Ok, I knew about the Photshop export and save as any kind of file. BUT then it will be rastered and that will decrease sharpness on my drawings. Or I have to set dpi very high which makes the files very big (50mb+) So I would like to keep the file in vector only so that the drawing that I've made is flat. With flat I mean that when the drawing is selected by my client in Illustrator, he cannot adjust anything. And I also thought EPS at first, but when i open that EPS file in Illustrator again I can still change or move lines. Which I don't want. thanks
