Specialty LED Lighting Solutions for the Graphic Arts and Printing Industry
Promolux now offers professionals in the graphic and printing industry the ultimate LED technology and light sources for color matching, and quality inspection.
Current advances in lighting technology has rendered as obsolete all past methods of measuring quality of light. It is now very clear and well documented that the CRI index developed over 80 years ago was based on 8 color samples and today we measure over 99 color samples (TM 30) and D50 (5000 Kelvin) is no longer accepted as a measure of color correctness.
Many tools have been developed such as spectrophotometers, colorimeters and densitometers and despite their usefulness, these need to be calibrated to each other, the printing methods, inks and paper used… When we compare current equipment to our eyes with approximately 120 million rods and over 6 million cone shaped receptors measuring the quality of light and color, we realize that human eye is by far the most reliable tool and the one by which the client will ultimately measure the final results.
Furthermore we find that monitors and scanners use RGB color pixels to transmit a mix of colors that does not offer a true black and the printing industry used CMYK where color is measured by its reflectance on a white substrate.
Promolux Balanced Full Spectrum LEDs for the printing and graphic industry and all color critical applications are the best way today to perceive colors with maximum saturation, hue, lightness, gamut, color fidelity, and color discrimination as they are created based on the highest Color preference Index possible with today’s digital lighting technology. In addition to this Promolux minimizes metameric failures due to the observer, the illuminant, texture of substrate or geometric considerations.
Now available in many standard lamp sizes that save up to 90% energy over non LED sources and can last up to 50,000 hours, thus paying for themselves through their savings. We invite you to try them today.
