A sve bih prevela ovako:
\"... prints with cyan dye analogue tracks will be 12db lower than the digital track and sound will be distorted.\"

\"... na cyan-pigmentnim medijima nivo analognih zapisa biće 12 db niži od nivoa digitalnih zapisa i zvuk će biti izobličen...\"
malo sobodnije, ali mislim da je potpuno OK
