The Evolution Of Digital Printing Technology: Advances In Digital Imaging

Digital Printing 

The digital printing revolution began in the 1970s with the development of non-impact dot matrix and inkjet printers for desktop use. These printers utilized early digital imaging technologies to rapidly and efficiently output text and basic graphics. Initially the quality was poor compared to traditional printing methods. However, steady improvements were made to the printheads and inks which increased resolution and allowed for more complex color reproduction. By the 1990s, desktop inkjet printers and color laser printers were commonly found in homes and offices around the world. These provided an affordable way for individuals and small businesses to produce short-run color documents internally.

Improvements in Resolution and Speed

As Digital Printing  moved beyond the desktop, greater investments were made in R&D to develop higher-performance systems. Continuous improvements have been made to printing consumables like printheads, inks, and toners which has allowed for finer resolution and faster printing speeds. In wide-format and commercial applications, drop-on-demand piezoelectric and thermal inkjet technologies were primarily utilized which allowed for photo-quality color output on various substrates up to 13” wide. The development of LED arrays also improved addressing and firing individual nozzles for increased image quality. Print speeds increased to over 100 feet per minute while maintaining resolutions up to 1200 dpi or higher.

Emergence of Digital Presses

In the early 2000s, the first commercial digital presses were introduced bringing full-color, multi-page printing capabilities previously only available through offset lithography within reach of general commercial printers. These presses incorporated xerography, inkjet, and toner fusion technologies to output single pages or booklets on cut-sheet paper or rolls. Resolution and speeds continued increasing to rival offset capabilities while allowing for true variable data, on-demand runs, and versioning capabilities only possible digitally. This enabled new applications and business models centered around personalization and one-to-one By 2010, a wide range of mid-volume cut-sheet and continuous feed digital presses were available capable of processing tens of thousands of pages per hour.

New Substrates and Applications

As digital printing technologies matured, their capabilities expanded beyond traditional paper substrates. Wide-format inkjet saw the rise of printing directly onto rigid materials like corrugated cardboard, wood, glass, metal, and plastics. This opened opportunities in signage, displays, decorative surfaces, and industrial marking/coding. Meanwhile, advances in toner and ink formulations allowed for textile printing directly onto fabrics. Water-based dye sublimation inks enabled soft signage, apparel, and home decor printed on materials like cotton, polyester, and mixed fibers. New application spaces emerged in clothing, home furnishings, and functional printed electronics. These applications require different substrates and finishing steps compared to conventional paper printing workflows.

Growth of On-Demand and Short-Run

With the proliferation of digital presses, an abundance of niche commercial printers emerged specializing in short-run, variable data, and on-demand print applications. Digital technologies enabled much lower entry costs compared to offset while providing the flexibility and quick turnaround times customers demand. This empowered small businesses, agencies, publishers and designers to produce one-off collateral, catalogs, books, and customized direct mail pieces on an as-needed basis without large inventory requirements or change fees. Transpromo, photo books, and customized packaging grew to be large application segments for digital printing. Short-run capabilities also opened opportunities in publishing, particularly for literary fiction, children's books, education materials, and professional/specialty titles.

Workflow Automation and Personalization

To support an ever more complex on-demand printing landscape, new management systems are required. Automated document and prepress workflows streamline file preparation, variable data merging, versioning, and personalized content assembly from databases. Integrated approval processes coordinate proofs and approvals between clients, designers, and printers. Beyond personalization at the individual record level, dynamic communications systems allow for A/B split testing, multi-channel distribution, and real-time based on customer behavior and analytics. As data-driven evolves, it demands tighter integration between creative services, print production, fulfillment, and multi-touch brand communications. New platforms facilitate these closed-loop, analytics-based workflows across departments and partners.

The Transition to Digital is Complete

Over the past few decades, digital printing has evolved from a novelty desktop technology into the mainstream production solution for commercial, packaging, and in-plant printing applications. Its short-run, on-demand capabilities have become table stakes in today’sand publishing landscapes. As innovations in imaging technology, substrates, and integrated software solutions continue, digital’s versatility makes it increasingly suitable to disrupt more traditional printing segments. Meanwhile, hybrid workflows combining elements of both digital and traditional printing are allowing printers to gain efficiencies and produce the optimal mix of short, medium, and long print runs. For the majority of commercial and in-plant printing needs, the transition to a primarily digital model is now largely complete.
