  Energy spectra of gamma-ray blazars may contain an imprint from the cosmic
infrared background radiation due to gamma-ray absorption (pair-production) by
soft photons constituting the extragalactic background light (EBL). The
signature of this imprint depends on the spectral shape of the EBL. In this
work we correct the observed spectra of Mrk 421 and Mrk 501 for absorption
using different possible realizations of the EBL, consistent with the most
recent detections and limits. We present the intrinsic gamma-ray spectrum of
these sources for the different EBL scenarios. These spectra reveal their true
peak energy and luminosities, which provide important information on the nature
and physical characteristics of the particle acceleration mechanism operating
in these sources.
