Abstract: The print quality in digital printer like Epson Stylus Pro 7900 is influenced by the various printing parameters and among these dot shape, screen resolution and paper are considered to be the major. The study conducted here was to evaluate the print quality in terms of the maximum number of color that it can reproduce on two different printing substrates at different dot shapes and resolutions by maintaining other printing parameters constant. Linearization and profiling of the Epson stylus Pro 7900 printer for all these combinations were completed using IT8.7-3 CMYK standard test target using Harlequin RIP V8.3 software. Then the color gamut volumes are analyzed using Taguchi’s Design of experiments in Mini Tab software. This is done to evaluate the significant parameter that has a major influence on the color gamut. From the result obtained in the project it was concluded that change in the dot shapes and resolutions have less influence on the color gamut than the substrate’s surface property. The glossy effect of the Epson proofing commercial 187 GSM paper has shown a significant change in the color gamut in comparison with the other paper properties and printing attributes. There are different paper substrates available which are mainly made for use in ink jet printer and since these digital devices are widely used for proofing and by photographers, it is better to take similar type of study to know the print quality on different paper substrates and making a profile for each paper is a must for achieving a consistent print in more economic way
