The full impact of inkjet print technology has not yet been seen in the label and packaging market, and still the core technology continues to evolve at breakneck speeds.
Early developments aside, the breakthroughs occurred with innovations in “re-circulating ink systems” and “small multi-level drops.” This in combination with increased nozzle density and ink improvements has led to reliable high speed, high resolution, single pass digital label presses. The first generation of machines satisfied the market’s demand for flexibility; the second quickly followed with improvements in image quality.
Each successive generation of machines shows yet higher performance and more integration to a digital workflow, with each generation building on developments in the core inkjet technologies. We are now starting to see direct to object printing which – when fully implemented – will revolutionize the production process.
It is not just printheads and ink. Software, electronics, chemistry and integration know-how continue to drive this trend, ultimately leading to a digital production process that will challenge the conventional product marketing.
Thankfully it is not just labels and packaging that are fueling the core technology. Inkjet technology is widely used in the production of ceramic tiles, textiles, display graphics, newspapers and transactional mailing. Inkjet has proven itself in large-scale industrial applications.
Challenges continue to be addressed and we see breakthroughs in many different areas. The ability of digital print to produce short runs as economical as long runs and even 100% variable data, means the volume of images increases exponentially. This issue is being addressed by software using hardware acceleration, by specialist screening technologies that enhance image quality. Meanwhile, low migration inks and new colorants address some of the specific application requirements.
As technology enables a new print process, we see a different challenge facing the printer. What is the impact on their business? How will they re-engineer their business to take advantage? To address this we first need to understand business today, and what conventional wisdom is challenged by inkjet printing.
With analog printing, a lot of time is spent on the image and pre-press – once correct images can be used many times – re-using or re-making plates and screens and letting the press run. With digital print, several new images can be printed every second, maybe just a different bar code, maybe a selection of images from a database, increasing versatility considerably. Either way, the pre-press becomes an integral part of print and the volume of pre-press work increases.
The printing itself may start with mixing spot colors, but think again for digital. How will the translation of spot colors to process colors be managed? But perhaps the greatest challenge is on press. The analog press requires a highly skilled and experienced pressman to run it, while successive generations of digital inkjet presses will become more push button. The business of tomorrow will not look like the business of today. For those willing to face the challenges and take advantage of the opportunities offered by inkjet, there is a very bright future.

The Inkjet Conference will be held Oct. 7-8, 2015 at the Swissotel Neuss, Düsseldorf, Germany, and will cover every aspect of the core technology is addressed. The focus is on printheads, inks, software, curing and drying and the chemistry.
