Preparing Work for Print

Consider colour- CMYK over RGB

C- Cyan

M- Magenta

Y- Yellow

K- Key (black)

Subtractive colour, ink on paper

RGB- additive colour, light via monitor projector etc

Offset Lithography most likely to be used in commercial/large prints

Digital Printing

Screen Printing

Use of colour when working in software- Illustrator/Photoshop extra. CMYK is used to define pour as it is when created during the printing process. 

We need to think of colour as ink. (Ha, that rhymes)

Registration Colour- used in printers marks.

CMYK Colours

Creating a swatch/CMYK colour.

Pick colours then use 'add used colours' to make swatches out of all the colours used in a design.

Using tints- how to use the same CMYK value colour at a different percentage to increase the usability of a colour.

Colour Books- different colour libraries that can be used by different printers though the most common is CMYK uncoated. 

Process colours

A process colour is printed using a combination of the fur process inks: C, M, Y, K. By default, Illustrator creates new swatches as process colours.

Global Swatches

S global colour is automatically updated throughout your artwork when you edit it. All spot colours are global; however, process colours can be either global or local, You can identify global colours swatches by the global colour icon (when the panel is in list view) or a triangle by the lower corner (when the panel is in thumbnail view)

Spot Colours

A spot colour is an ink that is used instead of, or in addition to, CMYK process inks. You can identify spot colour swatches by the spot colour icon (when the panel is in list view) r a dot in the lower corner (when the panel is in thumbnail view)
