I'm working with an artist who is sending me png files. According to the printer, these files are to be 825 px x 1125 px at 300dpi. Seems straightforward enough to me. However, the artist keeps sending me files at 1650 px x 2250 px at 72 dpi though I've reiterated what size I need.
Here's the question. Is there a technical reason why, as an experienced artist, he's doing this? Does he know something I don't about pixels and dpi (like maybe this is a non-issue)? Or is he just being a jerk, lazy, or not paying attention? I'm still a novice at graphic design so I want to know if there's a good technical reason why he might be doing this before I make an issue out of it. Thanks.
