this research, a lithography ink formulation has been prepared base on the Maleic and Alkyd resin. Then, the rheological parameters such as viscosity vs. shear rate, thixotropy cycle, storage and loss modules were studied. It was observed that Z0 values augmented severely by increasing the pigments concentration and reducing the particle size distribution. On the other hand, Z[ values did not change noticeably except for the sample that consisted of 10% pigment. Besides, the differences between dynamic parameters in low frequencies were obvious
