When it comes to client communication, you want it to be vivid. From making initial contact, negotiating a tough deal, to advertising abroad there is no room for miscommunication. Clarity of meaning is not enough though. You want creative use of language to convey your message appropriately in the target culture. You want all client communication to evoke an image that will literally jump off a page and have an impact. Your intended meaning must be vivid.
