how can i find how many dpi a figure is?

I have a research paper and in order to be able to submit it to a journal,
the figures and the pictures that i used in the paper have to be at least
1000dpi. how can i find how many dpi my figures and pictures are?

Hi Chris,

For any images you've inserted into your document, go back to the source and find its dimensions in pixels. Then divide that by the
dimensions in inches of the image as pasted & scaled in Word.

BTW, 1000dpi is a ridiculously high resolution - there's very few people who could pick the difference between that and 600dpi for
B/W line art or 300dpi for a typical photo. And if the printer only outputs at, say, 600dpi, anything more just adds to the file's
bulk without being printed. Vector graphics print at whatever resolution the printer is capable of.

Cheers

Not an unusual requirement for fine printing processes. Printers set their
own requirements and they are often high. 1000dpi isn't that high a res as
printer requirements go.

AFAIK you can't, from Word, at least. You would hvae to look at the graphic
in an editing application and check the resolution there. In digital camera
lingo, a 2 megapixel or higher camera will create graphics of that caliber;
a 1 megapixel would not.

Caveats:
-- You might want to check on this with the powers that be, but ... to
prevent the image from suffering resolution changes, you should LINK to the
images from Word as opposed to embedding the pictures into Word. Else Word
can change the res on you. The printer will have requirements for which
he'll accept. At any rate, be certain to NOT let Word optimize the images
if you embed them.

-- Irfanview is a freebie image editor that will let you see the
resolution.

-- Do not confuse ppi (pixels per inch) with dpi. Pixels and dots are two
entirely different concepts, one for the screen, the other for the printers.
DPI is consistant from printer to printer but PPI, which a printer doesn't
use, is completely variable on-screen and has no set size unless it's
interpolated for a particular printer.

That figure will vary with the particular printer installed for any
particular computer. It's the printer drivers that determine what dpi max
can be printed, and Word uses those specs internally for its displays.

That's partly true, but ... printers often have such requirements and as
printers go, that's not a high resolution. 3 Megapixels or about 2000 x
1500 pixels is common for images and then you have to convert that to dpi
for the printer being used.
