Artwork Design which is used for printing. This can either be hard artwork (printed art), or digital artwork (artwork which is a computer graphic file).   Backing Refers to the carrier sheet of a material which is peeled form the label & disposed of. It is the opposite to the face material.   Bleed The area on the artwork which extends past the crop marks. It is important that artwork be set up with bleed for printing purposes.   Butt Cut Labels Labels which are separated by a single knife cut. Usually used on rectangular labels.   CMYK Stands for cyan, magenta, yellow & black. These colours are used in four colour process printing & is ideal for artwork where the effect of many colours is required such as photo reproduction.   Colour Separation The process of separating coloured artwork into either cyan, yellow, magenta & black (CMYK), spot colours or a combination of both.   Corner Radius The curve of the die blades to make a rounded corner on a label. RG Printed Labels usually uses 2.5mm corner radius as its standard but any corner radius can be used.   Crop-Marks Marks made on artwork which show where the label is to be cut or cropped.   Die Tool used for cutting the label shape. This only cuts the face material & not the backing so the label can be peeled away easily.   Die Cut To cut labels with a die to the correct size & shape.   Embossing Process of using a die or dies to create an impression on the surface of the label, giving it a raised look & feel.   Face Material Any paper, fabric, laminate or foil suitable for printing on. This is the part of the stock which is printed & is adhered to the backing.   Film The material whish is used to create negatives, with one side coated with emulsion. When exposed to light, the image is transferred to the film & then is developed in chemicals.   Foil Stamping The application of heat and pressure to a stamping foil to transfer it to the face material.   Four Colour Process A printing process which uses cyan, magenta, yellow & black to create all colours usings halftones.   Halftone An image made up of different coloured and sized dots, which when combined give the illusion of a graduation of colours.   Lamination A protective plastic film adhered to the label which also gives it a gloss or matt look & feel.   Negative An image which has been reversed. ie. Light areas are now dark & vice versa.   Overprinting Printing process which is carried out after the initial printing. May be used where consecutive numbering or barcoding is required on labels.   Permanent Adhesive An adhesive which has a high adhesion to a variety of surfaces.   PMS Swatch Stands for Pantone Matching System. A worldwide recognised colour system. The most common are coated & uncoated.   Quiet Area The area around a barcode which needs to be left white in order for the barcode to be read correctly.   Register Marks Marks used around the outside of artwork, which assist in the lining up of each printed colour.   Removable Adhesive An adhesive which has a low adhesion to a variety of surfaces.   Rolling Direction The direction which label is facing when it comes off of a roll. There are eight alternative roll directions.   Spot Colour Colour used other than CMYK. Usually a PMS colour.   Spot Varnish A varnish which is applied to the label in certain areas. This may be used as an effect or if a quiet area is required for a barcode or overprinting.   Sprocket Punched Round or rectangular holes punched into the label stock. Often used for dot matrix printers, pin wheel machines, etc.   Trapping Process used prior to outputting film where colours slightly overlap each other. This is so when the image is printed there is no space between colours where there should not be due to the stock shifting slightly between different colours being applied.   Trim Marks See crop marks.   Varnish A thin, clear coating printed over the top of the coloured print for protection.   Web Direction The direction which the material travels through the printing press.
