Pardad Rang Kahroba Series 50 inks are high-quality inks specifically designed for flexographic and rotogravure printing. This solvent-based ink series is suitable for soft aluminum foil. The foil must be primed with a special primer.

Technical Specifications:

• High color strength
• Excellent ink transfer
• Suitable for high-speed printing
• Heat resistance: 180-210 degrees Celsius
• Very good chemical resistance
• High adhesion
• Fine print resolution
• High heat resistance
• Micro printing
• Good solubility

Viscosity Adjusting Solvent: Pardad Rang Kahroba's ready-to-use solvent or a mixture of ethyl acetate and anhydrous isopropyl alcohol. Pardad Rang Kahroba's ready-to-use solvent is suitable only for flexographic printing systems.

• Flexo system: 80% anhydrous isopropyl alcohol or ethanol + 20% ethyl acetate (1:4)
• Gravure system: 50% anhydrous isopropyl alcohol or ethanol + 50% ethyl acetate (1:1)

 The mentioned ratios are approximate, and the exact values depend on various conditions. To slow down the drying of the ink, use ethyl glycol or methoxy propanol. To speed up the drying of the ink, use ethyl acetate.

• Flexo printing viscosity: 22-25 seconds at 25 degrees Celsius with a Ford Cup No. 4
• Rotogravure printing viscosity: 14-22 seconds at 25 degrees Celsius with a Ford Cup No. 4

Mix thoroughly before use.

Hue: Based on the shades available in the catalog, to reduce the shade of the inks, use Series 50 varnish.

Packaging: Colored inks in 20 kg polyethylene containers, white ink in 25 kg containers, or one-ton polyethylene pails.
