Get top-quality scans from your scanner with Lprof

Filed under

The key to getting first-rate image output on any operating system is setting up a good workflow. One piece of the workflow puzzle that used to be out of reach for Linux users is device profiling -- accurately measuring hardware devices like scanners and monitors to account for their differing capabilities. But a relatively young open source application called Lprof does a professional job at that task.

At good workflow ensures that every stop the image file makes along its journey -- scanner, digital camera, editing software, monitor, printer -- is a known quantity, so the color management system can apply the correct transformation to the image at each step.

Often the very first step is a scanner, which can be quite tricky. Every model is different, there are variations among every device of the same model, and a scanner's characteristics change over time. The way around such problems is to make a scan of a tightly controlled target image for which you know the correct color values. You can then measure the scan against the known values and create a device profile that a color management system can reference for all scanning jobs.

An Everyday Linux User Review Of Chakra Linux 2015.11 "Fermi"

Chakra probably also isn't for you if you are a casual computer user who has chosen Linux because you prefer it to Windows but you still like it to be straight forward with perhaps menus, point and click installers and straight forward connections to your hardware. Chakra might be for you however if you have been using Linux for quite some time and you are looking to have more control, use the command line a little more and have a closer affinity with how things really work.
