GIF / JPG in 120 DPI
LtCom...@gmail.com
We have a requirement from a client to batch convert EPS and TIFF files
to 120 DPI GIF and JPEG files. The problem we face is that we do not
find an option to save the GIF in 120 DPI. We only see a maximum of 72
DPI.
1) Can this be done in Illustrator (save EPS, TIFF -> 120 DPI JPEG /
GIF). If it can be done, I am sure it would be possible to script it
using VBScript (we have a Windows version of Illustrator as well)
2) This is slightly off topic, but if Illustrator cannot do this, can
somebody please suggest an alternative software that will be able to:
a) Convert EPS, TIFF to 120 DPI GIF (Image Alchemy doesn't do this
either and the size of the converted image becomes greater than the
original image at the maximum 72 DPI possible)
b) Feature a command line interface so that we could program the
software to suit our needs. We would need to be able to read the
resolution, dimensions of a TIFF / EPS file and convert it to GIF / JPG
accordingly. So, a TIFF (say) 5" wide would be processed differently
from a TIFF that's 10" wide. If the dimensions, resolution can be
revealed using a command line function, that'd be awesome!
>From all my research, I couldn't find one proper software that does all
of this, especially processing EPS files. I have tried GFX Alchemy, Rea
Convertor, Illustrator and so on. Rea Convertor provides the command
line functionality but the quality of conversion is not good.
Would be grateful for leads / advice.
Thanks a lot.

Not sure what you or your client want to achieve either, but Photoshop
does it.

They want a 120DPI GIF resolution for displaying on the web. As evident
as it is, I am not well versed with graphics either. I do the IT work
and this "requirement" was given to us by our customer service
department! If 120DPI can't be done, how would Photoshop do it?

Web resolution is 72 dpi. ALWAYS. No matter what dpi you save it at, web
browsers will automatically default GIF's to 72 dpi. Saving it as
anything but will make it look terrible online (since the browser will
have to resize it, which is never a good thing).

>>Well, screen display resolution is stated in pixels per inch, not dots per

Again it all depends.
Making a PDF for the web is different for instance. Sometomes it helps
to higher the resolution of graphics and the browser/screen/computer can
not touch that.
But it is true. 120DPI is a crazy assumption for direct web. Even 5 DPI
is enough;)
For Vince: no clue how Photoshop does it, Photoshop just gives that
opportunity. I can imagine that is for being prepared to do something
in ImageReday or whatever. No clue. Again: for web (not speaking about
PDF and such) it is totally unnecessary. And since Illustraor is vector
not raster, it has very little to do with DPI or wha have you. I'd say
go back to customer service or better yet: give them oinm screen a 72
and a 120 DPI and a 5 DPI sample.......no difference.

BUT!
You'd have to "save as" to maintain the resolution like that. If you
choose "Save for web", Photoshop automatically adjusts the resolution
for 72ppi.

Yes it does, so what. It is well known default for JPEG's and GIF's.
Sorry, I was tired and not that clear.
But reading the OP again I am still in the mist. What does he want.
I am assuming his boss wants him to convert images to GIF 120 DPI for
the web.
I just state that 120DPI is a rediculous assumption for monitors. 72 is
what the monitor business makes of it.
Try importing an image into Photoshop or whatever and make it 5 DPI or 2
for the sake of it, leave size in inches or centimeters the same, do not
extrapolate. The result is the same.
Repost of this site, scroll down a bit, it is very informative:
