# TJ:


If I want to make an image a real size (i.e. 3' * 4') what dpi should I use?

# I want to make some brass plaques 3" * 4"
I need them to come out at that size when I feed the images into the engraver - it'll be 12 plaques laid out in a 1' square sheet of pre-polished brass, allowing 2mm for the width of the outlining tool.

# Well the question you will need to ask is, what DPI does the engraving machine require?
I would probably assume you wouldn't want much more than 75 - 100 dpi for that, since it's hardly high resolution stuff..

# hahahahahahah
I hear that so often and it hurts so much

a 3x4 image at 300 Dpi is 900x1200 pixels
a 3x4 image at 400 Dpi is 1200x1600 pixels

The Dpi is only relevent for printing it off at a higher quality.

# Thank you -
I want it to look tidy at 3" * 4" when I feed it into the engraver.

In my experience telling an image to be a certain size in tatty shop has no bearing on the size it comes out.

# thats because you are probably printing it
with a "fit to page" setting or just a printer that isn;t as compatible as it should be.

# Right.
I want a final physical thing which is 3" * 4"

How can I make that?

# by finding the settings for the printer
that make it print at the size of the package.
(Print Options under File in most packages)

Chances are you'll need to do a few test prints, measuring the results with a ruler to be sure.

But 300Dpi should do you for that size.

# Test prints aren't really an option
I'm engravinbg into brass.

# I mean test prints on paper

# then do some tests into some scrap wood or plastic
shoudn't hurt an engraver.

# I have no idea, I just doodle on shop, I don't use it for real work
I'd guess the more the better, depends what you printing it on too

anything over 300 should look decent enough?

shouldn't it?
