XLimage® guarantees high colour fidelity to Internet users. XLimage®
achieves this important result thanks to a server-side colour management and the profiling of the display device client-side.
The problem of colour portability in digital images is complex and for several reasons not much faced by software manufacturers.
However the demand of a correct colour representation is needed by users and it is fundamental to succeed in complex activities bound to the Web.
The purpose of a colour management system, or CMS, is to offer a consistent colour representation from a device to another one.
A CMS simply does two things:
- It describes pixel colours
- It ranges the pixel values so as to keep the colour consistent from a device to another one.

A system in which the CMS is implemented will include three fundamental components:
- A colour space of abstract references device independent
- Profiles ICC/ColorSync colour for any involved device (scanner, printing, monitor, digital cameras, etc.)
- A Colour Matching Module or CMM (conversion module colour) which task is to interpret the information in each device's profile and to carry out the necessary conversions.
The XLimage® CMS provides correct colours management upon image importation on the server (colour profiles are used to map the image correctly in the abstract colour space LAB).
The system uses the possibility of characterizing the user's device through a simple wizard provided by XLimage®.
Once characterized the user's display, the CMS of XLimage® is able to send images to the display applying the correct colour profile (images colours sent are mapped from a LAB colour space to a specific RGB colour space matching the user's display). In this way a good correspondence is guaranteed to the colour of the original one on a vast range of devices. Notice that display calibration is optional and can be run just once for all.
