No, they will print looking very fuzzy, grainy, or "pixelated". Images from the web are designed to download on your computer quickly (makes websites seem very fast). Images and artwork intended for print take much longer to download but include a wider range of colors and cleaner edges. You can see an example of web vs vector graphics on our label setup page. High quality artwork is typically produced in vector format (Ai, EPS, SVG, PDF). We do have the ability to vectorize (recreate) your logo -- if need be -- to make it print clean and clear. Please ask.
