The process \(e^+e^- \to \omega\pi^0 \to \pi^+\pi^-\pi^0\pi^0\) is studied in the center-of-mass energy region \(1.05-2.00\) GeV using data with an integral luminosity of about 35 pb\(^{-1}\) collected with the SND detector at the VEPP-2000 \(e^+e^-\) collider. In the energy range under study, the value of the measured Born cross section varies from 0.7 to 18 nb. The statistical uncertainty of the cross section is \(2-23\)%, while the systematic uncertainty is in the range of \(3.0-14.2\)%. The results are consistent with previous measurements but have better accuracy.
