Rainbow Pigment Co., Ltd.

Rainbow Pigment Co., Ltd. is located in Taiwan and maintains a catalogue of ten active products. The company’s listings fall under four broad categories: Computer Printers & Materials, Printing Inks, Chemicals & Allied Products, and Leather Shoes. Within the Printing Inks segment the catalogue includes eco‑solvent, UV curable, barcode, and specialty chromo inks. Each product entry is identified only by its commercial name, for example Eco‑Solvent Ink or CHROMOINK LED UV ink for Leather, Yoga, Shoes. The product set does not include HS codes in the supplied data, but the items are typical of the ink families classified under HS heading 3215.

The eco‑solvent inks are formulated for use on roll‑to‑roll printers and are compatible with a range of substrates including vinyl and polyester. UV curable inks listed are designed for rapid curing under LED or mercury lamps, a common requirement in high‑speed graphic printing. Barcode inks are pigment‑based formulations intended for high contrast on paper and synthetic labels. The chromoink series includes food‑grade egg‑shell coding ink, textile fluorescent ink, and printer‑specific inks for models such as DX5, DTG, Konica 512i and Spectra Starfire. These product descriptions reflect the supplier’s focus on niche ink applications rather than bulk chemical commodities.

Rainbow Pigment’s ten listed products cover eco‑solvent, UV curable, barcode and several chromo‑ink variants. In the ink industry eco‑solvent formulations typically meet ISO 12647‑7 colour standards, have VOC contents below 300 g / L and are supplied in 1 L cans or 5 L pails. UV curable inks are usually evaluated against ASTM D‑3332 for cure speed and require a minimum 30‑second LED exposure; they are often packed in 200 L drums for bulk shipments. Barcode inks are pigment‑based, conform to ISO/IEC 15416 print quality specifications and are shipped in small containers for label‑maker integration. Chromoink products such as food‑grade egg‑shell coding ink and fluorescent textile ink follow industry‑specific grades like FDA food‑contact approval or colour fastness classifications (e.g., ISO 105‑B02).
