Page 34: Introduction To Display Monitor Calibration
| SPECTRAVIEW II - USER’S GUIDE Calibration Overview Introduction to display monitor calibration Computer display monitors display images by giving off light from the screen. On LCD display monitors, light is emitted from a backlight source such as fluorescent lamps or array of LEDs (Light Emitting Diodes) and passes through individual red, green and blue filters for each pixel on the screen. - Page 35 5 | SPECTRAVIEW II - USER’S GUIDE SpectraView includes several industry standard targets for a variety of applications: Target Name Application White Point Tone Response Curve CIE (x,y) (Gamma) Print Standard Commonly referred to as Proofing D50 (0.346, 0.359) Standard. Used widely for the proofing of color transparencies or press output.

Page 40: Outside Of Spectraview
0 | SPECTRAVIEW II - USER’S GUIDE Outside of SpectraView Using ICC/ColorSync Monitor Profiles The ICC/ColorSync monitor profiles generated by SpectraView are used to inform the Color Management System of the color characteristics of the display monitor. Color Management Systems use this information to determine how to display images on-screen. Depending on the image editing software package being used, profiles for printers and scanners can also be utilized to create accurate image prints and scans. -
Page 41: Frequently Asked Questions Calibration
I can do with other monitors? Answer: When used with the SpectraView software, NEC display monitors store all of the necessary color adjustments internally, including the 10 or 12 bit Look Up Tables. The ColorSync utility switches the display color settings by changing the Look Up Tables in the video graphics adapter. - Page 42 | SPECTRAVIEW II - USER’S GUIDE Question: Each time I calibrate my monitor I receive a different Delta-E result. Should I recalibrate again if I receive a value that is high? Answer: For Delta-E values of less than 2 there is almost certainly no need to recalibrate. For values higher than 3 it is important to understand what the cause is, and if it is significant.
