We investigate joint remote state preparation in the presence of noises caused by surrounding environments. We consider all possible noisy scenarios experienced by some or all the qubits of the shared quantum channel. The results cannot be described in a general manner so case-by-case analyses must be carried out. In particular, we show that quality of the prepared state is better when the qubits are subjected to optimal combinations of different types of noises than when they undergo the same noise type. Furthermore, we indicate that under certain scenarios less entanglement or more noise may make the preparation process more efficient.
