Prints on anything
NanoInk overviewIn the course of a decade of research into nanotechnology, Landa discovered that ink pigments, when reduced to nanometric scale, become unusually powerful colorants. Nanopigment-based Landa NanoInk™ Colorants are at the core of the Landa Nanographic Printing™ Process.
How Big is Nano?
- One nanometer is one billionth of a meter.
- A human hair is about 100,000 nanometers wide.
- The smallest things seeable with the naked eye are 10,000 nanometers in size.
- Landa NanoInk pigment particles measure just tens of nanometers in size. In comparison, good quality offset inks have a typical particle size of approximately 500 nanometers – ten times larger.
With Landa NanoInk™, the Results are Bigger Than You Think
The ultra-small Landa NanoInk Pigments are extremely powerful absorbers of light. This enables unprecedented image qualities such as color purity, edge sharpness, high image density and uniformity. With these capabilities, Nanographic Printing technology produces ultra-sharp dots of extremely high uniformity.
In comparison, inkjet-printed dots are characterized by poorly defined edges. This effect is due to the capillarity of the aqueous ink that causes it to be absorbed and wicked along the paper fibers. Offset printed dots are sharper than inkjet, but also suffer from edge raggedness due to ink capillarity.
Broadest CMYK Color Gamut
The Landa Nanographic Printing™ process breaks through yet another barrier. Because the Landa NanoInk pigments are extremely small, the light dynamic range achieved by the Landa NanoInk formulation in the Nanographic Printing process is wider than any other printing processes and covers more Pantone colors than offset printing. This translates into bigger effective gray levels. Additionally, Nanography and Landa NanoInk create printed solid areas with lightness depth (density) values incomparable to any other printing process technology.
Thin, Dry Ink. No More Paper Cockling.
Landa NanoInk Droplets are ejected with precision timing onto a heated transfer blanket. While on the heated blanket they spread and quickly lose their water content. The dried ink dots are able to form a very thin layer of ink that is just 500 nm thick. This thin layer is transferred as a dry polymeric film onto the substrate where it literally laminates the paper surface without penetrating the fibers.
Gloss, Uniformity and Roundness
The thin dry layer of Landa NanoInk permits precise and extremely efficient low ink laydown. This accounts for the ability of the Nanographic Printing™ technology to match the gloss of the paper and to produce dots with super-sharp edges and high optical uniformity. As a result, dots obtained using the Landa Nanographic Printing™ Process are exceptionally round.
Fast, Steadfast Printing, on Anything
Dry ink transfer benefits include digital printing at very high speed on ordinary untreated coated or uncoated paper and practically any plastic packaging film or label stock, and the creation of abrasion- and scratch-resistant images that allow immediate finishing right off the press.
Up to 8 Colors, All of Them Green!
Landa NanoInk is water-based. This means it is less costly than any solvent- or UV-based ink and it is also naturally eco friendly.
