I designed a 5.5" x 4 3/16" inch flyer in Illustrator. I set the bleed to 0.125 inch. I finished the flyer and saved it using the PDF/X-1a:2001 preset, left the rest as default. Then delivered it to the client. But he is asking me to create a one-eighth-inch bleed and crop marks. How come? Because I already set the bleed as I said before to 0.125 inch. I also printed a sample of the flyer to check that, and it is printed correctly.
I am really confused, should I save it as a press quality PDF and mark the printer's marks and bleeds or leave it the same?
