Influence of Developing Sericite to Replace Traditional Materials on Color Inkjet Printability

This research object mainly developed the raw materials—sericite,which replaced the input silica materials due to its characteristic properties.There are five coatings formulations were prepared,input silica was replaced by domestic sericite from 0% to 20% proportion,then uses these coatings and base paper with coater to make a novel digital imaging output paper.Lastly,color data evaluations and analysis on paper from inkjet printer are finished with color target chart through spectrophotometer.The outcome of this research found out that overall color gamut decreased,the brightness of shade area increased from 5% to 10% sericite proportion.But it initiated to turn back suddenly in 15% sericite proportion,overall brightness continued to increase,color gamut domain broadened out simultaneously.In 20% sericite proportion,the color gamut domain broadened out clearly more than 15%,and overall brightness was the widest than any proportions.The brightness of shade area increased in proportion to the sericite,which replaced silica.Color gamut domain turned back from 10% to 15% sericite proportion.
