To ensure your designs are produced with the highest level of clarity and colour accuracy, we accept the two most reliable industry-standard formats: PNG and JPG.
Why we prefer PNG
For the absolute best results across our entire product range, we recommend using PNG files.
PNG is a lossless format, which means it preserves every single pixel and detail of your original design without any compression. When you use a PNG, you can be certain that the fine details, sharp edges, and subtle gradients in your artwork remain perfectly intact from your screen to the final print.
Superior Detail: Because no data is discarded during saving, your artwork stays as crisp as the moment you finished designing it.
Transparency Support: PNG is essential if your design requires a transparent background, such as for garments or certain custom-shaped products.
High Contrast: It is the ideal choice for text-heavy designs or illustrations with sharp lines that might otherwise appear "smudged" in other formats.
When to use JPG
While PNG is our preference for quality, JPG is a practical and widely used alternative, particularly for photographic images.
The main benefit of JPG is that the file size is significantly smaller, which makes uploading large batches of images to the Papello dashboard much faster. If you choose to use JPG, ensure it is saved at the highest possible quality setting (Level 10 or above in Adobe) to minimise the loss of detail. Once printed onto paper or canvas, a high-quality JPG is often indistinguishable from a larger file to the naked eye.
Metallic Foil Prints
Our metallic foil products can be submitted in either PNG or JPG format. The technical format is less important here than the colour; for the foiling process to work, any area you wish to be foiled must be 100% black.
You can find more specific guidance on preparing files for metallic foiling on our dedicated help page.
