Most calibration programs will default to a 6500K white point setting, which is a cool “daylight” white light. This setting should be natively achievable by any monitor. Using this method, the monitor luminance might be as high as 140-150 cd/m2. As well, print display lighting is always adjustable in its intensity. Although the light in this area may differ to that of the final print destination, it’s useful to note that monitor calibration is never quite an exact science. Matching the print-viewing areaĪnother way printers set monitor luminance is to match it to the lighting of a dedicated print-viewing booth or area. This is about finding what works for you and your gear. Potential downsides include a degraded monitor image since not all monitors can achieve this low luminance level without ill effect. The idea is to hold a blank piece of printing paper up next to your screen and lower the luminance until it matches the paper, or just set a low level so that this is more likely. Many printers set their monitor luminance very low. In controlled situations, this feature is needless and even unhelpful. Some calibrators will read ambient light and set parameters accordingly. ![]() If you’re forced to edit in a bright setting, luminance must be raised so that your eyes are able to see shadow detail in your images. The monitor should be the brightest object in your line of vision. Ideally, you should control the ambient lighting in your editing area so you’re free to set the luminance you want. The setting you use is not critical unless you are explicitly trying to match the screen to a print or print-viewing area. Most monitors can reach that level using the OSD brightness control alone, without resorting to reducing RGB levels and gamut. 50% brightness) is that their meaning changes over time.Īlthough arbitrary, the 120 cd/m2 setting that most software defaults to is a fair place to start. The trouble with using onscreen monitor settings to do this (e.g. You need a calibration device to measure the luminance of your monitor and always return it to the same level, as the backlighting slowly degrades. Aside from making screen-to-print matching hard, this reduces the monitor lifespan. A new LCD monitor is usually far too bright (e.g. Monitor luminance is measured in candelas per square meter (cd/m2), sometimes referred to as “nits”. ![]() Expensive monitors tend to allow more in the way of hardware calibration, enabling a higher image quality. The former may cause problems in some cases, which is useful to bear in mind. Software adjustments are the ones that go through the graphics processor, while hardware adjustments are those that bypass the GPU and address the monitor directly. ![]() Ideally, you don’t want this, since it eats into the monitor’s gamut (the range of colors it produces) and leaves it open to problems such as banding.Īlways use software that tells you how bright the monitor is and lets you adjust it interactively. The above is only untrue if you select a luminance setting that is lower than your monitor can naturally reach, in which case a software adjustment comes into play. You are basically altering the backlighting with a dimmer switch. One thing to know about monitor luminance (or brightness, in simple terms) is that it’s typically the only genuine hardware adjustment you can make to an LCD monitor. In this article, we’ll look at six aspects of a seemingly dark art, and how to calibrate your monitor. It’s just a question of breaking the subject down. Perhaps it is, but you’ll soon be comfy with it if you can grasp some of the basic principles.
