What does it means when someone says that they only accept .jpg at a given dpi and file size over a given number?


My interpretation is that they are accepting everything above the given file size, as without a target printing size, the dpi is not meaningful...

So what am I missing?

You might need to be more specific. What was the exact wording? I'd guess that there's an assumed print size in the equation. As you said, DPI means nothing without it.

We only accept electronic files in .jpg format of 300 dpi and a minimum size of 700Kb.

No further tips about size.

It's obvious that whoever set up that specification has no clue about what they really need. You can make any image file have any "DPI" value that you want it to have even if the file is so compressed as to be virtually useless. What really counts is the size, in pixels, of the file and how large the customer wants to print it.

Good, just as I expected. As a newbie, I was not sure if some convension was in use, now it is clear.

I've just sent a request for explanation to him.

Thanks

It means they dont really know what they are talking about!!

DPI means Dots Per Inch, and it is used as a printing resolution (mainly) for inkjets. It in nothing to do with print sizes, file sizes or any other size for that matter!

What your client should be asking for is PPI. Pixels Per Inch. Basically, any images resolution. 72 ppi is screen resolution, upto 300 ppi for printing.

Many people do get them confused between the two but someone who works with images all the time, or a client requesting images, shouldnt.
