Of course the same applies to the walls of our work space especially when it comes to the space where the screen will be placed for color processing or softproofing. There is no point in using D50 fluorescent lamps if the walls or partitions in our office are brightly colored. We must realize that the work of graphic arts has its own rules of decoration and… clothing. Its futile to do color correction in front of a screen wearing a red tshirt or fluorescent green polo. The walls are recommended to be painted with MunsellN8 or MunsellN7 or MunsellN9 neutral grey.
In the Munsell color system the MunsellN8 neutral shade corresponds to a black percentage of 19. Lamps Placing our screen in front of a window should be avoided. As in the classic darkroom so in the digital one windows should be avoided. The lighting of the space must be done exclusively by photo background removing artificial lighting 5000 0 K without any presence of natural lighting as far as this is possible because the lighting from the windows constantly changes during the day and does not ensure constant conditions of light intensity and color. The goal is to ensure stable lighting conditions throughout the day but also at night.
Because D50 or 5000 0 K lamps are very expensive and hard to find for 5000 0 K lighting use there are affordable fluorescent lamps on the market with a good CRI index 98 from Philips and Osram but also from other companies with a color code of 950 p .x. PHILIPS Graphica Pro TLD90 58W950 or OSRAM ColorProof L 58W950 or even the OSRAM LUMILUX DE LUXE L 58W954 CRI90. The number with W only shows the wattage of the bulb and we can also figure out its length proportionally.
