CMYK
Definition: CMYK mode is used to define colour as it is when created during the print process. This can also be referred to as Process Colour.
Printing: There is a transparency with Cyan, Yellow and Magenta. This means that when the colours print and overlap(K), different colours are made in the print process.
Cyan is firstly printed, with yellow then printed. On top of this magenta is then printed which is when the colours begin to come through. The application of Key (black) brings the colours together and provides well defined shadows within the print.
- as CMYK requires 4 inks, this makes the printing more expensive
Spot Colour
Definition: a colour that is printed with the application of one ink.
Example: Pantone reference system
- Spot colour is much cheaper to use as only one ink is used. This also makes it more efficient as only one plate is used. This is something to consider when producing the publication as it will be more cost effective to produce which is important if the publication will be distributed for free
- Using a limited colour palette would also mean that printing would be cheaper as less inks are used.
- The swatch palette must be used to be able to use spot colours
- Using spot colours allows you to print colours that you are not able to create with CMYK
- Spot colours are used in screen printing
