Zazzle supports images in JPEG, PNG, PDF, and Adobe Illustrator (AI) formats. These formats will produce great quality products as long as the resolution meets or exceeds our recommendations. We support full transparency for PNG, PDF and AI files. This can be especially useful if you are creating a design with multiple overlapping images such as borders to go around your design, or shapes with non-rectangular edges. For PDF and AI formats, we support vector output for most of our products. Please note that within the Zazzle Design Tool, a rasterized (bitmap) version of your vector-file will appear.
GIF and TIFF formats are also supported. Please make sure the quality of your image is high enough to print on a product.
To ensure your images are the correct size and resolution, we recommend starting with one of the Zazzle Guide Files. These guide files are the correct size and resolution required for great results. Higher resolutions will have even better results.
The general resolution requirements (in pixels per inch) are:
If you have pre-existing artwork, see the complete list of image sizes and resolutions by product type.
To fill the full area on any product, we recommend that you use images that are equal to or larger than the recommended sizes. In the Design Tool, a resolution warning will appear for any images sized larger than the resolution of the image allows.
We recommend using an sRGB color profile for images; however, we also support CMYK based images.
In any image, there are areas that you may want to be transparent (i.e. the area or background behind it shows through) or areas that you may want to be non-transparent. If you create PNG images with transparency, then those transparency settings will be obeyed. In photos, we would guess that no area should be transparent.
But if you have a JPEG image (or PNG image without transparency), you cannot specify which areas are to be treated as transparent. In that case, we let you specify all white in your image as transparent. To do this, under the "Customize It" tab, please check "show whites in image as transparent" on the image module.
You can check your image quality by printing a real sized image from your printer and checking it for any fuzziness. If you do decide to use a JPG image, use the lowest compression factor available to decrease any distortion effects.
