Products For Pied Papers             Blacks Small particle size, longer bodies and blue undertones are considered the trade-mark of quality black inks. To bring the best commercial product to pass, we are well instructed to look beyond the available solutions.     One such product ‘BLACK BEAUTY’       is nonsuch.       Pigments of high loading capacity, the unique blend of vehicles of identical refractive indexes, the perfect choice and contribution of flow agents for transfer of more than 60% from the plate along with the desired oil & toner absorption properties makes it perhaps the most dense ink an ink maker had rather produced. It records consistent prints of density more than 4  in a densitometer at optimum ink film thickness.         Process colours Process inks are designed for faithful reproduction of fine half-tones and solids on variety of substrates by     producing inks of high intrinsic strength,       good flow - not at the expense of transparency and strength.     following BS 1480/1949 and BS 3020       standards for colour shades as a result of - cyan of green shaded copper phthalocyanine blues, magenta from fanal pink and little calcium 4b and yellow - one opaque for first down printing and one transparent for printing in any sequence.     formulating for printing sequence as       tack rated inks for better trapping.         Matching colours We match all Pantone colours and colours otherwise specified, under the following rules.     All our colour matchings are conducted       under direct light from a northern sky or colour matching lamp at a 5000oK colour temperature - quantity of illumination > 100 foot candles.     Colours are matched not only for hue       but also for bronzing and sheen.     The prints are observed wet for any       change in appearance during drying and after drying.     Difference spotted by transmitted light is       also observed. We take into account, induced contrasts that affect the colour match.         Metallic colours Our unique polymer technology in varnish manufacturing now allows gold, silver inks to be printed without much difficulty. We use a range of colouring materials, including aluminium powders, copper and copper alloy powders for the purpose.     These powders are not ground too fine,       yet does not pile up in the plate and blanket giving excellent luster finishes.     The shelf life is also supposedly more       than the usual standards.       Inks containing mica pigments, coated with titanium-di-oxide is produced for shiny metallic or pearlescent effects.         Flourescent colours Flourescent and phosphorescent inks are available which give a variety of special effects.     Fluorescence - speciality pigments are       used which absorb UV energy and virtually immediately re-emit this energy. The effect of this is to cause the print to glow and appear bright in daylight conditions - available as green, magenta and yellow.     Phosphorescence - contain activated       zinc sulphide of relatively larger particle size, which has the ability to absorb light energy and re-emit this energy over a long period of time. These inks glow in the dark for upto a couple of hours after daylight has ended.         Invisible colours A novel type of ink system that is available with us for quite sometime now.     Transparent inks that contain materials       that fluorescence under “black light” (ultraviolet) are invisible in ordinary light. These are meant for printing identity to guard against duplicates.     Supplied in different colours,       depending on the fondness.
