I work together with a printing company. We managed to send the correct print ready file directly to our printing company. Only the print ready file (pdf) is being send. But my printing company also is asking for a preview how the end product will look. So on which place the print needs to be printed on the product. How can I make sure that my printing company receives next to the print ready file an image of the final product that my printing can use to determine the place the print ready file needs to be printed.
