If you don’t see a red exclamation mark appear when using the IXXI module, your images are of a good enough technical quality. If you do get a warning, however, this means that your images do not have the right quality or resolution. In short: the image quality is not high enough, which will result in the print looking pixelated or somewhat gritty.
Quality requirements enlargement
Enlargements are possible with 20x20 cm cards. For the best results, use an image that has between 500 and 1000 pixels. If your image is five cards wide (100 cm, each card measuring 20 cm x 20 cm), then the image should be between 2,500 and 5,000 pixels.
Quality requirements collage
You can choose between either 10x10 cm cards or 20x20 cm. If you choose to use 10x10 cm cards, you'll get the best results if your image is between 280 and 500 pixels per card. If you want to use the 20 x 20 cm format, you'll get the best results if your image is between 500 and 1,000 pixels per card.
Don’t forget to check the image’s aesthetic quality as well: is it in focus? This is not measured by the module. You can check for sharpness by zooming in on the image on your PC or smartphone.
