What is the best resolution for image files?
Images with 300 dpi are ideal. A high dpi is optimal for fine art prints because the more dots of colour that can be printed in a small area, the more detailed your final image will appear.
Other products such as canvas may require lower image resolution. The specific dpi for each product can be found on the individual product pages.
What does ‘bleed’ refer to when it comes to images and printing?
‘Bleed’ refers to the area which gets trimmed off after printing. This is to make sure that the image goes to the edge of the printed product so that there are no unprinted edges. Photo prints usually have 3mm of bleed. However, our print API will automatically prepare your images with the correct amount of bleed, if you aren’t setting up your files independently.
What type of image files do you require?
We can work with a very wide variety of image file formats although our preference is for level 10 JPEG files or PNG’s, depending on the product.
We use JPEG’s because the compression is very efficient and designed specifically for saving photographic and fine art images. Although some image data will be lost during the compression process, at high quality levels there is no meaningful difference between a level 10 JPEG and a Tiff printed to paper.
PNG files have built-in transparency but can also display higher color depths, making them ideal for t-shirt graphics.
Other file formats such as PSD and PDF are unfortunately not supported at this time. If your design has a transparent background, you can retain this with TIFF or PNG.
TIFF is not currently supported for API or manual order form orders.
What file size do I need for printing good quality prints at different sizes?

How do I set up my artwork so it prints correctly within the product shape?
If you download the template for the product and size that you’re creating, it will highlight how much of the image is used as bleed.
Once you’re happy, you can then save your image and remove the guide layers before using it to create your products. If you’re intending to offer multiple sizes, we would recommend doing this for the largest size you expect to offer, as our print API can then scale the image down for the smaller sizes, saving you repeating these steps for each option offered.
How will you protect my images and intellectual property?
By submitting content to our platform you are giving Prodigi a worldwide, non-exclusive license to use your image files to produce your orders. But only your orders. We can not use your images or artwork in any other capacity.
You retain full ownership of your content as well as maintaining all other rights associated with your digital files and any intellectual property rights or other proprietary rights associated with your content remain yours. You also guarantee that the content is owned or duly licensed by you.
Having produced your orders, all images will subsequently be deleted from our systems subject to our data protection policies. Typically, around two weeks to ensure that we retain the file in case any reprints are required for lost or damaged orders.
What are your quality control processes for reproducing images?
We go to huge lengths to ensure your images are produced to the optimum quality possible; whether produced in-house or outsourced using our global print network.
We regularly colour proof test prints across our network to ensure machines remain consistently calibrated, measure all defects and complaints received by every individual lab, and churn any poor performing partners.
We believe we’ve created the world’s largest fine art print network and no one is able to provide you or your clients with our reach or attention to detail.
