Backdrop Printing

How do I print a backdrop that I created in Illustrator. The whole file is vectorbesides for one part which is an image.
I created it as a quarter size of the actual print size. Does anyone how to send to print so that the image will be print clearly?

Can anyone help me out with this?

Why don’t you ask the printer how to send the files? and how you should set up?

The client is taking care of the printing and its in China- they don’t really communicate with them, they just send it in as is.
