At/In highest quality?

I'm currently stuck on the right preposition followed by "highest quality" as in:

"I make sure the posters are printable at/in their highest quality."

Thanks!

Solution 1:

Which preposition you use for the phrase "highest quality" definitely depends on the context. In your poster example, I would go with "in" because "at" implies some sort of location, real or metaphorical, as in "The fruit is at its highest quality directly after it is picked." Although this sentence is a bit strange, you absolutely could not use "in".

But whichever preposition you use, the sentence about the posters still sounds awkward, so you might want to change the sentence around entirely.

"I make sure the posters are printable..." There are lots of different ways to finish this sentence with the general meaning you are going for.

Hope this helps.
