This market segment includes metallizing, label grades, ink jet, thermal print and those perfume sample grades one finds in magazine ads. Label grades are usually C1S and use some of the same manufacturing strategies as coated woodfree. Most of these grades use woodfree fiber almost exclusively.  Most of them have requirements related to their print specialty. Ink jet requires a porous surface that will absorb and quickly capture the ink to prevent it from wicking and fuzzing out the print. High surface area pigments and cationically treated pigments like the PCC and GCC based Astra-Jet series are good pigments to use here. The cationic treatment captures the dye and keeps it from spreading and wicking.
