A colour profile is a set of data that characterizes a colour profile, such as sRGB. Every photo is assigned to an ICC profile, which defines the colours that are being displayed on an image. Depending on the photo camera and the photo editing program, different colour profiles are used. We print all our products with the CMYK ICC profile.
For printing, all images are converted automatically to a CMYK profile. The conversion from another colour profile to CMYK may result in a slight loss of colour. This happens when the colour profile you use has a wider colour range and therefore all the colours that fall outside the range of the sRGB profile will be converted to a colour that is closest to it within the CMYK profile.
If your photos have been modified with a different colour profile, this may create a difference between the picture on your screen and what you will receive.
Why does albelli only use the CMYK profile?
As a manufacturing company, we must make a choice for an ICC profile. The CMYK colour profile is by far the most commonly used profile and is also our choice.
Saving the photo book as RGB instead of CMYK makes the file size more manageable. This in turn reduces the time is takes for the file to be uploaded. Our printers then convert the photos into the CMYK profile in order to print them at the best quality possible.
What can I do when I use a different colour profile than RGB?
Unfortunately, it is not possible to use photos of the CMYK profile in the software. The photo book is saved as RGB, because this is the profile the photos are saved within the camera.
To solve this, we kindly suggest you adjust the colour profile in an external program, like Photoshop.
