I have started this thread to give ideas to all members and guest of the forum. My objective is we can educate in exciting way by means of a trivia.

Let me start

R=0, G=0,B=0 > Black
C=0, M=0, Y=0, K=0 > White

If monitor is in RGB, Your desktop printer is what? RGB or CMYK?

Ferdie, thanks for starting this thread. We need experts like you on this field.

This will help round out our understanding of the whole process, which includes printing.

I have a sense that there will be a lot of heady stuff to be posted here.

L*a*b* isn't a device dependent color space. It's not device specific. It's a device independent color space.

If lux is the measure of intensity of incident light, what is a luminance that you measure in your display either crt or LCD?


@ Nino
Lets start with terminologies.

@ Sir Jo Avila
Thanks for Answering

@ other members
Time to ask some jargons

Use the search function of the forum. I already answered that in a past thread :D

Cheers!

Jo Avila

P.S.

There is no such thing as Perceptual Colorimetric. The four rendering intents are Perceptual, Saturation, Relative Colorimetric and Absolute Coloritmetric.

Color Profile or ICC Profile > is the numerical description of a device (input or output)

Color Space > is the assumed profile or assigned profile by Adobe which serves as a reference of conversion which correspond to ICC profiles numerical description.

Metamerism> is define as two colors may match under one condition but not on another condition, and it is said that the two color are metameric pair. My question is, what is the opposite of metamerism?

A human visual system can only recognize approximately 10 million colors in 1 condition. A monitor can produce 16.7 million colors. Approximately, how many colors are there in this world?

Is there a possibility to make this device behave as a cmyk?

There are four(4) Rendering intent namely, perceptual,colorimetric rel, and abs, Saturation. What do you call the measure of the ability of a light source to produce the color of various objects being lit by the source? This is very important in matching a print from a display.

Hmmm... I know that I can cross render or make the output of my ink jet printer mimic the output of the printing press (which uses CMYK) :D

Answer: Color Rendering Index in laymans term, quality of light source.

BTW, all trivia questions here were given and explained during the CMS seminar @ Seawind Boracay, Bacolod and Kalibo.:Grin:

Ans: Drive by a RIP ( Raster Image Processor ).

I will be posting more trivia next week, and if a DPP member (moderator and Admin is not allowed to answer) can answer, there is a prize like maybe a jacket or free.......

Here is the free 18x24 in fineart printing question.

What do you call the measurement in Degrees Kelvin that indicates the hue of a specific type of light source. Please give me the complete technical term.:Mad:

kelvin color temperature?

steve rusling

COLOR TEMPERATURE:

The chromaticity (The color emitted as determined by its wavelength) of an ideal "black body" when it is heated to a specific temperature in Kelvin (K).

It is the measure of the color of light, not actual temperature.

I'll take a stab at this question. Ask for their Color Profile?
