For your Real-Photo Book, the images aren't printed, but created with light. Just like in classic photographic development. A DLP chip projects your photos onto the Real-Photo Book’s specially coated paper (1). This chip is made up of as many as 2 million tiny little mirrors that can be tilted to reflect (or not reflect) any light used to illuminate the chip. Chips like these can also be found in projectors. The projection triggers a chemical reaction in the light-sensitive silver halogenide crystals in the paper’s coating. This creates a so-called latent image (2). As a result of the subsequent development process, this image becomes visible (3).
This process offers far higher resolution than printing as well as very fine colour gradations, dispensing with a raster. The colours are more vibrant and brilliant, as the colour space (the range of colours that can be depicted) is considerably larger than in printing. The overall result is a more detailed, more brilliant, higher contrast image.
