Don't use low res!
Resolution, displayed as dpi (dots per inch) or ppi (pixels per inch), indicates the number of colored dots or pixels that make up one image. The higher the resolution, the clearer and better the resulting print will be.
All files and images must have a minimum of 300 dpi resolution in order to have a clear and high-quality prints.
Most images taken from the web are going to be low res at 72 dpi, we can’t turn a low res image to high res, so you have to make sure the image is bigger than the file you’re working with. Here’s how to do it:
1. Do a Google Image search, click the Search Tools button and then Size drop menu.
2. Here you can choose the size of the image results pixelwise, Large should work most of the times. Keep in mind, the bigger the image, the best it will look on the final print.
When you open the image on your browser, make sure that it covers the whole window, if it appears small then it's not suited for printing.
3. A formula you can use is multiplying your file size by 300. For example, if you want to cover a 3.5 x 2 business card, then your image should be at least: (3.5 x 300) x (2 x 300) = 1050 x 600 px large.
4. You can check an image’s dimensions on your computer by right clicking and choosing Properties on Windows or Get Info on Mac.
