Before discussing how to profile, lets talk about what profiling is and why you may need it. Most monitors are set to a generic profile, ie colour balance, that isn’t necessarily accurate to the colours captured by your camera. The same image on another monitor or on a printer may look radically different, therefore editing an image and adjusting the colour will probably make the image even worse. So making a new accurate profile will make this much easier.
The step by step wizard of the software guides you through the steps needed to use the Colormunki. The device itself is similar in shape to a tape measure, and radically different in design to other similar tools, A case with a weighted strap is provided, and the device is dangled from the top the top of the monitor by this strap. A USB lead connects the device to your PC.
Once in position, the software produces a series of red, green and blue screens, followed by a white through to black screen with a series of greys in between; The Colormunki measures these colours, and corrects the difference between the colours produced and the actual colours. That difference provides the mathematical data that makes up the profile.
Once this is done, the profile is produced and automatically saved in your PCs colour folder. Over time the monitor colours can change so a regular profiling session is recommended and the Colormunki software can provide a regular reminder to recalibrate your monitor. Finally a before and after screen lets you see how the colour of you monitor has changed,
Next the printer set up is needed, Most profiles provided by printer manufacturers are pretty good nowadays, but changed between batches of inks and papers can produce slight changes in colour, and users of third party papers, such as many Fine Art papers may notice problems. This is further compounded if you use different types of paper, which have different base colours, ink absorption and so on.
