Why Choose Goking?
Plateless, Instant Job Changeovers
No plates, no screens, no setup waste. Operators load a digital file and begin printing in under one minute — compared to hours of plate-making and registration on traditional flexo lines. This unlocks profitable short-run production and eliminates make-ready material waste entirely.
Single-Pass Speed up to 110 m/min
G-series single-pass systems print all colors in one pass through a stationary printhead array. Epson configurations run at 45–80 m/min, while Seiko-equipped machines reach up to 110 m/min — 4 to 10 times faster than multi-pass, matching flexo throughput without any plate-related costs.
Three Printhead Platforms, One Fit
Epson (8–32 heads, 600/1,200 DPI, five-color CMYKW) for premium detail. Xaar (6–12 heads, grayscale) for high-viscosity reliability. Seiko (4–18 heads, up to 1,800 mm) for large-format speed. Every machine is configured to the converter's exact requirements — no one-size-fits-all compromise.
Seamless Inline and ERP Integration
Goking machines connect directly to die-cutters, folder-gluers, and stackers for continuous production flow. ERP connectivity enables automated job dispatch, real-time tracking, and digital inventory management — turning a manual print floor into a data-driven operation.

How UV Ink Creates Water-Resistant Prints
The water resistance of UV-curable ink is a fundamental property of its chemistry. UV ink consists of monomers, oligomers, photoinitiators, and pigments. When exposed to ultraviolet light, the photoinitiators trigger a chain reaction called free-radical polymerization — the liquid monomers and oligomers link together into long polymer chains, forming a cross-linked solid network that encapsulates the pigment particles.
This cross-linked polymer film is fundamentally different from the dried residue of solvent-based or water-based inks. Solvent inks dry by evaporation — the solvent evaporates, leaving pigment and binder on the substrate. This residue can be re-dissolved or softened by water or solvents. UV ink's polymer film is chemically inert and insoluble — water cannot dissolve it, and the pigment particles are locked within the polymer matrix, unable to migrate or bleed.
The practical implication for packaging converters is significant. Packaging printed with UV ink can withstand condensation in refrigerated transport, moisture exposure in outdoor storage, water splash in food and beverage environments, and humidity in tropical climates — all without degradation of print quality or color accuracy. This water resistance is a property of the ink itself, not an additional coating or treatment.
Comparing Ink Technologies for Water Resistance
Understanding how different ink technologies perform in wet environments helps converters select the right system for their application requirements.
| Ink Type | Water Resistance | Curing Mechanism | VOC Content |
|---|---|---|---|
| UV-curable (Goking) | Excellent — cross-linked polymer | UV LED photopolymerization | Zero |
| Solvent-based | Moderate — resin residue | Evaporation | High |
| Water-based dye | Poor — dye re-dissolves | Absorption + evaporation | Low |
| Water-based pigment | Moderate — binder dependent | Absorption + evaporation | Low |
| Latex | Good — polymer film | Heat evaporation | Low |
The comparison clearly shows UV-curable ink's advantage for water-resistant printing. The cross-linked polymer film created by UV photopolymerization provides a level of water resistance that solvent, water-based, and latex inks cannot match without additional protective coatings. For converters producing packaging that will encounter moisture during its service life, this built-in water resistance eliminates the need for secondary lamination or varnishing steps.
Applications Requiring Water-Resistant Pigments
Water-resistant digital printing serves numerous packaging and product applications where moisture exposure is expected or unavoidable. Understanding these applications helps converters identify market opportunities for water-resistant printing capability.
Beverage packaging — Bottles, cans, and cartons that are stored in refrigerators or coolers experience condensation. Water-resistant pigments ensure that branding, barcodes, and product information remain legible and attractive even when wet. Beverage carriers and multi-packs printed with UV ink maintain their appearance throughout the cold chain.
Food packaging — Frozen food cartons, refrigerated product packaging, and packaging for moist products (fresh produce, seafood, dairy) require prints that survive condensation and direct moisture contact. UV ink's water resistance ensures that nutritional information, ingredients lists, and barcodes remain readable under these conditions.
Industrial packaging — Chemical containers, lubricant packaging, and industrial product boxes are often stored outdoors or in uncontrolled environments. Water-resistant pigments ensure that hazard warnings, product identification, and handling instructions remain visible regardless of weather exposure.
Outdoor packaging and displays — Retail displays, point-of-purchase materials, and outdoor product packaging must withstand rain, humidity, and temperature fluctuations. UV ink's combination of water resistance and UV light resistance (the cured polymer film resists yellowing and fading) makes it suitable for these demanding applications.
