Published grades represent standard production benchmarks. Backed by HCOLOR's National Engineering Center, we recalibrate chemical matrices, viscosity curves and drying windows to match your unique pressroom variables:
WFG50000 delivers strong ink transfer, low residual solvent values, and clean release from gravure cells. It is engineered to withstand secondary adhesive coating without ink bleeding or delamination.
| Solid Content | 36 ± 2% |
|---|---|
| pH Value | 8.2 – 9.0 |
| Viscosity | 14 – 18 s (Zahn #3, 25°C) |
| Bond Strength | ≥ 2.0 N/15mm (BOPP/VMCPP) |
| Storage | 12 months, 5 – 35°C, sealed |
The laboratory parameters published above reflect standard benchmark batches tested under controlled baseline conditions. In industrial pressrooms, coating performance is governed by multiple variables—including anilox screen volume and cylinder cell depths (15–45 μm), drying tunnel length and airflow dynamics, substrate surface tension, and seasonal workshop temperature/humidity fluctuations, alongside solvent-to-water transition requirements.
Backed by our National "Little Giant" R&D Center and Provincial Engineering Laboratories, HCOLOR offers on-demand formula recalibration. Our ink chemists fine-tune resin matrices, viscosity curves (15–45s), evaporation rates, and functional additives to seamlessly adapt to your plant's printing presses. HCOLOR application specialists also provide on-site press trial verification and remote spectrophotometric support, ensuring stable transfer and high runnability without risking production downtime.
The foundational quality management system accreditations, environmental certifications, and general regulatory attestations displayed above (including ISO 9001:2015, ISO 14001:2015, ISO 45001:2018, and China Environmental Labelling "Ten Rings") represent HCOLOR's corporate manufacturing governance and baseline formulation safety standards across our production facilities.
In commercial conversion, specific ink formulations and sub-models comply with specific international directives and migration thresholds (including US FDA 21 CFR 175.300 / 176.170 indirect food contact criteria, China National Food Safety Standard GB 4806.10, EU REACH Regulation (EC No 1907/2006) SVHC candidate screening, RoHS 2.0 heavy metals exclusion, and Tobacco Industry VOCs Standard YC/T 207).
Because barrier properties and migration values depend heavily on press substrates (e.g. virgin folding boxboard, PE extrusion coatings, metallized transfer paper, or PET/BOPP films), coat weight, and pressroom drying configurations, official third-party test reports (from accredited bodies such as SGS, CTI, and PONY) and batch-specific compliance certificates are provided upon formal inquiry and pressroom trial verification. Please contact our technical compliance team to verify documentation tailored to your exact application.
Engineering synergy across high-gloss varnishes, dead-matt coatings, digital primers and soft-touch tactile effects to solve specific converting challenges across global packaging sectors.

A rigorous 4-step engineering protocol designed to adapt custom resin matrices and viscosity windows to your exact pressroom specifications.
Tell us your substrate (BOPP, CPP, PET, PE, PVC, Kraft paper, gold/silver cardstock), press type (rotogravure, flexo, screen), line speed (150-400 m/min), drying tunnel specs, and target color standards.
Our senior ink chemists formulate eco-friendly water-based resin matrices and disperse high-purity pigments, achieving precise color coordinates (L*a*b*) under standard D50/D65 illuminants with ΔE < 0.8 spectral accuracy.
We dispatch 1-5 kg trial ink lots within 48h alongside detailed drawdowns and viscosity guidance. Our application engineers provide remote or on-site support to optimize ink transfer, drying speed, and adhesion.
Backed by Dongguan, Kunming, and Yueyang production bases (30,000+ tons annual capacity), orders undergo strict QC batch release before dispatch in palletised 20kg/200kg drums or 1000kg IBCs via sea/air freight.

Yes. Our color lab matches by spectrophotometry against your target, on your own substrate and printing process. Send us a printed sample or the reference values and we will return a matched draw-down for approval.
Standard shades ship from stock in 20 kg units. Custom-matched colors are typically produced from 100 kg upward, though we can supply smaller trial quantities for a first press qualification run.
Yes. We supply trial sample pails for press testing on your own line, together with technical support to fine-tune viscosity, anilox cell volumes, and curing/drying parameters.
Keep containers sealed and out of direct sunlight within the temperature range given on the technical data sheet (5–35°C for waterborne, 5–25°C for UV). Shelf life is 12 months from the production date.
Every shipment is accompanied by a Certificate of Analysis (COA) and Safety Data Sheet (SDS). Official test declarations including YC/T 207 (tobacco VOCs), GB 4806 / FDA (food contact), and China Environmental Labelling (Ten-Ring) are available on request.
