The method of adding information to the label.
The environment where the label will be used.
On what surface will the label be attached.
Expected 'life' of the label.
The type of information to be added.

After considering the above points study the definitions of the specifications below to help you chose the correct label for you.

Size

The size of the label largely depends on what you need it for, but bare in mind that barcodes should not fall below a certain size, so you must be aware of how much space they need and of any text/ logos you want on the label.

Face Material

This is literally the material the label is made of and will usually be paper, however there are many synthetic materials such as polyethylene or foil that can be selected. Paper is described by its weight in 'Grams Per Square Meter' (gsm), normally 70, 80 or 90 gsm and, in addition, the surface of the paper may be 'coated' or 'uncoated'. The terms 'Matt', 'Semi Gloss' and 'High Gloss' typically describe these finishes.

Backing Paper

Usually a 'Glassine' material that has the twofold purpose of supporting the labels in a roll and having the properties to allow any label to be removed with ease, regardless of the adhesive types.

Adhesive

In general terms there are two descriptions for adhesives; 'Permanent' or 'Removable'. Both adhesive types are intended to adhere securely to a surface, permanently in one case and in the other to be peeled off when desired. There are many variations of specifically designed adhesives; Opaque, Freezer, High Temperature, Food Grade etc. all with their own properties. Each case will have to be considered separately and advice sought if doubts arise.

Direct Thermal

The 'Direct Thermal' method of printing requires the label stock to be made from specially treated paper which is activated by the direct application of heat (a fax machine operates in this manner). This type of label tends to be used for internal and short-lived requirements as it not only tends to fade but reaction to heat and moisture limits the field of use.

Thermal Transfer

By using conventional label stock, and passing an ink impregnated 'ribbon' between the heat source and the label during production, it is possible to produce a more resilient printed surface than can be achieved with the 'Direct Thermal' method. Also by using selected ribbons different colours of print may be achieved.

Supplied On

Most label types will be supplied on sheets or rolls. Sheets are an ideal choice for hand applied labels where economical delivery charges and storage space are of importance. Sheet labels can only be supplied on certain sizes (see sizes marked with 's' on order form). For labels supplied on rolls there is additional specifications to be considered.

Direction

This is the direction of the label on the roll, either with the narrow edge of the label leading (Narrow Edge Leading) or the wide edge of the label leading (Wide Edge Leading). Please specify which direction you want the labels on the roll.

Number Across

When dealing with smaller labels it is sometimes possible to have two labels across the roll therefore making storage space easier, and for blank labels that you will overprint yourself you can save half the printing time.
