Spectral-based printer modeling and characterization

Spectral-based printer modeling and characterization

Spectral characterization involves building a model that relates the device dependent representation to the reflectance function of the printed color, usually represented with a high number of reflectance samples at different wavelengths. Look-up table-based approaches, conventionally employed for colorimetric device characterization cannot be easily scaled to multispectral representations, but...

An innovative method for spectral-based printer characterization

The paper presents an innovative approach to the spectral-based characterization of ink-jet color printers. Our objective was to design a color separation procedure based on a spectral model of the printer, managed here as an RGB device. The printer was a four-ink device, and we assumed that the driver always replaced the black completely when converting from RGB to CMYK amounts of ink. The col...

Using genetic algorithms for spectral-based printer characterization

In recent years, many methods have been proposed for the spectral-based characterization of inkjet printers. To our knowledge, the majority of these are based on a physical description of the printing process, employing different strategies to deal with mechanical dot gain and the physical interaction among inks. But our experience tells us that as printing is a physical process involving a lar...

Colorimetric characterization of a 3D printer with a spectral model

Abstract As 3D printing becomes an increasingly popular technology, knowledge of the processes employed by a printer becomes more important. In this paper, one particular printer, the Zcorp Spectrum Z510, is studied in terms of its color production. Two approaches to a spectral model are evaluated in terms of their ability to predict output colors of the printer based on input RGB values. The m...
