Rainbow printing – A special security printing technique in which two or more inks are applied on one printing plate.
Gilding – The process of applying a metallic foil as a decorative element. Silver or gold foil are sometimes applied to the outer edges of books or business cards to conjure up luxury and elegance.
Lead paragraph – A short paragraph set in a larger font size or different typeface that opens an article. It gives readers a quick summary of the story and provides a hook to entice further reading.
Acid-free paper – Paper containing no acidity or acid producing chemicals. Acid-free paper degrades less over time than acidic papers.
Slug – In layout applications such as Adobe InDesign the slug is an area outside of the trim and bleed area that can be used by the designer to add comments or other information related to the publication. It is not visible in the final printed pieces since it disappears when the document is trimmed to its final size.
DFE – Abbreviation of Digital Front End, a sophisticated workflow system capable of rendering data for output on a digital printer or press while also handling additional tasks like imposition or variable data processing. The EFI Fiery is a popular DFE.
Scratch off printing – the process of applying a foil to specific areas of a document. The foil can be removed with the edge of a coin or a fingernail to reveal the information printed beneath it. The process is often used on giveaway and contest printed materials, such as lottery tickets.
Short grain web press – A web press that uses printing plates whose long dimension is along the cylinders.
Ghost bar – A ghost bar of take-off bar is a rectangular solid line or pattern that is added to a press sheet and trimmed away after printing. It helps equalize ink laydown on the sheet by extending and evening out the printed area, thus avoiding ink starvation in any one place.
