OUGD504 - Design for Print and Web - Creative Suite session 1

CMYK printing colours

Lighter colours are usually printed first, like cyan or yellow. The inks are clear but when printed on the paper gain their colour. Key is usually printed last.

Tips for using colour - Swatches


In the swatches palette, you can view the name and CMYK numbers of your personal swatches by viewing in 'small list view'


The new swatch button


New swatch palette

Or create a new swatch using the colour palette


To add multiple colours as swatches go to the swatches menu and select 'add used colours'. This adds all colours in the document to the swatches palette.


If you only want to add a few, you can select them all together, then go down to the drop down menu and select 'add selected colours'


The difference between the cut corner and grey box icons in the swatches


And those without



Is that the grey boxed and corner cut swatches are 'global'.



This means that there is a link between the swatch and any object that it's applied to, meaning that the object will update when I edit the swatch. The global checkbox can be unchecked at any time.


Global colours only allow to change the tint of the CMYK colour in the colour palette. We can make swatches from the different swatches:



The name 'process colours' refers to CMYK and the 4 plate printing process.

Spot colour is a pre mixed ink - the colour of it is not made by combining CMYK. Spot colour is used when specific colours are wanted because of expense. The less printing plates you require, the cheaper the job will cost.

Spot colours are also used when metallic, fluorescent or an exclusive colour is needed. To mix a spot colour, either the CMYK numbers or reference number, such as a Pantone number, is used for the printer to reproduce exactly.

To access the Pantone colour library, go to the swatches menu, go to Open Swatch Library then to Colour Books. 


To help finding a colour, either type in the name or the number into the finder box. To display the finder box go onto the drop down menu and check Show Find Field:



NEVER change the name of a colour on the Pantone palette as this will be impossible to reference to the printer.


Spot colours have a spot in a box as opposed to a grey box to show that they are a spot colour.

Your swatch palette is automatically saved to the document you're working on. But what happens if you want to use the swatch palette on a different document? Or on Photoshop? Or InDesign?

Go to the swatch menu and select Save Swatch Library as AI


Like installing a typeface, the swatches palette saved will be consistent on every computer you use.


To use your saved swatches in any document, even new ones, go to the swatches menu, Open Swatch Library, User Defined and it will be there to use!



To have a cross - application swatch library, save as ASE not AI. And save in the same place you keep your images, fonts etc.


 DO NOT SAVE in the Illustrator folder on the computer.


To use different tints of a spot colour is a lot cheaper than using separate spot colours and even cheaper than using CMYK printing plates.
