I have a question about the right PPI for projects.
I’m an amateur, self taught graphic designer that does random marketing projects for a law firm that I work at. Recently, I was asked to create an 8.5"w x 9"h poster for a seminar we are hosting. No Prob - it looks decent. Using photoshop, at a higher PPI (240), it prints well, and is a huge file currently.
I’ve been asked to facilitate it being included in various local chamber of commerce weekly paid emails. Each chamber requests it in different sizes (i.e. 568px x 497px) but how to I make sure that the text remains crisp and readable? Historically, it gets a bit fuzzy due to low res. I’ve attached a photo (with our business info redacted - so ignore the black boxes) It is currently 2040px x 2169px @ 240PPI. How do I make it ~25% of that size and retain quality of text and image crispness? The chambers are asking for jpeg files which I thought were not preferable for this type of thing?
