DPI/PPI Indesign

Hi

 

For a project I should create a banner of at least 150 DPI. I have been working in Indesign for a while, but don't know how or where to adjust it. I know you can't adjust the DPI, but you can adjust the PPI.

I have already been told that the photos can be edited in Photoshop to get the correct resolution.In addition, the difference between actual and effective PPI is still a mystery to me.

 

Who can clarify these issues for me?

Thanks in advance!

It's crucial to understand the difference between PPI and DPI. Even a lot of pros — and printers — are soggy in their understanding.

 

DPI, dots per inch, applies only to print. It's the usually the number of ink dots per inch, sometimes confused with the linescreen (LPI, Lines Per Inch, the effective resolution of the print image, usually much less than the DPI).

 

Everything digital is PPI, Pixels Per Inch, and PPI is something of a phantom number at that. No digital image file has an actual P

what i mean is that acronym "ppi" wasn't used in Adobe's UI.

 

Right because they wanted to make it clear that image resolution was measured as Pixels Per Inch (pixels/inch). Image resolution has never been referred to as DPI in the UI.

exactly. but that's how people in the industry referred to image resolution: DPI (as I'm sure you know anyway). obviously, it started before the "pixels/inch" measurement came into use (as you also know).

 

and people in the industry often keep calling it DPI these days as well. the example brought up below by David Creamer is yet another confirmation for this.

 

maybe if Adobe started using the actual term "ppi" in their UI back then it would have helped make the use of PPI more widespread. who knows. but Adobe didn't. and the term "dpi" was already deeply ingrained in the industry by then.

 

we can hate it, dislike it, disagree with it all we want. we can call it "incorrect usage".

 

but we can't change the fact that in actual reality DPI is used interchangeably with PPI when referring to image resolution. and both of them refer to "pixels per inch", of course.

Have you read closely enough here to grasp that no one is disputing you on this assessment of "actual reality' — the millions who hack at imaging and publication, usually while complaining that Adobe's pricing is piratical?

 

Or that if you choose to throw your lot in with the equivalent of flat-earthers, and defend their sloppy and incorrect usage based on a form of 'voting on the facts,' no one is going to try and change your mind?

 

But here in what may be the most concentrated body of experts in the field (both software and practices), it's overwhelmingly preferred to use the terms precisely. Arguing endlessly that we should somehow follow JoeBob's EZ Publishing Blog or ten thousand amateur users who don't grasp the "no soft returns" thing or printers who have been doing this since the lead type days is... well, it's amusing at least.

I'm sorry but I don't understand your point.

 

You're in the industry longer than me.

 

You're well aware that in the 1990s and well into 2000s virtually EVERYONE was using the word "DPI" when referring to image resolution in their communication with coworkers etc.

 

Do you imply that all those people were sloppy hacks and flat-earthers?

 

Or was there a specific date after which all those people had to stop using the word "dpi" and switch to "ppi" to convey EXACTLY THE SAME THING? Otherwise they'd turn into flat-earthers and amateur users? And what specific date would be that, if so?

The point here is that it doesn't matter how many times you insist something is so if it isn't. PPI and DPI are not the same. I learned this decades ago and I strongly encourage you to stop this argument once and for all and get with the program!

Bob, here's your own words:

 

"The fact that many people do use them interchangeably doesn't make it correct."

 

I never claimed that it's correct or incorrect. My point is that PPI and DPI are, in reality, interchangeable.

 

And you yourself say exactly the same:

 

"...many people do use them interchangeably..."

 

YES!!! People do use them interchangeably! That's exactly my point.

 

People use them interchangeably - which means PPI/DPI are interchangeable. Because - as you yourself said - people use them interchangeably.

 

So we both are saying exactly the same thing. Where's the argument?

We are NOT saying the same thing. You're twisting my words to fit your narrative. So, you can go on your merry way thinking they're both interchangeable and acronyms. Neither is true.

 

I'm going to move on because it's clear you don't care about facts.

Regardless of what you have or haven't claimed, "reality" includes what's correct vs. what's incorrect, and cannot be rooted in commonly mistaken misusage.

 

On the contrary, it is indeed in reality, that they are not interchangeable.

Honest question:

 

How they are not interchangeable if people do use them interchangeably?

 

I truly, honestly don't get how these two statements can be true at the same time.

You've made your inability to grasp the difference between common, largely ignorant usage and technical precision clear. There's really, really no need to keep tro... repeating it.

 

Do you sincerely believe mass misunderstanding and ignorance represents "reality"? I can't begin to list things that Joe Q. Public, or even Tiffany J. Designer, intransigently "believe" that are wholly false-to-fact... are you saying their votes trump the actual facts?

 

I suggest this thread be locked as not just useless, but willfully counterproductive.

So may I ask if you believe that the term "leading" should be abolished because it's not "technically precise" (as there are no lead strips anymore)? And that people who have been using the term "leading" for decades after lead strips became obsolete, are ignorant?

IMO, the use/misuse of the terms won't change until the scanner software on multi-function printers change the term. I just purchased a new Canon MFP and the software still says "dpi".

Here is an old PDF that I wrote about the different resolution terminology. Some parts might be out of date but most if it is still good info.
