Special water-based ink for plain paper, craft colored paper, art paper and packaging paper surface & through-dyeing processes. Eco pure water formula low VOC and odor-free for safe compliance. Excellent ink penetration & wetting with even transparent tinting, consistent color free of mottling and color spots. Compatible with all paper dyeing machines and flexo coloring equipment with smooth fluidity free of screen clogging, uniform color after printing. Tough film resistant to fading after long storage, the preferred eco consumable for craft paper, gift wrapping and special paper coloring processing.

Core Product Features

1. Eco Odor-Free Safe Compliance:

Pure water benzene-free heavy-metal-free low VOC irritation-free with no residual printing odor complying with paper eco standards for all

civilian & craft packaging paper.

2. Even Through Penetration:

Superior paper wetting & penetration delivering uniform transparent tinting for surface and light through-dyeing, eliminating mottling, uneven

depth and show-through.

3. Ultra-Fine Spot-Free Smooth Surface:

 Ultra-fine evenly dispersed ink free of particle impurities for clean spot-free colored paper with smooth premium craft texture.

4. Strong Adhesion Anti-Fading:

Firm bonding with paper fibers, stable color layer after curing resistant to mild rubbing without fading or whitening for long shelf life consistent

print effect.

5. Stable On-Press Anti-Clog Plate:

Moderate fluidity low foaming & sedimentation free of screen/plate clogging during long continuous coloring with consistent batch color depth.

6. Fast Drying Anti-Blocking High Production Efficiency:

Rapid room-temperature curing without stacking adhesion, eliminating long airing time for mass paper coloring processing.

How to choose:

1. By Paper Substrate:

General penetration grade for plain thin paper; high even anti-mottling grade for loose porous craft paper.

2. By Dyeing Effect:

Transparent light tint grade for surface coloring; high-concentration high-hiding grade for deep full through-dyeing.

3. By Machine Speed:

Fast-drying anti-clog grade for high-speed continuous dyeing equipment; stable easy-adjust general grade for semi-automatic manual dipping

& coloring.

How to use:

1. Pre-print Adjustment:

Stir ink thoroughly after opening to eliminate sediment and uniform tint depth. Only adjust concentration/viscosity with small repeated clean

water additions; no solvents/additives allowed. Fully clean screens and rollers to remove impurity contamination.

2. On-Press Coloring:

Adjust machine speed & pressure according to paper thickness and coloring demand for even ink coating. Refill and stir ink regularly during

continuous runs for consistent concentration.

3. Drying & Stacking:

Maintain well-ventilated workshop to accelerate ink penetration & curing. Avoid heavy tight stacking of incompletely dyed paper to eliminate

sticking back, color smudging and mottling.

4. Shutdown & Storage:

Seal ink tightly during short stops to prevent skinning & drying. Fully clean equipment pipelines and screens after long shutdowns. Seal 

unused ink and store in cool shaded places, use quickly.

Q1: Is this paper dyeing ink eco-friendly and odorless?

Pure water eco formula benzene-free heavy-metal-free low VOC odor-free with no residual smell after dyeing fully complying with paper eco standards for craft & packaging paper coloring processing.

Q2: What is the difference between dyeing ink and regular printing water-based ink?

Optimized for full paper penetration & even coloring, solving mottling, poor penetration and large color deviation of general ink on paper, more suitable for full paper tinting processes.

Q3: What causes uneven mottling after paper dyeing?

Caused by insufficient ink stirring, unstable viscosity or inconsistent paper transport speed. Stir thoroughly before use and fix machine parameters during production for consistent even coloring.

Q4: What causes color spots and rough paper surface after dyeing?

Sediment not fully mixed or residual equipment impurities. Stir thoroughly and filter ink before use, clean screens & rollers regularly for spot-free smooth paper.

Q5: How to solve screen clogging and sedimentation during continuous dyeing?

Caused by long ink standing and unbalanced concentration. Stir ink regularly during production and avoid excessive water dilution to maintain stable ink system free of sedimentation & screen blockage.

Q6: What causes sticking back after dyed paper stacking?

Insufficient ink curing. Boost workshop ventilation and extend drying time, only stack paper after full ink curing to eliminate color smudging & sticking back.

Q7: How to select suitable ink for different paper materials?

General grade for regular toilet & printing paper; high penetration anti-mottling grade for ultra-thin soft craft paper; high adhesion grade for high-density embossed paper.

Q8: Can water be added to dilute and what is the ratio?

Only pure water dilution permitted, no solvents. Add small amounts repeatedly according to machine speed and temperature to avoid excessive water reducing tint depth and penetration effect.

Q9: How to store ink and what is the shelf life?

Seal and store in cool dry shaded places protected from high/low temperature and sunlight. Tighten bucket lid during short stops to prevent skinning. Unopened ink has stable 12-month shelf life, stir well after standing before use.

Q10: Can ink with sediment after long storage still be used?

Light sediment is normal physical phenomenon; stir thoroughly before use without affecting dyeing effect. Discard if caking or non-uniform mixing occurs.
