I get a lot of questions about the different file formats, so I figure I can go through them one at a time. I guess to start the discussion, we should really go from the basics. There are two types of art files, vector files and bitmap or raster files. Illustrator and
Corel are the most popular vector art programs. Vector art is
mathematical, it is geometric definitions of the designs, which allows those file to be
infinitely scalable. Bitmap, or raster images are grids, and each square in the grid is defined by a color. You can easily turn any vector file into a raster file, but going back is a lot more difficult.
That being said, no organization should be stuck with a
jpg alone, but
jpgs are great files. They can be used on the web, inserting into word files, or even into
powerpoint documents. Now sometimes, you may try to insert a
jpg into a word document, lets say, and you will only see a black box, or a box with a red "X". This normally means that the
jpg is in the wrong color format,
CMYK instead of
RGB, but those are later posts. The
jpegs are set restrict by the size of those blocks, known as dots per inch or
DPI. The number of dots, or color blocks, per inch determine how crisp the image is. If there are only 72 dots per inch, as is the standard on the
Internet, can not be used in professional printing, which has a standard of 300 dots per inch. What does that mean, please don't pull a logo off of a website and try to print it in a brochure.
