5X500ML UV LED Ink CMYKW for R1390 L800 A3 A4 UV Printer - Versatile

In this review the 5X500ML UV LED Ink set is evaluated for small print shops and hobbyists who need a ready color pack for R1390 and L800 style printheads. The bottom line: this kit is best for direct-to-substrate UV printing on items like holsters, leather and soft PVC because it provides a full CMYKW set in five 500ml bottles and is formulated as a soft UV ink that adheres well to flexible materials. The most important reason to consider it is the combination of volume and compatibility with common A3/A4 UV printers, making it a practical refill option for frequent jobs.

Key Features

• Packaging: The set includes five 500ml bottles, giving a practical amount of ink for repeat jobs without frequent reorders.
• Color set: Cyan, Magenta, Yellow, Black and White are included so users can print both full color and spot white layers for opaque prints on dark substrates.
• Soft UV formula: The ink is designed for soft surfaces such as holster material and soft PVC, reducing cracking on flexible parts after curing.
• Compatibility: Labeled for R1390 and L800 printhead style A3/A4 UV printers, it fits common small-format direct-to-object workflows.
• Active product handling: Bottles are active and need shaking before use, which helps maintain pigment suspension for consistent output.
• Delivery: Typical delivery is ETA 4-8 days, allowing shops to plan stock and avoid downtime between jobs.

Who It's For

This ink set suits small commercial printers, personalization shops and experienced hobbyists using compatible A3 or A4 UV LED printers who need a reliable supply of CMYKW and print on flexible or textured substrates like leather, soft rubber shells and advertising cloth. The 500ml bottle size balances cost and shelf rotation for users with steady print volume.

Users who require long open-bottle shelf life after opening, detailed technical support for industrial press setups, or guaranteed manufacturer warranties for specific OEM printers should look elsewhere, as the product notes a three month shelf life after opening and uses active handling instructions rather than extended storage guarantees.

Pros & Cons

Pros

• Complete CMYKW set in substantial 500ml bottles reduces refill frequency for small shops.
• Soft UV formulation improves adhesion and flexibility on leather, holster material and soft PVC.
• Clear handling instructions such as shaking before use help maintain print consistency.

Cons

• Shelf life is limited to three months after opening, which requires careful inventory planning for low-volume users.
