Paper and ink characteristics effect on print density were investigated.  For this purpose three types of papers and four types of printing inks at 2 viscosities levels (25-30, 50-55) were used. Then characteristics of paper & ink were measured. Inks on sampled papers Printed and then printing density was measured. Statistical analysis was conducted based on a complete randomized design in factorial experimental model and means were analyzed and grouped by Duncan multiple range test (DMRT) using SPSS software. Result indicated that Solid content, pH and particles diameter of inks have significant effect on print density. While roughness and water absorption of papers do not have on significantly influences print density. There was not any significant different between two viscosity level and print density
