Raster vs Vector

Hi Alex, I always export raster png for printing, sometimes I need to convert these images to jpeg. I have never had a problem with quality.
For my next project though I need to have the image blown up quite large and I am a little unsure how to get the best quality.
I have done some research and I am thinking to export a vector image and convert it to pdf format. Unsure if I should use eps or sgv though. Any advice would be greatly appreciated. I basically just need the best way to have an image blown up without losing any quality, many thanks four you time, Macy

Hi Macy, to obtain the highest quality possible you need to export your cloud in EPS vector format that can be converted to PDF (if needed).

Thank you Alex, Macy :)
