The London-based printer produced point-of-sale advertising for Tesco’s Finest range that "twinkled" as customers walked past.

Augustus Martin’s ‘disruptive’ effect is created using a combination of traditional printing processes and inks manufactured by the firm.

Director of stores marketing at Tesco Andrew Miles said: "The POS was really noticeable and clearly defined the premium values of the Finest range. This promotion has been really powerful and allowed our Finest brand to be clearly visible throughout the Christmas period."

The process was used on more than 500,000 individual POS elements across shelves, ceilings and store entrances.

Augustus Martin group sales director Daniel Pattison said: "The Finest promotion uses one of our new disruptive production techniques, which actively engages shoppers, giving brands and retailers an opportunity to add real impact to their POS."
