PP-based plastic sheet ends ‘hit-and-miss nature’ of plastic substrates

Polypropylene manufacturer Megara said Promeg Digital offered printers high resolution graphic reproduction when printing on plastic.

The substrate requires no primer before printing and offers better ink adhesion and colour reproduction on both sides than other plastics, according to Megara.

Bearprint Screenprinting owner Gavin Whyburn said: "We were sceptical Promeg Digital didn’t need to be primed first so we set up a split test. You couldn’t tell which sheet had been primed and which one hadn’t. The image looked great on both."

Craftech digital and prototype manager Allan Bicknell said Promeg Digital had performed well when put through the firm's three Océ Arizona flatbeds.

Megara said Promeg Digital had also achieved positive results on Teckwin TeckStorm, Vutek Superwide and HP Scitex printers, and been praised by Colourchiefs, The Printcentre, Look Print, Peak Digital, Evolution Plastics, John’s Print Centre and Vivad.

"Until now, inconsistent ink adhesion, higher spoil quantities and the need to prime-coat polypropylene have led to increased production costs and quality issues for print companies whenever they printed on plastic substrates," said Megara.

"Digital printers were clearly frustrated with the hit-and-miss nature of other plastic sheet substrates on offer.

"It took our R&D department several years of hard work to develop but we think we’ve found the perfect mix."
