Solvent Based Ink

UP45 Half-Inch 42 ml White Solvent-Based TIJ Industrial Ink Cartridge
Compatible with HP 2580/2590｜Marking on Dark Substrates

Product Features

The UP45 half-inch white solvent-based cartridge forms its image by covering the background colour, solving the problem of dark surfaces that ordinary ink cannot mark. It is the primary choice for printing dates, batch numbers and specification markings on dark-coloured products.

Product Specifications

Advantages of the UP45 Half-Inch White Solvent Cartridge

Substrates Suited to White

White is intended for dark and mid-dark substrates. It is almost invisible on white or light surfaces, so please confirm the background colour of the print surface before selecting it.

Commonly printable surfaces:

• Dark plastics: black ABS, black PP, PE, dark PVC and dark PET 
• Wire, cable and hose: black cable sheathing, hydraulic hose and dark-sheathed tubing
• Dark glass: amber bottles, dark green bottles and dark coated glass
• Dark films: black, dark brown and dark blue flexible plastic films
• Dark paper: dark corrugated board and black card
• Dark metal and rubber: black painted parts, dark anodised aluminium parts and black rubber components

Please note: white is not suitable for white or light-coloured substrates. For light surfaces, please evaluate black solvent ink instead. White colourants have a higher specific gravity, so shake the cartridge gently before use and keep up a routine of regular test prints. Surface material, coatings, temperature and humidity all influence adhesion and drying performance. We recommend sample testing before full production to confirm the most suitable ink formulation and equipment parameters.

White vs. Black Solvent Ink Cartridges Comparison

White and black sit at opposite ends of the contrast scale; choose the cartridge colour according to how light or dark the printing surface is.

If the print surface is a white bottle, a label or transparent film, please evaluate the black solvent-based ink cartridge instead.

For the full colour range and the differences between half-inch and 1-inch specifications, see the UP45 Half-Inch 42 ml Solvent-Based TIJ Industrial Ink Cartridge series overview.

Compatibility Check

The half-inch white solvent-based ink cartridge is compatible with most non-encrypted half-inch coding systems on the market. Besides replacing the common HP 2580 and HP 2590 cartridges, it also suits a wide range of handheld and inline TIJ coders.

Purchasing scenarios suited to the white cartridge:

Marking black cable or dark bottles is commonly done by applying a white label first and then printing on it — an extra process step, and one where the label easily lifts or peels in damp or abrasive conditions. Printing directly in white ink removes that step entirely.

Wire and cable plants producing black cable and hydraulic hose; health supplement and chemical companies using amber bottles and dark containers; and electronics and appliance component manufacturers producing dark plastic housings. It also suits packaging plants, system integrators and coding equipment suppliers.

Use and Storage Recommendations

Storage conditions:

• Avoid direct sunlight
• Keep away from environments with excessive dust
• Do not store upside down for extended periods

Usage:

• When pausing use, refit the cartridge into its protective clip so the printhead is not left exposed for long periods
• Use within six months of opening
• Even with no immediate printing requirement, run a test print roughly every two weeks to extend cartridge service life
• When changing colours, remove the original cartridge and store it separately; never mix inks of different colours in the same cartridge
• Ink is not edible. Keep out of reach of children; avoid contact with skin and eyes and rinse promptly with clean water in case of contact
