Nano pigment printing is a variant of ink-jet inkjet printing using pigments dyed with pigments (powders) with diameters no greater than 100nm (typical solvent and UV inks are colored with powders with diameters of approx. 1000nm or larger).
The use of nano-pigments gives the ink many positive attributes. Nano inks are much slower than conventional inks to consume heads and other components of the printer’s ink system. Such small particles of dye in a natural way, using, among others, nanoparticle attraction stick to the substrate, even if the material was not intended for digital printing.
Thanks to such properties of nano-pigment ink, we can create simple, stable in a trowel printing devices can print on almost any material.
The advantages of nano printing
POSSIBILITY OF PRINTING ON ALMOST ANY MATERIAL
Printing with nano inks allows you to use almost any material as the substrate. It does not matter if the substrate has been redy for digital printing or not. The printout occurs at a low temperature, so the material’s resistance (or lack thereof) to temperature is also not a limitation.
Plotters offered by NANOO allow the use of substrates for printing in the form of a roll or a plates or sheet.
The nano printing technology by NANOO has been tested on several hundred materials used in advertising industry, art and design.
Characteristics of printing on basic groups of substrates in the further part of the description.
VERY HIGH PRINT QUALITY
The use of nanopigmented ink causes the printed image to be perfectly sharp. You can find out by comparing the quality of a drop of ink stuck on paper. In the picture below, a drop from an ink-jet head recorded on paper – from conventional waterbased ink (on the left) and from a nano ink (on the right) Such high accuracy allows obtaining unprecedented print quality and quality of detail reproduction in other technologies.
EXTREMELY HIGH PERFORMANCE
The use of nano-pigments allows very intense ink dye unattainable in any other ink-jet printing technology. Thus, in order to achieve the assumed color effect, the printer need use a smaller amount of ink.
Another factor determining the consumption of inks is its ability to evenly and accurately cover the surface of the printed substrate. Here it turns out that a very thin layer of nano ink covers the surface of the material much better than a thick layer of classic ink-jet ink.
Finally, it gives the result of very low ink consumption by the printing engine. Compared to classic ink-jet printers, ink consumption is 2-4 times smaller. Comparison of the thickness of ink layers needed for proper printing of the substrate is also great when comparing nano printing with other print techniques.
PERFECT SURFACE STRUCTURE AND HIGH PRINT FLEXIBILITY
Prints made in nano technology does not change the surface structure of the material. If you print on a glossy substrate – the printout is shiny. If the surface of the material is matte – the printout is also matte. If we print on a material with a distinct surface texture, such as leather or canvas – the finished print looks the same as the substrate.
The thin layer of dye is very flexible. Nano prints can be bent, cut, stamped and thermoformed.
VIVID, CLEAN, SATURATED COLORS – HIGH LIGHTFASTNESS OF PRINTS
One of the additional positive features of printing with nanopigmented inks is the phenomenon of very even reflection of the light from the printed surface.
In the case of prints made in the majority of classic printing technologies, the printed surface reflects incident light in a non-uniform way, at the same time scattering a large part of it. Such dispersion causes the color effect visible to the observer to be muffled and slightly grayed. The surface printed with a nanoparticle pigment over 90% of light reflects in a regular manner, giving the observer the effect of clean, perfectly saturated colors.
ECOLOGY, OPERATOR COMFORT, ENVIRONMENTAL PROTECTION
There are several reasons why we can consider nanoprint technology as an ecological solution:
Nano-pigmented inks are not aggressive. NANOO technology based on solvents classified as non-toxic. After solvent evaporation prints are harmless and odorless.
Nano inks are extremely efficient, so we use very little. The amount of waste generated during the use of the printer is also minimal. Nanoprinters are energy-saving devices.
The use of nanoprint encourages the use of natural, ecological substrates such as glass, metals, ceramics, marble, granite, natural fabrics, paper, leather and many more.
