OUGD504: Design Production - What Is Design For Print? Creative Suite Workshop: Illustrator

Colour Modes

CYMK

• Also known as Process Colour
• Talking about inks 
• CMYK are the ink used in the process
• Subtractive colour, all the colours mixed together makes black
• For Full colour printing job - piece of paper goes through four times
• Lightest colour is printed first - Yellow then Cyan then Magenta and finally Key (or Black)

RGB

• Additive colour, all the colours mixed together makes white

Application of colour in Illustrator

Menu > Select all unused swatches > delete

 

- Registration swatch, should only be used for registration marks

- To create a new swatch, can alter the CYMK values to create a new swatch

- To create a swatch based on artwork, can use the 'eye drop' tool to select the colour

- Menu > Add all used colours

- Add colour swatches from art work in the document

- Global swatches have a link between the swatch and the artwork which that swatch has been applied to

- With local swatches there is no link between the swatch and the artwork that the swatch has been applied to

- With global swatches you can work with tints of that swatch

Menu > Create new swatch

- Series of tints for one swatch 

- By editing the 100 % swatch all of the tints for that swatch will be affected as they are all linked

Spot Colour 

• a colour that is printed not by mixing CMYK
• It is a ready mixed ink
• It is cheaper as it is just one ink and one run through the printer
• Could create expense if spot colours are added to the CMYK print
• Consistent application of colour - Will always be the same colour
• More exciting colours - Colours that aren't possible to reproduce using CMYK inks
• Accessed through Pantone colour libraries 

Process Colour  

• The process of mixing and layering CMYK
