- CMYK is the subtractive colour mode
- RGB is the additive colour mode.
- CMYK is process colour, they are the printing ink, the inks used during the printing process.
- Black is called the key colour as it reenforces the print, it brings it all together.
To creeat multiple swatches at the same time, you can just make all of the shapes the colur you want them, then go to swatches and settings then add used colours.
- Spot colour is a colour that is a ready mixed ink, therefore CMYK doesn't have to mix it. This makes the process of printing cheaper.
- A CMYK colour needs four colours to print it, where as a spot colour only needs one colour to print, therefore it is much cheaper to print than CMYK.
- Although they can also add an additional expense, for example if you use lot of spot colours or CMYK and spot colours means that it will cost more.
- Spot colour is also good for consistency, if you use a spot colour it will always stay the same, this is good when it comes to branding and identity.
- You can get more exciting colours out of the CMYK range, such as metallic inks, or florescent inks.
This is how you find the pantone libraries.
You should never change the name of a spot colour, if you change the name the printer doesn't know which colour it is to match it successfully, as that was the reference number.
Even if the tint of a colour is different, you would only need to pay for one plate, when printing commercially.
