All language subtitles for 1. What is RGB & CMYK

Hi there, in this video we're going to
talk about RGB versus CMYK.

You might have come across this,
you might have not.

It's kind of essential, I guess,
to understand the basics...

so let's cover them quickly.

So when you're setting up
a new document...

you're given the option
to pick RGB or CMYK.

So if I go to 'Print',
and pick one of the defaults...

it's going to--
you might not have this viewable.

You might have to click 'Advanced Options'.

By default it's going to
go to CMYK.

If I go something like Web, or Film, or...

pretty much, any of the other ones,
and I pick one of these...

it's going to default to RGB.

So RGB is a color which is
Red, Green, and Blue.

Basically those are the colors used
for screens to display color.

So my laptop in front of me right now
uses a mixture of Red, Green, and Blue...

to generate the colors that we see...

but we know that if we use our printer,
the one on our desk...

if we have a look...

it's going to use Cyan, Magenta,
Yellow, and Black...

that's CMYK, it uses those colors
to mix together.

The big difference is,
RGB has a secret ingredient...

it has light, luminescence.

It has light coming out of the screen...

that allows it to generate more colors
than CMYK can.

You'd probably have tried it before...

you've printed an image
that looked great on screen...

but the print's a bit washed out...

because your screen has light
coming out of it...

whereas the paper from your printer
has no lights.

So it's a different kind of color mode.

RGB is a bigger gamut of color,
CMYK is a smaller one.

Now why would you use both?

Basically RGB, as a rule...

is probably your best one to use
for everything at the moment.

Especially if you're going
to use something...

that's going out via email, or via website.

Even if it's going to print,
it's probably going to be dual use...

so many things, are these days...

you'd probably going to
want to use it for both...

your website, to be downloaded,
and to be going to commercial print.

If it's something you're creating...

like a postcard that's going
to commercial print only...

you might want to consider using CMYK...

but in that case as well,
my experience is that...

most modern printers will expect RGB.

They've got some cool reps and ways
of kind of...

making, I guess, getting the most
out of their CMYK.

So often, just use RGB,
it's going to be your--

if you're unsure, just use RGB.

If you're a little bit more professional,
you probably know this already then.

And you can use CMYK.

Now, let's have a little look
at the differences between the two.

Let's go to 'File', 'Open'.

In here there's one called 'Colors.ai',
open that up.

So this my RGB document,
how do I know?

The easiest way, up in the tab here,
you can see, it's RGB.

The way to change it, let's say
I want to be in CMYK...

I can go to 'File', there's one called
'Document Color Mode'.

You can see, I've ticked RGB.

Watch what happens when
I change to CMYK.

Watch the colors, watching the colors.

They wash out quite a bit.

It's giving you representation now
of what it would look like in CMYK.

Now if you're only going
to commercial print...

and they've asked for CMYK...

there's no point being in RGB...

but if you're like me...

I often dual use things, I'll use it
for all sorts of things.

I'll start in RGB, and often
just send it to the printer in RGB...

and depending on your printer...

they've got really good ways
of converting it to CMYK...

to try and restore some of those colors.

I hope that's giving you a little bit
of understanding of CMYK and RGB.

So the rules are, my basic
kind of rules are, use RGB...

and send it around, it works fine.

It works on digital, and works good
for printing to local kind of printers.

Even my office printer accepts
in RGB better, and processes it nicer...

than if I send them a proper
CMYK official version.

But you need to know
the difference between the two.

Some printers will demand CMYK,
and that's fine, that's the way they work.

So just make sure you're working in CMYK.

You might have to have
two versions of the document...

one in RGB for digital...

and another one in CMYK.

All right, let's get into some more
exciting stuff about color.

Let's get into the next video.
