The aluminum-based RC inkjet printing paper with alumina as the pigment of the ink-absorbing coating has become the main product of domestic RC inkjet printing paper because of its simple production process and equipment, strong coating toughness, bending resistance and low cost. However, since aluminum-based RC inkjet printing paper is prone to "bright spots", in the field of high-end inkjet printing, silicon-based inkjet printing paper products occupy a major market share, and the "bright spots" of aluminum-based inkjet printing paper " The ills have affected its application in the field of high-end inkjet printing.
Analysis on the Causes of "Bright Spots" of Aluminum-based RC Glossy Inkjet Printing Paper
The disadvantage of "bright spots" on aluminum-based RC high-gloss inkjet printing paper is that the surface of the ink-absorbing coating is rubbed to produce fine scratches, and the light at the scratch interface is caused by the difference in refractive index between the air inside the scratch and the coating. Refraction and reflection lead to changes in the reflected light on the local surface of the coating, resulting in the disadvantage of "bright spots".
