The Difference between PPI and DPI - Please get it right!

Recommended Posts

Why in the Document resize window is the resolution referred to as DPI, when it should be PPI

 

DPI is Dots per inch, which is a measurement of PRINT resolution. PPI is Pixels per inch is image resolution and what it should be. This is a fundamental error.

 

For credibility reasons this needs to be changed.

...and what if you are creating a document for print that is not measured in pixels?

That should be done in the print options menu. It is simply confusing to have it here and wrong it refers to ppi and not dpi. This dialogue box is for image output (not print). It defaults to 72 dots per inch....think about it, it would look pretty bad!

I agree, strongly.

Is there a document for print that is measured in pixels?  Are there papers measured in pixels?  Can I get tea in a 20 pixel cup?  The document size has almost nothing to do with the print size, so DPI just doesn't make any sense.  No professional print project from a digital file created at 300 PPI should *EVER* be *printed* at 300 DPI, it would look absolutely terrible.  So, there is no reason to describe the digital file in terms of DPI, accept to allow the people ignorant about DPI to continue being ignorant about DPI.  (With respect, sir, it's absurd.)