Agricultural packaging — Fertilizer bags, seed packets, and produce packaging are exposed to soil moisture, irrigation, and varying humidity levels. Water-resistant pigments ensure that planting instructions, product information, and batch codes remain legible throughout the product lifecycle.
Goking Printer Configurations for Water-Resistant Printing
All Goking digital printing systems use UV-curable ink, which means every configuration in the product range produces water-resistant prints. The choice of configuration depends on production volume, substrate type, print width, and quality requirements rather than on water resistance — that capability is standard across the entire range.
For high-volume water-resistant packaging production, the G-series single-pass with 24 or 32 Epson printheads delivers 45 to 80 meters per minute with CMYK plus white capability. For premium quality water-resistant printing, the J-series multi-pass at 1200 DPI provides the resolution needed for fine text and detailed graphics. For wide-format applications, the industrial-grade Seiko configuration covers print widths up to 1,800 millimeters at speeds up to 110 meters per minute.
The GJ series 2-in-1 provides dual-mode capability for converters who need both high-resolution short-run water-resistant printing and high-volume production. This flexibility is particularly valuable for packaging businesses that serve diverse clients with varying volume and quality requirements, all needing the water-resistant properties of UV ink.
Testing and Verifying Water Resistance
Water resistance is a quantifiable property that can be tested using standardized methods. Converters producing packaging for applications where water resistance is critical should implement testing protocols to verify print durability.
Rub test — A printed sample is rubbed with a wet cloth or finger under controlled pressure. Water-resistant prints show no ink transfer to the cloth and no color change on the print. UV-cured ink on corrugated board, kraft paper, or coated paperboard passes this test without difficulty.
Immersion test — A printed sample is submerged in water for a specified duration (typically 30 minutes to 24 hours). After removal, the print is inspected for color bleeding, ink detachment, or substrate degradation. UV ink's cross-linked polymer film maintains integrity during immersion, though the substrate itself (particularly uncoated paper) may weaken.
Condensation test — Printed samples are placed in a high-humidity chamber where condensation forms on the surface. This simulates refrigerated storage conditions. UV ink prints maintain their appearance under condensation without running or smearing.
Important Note: While the UV ink film itself is water-resistant, the substrate may not be. Corrugated board and kraft paper absorb water and lose structural strength when wet. For applications where both the print and the substrate must survive water exposure, water-resistant substrates (coated board, synthetic paper, or plastic-coated board) should be used in combination with UV ink.
Beyond Water Resistance: Additional UV Ink Durability Properties
Water resistance is one of several durability properties that UV-cured ink provides. The cross-linked polymer film also offers resistance to other environmental factors that can degrade print quality over time.
Abrasion resistance — The cured ink film resists scuffing and rubbing during transport, handling, and shelf display. This is critical for shipping packaging that undergoes automated sorting and conveyor transport, where surface contact can wear away less durable ink systems.
Chemical resistance — UV ink films resist common chemicals including mild acids, bases, and solvents. This is relevant for industrial packaging that may contact chemical products and for food packaging that may encounter cleaning solutions during processing.
Light fastness — UV-cured ink pigments resist fading under exposure to ultraviolet light. This is important for packaging displayed under retail lighting or in window displays where sunlight exposure may occur.
Frequently Asked Questions
Is water-resistant the same as waterproof?
Water-resistant means the print can withstand exposure to water without degrading, but it is not rated for continuous submersion. Waterproof implies complete impermeability. UV ink prints are water-resistant — they survive splashes, condensation, and brief immersion, but are not designed for continuous underwater use.
Do I need a special machine for water-resistant printing?
No. All Goking digital printing systems use UV-curable ink, which is inherently water-resistant. Any Goking machine configuration — J-series, G-series, GJ series, or industrial-grade — produces water-resistant prints as a standard property of the ink chemistry.
Can water-resistant prints be recycled?
UV ink on paper substrates can be recycled through standard paper recycling processes. The cured ink film is removed during the de-inking stage of paper recycling. However, recyclability depends on local recycling facility capabilities and the specific substrate used.
How long do water-resistant UV ink prints last outdoors?
UV ink prints resist water and UV light degradation, but outdoor durability depends on exposure intensity, climate conditions, and substrate choice. For permanent outdoor applications, substrate selection and overprint varnishes can extend service life. Specific durability projections should be tested under actual use conditions.
Selecting a Printer for Water-Resistant Applications
