Print quality of Advert

Hi,

I made an advert and sent to client as JPEG.
The client wants to print it - how should I save it as top quality so that the print is super clear?
The JPEG is blurry when you zoom in…

Thanks.

have you tried saving it as a pdf instead.

Yes I did. But when I save as PDF what should I do to make sure its high quality?

If you designed it in Illustrator you wont have a problem. If its in ps make sure your saving it at hi res. like 300.

in indesign as far as i was taught, pdf ‘press quality’ is for commercial printing, ‘high quality print’ good for home printing
