The Preparation of Color Ink-Jet Paper Coating and the Investigation of its Printing Quality

In order to know the coating effect and application of color ink-jet paper, the coating formula and printing quality of ink-jet paper were deeply studied. First of all, the coating liquid was prepared by dispersing and mixing the nanometer pigment, the adhesive and the other additives. Then the properties of ink-jet paper were tested and their surface profiles were characterized and evaluated with scanning electron microscope. Finally, the coating paper samples and the base papers were all printed with color ink-jet printer and measured with a spectrodensitometer. The study result showed that it can gain well coating and printing quality when the ratio of SiO₂ and TiO₂ is 3:1 and the content of PVA adhesive is 50%, especially paper whiteness is obviously higher than that before the coating.
