| What do color management systems do? |
|
Definition
- assign specific color meaning to RGB and CMYK values
- change RGB and CMYK values into numbers that can be sent to our various devices to keep colors consistent |
|
|
Term
| Profile Connections Space (PCS) |
|
Definition
| gives color an unambiguous numerical value in CIE LAB that is device independent and reads the way that we see color providing a link between input and output |
|
|
Term
|
Definition
| describe the relationship between RGB and CMYK control signals and the colors those signals produce as well as defining LAB values that correspond to a given set of RGB or CMYK numbers |
|
|
Term
| Color Management Module (CMM) |
|
Definition
| color engine oversees RGB or CMYK conversions by working with color contained in the profile |
|
|
Term
|
Definition
| Used to fix out of gamut colors by compressing the source gamut while preserving color relationships |
|

Term
| What are the 4 Rendering Intents? |
|
Definition
Perceptual
Relative
Absolute
Saturation |
|
|
Term
| Absolute Rendering Intent |
|
Definition
| Used mostly for proofing, makes the whites a light bluish color to preserve the over all look on a yellowish paper |
|
|
Term
| Perceptual Rendering Intent |
|
Definition
| tries to preserve all colors by desaturating the colors in the source space so that they fit into the destination space while preserving overall color relationships. works best with a significant amount of out of gamut colors |
|
|
Term
| Relative Rendering Intent |
|
Definition
| sets the white point to be the paper being printed on and clips out of gamut colors to the closest color that can be produced which preserves more of the original color |
|
|
Term
|
Definition
| not concerned with accuracy so much as it is concerned with preserving vivid colors from source to destination. good for business graphics |
|
|
Term
| Which is better -- Assigning a profile or Embedding a profile? Why? |
|
Definition
| Embedding a profile because it doesn't change the values in the image but instead tells the Color Management System how the color values need to be represented. This will stay the same from one device to the next and will open automatically. |
|
|
Term
| If the color spaced is changed, will the image change? Why? |
|
Definition
| Yes! If the color space is changed the way the image looks will change because you are selecting a different way to view the image. However, the RGB values will not change. They are just being viewed in a different way by the color space. |
|
|
Term
| What to CIE LAB and CIE XYZ represent? |
|
Definition
| PERCEIVED color, how a person will see it |
|
|
Term
| What would happen if there were no profiles? |
|
Definition
| There would be NO communication between devices |
|
|
Term
| Which is larger? Table Data or Matrix Data? |
|
Definition
|
|
Term
| What is the largest color profile? |
|
Definition
| Adobe RGB because it has table data for the rendering intents |
|
|
Term
| What information does a device profile contain? |
|
Definition
Gamut
Dynamic Range
Tone Reproduction Characteristics of the Colorants |
|
|
Term
|
Definition
| a method for calibration and profiling that sends a target of known color signals to a device to calibrate or profile |
|
|
Term
|
Definition
| a method for calibration and profiling that measures the color signals sent from the stimulus |
|
|
Term
|
Definition
| changing a devices behavior to receive a desired state so the device remains consistent and accurate results are achieved consistently |
|
|
Term
|
Definition
| the process by which we RECORD a devices behavior. DOES NOT ALTER A DEVICES BEHAVIOR |
|
|
Term
| What are 3 variables that need to be controlled during Calibration and Profiling? |
|
Definition
1. Software settings - turn off all auto functions
2. Media (i.e. ink and paper) need to be consistent to attain consistent results
3. Hardware settings (i.e. monitor)- don't change brightness and contrast because the color will shift |
|
|
Term
|
Definition
| making sure printer nozzles are aligned |
|
|
Term
| What is a one way profile? |
|
Definition
| a camera or scanner, only sends profile into destination |
|
|
Term
|
Definition
| a monitor or printer, sends profiles back and forth to convert colors and color spaces |
|
