Why Do You Require Color Calibration?

It is a fact that as the price of business and end user display technologies is edged lower and lower, there have to be cuts made somewhere to continue to sell products. In the past, sets were designed with low tolerance parts and thouroughly aligned by technicians before even leaving the shop.

now, the demand placed on manufacturers for quantity, cost, and volume dictates that as an overall whole, they use more generic parts of slightly lower tolerance. Modern electronic circuitry is pretty sufficient at automatically compensating for these variances and allows a large volume of units to be manufactured without requiring a lot of manual adjustments and tweaks.

Depending on your specific application, “pretty close” color reproduction may be all that is ever desired and your display can certainly provide an adequate level of performance right out of the box.
You need to seriously think about color calibration in the following cases:
• Projected/Displayed material must match colors of printed material (logos, graphics, etc)
• Two images are beside each other or in close proximity showing similar material
• Color range is desired to distinguish data sets (seismic, strip logs, geographical data)

Color perception by the human eye is a complicated topic consisting of a lot of physics and biology. To save some time, I will summarize by saying the following: The human eye’s reaction to the color spectrum is not sensitive enough to record quantifiable measurements. You can tell something is “blue” but just how “blue” is it? To top that, different people will have different perceptions of certain colors.

So who is right? The ONLY way to be confident that your colors are being properly shown is to have your display calibrated using sophisticated test gear that will quantifiably measure color. This involves using a special colorimeter unit that takes output measurements of a known source fed into your display or projector. With this information, we can fine tune some advanced settings that control color reproduction on your display/projector to enable it to output a balanced spread of colors across the spectrum.

Believe it or not, the white balance is a major factor in how color reproduction is balanced between two displays. This is the ability of the device to show varying shades of gray from black to white. Again, this is a very subjective measurement by the eye and requires the aforementioned colorimeter to properly measure.

As you can see, Color calibration is a highly skilled task that is best left to the professionals. Contact Engineered AV today to request a consultation on how we can help you improve your image.
