Exingo,
Photoshop will create the two-color separations …..What does this
mean?<<
With Litho printing, each colour is applied separately. Each colour requires a printing plate that is inked with the particulat ink. You are referring to ‘Duotones’ that consist of two Spot colours. These, when separated, will result in two pages, each carrying the data for one colour. These are ‘printed’ upon ‘lith film’ which is used to produce the individual printing plates.
