Design for Print Terminologies

Colour management
Maintains accuracy of colour reproduction between different equipment and processes in print production.

Gamut
RGB, CMYK and Hexachrome. Desicribes how accuratley particular systems can reproduce certain colours. If you use colours outside the printing gamut it will use the nearest equivelent which may change the overall design.

Colour Profiles
pre defined in relation to specific printing equipment and stock. Differs on Photoshop, Illustrator, InDesign. Different print requirements for each package.

Coated/Uncoated
Provides certain surface quality. can effect how the ink is absorbed.

Process Colour
CMYK - in offset lithography colours are applied using the CMYK gamut applied using half tone dots.

Spot Colour
must be defined is a colour to be printed lies outside the working gamut system. Spot colours must be defined within the image file and in conversation with printers. can be defined using pantone. Pantone colours will not look the same on the screen as they do in print.

Difference between Pantone and CMYK

Lithography
Printing process using plates (one for each colour). ink is applied on the basis that oil and water repel each other. Ink from plates are 'offset' onto a rubber printing surface before being applied to the paper.

Web
Ultra high volume printing (newspaper) often onto huge rolls of paper often use flexograph (relief) or rotogravure (intaglio). much more expensive to set up, cheaper for long runs. less accurate.

Regestration Black
Achieved by printing all four process colours in the same space - used to apply registration marks.

Bleed
'Full Bleed' images must be printed beyond the margin limits to ensure that the white edges dont appear after trimming. standard 3mm.

Tipped-in page
A page that is printed separately but bond along with the other pages. Dofferent formats/Stock

Tip-on Page
Added contents glued onto cover/page, e.g. membership card.

Duplexing
Binding 2 stocks together, acts as 1 page with different colour/stock on each side.

Foil Blocking
Coloured foil is pressed into stock using foil stamp

Title uses gold foil

Embossing/debossing
Embossing refers to raised surface
Debossing refers to indented surface

Die Cutting
Design is cut out of the surface using a metal die

Laminate
Plastic coating, heat sealed onto a stock to provide crisp finish. Splash proof.

Varnish
Colourless coating, applied similar to spot colours.
