RGB color for Illustration

Let�s say we need to print three color swatches showing the RGB components,

i.e. Red, Green and Blue.

<p>

Now if we use the pure colors (naturally) they won�t print anything close to

what they look like on the screen. The Red will be �Tomato� the Green

pale �Raincoat green� and the Blue will turn into a sickly purple.

<p>

A Hue and Saturation move won�t really solve this problem.

<p>

I�d like to know how to simulate these colors as clean as I can. Any

suggestions?

<p>

G.S.

I'm not sure what you're trying to do, but you must be aware that there are several definitions of Red, Green, and Blue, and for also, for primary colors, as well.

I wouldn't start with Hue/Sat, I'd use the color sampler and the info pallet.

Rendering colors is one of those things that I'd rather not do without a practical purpose, and given a purpose, I'd fudge it to make it work, not neccessarily what is reality.

Good luck.

Which RGB? Adobe RGB, sRGB, MyWonderful RGB? Lab colorspace would be

a better starting point. Even then, you may run into its limitations

(<a

turns purple" problem</a>). There is no single way to do what you

want; it may require some experimentation.

Your question is not well defined...

as mentioned in the previous post.. What is you color space.. what is your printer/printer

profile...

then you did not say the software you use...Photoshop? Illustrator, CAD.. and what else?

in PS... make selection, and fill it with a RED.. i.e. FF0000... and print.( do same as for

other primary color).....

but then what kind of RED/GREEN/BLUE you want...? FF0000 or FF0066..? hé..?

in short , you need to calibrate your monitor to match your printer... otherwise you're

right... strawberry red is not as the same as tomato red...

haha :-)

You want to simulate as close as possible the 255RGB combo

purities you see on your monitor.

Soft Proof in your working space of choice with the printer profile

loaded set to Relative Intent. Use Paper White and Black ink to

get you closer if need be.

Then select those swatches and individually edit the color with

your tools of choice to get as close as you can which will still not

get you an exact match due to you seeing dayglo type

transmissive lit phosphors on a display as apposed to reflective

lit printer ink on paper.
