RE: Scanners, PPI vs DPI, does it really matter?
In a recent conversation as to which scanner to get a few people went off on the tangent of referring to dpi versus ppi. The scanners used dpi long before digital photography was the rage, hence it's just the way it is according to one group of people. But they're not printing anything but capturing to display so it's pixels per inch according to the other group of people.
If you know what both are, do you really get confused if someone mispresents dpi or ppi? Or is it like when you're talking about gas for your car, if someone says regular you don't really think their putting leaded gas into their newer mini-van do you?
What's the point of it all?
Tom, you say that it would matter when specifying to a print company. So I'll ask you this. when was the last time you ordered a print and it asked for the dpi? I've never seen it. In fact, I worked as a screen printer for close to 5 years.
If you sent a file to a print company and specified that the file be printed to a specific ppi, with no cropping, at a certain print size and the file worked for that I'd be absolutely shocked if they asked what algorithm that you wanted to use to convert the ppi to dpi.
Phi: if you're confused between DPI vs PPI then you must think there's a difference. As such I'm assuming that the difference is between being printed and being displayed on a screen. Then I ask you this follow up question.
Is a photograph a picture?
FYI I am not the person doing the thumbs down. I see no reason to do that to any of these answers.
