dc.description.abstract	We show the role played by QCD evolution and skewedness effects in the DVCS cross section at large Q2 within the color dipole description of the process at photon level. The dipole cross section is given by the saturation model, which can be improved by DGLAP evolution at high photon virtualities. We investigate both possibilities as well as the off-forward effect through a simple phenomenological parameterization. The results are compared to the recent ZEUS DVCS data.	en
