Measurements of exclusive incoherent electroproduction of {rho}{sup 0} (770) meson from {sup 2}D, {sup 12}C, and {sup 63}Cu targets up to Q{sup 2} = 4 GeV{sup 2} are proposed using the CLAS detector. The objective of these measurements is to determine the Q{sup 2} dependence of the nuclear transparency ratio for the two nuclear targets: {sup 12}C and {sup 63}Cu at fixed coherence length of quark-antiquark fluctuations of the virtual photon. A sizeable rise of the nuclear transparency is predicted and can be measured in this experiment. A relatively large increase of the nuclear transparency can be considered as a signature of the onset of color transparency.
