We develop a rigorous quantum-mechanical treatment of color transparency effects in diffractive photoproduction of {ital {bar c}c} pairs on nuclei. The evolution of the {ital {bar c}c} wave function during propagation through a nucleus is more a considerable distortion of its form than a trivial attenuation. One of the manifestations of the quantum effects is a nuclear antishadowing of the {psi}{prime} yield, i.e., transparency above one. However, considerable nuclear shadowing is predicted for the photoproduction of {ital J}/{psi}, which has a much smaller absorption cross section than {psi}{prime}.
