Q. Can I print in colours?

A. Yes. Most thermal printers have only one ‘printing head’. If you need a colour imprint, you can remove the black ribbon and replace it with a colour ribbon. There are a few printers (known as ‘process colour’ printers) that can print multiple colours and a black bar code simultaneously, but they are more expensive than the traditional desktop unit.

If you’re printing barcodes on labels, use a black ribbon (or dark colour) to ensure that the barcode will be readable.

There is a limited variety of coloured ribbons readily available for most thermal printers; we also offer a colour matching service. We can help you choose the right ribbon for your label material and application – just ask us. (see thermal transfer consumables)

Q. What are the key factors in choosing a thermal transfer ribbon (TTR)?

A. There are several things you need to consider:

Ribbon width: the ribbon should extend past the edge of the label material to prevent the printhead being damaged from abrasion by the label material (e.g., a 70mm wide label requires a 80mm wide ribbon)

Ribbon type: the three types are wax, wax/resin and resin:

• Wax ribbons cost less than the other types and are usually used when long-term durability is not an issue. They are best for printing on coated or uncoated paper tags and labels. Typical uses include shipping labels, pricing labels and other indoor applications.
• Wax/resin ribbons are more expensive, but the imprint is more resistant to scratching, smearing and mild chemicals. They are best for printing on coated paper, coated tags and films and are suitable for short-term outdoor uses.
• Resin ribbons are the most expensive, but the imprint is very durable and resistant to most chemicals. They are best for printing on synthetics materials such as polyester and polymide.

Ink configuration: when you buy ribbon you need to specify the brand of printer to ensure that the ribbons are wound in the correct configuration – ink side wound ‘in’ or ink side wound ‘out’.

Printer core diameter: you need to ensure that the ribbon is designed for the inside core diameter of your printer brand, because some cores have special slots that fit in the ribbon feed mechanism.

Roll length: This equates to maximum roll diameter. All printers have a maximum roll diameter.

Q. What determines the price of ribbon?

A. Ribbon price varies according the ribbon type, size, volume and colour:

Type: this is determined by your application

• wax: most common, lowest cost, used on uncoated paper labels and tags
• wax/resin: more expensive, usually used on coated paper and coated tags
• resin: highest cost, used on polyester labels and tags for maximum durability

Size: ribbon rolls with more square metres of material (width x length) cost proportionally more than ribbons with fewer square metres of material

Volume: price can depends on the volume being bought (e.g., when group deals are offered)

Colour: black is always the lowest price, and colours are more expensive
