Glassine
this is the most commonly used Liner for both paper and filmic face materials.

Grain of the board
Machine manufactured board is made up of many fibres, which in general, tend to line up in one direction due to the nature of the process. This produces a preferred direction or grain along which it is easier to fold, bend or tear the board.

Four colour process
Full colour printing using four constituent colours: Cyan, Yellow, Magenta and Black.

Drip Off Matt/Gloss
A printing finish that provides a spot-gloss finish and textured matt effect with very high levels of detail. This process uses standard inks and a special print varnish that allows the application of gloss varnish via a plate followed by a matt varnish. This creates a reticulation effect.

Die-cut
A process that uses a metal die to shear through low-strength materials such as cardboard, plastic, foil and other lightweight materials.

Deboss
Image pressed into board so it lies below the typical “viewing” surface.

Cut and Crease
A process using a die form that includes cutting the printed materials into the desired shape, as well as creasing them to provide accurate fold lines.

Cyrel
A raised image polymer plate. It provides a positive image. Used for pattern varnishes in either UV or Water- based varnishes.

Creasing Process
A process using a die creates creases in the packaging material so that it can fold with ease and without creating any cracking or splitting of the sheet.

Concorra
The Concorra Process is a technique that is used in the cut and crease process to create a superior visual effect to perforation and create an easy-open feature. Partial cuts are offset on either side of the carton to form an easy open tear strip. It provides cleaner tear than perforations.

Corner Radius
radius dimension of the corners of the label. The normal radius used is 1.5mm / 2mm.

Composite Sheet
There are two types of composite sheet the most common is where two or more products from one customers range are printed on the same sheet. This can provide good cost savings, but has to be carefully managed to prevent mixed product. The second type is where two or more components of a job (for example a lid and a base) are both produced on the same sheet.

Coater
Part of a litho printing press which applies coatings to printed board.

Bleed
Printing where the colour continues right up to the edge of the board.

Board Grain Direction
The orientation of the fibres in the structure of the carton board. The direction of the grain usually runs opposite to the major creases on the carton and can be determined by checking the resistance of the board by bending it. The direction that gives the least resistance is the direction the grain is running.

Blanket
In offset litho printing, a rubber surfaced fabric that is clamped around a cylinder on a litho press, to which the image is transferred from the plate and from which it is transferred to the board.
