Paper brightness

Essentially, brightness is referring to the print contrast of the paper, which affects the image quality. Note that these controls work differently on other display types, such as CRTs. The BriteXP Probe Series also has a 0 to 99 relative intensity display range, and offers a 25mm glass window spot size, light source of either nm or nm, and mm sensing distance.

Yes Sorry, something has gone wrong. Like what you are reading. These factors should be considered when choosing an appropriate stock for products. They are just one of many such industry leading sensors from EMX, alongside other standout products such as color sensors, luminescence sensors, opacity testers, and more.

The BriteX brightness sensors are a step ahead of the competition, and help the companies who use them to stay a step ahead of their competition as well.

This is why two lamps having the same color temperature can still show differences in color as seen by the human eye. Sign up for our free newsletter I agree to the Terms and Privacy Statement. Two lamps whose x,y co-ordinates fall one above the Blackbody curve and one below could have the same CCT.

The quickest way is to shine a black light on the paper.

It is more accurate than brightness with regard to the human perception of shade. All possible colors then fall under a "guitar-pick" shaped triangle in which the perimeter encompasses spectrally pure colors seen in nature only in rainbows and prisms ranging from red to blue.

For your print information: Opacity and brightness

The three major shades of paper are: You should be aware of some issues with this paper though. Grades with limit values and target values can be set as required. The color points traversed by an incandescent object as its temperature is raised can be plotted on the CIE Chromaticity diagram as the "Blackbody curve" and occupies the central white region.

Most coated papers are currently manufactured to a blue white shade. From there, each model in the BriteX family will offer different specifications, and different real-world applications. This method is applicable to all naturally-colored pulps, and papers and board made therefrom. The BriteX is commonly used for labels, reflective surfaces, plastic products, carpet and registration marks.

All of this makes BriteX sensors extremely convenient and flexible, enabling each to be simple to work with in any existing operation or in-line factory setup. If your order cannot be fulfilled you will be offered an alternative or given a refund for the unavailable product s.

The instrument has a relatively large specimen aperture for the purpose of averaging small area variations in reflectance, making it possible to obtain a reliable average value with only a few individual measurements.

Color is complex; attempting to describe the lamp color with just one number or even with two numbers does not provide total information on how different materials will appear under that light.

The instrument is simple to operate with measurement table, and easy-to-use software.

Since luminance values are not commonly encountered, some example figures may be usefully illustrative: It has a sensing distance of up to mm, nm LED, spot size of 50mm at mm and a display range from 0 to.

Colour, Brightness and Opacity (Paper) These surface optical properties are used in most specifications to define the visual quality of plastic, paper and board.
