What the... Vector?
Updated: Sep 29, 2020
What if you are asked to provide a logo or illustration in vector form and have little to no idea what you are being asked for? Not to worry, here is the lowdown.
Imagine your logo being used at a size of 10mm in width on a letterhead, and then imagine your logo being used on a billboard. At the smallest size you will not easily see any imperfections, but at a larger size your logo will pixelate (a block-like display with poor visibility). Below is an example of a non-vector image.
If supplied in vector format, your logo can be stretched to any size and the quality will be exactly the same in visibility as in the smaller size, with no imperfections at all. Vector files are usually in PDF format, or in the format of the program it was created in (an open file) so that other designers can access it to make adjustments according to your instructions (this file will normally end in .ai or .eps). Below is an example of a vector image.
Although vector files are used by designers, you do not necessarily have to use them when working in Microsoft programs where it will be displayed in a small size.
Always be sure to ask the relevant employee or designer who created the file to supply it in vector format and keep them on record for future use.
Here is an image which shows a clear difference between the two formats.
