HP ORANGE 3440 / PIGMENT ORANGE 34

Pigment Orange 34 transparency version

Transparent P.O.34 versions represent the most frequent choice for printing inks. They provide a clean, yellowish orange hue and high tinctorial strength. P.O.34 is somewhat redder than the similarly strong P.O.13. At equal depth of shade, prints obtained from P.O.34 tolerate light better than do prints containing P.O.13; P.O.34 shows good solvent resistance to a number of organic solvents. Its prints are more stable in this respect than those made from P.O.13 Transparent P.O.34 is somewhat sensitive to heat and generally only withstands temperatures up to 100 to 140°C. Higher sterilization or metal deco printing temperatures may produce a color shift towards a redder orange. P.O.34 is used for all printing techniques. Packaging printing inks, especially nitrocellulose inks, often use the orange version of the cheaper and more lightfast P.O.5 in areas where fastness to organic solvents is unimportant.
