PIGMENT RED 57:1/ HP RED 2539

What Is Pigment Red 57:1

Pigment Red 57:1 (C.I. 15850:1) is a monoazo lake pigment valued across the printing ink industry for its high color strength, bluish-red masstone, and exceptional cost-performance ratio. It is the workhorse red organic pigment in global printing ink production.

Why Choose HP RED 2539

HP RED 2539 is Honor Pigments’ yellowish-red PR57:1 grade, delivering a warm, golden-toned red that excels in packaging designs dominated by orange, yellow, and warm brown palettes. Unlike the bluish-red HP RED 2540 which serves as a process magenta, the 2539 provides the warmer shade preferred for food packaging where appetite appeal is key — snack foods, baked goods, and confectionery. Its yellow undertone enables cleaner yellow-over-red trapping in multi-color gravure printing, reducing the risk of muddy overprints when warm reds sit under yellow inks. The high transparency further enhances its performance in multi-layer laydown sequences on flexible substrates.

Key Features

• Yellowish-red masstone with warm golden undertone — ideal for food packaging where appetite appeal matters
• Complementary to HP RED 2540 (bluish-red): choose 2539 for warm reds and orange/yellow-dominant designs, 2540 for cool reds and process magenta
• High transparency optimized for multi-layer gravure and flexo printing, with excellent gloss and clarity in NC and PVB solvent systems
• Superior yellow-over-red trapping — the yellow undertone produces cleaner overprints when warm reds sit under process yellow
• Consistent batch-to-batch optical properties under ISO 9001 manufacturing

Recommended Applications

Primary: Multi-layer gravure packaging inks for food packaging — snack foods, baked goods, confectionery — where warm, appetizing reds are specified. High-transparency flexo inks and process color ink sets requiring clean yellow-over-red overprint behavior in warm color palettes.

Secondary: Premium offset inks where gloss, transparency, and a warm red shade are specified. Shade selection guide: If your print job requires a cool, bluish process red (standard CMYK magenta), use HP RED 2540 instead. If you need a warm, yellowish red for food or warm-toned packaging, HP RED 2539 is the correct choice. Not suitable for applications requiring high opacity or outdoor durability.

Technical Data:

• Light fastness: Light fastness rating is assessed on 1 to 8 Blue Wool scale where 1 = ‘Poor’ and 8 = ‘Excellent’.
• Heat Stability : Heat stability values given indicate the maximum temperature at which the pigment can be stoved for 10 min. on the full shade and in reductions without undergoing any significant change in shade.
• Oil absorption: The oil absorption is determined on the basis of EN ISO 787-5 and given in g linseed oil per 100 gm. pigment.
• Solvent bleeding: The bleeding in solvents is tested using the powder grades and the visual rating given on 1 to 5 Grey scale
  where 1 = ‘Heavy bleeding’ and 5 = ‘No bleeding”
