CMYK conversion is based on various factors including ink sets, dot gain, paper and paper stock.
Since we cannot predict which setting are needed by your printer, nor can we do a sample print run to fine tune the CMYK conversion, it is best to receive an RGB image from us and have the printer do their own conversions. The default settings for CMYK conversion which we can provide may not produce the best results for your project. Transparencies or Prints are also available for most images.
