Take the 2-minute tour ×  I am making an image to be printed on
a 3x4 foot poster.  I am worried that the image will be
pixelated after being printed. Should I use svg to make this
poster? Is this even a valid concern?  share|improve this
question  1 Answer 1  up vote 6 down vote accepted  You want
your image to have the correct source resolution for the print.
If your print resolution is going to be 300 dpi (dots per inch),
then for a 36×44 inch poster, you need a 10800×14400 pixel
source document.  I wouldn't print a document with a resolution
of less than 300 dpi. So, unless your source image has 10800 by
14400 pixels, then you will see pixels in the output, because
you have to upscale it.  It depends on your source though: So,
let's say you have a photo from a digital camera that is 1080 by
1440 pixels, then you have to upscale it by a factor of 10 to
even get to the print resolution. Most upscaling algorithms will
try to "blur" the image a bit*, so you don't get pixels, but
rather a smooth transition. Th
