The work aims to prepare a light-emitting diode (LED) curable orange-peel ink to generate an orange-peel effect on the surface of paper packaging. Gas-phase SiO2 was added to the basic formula of the LED curable ink, to reduce the ink absorbency of the paper on the one hand, and regulate the fluidity of the ink on the other hand. After screen printing, the surface ink layer was prone to flow and form patterns under the action of the orange-peel agent, polydimethylsiloxane, and the patterns did not level out before curing, solving the problem of poor orange-peel effect on the paper surface. The rheological properties such as rheology and viscoelasticity of the orange-peel ink were characterized with an HR-10-TA rheometer. The ink formula was as follows:photoinitiator 819 was 1%, thermoplastic polyolefin elastomer (TPO) was 4%, active amine 008 was 10%, active monomer ACMO was 15%, polyurethane acrylate prepolymer was 54.5%, color paste was 10%; polydimethylsiloxane was 1.5%, gas-phase SiO2 was 3.5%, and wax powder was 0.5%. Rheological tests showed that the ink had shear-thinning characteristics, with a flow point of modulus G'=G 2 to regulate the fluidity of the ink and using polydimethylsiloxane as the orange peel agent, the orange peel effect on the paper surface is visually good after screen printing and LED curing.
