Rotogravure Inks. Since there are no mbber or plastic components in contact with the solvents contained in gravure ink formulations, it is permissible to use solvents such as ketones and aromatic hydrocarbons which cannot be tolerated in flexo inks. This provides the gravure ink formulator with much greater latitude in regard to binder selection. In other respects the compositions generally are similar. 

Water-based flexo inks can be formulated with either a soluble toner or with the Day-Glo EPX Series which is a tme pigment and can be formulated like a conventional pigment dispersion. The Radiant Aquabest or the Day-Glo WST can be formulated in an alkaline water-soluble system to yield strong inks. They have limited shelf life and inferior fade, but do not necessarily requite additional binder. Day-Glo EPX must be formulated with a binder such as a hard resin or can be used with one of the soluble toners such as WST. The EPX Series has several advantages over soluble toners such as much superior fade, exceUent ink stabiHty, and some hiding power over kraft-type papers. A disadvantage of the EPX is its lower tinctorial strength than other fluorescent toners. 

Since the prints do not tolerate calandering, the pigment is primarily used in offset inks, as well as in packaging gravure inks and in flexo inks. 

Compared to P.R.146, lower pigment area concentrations of P.R.147 are less lightfast. 1/1 SD letterpress proof prints equal step 5 on the Blue Scale for lightfastness, and 1/3 SD specimens match step 4, while 1/25 SD prints are equal to step 3. P.R.147 is used in offset inks, in packaging gravure printing inks, and in various flexo inks. Like other Naphthol AS pigments, P.R.147 is also employed in a series of special applications. 

It is described as bright yellowish orange and can be used for aqueous flexo inks and in the plastics application in dibutyl phthalate paste as plastiziser for PVC. Dyeing of technical leathers is as well described. 

P.O.67 is also recommended for printing inks, especially for flexo inks on NC base. Special pigment preparations for this application are on the market. 

UV curable flexo ink for RFID antennas Radio frequency identification (RFID) devices and contactless smart cards are capable of uniquely identifying an individual or object when they are interrogated by an external radio frequency signal. Recently, a process of printing with the use of UV curable conductive flexo inks has been introduced. The inks are based on polyfunctional acrylates with silver flakes added for the electrical conductivity. The advantages of these inks are ...

The product from a secondary fiber preparation plant for white grades is usually called DIP (Deinked Pulp) as there is at least one process step for ink removal integrated in the system. In most of the cases this deinking step is done by selective flotation. Washers may be used for deinking in special cases when very finely dispersed printing inks (like water-based flexo inks) are present in the recovered paper or when not only the ink, but also the major share of the ash content needs to be removed, as is true e. g. for tissue grades.

There are three main flexographic ink systems - water-borne, solvent-borne, and UV The primary difference between these ink systems is the method used for drying or curing the ink. Water and solvent-borne inks are dried by evaporation, whereas UV-cured inks are cured by chemical reactions. Flexo inks contain components that are responsible for several main functions, including solvents, colorants, resins, additives, and (for ultraviolet inks) UV-curing compounds.
