Question 1

How is conversion done in a closed loop workflow?

Answer 1

Looking up device counts of the original colour and corresponding device counts

Question 2

How is conversion done in an open system workflow?

Answer 2

Device counts are converted through profile connection space (PCS) as a common language

Question 3

Source colour space /profile

Answer 3

Device counts before conversion, the associated colorimetric values of the original image. colour

Question 4

Destination colour space/profile

Answer 4

Device counts after conversion, the associated colorimetric values of the resulting image colour

Question 5

Profile connection space

Answer 5

colorimetric colour space, the common language of colour for all ICC profiles; usually Lab*

Question 6

A2B

Answer 6

Used to lookup colorimetric values (B) associated with device counts (A)

Question 7

B2A

Answer 7

Used to lookup device counts (A) associated with colorimetric values (B)

Question 8

Rendering intent

Answer 8

The way colours are remapped to destination colour space
when two device gamuts do not match

Question 9

What two colour spaces are always required to make a colour conversion?

Answer 9

Source Profile and Destination profile

Question 10

Why are ICC profiles useless alone?

Answer 10

There needs to be an engine to do the conversions and work, and there needs to be 2 ICC profiles to compare

Question 11

Are CMYK and RGB enough on their own?

Answer 11

No

Question 12

What is the Colour Management module?

Answer 12

The engine of the ICC workflow, does calculations and navigates lookup tables

Question 13

Apple and Adobe have built in CMMs

Answer 13

True

Question 14

What is the perceptual rendering intent’s LUT?

Answer 14

A2B0/ B2A0

Question 15

What is the relative/ absolute rendering intent’s LUT?

Answer 15

A2B1/ B2A1

Question 16

What is the saturation rendering intent’s LUT?

Answer 16

A2B2/ B2A2
