Blazars are a type of radio-loud active galactic nuclei (AGN) whose (relativistic) jets are pointing very close to the line of sight of the observer. In previous studies (Mimica & Aloy 2010, 2012) we have performed a limited parameter study in the context of the internal shocks (IS) model in blazar jets. The focus of the previous work was studying the signature of the magnetization of colliding shells on the light curves and spectra. In the present work we focus on a limited number of different shell magnetization levels, but extend our coverage of the parameter space to include varying parameters such as the jet viewing angle, shell bulk Lorentz factor, and their relative Lorentz factor. The data obtained in these simulations was analyzed in order to find and so categorize the specific effects that different values of each parameter induce on the spectra, and these synthetic observations compared with those from the 2LAC catalog of blazars observed by Fermi.
