Abstract

Cilj ovog završnog rada je dati uvod u nanografski tisak kroz opis principa rada nanografije, te bojila i strojeva koji se koriste. Nanotehnologija se bavi istraživanjem i manipulacijom materijala u atomskom, molekularnom ili makromolekularnom obliku. Materijali u nano obliku pokazuju potpuno drukčija električna, optička, magnetska i mehanička svojstva nego na makroskopskoj veličini. Nanografija je nova tehnika digitalnog tiska koju je izumio Benny Landa nakon proučavanja nanopigmenata. Oni su snažni koloranti i apsorbensi svjetlosti i temelj su NanoInka, bojila na bazi vode koje se koristi u nanografskom tisku. Tisak započinje štrcanjem kapljica bojila na zagrijanu prijenosnu traku. Voda iz bojila na traci isparava te se na tiskovnu podlogu prenosi suhi polimerni film debljine oko 500 nm. Tisak je moguć na svim podlogama jer se boja prenosi suha, pa nije potrebno naknadno sušenje i otisak je odmah spreman za upotrebu. Tanki film bojila na podlozi i nanopigmenti daju visokokvalitetne otiske, uz uštedu energije i količine bojila potrebnog za tisak. Strojevi su dizajnirani za tisak na arke (B1-B3 formati) i tisak iz role, s mogućnošću višebojnog tiska sa 4 do 8 boja. Nanografskom tiskom omogućen je tisak gotovo svih grafičkih proizvoda; publikacija, komercijalnog tiska , tiska sklopivih kutija i tiska ambalaže.

Abstract (english)

The aim of this work is to give an introduction into nanographic printing through a description of the nanographic print process, and the inks and the machines used. Nanotechnology is a science of manipulating matter on the atomic, molecular or macromolecular scale. Materials in their nano-form exhibit different essential properties than on a macro-scale: different electronic, optical, magnetic and mechanical properties. Nanography is the new method of printing, developed by Benny Landa, during his study of nanopigments. Nanopigments are strong colorants and absorbents of light and are foundation for NanoInk, water-based ink for nanographic printing.

The printing process begins with the injection of droplets of ink on a heated transfer blanket.

The water evaporates upon coming into a contact with the blanket, thus leaving a trail of dry, around 500 nm thick polymer film on the surface. Such printing is possible on every surface because the ink is printed dry, without requiring a subsequent drying phase, and as such the imprint is instantly ready for use. The thin layer of the ink on the surface and nanopigments provide a high quality imprint, with optimal use of energy and ink. The printing machines are designed for sheetfed printing (B1-B3 format) and web press. Nanographic printing can be utilized in a variety of graphically printed products; publications, commercial prints, cardboard-box prints and other packaging.
