Different ways to create swatches:
Different kinds of swatches:
Normal Swatch:
Global swatches:
When changing the colour of a global swatch it will automatically affect every piece of work using this colour. It will change the colour immediately.
When using global colours, the colour pop-out changes to choosing the tone instead of another colour.
Spot Colour
- Colour printed not using a mixture of CMYK. Colour that is printed with it's own ink.
- Spot colours can make print jobs cheaper
- Creates consistently
- Can print colours that aren't possible using CMYK - e.g. metallic & florescent
- Unique reference number - uses pigments to mix and create the colour
Click on pantone swatch to add it to the swatch list.
This colour reference only works in commercial print because the colours in Inkjet printers are made from CMYK, not spot colours.- Halftone - makes it possible to print different tints of one colour at the same time
- Used when screen printing with tones and tints.
Saving swatches:
ASE
Enables you to open it in any adobe software program
Save this is the same project folder so it is easy to find when trying to access it on another program

During this final workshop we were given an InDesign document and told there are 8 errors and problems to solve in it. We were put into groups of three to do this. I was with Charlie and Jane. We managed to find all 8 quite quickly.
The Document
1. Spot Colour
The document is only allowed to have 5 inks (CMYK and a Spot Colour), however there are 2 extra spot colours which are not being used.
2. Bleed Lines
The background colour of the first page does not extend to the Bleed Line.
3. Image Link
The image to the Illustrator File has a missing link.
4. Background Colour
The Background Colour being used is an RGB Colour Mode. The document requires CMYK as it is for print.
5. Image Size
The Image being used is the incorrect size for the size of the frame. It has been resized in InDesign to 15% of its original size therefore changing the dpi and making the file size much bigger than it should be.
6. Colour Mode
The Colour Mode for the 3rd Bird is incorrect for Print as it is using RGB. It must be CMYK.
7. Image resolution
The resolution that has been used for the image is 72dpi which is incorrect for Print.
8. Registration Inks
The amount of ink being used is over 300% so the Ink Limit has been exceeded. This is due to the designer using Registration Ink which has all ink colours within it.
After this we were given a quick talk on 'pre flighting', which is the set up checks which are done to a document before it is sent to print.
