Inkjet Printing technology: Overcoming the limitations

Inkjet print technology, which was initially developed for addressing, coding and lottery applications, has had substantial growth during its 40-year history. The immediate and ongoing appeal of Inkjet technology has been its water-based ink. As many inkjet inks used no volatile organic compounds (VOCs) or hydrocarbon based solvents, they were also embraced for their environmental advantages.

The Advantages of Digital Production

As an evolved digital device, inkjet presses today enable personalized or variable data print (VDP), which has been a boon to print industry segments such as direct mail.

Compared to offset, digital inkjet printing technology produces far less page weight. For example, inkjet adds about one fifth of the weight of offset printing to an A4 page after drying. The reduced weight has had a significant impact on expense, in terms of shipping costs, mailing, and the price of ink removal for recycling.

Inkjet printing technology Limitations

Inkjet printing, which involves a direct-to-media ink application, requires that the media be pretreated with a special coating to assure sufficient ink-to-substrate adherence. A limited range of supported media types and B2 (29 in.) / B3 (20 in.) -only formats on inkjet also constrains its application range and profit potential for print providers.

In fact, since the dawn of production digital print providers have clamored for B1 (41 in.) media support.

Landa Nanographic Printing® Technology vs. Inkjet Printing Technology

Unlike production inkjet printing, Landa Nanographic Printing® Presses support B1 (41in. / 1,050 mm) format substrates. It also prints on a virtually limitless range of substrates, including lower-cost, off-the-shelf substrates similar in breadth to offset printing.

In the Landa Nanographic Printing® process, the media requires absolutely no pretreatment. The press ejects ink onto a heated blanket. The ink is then transferred to the substrate and creates an ultra-thin film layer. The process also includes immediate drying for the media – literally, in seconds – boosting throughput and productivity. Media imprinted in the Nanography® process also doesn’t undergo paper cockling, as can happen with inkjet. Further, the output is ready for finishing immediately – saving valuable production time.

No Special Environment for the Landa S10 Press

In shops running both offset and digital printing, the devices normally operate in different areas and environments. Inkjet press and other digital equipment generally require controlled environments and specially trained press operators.

The Landa S10 Nanographic Printing® Press demands no special operating environment. On production floors, it can be placed side-by-side with offset presses. It also uses the same broad range of substrates as offset presses, as well as the same operators who, by the way, require minimal, specialized training.

Defining the New Digital

Similar to all digital print devices, the Landa S10 press needs no printing plates and related chemistries. It thus reduces set up and make-ready times and eliminates start up press waste. The press delivers print on demand production, affordable short runs, and personalized print applications, as well as reduced finished media weight and freight costs compared to offset.

With no substrate pretreatment, B1 (41 in.) off-the-shelf media support and instant drying capabilities, the Landa Nanographic Printing® process separates itself from other digital printing technologies, including inkjet.
