Does it matter if the image I upload to PrintShrimp is a PNG or JPEG (or even PDF)??
Is there any difference in the quality of the poster between the different file types? I am currently uploading PNGs but occasionally the file size is over 50mb with these so I am having to convert to JPEG, which is a far smaller size file but still in the correct dimensions for 300dpi image.
What does everyone else do??
