Undoubtedly, within the last couple of decades, the progress in non impact printing technologies has grown to an enormous level. In order to keep the development of this non impact printing method to grow even more, technicians, researchers and educators must continue in conducting investigation and provoking new ideas and questions that will lead to new outcomes and expansion of ink jet printing.
In this work, a broader area that comprises deep look into the ink jet ink and substrate performance, their physical properties and optical properties when printed is discussed in great details. Innovative techniques, novel materials and novel recommendations are presented here in order to enhance the progress in the area of ink jet technology in near future.
The output should be evaluated in terms of overall printer capability, not only in terms of a substrate quality (price, grade, optical and physical properties), the type of ink set, and the basic level of color reproduction (density, Lab values). All these should be taken into consideration together with other very important factors, such as the length of time required for colors to stabilize, the image permanence of the printout, and the ink levels in terms of color gamut.
The work includes a comprehensive study of ink and substrate combinations, the interaction between them, and integration of novel techniques, two and three dimensional color gamut projections and gamut volume values, into color output characterization. Using this method it is possible to demonstrate howproperties of a substrate correlate with the final output presentation. The aforementioned approach can be also used as an image permanence evaluation technique, in preference to the change in densities and L*a*b* values of miniature charts. Definitely, the gamut volume can be utilized as a sophisticated device, which enables to control the final color output of the printing job.
