Getting Thermal Ribbons Right for Delta Sound Surrey

Getting the correct thermal ribbons for your printer depends on the material being printed as well as the thermal printer being used.

Case Study Client: Delta Sound Surrey
Sector: Musical equipment hire
Challenge: Print rubbing off rental equipment labels
Solution: Correct thermal ribbon specification for acetate substrates
Result: Clean, durable print — and an ongoing supply relationship

The Client

Delta Sound Surrey hires sound equipment to the music industry. Their inventory spans professional audio gear used at venues, events, and recording sessions across the UK. Every item needs clear, accurate identification — rental terms, asset numbers, and contact details all printed on labels that stay legible through handling, transport, and the wear that comes with regular use.

Like many hire businesses, Delta had a simple labelling requirement. What they didn’t expect was that their labels would become a recurring problem.

The Challenge

Delta were using acetate labels with rental information printed directly onto them using a thermal transfer printer. On paper, the setup worked. In practice, the print was rubbing off every time equipment changed hands.

The labels looked fine when applied. But after a short period of handling — loading into flight cases, being moved between venues, the ordinary rough-and-tumble of hire life — the printed text was degrading. Barcodes smudged. Asset numbers became unreadable. It was costing Delta time and credibility.

They’d tried adjusting print settings. The problem persisted. The root cause wasn’t obvious — until they got the right people to look at it.

The Investigation

Delta sent samples of their labels to Positive ID Labels. Our technicians examined the material and the print quality, and the diagnosis was straightforward: Delta were using the wrong thermal transfer ribbon for their substrate.

This is one of the most common thermal printing errors — and one of the most easily missed. Thermal ribbons come in three main formulations: wax, wax-resin, and resin. Each is engineered for a different family of materials.

• Wax ribbons perform well on standard coated and uncoated papers. They’re the most cost-effective option for everyday paper label applications.
• Wax-resin ribbons offer improved adhesion and print quality on coated papers and light synthetics. They bridge the gap between paper and plastic applications.
• Resin ribbons are the only type that bond reliably to plasticised or synthetic substrates — polypropylene, polyester, acetate, and similar materials. They resist abrasion, chemicals, and heat.

Delta were using a wax ribbon on an acetate label. The ribbon wasn’t bonding properly to the surface. Every time someone picked up a piece of kit, a little more print came with them.

The Solution

We recommended switching to a wax-resin ribbon matched to the acetate substrate. Delta ran tests before committing — sensible practice for any change to production labelling — and the results were clear.

Pete Howells, Technical Director at Positive ID Labels, commented:

“We have supplied thermal ribbon of all sorts to many customers. The colour options available allow for flexible labelling outside of repetitive and boring black. It allows companies to stamp a little more individuality on their labels if they can overprint in white or blue or red — and we can supply these colours quite easily for our customers.”

The right ribbon made an immediate difference. Print adhered cleanly to the acetate surface and held up through normal handling. Delta’s labels were doing their job again.

Colin Wilkie, reflecting on the outcome, said:

“With a combined experience in the labelling industry exceeding 100 years, our team quickly resolved the problem Delta were facing. This is a typical result for the team and one I am very proud of.”

The Outcome

Delta Sound Surrey now receive regular ribbon supplies from Positive ID Labels — matched to their materials, specified correctly from the outset, and backed by the kind of technical knowledge that prevents problems before they happen.

The underlying lesson applies well beyond hire equipment. Ribbon and substrate compatibility matters whether you’re labelling frozen food, chemical containers, or precision components. Getting it wrong is easy. Getting it right is a conversation.
