Inks Imerys minerals for enhanced performance in inks

Imerys offers a unique portfolio of high performance kaolins, ground calcium carbonates (GCC), precipitated calcium carbonates (PCC), and talcs to improve the properties of flexographic, offset and rotogravure inks. They can also be used to extend TiO2 in water and solvent based inks. Being a natural mineral product, every deposit has its own characteristics and these result in different properties being obtained.

Flexographic inks

Used in flexographic printing inks, Imerys calcium carbonates, kaolins and talcs:

  • Increase dry hiding on porous substrates
  • Maintain whiteness and opacity
  • Are effective TiO2 extenders, reducing formulation costs
  • Improve color performance 
  • Control gloss / matt
  • Improve ink transfer providing a clean print

We recommend:

  • Kaolin: NeoGen® 2000, Hydrite® UF90S
  • Carbonate: Supermite®

For water-borne and solvent-borne packaging inks and varnishes.
 

Offset inks

In offset printing inks, high performance, kaolins and treated calcium carbonates:

  • Improve lithotronic behavior 
  • Provide good water uptake without washout or bleeding into the fount solution
  • Maintain color strength
  • Provide good pigment efficiency and ink mileage
  • Reduce ink penetration into paper fibers
  • Improve hold-out and reduce strike-through
  • Can be used at high addition levels, reducing costs

We recommend:

  • Kaolin: Hydrite® RS, Hydrite® N and Hydrite® TS90 and Hydrite® UF90
  • Carbonates: Supercoat®  and ImerPrint 95L


Rotogravure

Used in rotogravure printing inks, Imerys calcium carbonates, kaolins and talcs:

  • Increase dry hiding on porous substrates
  • Maintain whiteness and opacity
  • Are effective TiO2 extenders, reducing formulation costs
  • Improve color performance 
  • Control gloss / matt
  • Improve ink transfer providing a clean print

We recommend:

  • Kaolin: Hydrite® UF90, Hydrite® TS90

For water-borne and solvent-borne packaging inks and varnishes.
