Deinking of crosslinked inks

• UV curable inks, varnishes: polyacrylates;photoinitiator induces polymerisation

• Mineral-oil free inks: plantseed oilscrosslink due to oxidative drying

• HP Indigo toner: polyethylene film, flexible, high cohesion

• Landa ink: also polymer film, transferredfrom blanket to paperCo
