So, you’re designing a logo or graphic for vinyl banners or business signs? Be sure that the image used is in high resolution. Many people make the mistake of making it in 72DPI(Dots Per Inch) and only a couple inchs tall because thats how it looks best on your computers monitor.
When you try and put this on a 36″x48″ vinyl banner, the process requires that you resize the graphic. To keep the math simple we will just say 20 inches, that means that we are increasing the size by 10 times its original size, so now instead of the image being 72 DPI it has now increased the size of the dot to 7.2 DPI, this makes those dots very noticeable. The key here is to have enough dots per inch to where the graphic will have smooth corners and curves. So, the main point is to have enough dots in your image will still have smooth and won’t be grainy when expanded or enlarged.
You can resize the image on a program like Photoshop and even have it increase the DPI, but what happens then is the program will guess as to what color pixels it will add to your image, this causes the image to look fuzzy and it looses detail. A common goal to try and reach is 100 DPI. This setting will allow you to resize without worrying about dots or fuzzy details.
The best solution however, when ever you designing a logo or an image, create it as a vector file, this is the best type of file because this consists of lines art instead of dots, this allows you to increase the size of your image without loosing quality it allows you to change colors in a very simple manner as oppose to a Raster image which makes it harder to manipulate the image.
If all you have is a low resolution file, we can convert most images to vector so you can contact us, and submit your art work for us to give you a quote on converting it to vector so that you can get your sign or banner produced.

So is the vector image still a Photoshop file? Interesting info.
