Digital Print Workshop

We've got a workshop about how to mange colours in commercial printed.

There're 3 way on commercial print : Offset Lithography, digital printing and screen printing (not really used).

Main colours modes : CMYK (subtractive colour) and RGB (additive colour). For the CMYK one, we need to think of colour as ink (printing process).

When you choose a brighter tint of one of global colours, you can see the percentage.

Spot color

Process colours

A process colour is printed using a combinaison of the four process inks : CMYK. By default, Illustrator creates new swatches as process colours.

Global Swatches

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