Process colours
Process colours are printed using a combination of the four process inks: cyan, magenta, yellow and black. By default illustrator creates new swatches as process colours.
Global Swatches:
A global colour is automatically updated throughout your artwork when you edit. All spot colours are global; however colours can be either global or local. You can identify global colour swatches by the global colour icon (when the panel is in view) or a triangle inn the lower corner.(When the panel is in thumbnail view)
Spot colours:
- Registration is used for printing marks
- Colour swatches provide consistency and efficiency to work.
Part 2
Spot colour (spot inks) : alternative model of colour from CMYK
Pantone reference system: Spot colour reference system, each one identified by a unique reference number.
Why do we use spot colours?
- It can be cheaper to use spot colours (CYMK requires 4 printing plates) production of printing press and plates can be expensive in production, more cost effective (if appropriate)
- Spot colours don't need CYMK to be produced.
- Is for consistency in colour reproduction (commercially used) you're then ensured of accuracy.
Access spot colours:
Swatch palette menu - Open colour books
Coated and uncoated: refers to paper stock
Difference between coated and uncoated:
Once we have a reference number, we can type in the number and it limits search results. reference provides accuracy.
Spot colours only work during the offset printing process, there will have to be a conversion.
Pantone + CYMK coated and uncoated, used for reference
Spot colours - 3 inks instead of 4
