to shade this layer. Thus, a small amount of cyan, for example, helps balance a pink-ish (red) media; yellow is used for blue media; and magenta is used for green media; as well as combinations thereof. A combination of transparent process inks and opaque white helps to maintain brightness (luminosity).
Claims20
A method comprising:
- receiving, from a camera, data that is representative of an image of the substrate;
- identifying a profile that matches a particular media type and a particular color of the substrate that are determined via analysis of the data;
- retrieving, from the profile, a first offset color value for a first offset color;
- printing on the substrate a first layer of ink that includes white ink;
- wherein the printed first layer of ink reduces visibility of the particular color of the substrate;
- and
- printing a second layer of ink on top of the printed first layer of ink.
An electronic device comprising:
- a network interface for communicating with a sensor over a communication channel;
- a processor;
- and
- a memory having instructions stored thereon that, when executed by the processor, cause the processor to:
- receive, from the sensor, data from which a characteristic of a substrate is derivable;
- identify, based on the data, a profile that matches a particular media type and a particular color of the substrate;
- retrieve, from the profile, a first offset color value for a first offset color;
- and
- transmit directions to print on the substrate a first layer of ink that includes white ink;
- wherein the printed first layer of ink reduces visibility of the particular color of the substrate.
A method comprising:
- receiving, from a camera, an image of a substrate;
- identifying a profile that matches a particular media type and/or particular color of the substrate determined via analysis of the image;
- retrieving, from the profile, a first offset color value for a first offset color;
- printing the first offset color on the substrate to create a first layer of ink;
- and
- printing a second layer of ink on top of the first layer of ink.
