As the title states, when I save a vector file I created in Illustrator as a PDF, the vector is not preserved.
My client has an .ai file for me to insert an pattern image in, then it has to be exported as PDF to go to the printers.
I have a .jpeg image that I created a pattern swatch for, created a seamless pattern the size of my client's artboard, then save as PDF. Only the vector elements of the original file is preserved, the pattern included isn't. But in the Illustrator system, the pattern is vectorized and can be zoomed in and the lines are still crisp. On the PDF, it is not.
I included a screenshot of the zoom so you can see what I mean. I've already reset my Illustrator preferences in case I might have changed something but still nada. :(
