Your file must be at least 300dpi or vector art. If your image is below 300dpi, please do not simply increase the resolution. This will result in a very blurry, pixelated image. Ideal full colour artwork will be 300dpi or higher at the size it will be printed.
The bleed area runs along the edges of your document. You will want to extend any background image or colour all the way to the edge, and slightly past it, to prevent any white borders from showing.
When images are taken from a website, they are typically 72dpi. This resolution is not high enough for printing purposes. You may also run into copyright restrictions when using web images and therefore we do not recommend using these in your artwork. The only exception would be if the image was purchased from a stock photo website at a large resolution.
