Glossary of terms

SHRINK WRAPPING

Method of packing printed products by surrounding them with a thin plastic film which is then shrunk by heat to form a taut protective covering.

SPECIAL COLOUR

This is a colour that is specially mixed rather than printed from CMYK and is listed in a Pantone colour swatch book. For example, if a logo contains a special blue and is used alongside CMYK, this is termed a five-colour job.

SPINE OR BINDING EDGE

The side of a printed document on which any binding is applied or the folded edge on an unbound item opposite the foredge.

SPIRAL BINDING

Method of binding loose leaves (most commonly used for notepads) where a single strand of wire is passed through holes punched on the binding edge of the leaves in a spiral. Should not be confused with wire-o binding.

STAB STITCHING

A method of binding where collated single leaves are held together with wire stitches punched through from the front and back close to the spine. Stitches can be hidden by either glueing a separate cover around the spine, or affixing binding tape.

THREAD SEWING

Generic term for number of different binding styles in which the sections of a book are held together by threads which are looped through holes punched on the binding edge of the printed sections.

TYPO

UNCOATED PAPER

Plain paper which has no coating.

UV VARNISH

A varnish that has undergone an accelerated drying process using Ultra Violet light which is applied to printed matter. When applied to specific areas of a sheet it is termed a spot uv varnish.

VARNISHES

Special varnishes applied to printed matter to protect literature from ink smudging or finger marking, or to enhance appearance. There are four main types sealer, gloss, matt and UV. Varnishes are commonly used on matt or silk coated paper, as these types are more prone to smudging than gloss coated paper. Varnish applied to a specific area of a document is known as spot varnish and when it is applied to the whole document it is termed as an overall varnish (or less commonly as a flood varnish). The difference between a varnish and a coating is that varnishes take longer to dry.

VISUAL

A preliminary layout of a document indicating the general design and the position of the various elements.

WEB FED PRESS

Presses, which are fed by paper from a reel as distinct from separate sheets. They are normally used for low quality, high run work.

WET PROOFS

Colour proofs produced using the same printing plates, paper and ink that will be used to print the final job.

WIRE-O BINDING

Method of binding loose leaves where a pre-formed double strand of wire is looped through holes punched on the binding edge of the leaves and then clenched to form a closed circle. Not to be confused with spiral binding.
