In an industry where there’s no room for compromise to ensure CMYK and spot colours print exactly as required, packaging print specialists can rely on GMG DotProof and GMG OpenColor.
This is the opinion of John Panton (technical director of Digital Distributors and CEO of the newly-formed Colorflow Solutions group). ‘We recently implemented world-leading colour management solutions from GMG at Polyflex, a company known as a specialist in packaging graphics. These included GMG’s OpenColor technology,’ John explains. ‘Packaging proofing and predictability of output is hugely challenging owing to the myriad print technologies, substrates and print conditions that may be used on a single brand. This requires reference printing or profiles for all these outputs, something that’s simply not being done today in the face of technology challenges,’ John maintains.
Among these challenges and common reasons for poorly representative proofs, John cites printers having insufficient space to include reference colour charts for profiling; and the prohibitive cost and time constraints of profiling.
‘And,’ he says, ‘as it’s not always straightforward CMYK printing, separations and colours are constantly changing. It’s challenging to accurately predict the overprint behaviour of spot colours. Additionally, standardised reference printing profiles simply don’t exist for all packaging; and reference printing conditions are used that aren’t appropriate for a particular product’s printing process.’ John continues: ‘Let’s consider flexographic printing where the anilox rollers, plates and substrates all play a significant role in output colour, while the combination of colours overprinting one another is endless. CMYKOG, CMYKOGV, CMYK + Pantone.
185C, Pantone 185C,Y,K, etc. One simply can’t build a single profile for all these combinations. In addition, there’s insufficient space on the press sheet for all the required patches. Profiling of just some combinations for a specific brand or product would take days. This is where GMG OpenColor provides an answer.’ Using GMG OpenColor, profiles can be created from a limited number of colour patches. These are not limited to CMYK, but can extend to seven or more separations. Thanks to OpenColor’s database structure, previously sampled data, as well as characteristics of anilox rollers can be used to update, change or create a reference profile in minutes before making a new proof, dramatically reducing or eliminating the need for dedicated press runs. Polyflex has a proud reputation of delivering quality service and innovation to its customers. Apart from head office in Durban and regional offices in Gauteng and Western Cape Town, Polyflex is present in five other African countries including Mauritius. Polyflex head of operations, Stuart Baylis, takes up the story. ‘We are working with some of the world’s leading brands, many of which already use GMG technology. When GMG introduced its OpenColor program, we simply had to take a serious look. It answers the particular needs of today’s packaging market. Aligning our proofs to our plates speeds up and simplifies the approval process. Brand owners no longer need to spend valuable time on press-side approvals.’
Polyflex has had a long-standing relationship with Digital Distributors. Says John Panton: ‘We have partnered with Polyflex for a number of years, supplying technology, services, consulting and training. This organisation is extremely professional, which places a fair demand on suppliers. We have enjoyed a relationship of mutual respect and have always found Polyflex to be a highly professional and innovative
team. We are proud to continue playing a role in their success and working alongside them to further grow the success of GMG in their organisation,’ John concludes.
