How do I change the ppi to dpi in AI CS6?

[happie_97]

Go Effects > Document Raster Effects Settings > Check your preferred dpi

The question makes no sense.

Which kind of resolution do you want to change and what do you want to achieve?

Vector graphics is resolution independent with the exception of placed raster images and raster based effects.

I think the main reason for a community is to help. My default in illustrator is ppi but I also need my file to be in dpi which isn't a straight forward process at all. 

Why shame someone for asking for help especially when the question actually does make sense. HOW do you convert, create, change (or whatever the process is) resolution from ppi to dpi? 

If you're an expert, which you seem to be proving, then you should understand this question and or what the person was trying to accomplish. 

[John Mensinger]

Well, while I'd agree with Monika that your question is erroneous in nature, at least it seems to acknowledge that ppi and dpi are not the same thing, and should not be used interchangeably, as they are all too often.

DPI = Dots Per Inch; a measure of physical printer resolution, and not under your control via Illustrator.

PPI = Pixels Per Inch; a measure of raster image resolution.

There is no direct or constant conversion factor between the two, and so there is no need for you to seek out a method for doing so.

Thanks. Now I won't ask that question again... God Bless

You're answer was also not in context the the mission of the quesiton.

Please re-read this post:

Image resolution is measured in ppi, not dpi.

Vector files don't have a resolution at all.

Only raster elements inside vector document have a resolution, which is measured in ppi.

dpi is the unit to describe the resolution of a printer.

Why do you think you need to define image resolution in dpi?

By @Monika Gause

With that in mind, please post exactly what you are trying to achieve.

[Cory Woods]

This is a helpful and respectful response by Monika. My reply wasn't to her post thougth. I can be a little frustrating when a forum is for people to learn and help and some answers can be a bit condescending is all. 

Cheers!

This is what I'm interested in really. Why do you think you need to covert PPI to DPI, and in what context?

I think you confuse expertise with fortune telling.

When I go to Go Effects > Document Raster Effects Settings > Check your preferred dpi - I don't have any dpi options, they are all in ppi and only giving me RGB, Grayscale and Bitmap.

I've got my proof at working CMYK but can't see what else needs changing to make sure I'm given the dpi instead of the ppi settings.

Any suggestions appreciated.

[traceyd56238804]

I'm getting my image printed and the printer needs the files in 300dpi.

There's a tutorial to change dpi, or at least check it's at 300dpi, at How to Change DPI in Illustrator - YouTube Problem is, I only get ppi at that menu, not dpi. (Hence my question and I think the original question was probably about the same issue).

How do I check that my print resolution will be 300dpi? Or do I trust it will be ok anyway because it's all vectors?

[Test Screen Name]

When the printer says 300 dpi he or she means the same, exactly, as 300 ppi. Many people get quite wound up if people swap over these terms, but I'm a great one for precision and I couldn't care less and will swap them. Freely. Since they measure (as people now seem to assert) in different contexts there is no ambiguity, except perhaps when scanning. I think it's really a way of spotting and picking on the inexperienced.

Let's hope it.

I tend to give everyone the shadow of a doubt, but professional prepress and printing people should be able to tell these apart. And especially when they're writing instructions for the inexperienced they should have taken a look inside the software they're talking about.

Let's.

The units dpi and ppi being wrongly used interchangeably is what caused the confusion that gave rise to this thread (which is pretty ambiguous itself), in the first place.

Hi Tracey,

If it's all vector, you should not worry about the print resolution. I completely agree with Monika in this context.

This question is extremely relevant if you're trying to send an image as part of an email and most of your subscribers use Outlook desktop. Outlook can only handle 96 DPI. If an image is more or less than that, the backward software will re-render the image in 96 DPI.

Even Adobe has problems with sending proper emails to Outlook clients. Images within their promotional emails are often of low quality when opened in Outlook (regardless the version).

So yes, this question makes 100% sense, because Microsoft (among other email client providers) forces marketers and bloggers to downgrade their emails.

And no, I don't have an answer. I was just bothered by the answers given here.

[Doug A Roberts]

if outlook actually says DPI, it means PPI.

[WorkFlowWise]

Outlook doesn't say anything about this (as far as I know). I've found nothing in the entire Help section about it. In addition, I now know Outlook's technology is based on outdated 1993 Word software. To make matters worse, DPI or PPI scaling is apparently influenced by different versions of Outlook. This makes implementing a simple solution even harder. It's debated in detail in the comment section of this article: Mystery Solved: DPI Scaling in Outlook 2007-2013 > Litmus

Perhaps I'm overlooking the solution. Admittedly, the frustration is not making me a better person.

[Test Screen Name]

What do you mean by " the backward software will re-render the image in 96 DPI."?

[WorkFlowWise]

Outlook uses Word-technology to compress images before sending an email and rerenders the image upon delivery. This causes the image to lose quality and has been a problem for a long time. Only the newest version of Outlook now supports SVG images, but not older versions. So there is just no single solution (as far as I know).

[Monika Gause]

So let's summarize:

Micorsoft developers can't tell dpi and ppi apart

On top of that they scale images through some weird algorithm that is not documented

The result is that HTML e-mails look bad in Outlook.

But you are "bothered by the answers" given in this thread?

[WorkFlowWise]

Thanks for the question

Yes, because the original question did make sense to me in a sensemaking and non-erroneous way. I felt that some of the answers given didn't take the question seriously. I am also bothered by the way Outlook handles images. Those are two very different things.
