CYMK - printing inks
When printed the inks aren't opaque, so when layered they will mix and make a new colour.
Also known as process colours - inks used in commercial print process.
Document set up:
Advaced - color mode = CMYK
Best colour for user interface = grey for colour critical work
How to apply colour:
Colour picker
Colour palette - Editing the colour palette can bring up the CMYK colour picker to mix the colour yourself.
Swatch palette - consistently apply the same colour throughout the artwork
How to work with swatch palette:
- Default swatches always there when opened.
- To delete swatches select them and bin using bin icon
- Folder icon represents colour group
- Registration colour - for trim and crop marks / printer marks
To create a swatch:
First use the colour palette to create the colour you want to use
At the top of the colour palette, click the option menu and select 'create new swatch'
A new menu will come up with the new swatch colour and the CMYK sliders to edit the colour, click OK and it will be added to the swatches palette.
Change the view of the swatch palette by going to options and changing to small list view, this will show the values of each colour and make it easier to identify the colours.
Alternative method:
-Using the colour palette select the colour you want to use and then you can use the eye dropper to select the same colour therefore after.
- From doing this method you can also add these to the swatch palette in a much easier way:
on the swatch palette, use the option menu and select 'add used colours' this will then add all colours used within the artwork to the palette
As you can see the colours have all been added to the swatch palette, with %'s on view too.
Identifying which colours have been added from the artwork have a triangle in the corner of the swatch box and a grey square next to the CMYK box.
- Double clicking the swatch will allow you to edit the colour mixture of the swatch colour.
- With the swatches that have been added from the artwork is a global colour swatch - using this will create a link between the swatch and the object with that colour in, meaning if a global swatch colour is edited any of the objects with that colour will be changed to the new colour.
- When editing a the swatch colours, using a global colour the CMYK colour palette will display it in a tint gradient, whereas a normal swatch will bring up the CMYK slider.
NON GLOBAL SWATCH
GLOBAL SWATCH - when editing these using the tint slider, you can add the new tinted swatch to the swatch palette and it will display with the tint % in the swatch palette.
If you edit the colour of a global swatch which has tints set up as new swatches, it will both the master swatch and all the tints to the new edited colour.
THIS WOULD BE CREATING MONOCHROME ARTWORK
SPOT COLOUR
- A colour which isn't made up of a mix of CMYK. Not printed with process colours ( CMYK ). Ready mixed ink.
- Used for colours which cant be printed from CMYK.
- More cost efficient as will only have to use one colour in printing process.
- More precise in the printing process, if printed in numerous places, the colour would have to be consistent throughout, but if using a spot colour it will be 100% the same.
HOW TO USE SPOT COLOUR
Using a swatch library, you can look through all the colours and choose a specific colour which has a identity number. This will be linked in within the document when sent to a printer.
To use spot colours within illustrator:
Using the option menu on the swatch pallete you can select 'open swatch library' and then select 'colour books'
then select either PANTONE SOLID COATED OR UNCOATED.
Coated or uncoated refer to the stock, if it is an uncoated stock you would uncoated etc
After clicking on the correct colour library it will bring up the full set of colours from that library.
Changing the viewing options to small list, will bring up all the reference numbers for each pantone colour.
To find the colour you want, you can use the FIND menu and search the reference number you want to get the correct colour.
Once found click on the colour and it add it to your swatch palette.
To identify which colour is a pantone colour it will say PANTONE and also have a circular dot inside the box next to the CMYK box.
Again you ca create tints from the Pantone colours in the same way as before and these will work as GLOBAL swatches.
TO SAVE THE SWATCH LIBRARY
Click on option menu and then 'save swatch library as AI'
Re-name the file and then it will save it to the swatches file for Illustrator, you can save it here and it will be easier to open in illustrator or save it to another area with your work.
If saved in the illustrator folder you would open the swatch library using the 'user defined' option and select the lswatch library.
If you saved it to another location you would use the 'other library' option and then locate the file.
To use the swatch library you click on the colour and it will be added to your main swatch library.
If you want to be able to use the swatch library across the adobe suite save it as 'ASE', this will open in any other adobe software.
