Digital Printing Machine with White Ink: Vibrant Prints on Dark and Kraft Substrates
Printing on dark or kraft paper substrates has long been a challenge for digital printing. Without a white underbase, colors appear muted and designs lose vibrancy against non-white backgrounds. A digital printing machine with white ink solves this problem by incorporating white ink (W) as a fifth color in the CMYKW system, enabling vibrant, opaque printing on dark, kraft, and colored substrates. Goking (cmyk-goking.com), based in Dongguan Huangjiang Town, Guangdong, manufactures five-color digital printing machines that leverage white ink technology to deliver premium packaging effects across the corrugated industry.
White ink transforms what is possible in digital packaging printing. It serves as both an underbase for CMYK colors on dark substrates and as a standalone design element, opening new creative possibilities for brands that want their packaging to stand out on retail shelves.
White Ink Technology for Premium Packaging
A digital printing machine with white ink uses the W channel in the five-color CMYKW system to deposit an opaque white layer on the substrate before or after the CMYK colors are applied. This white layer acts as a primer that prevents the substrate color from showing through, ensuring that CMYK colors appear as intended regardless of the background material.
Opaque Underbase for CMYK Colors: On dark or kraft corrugated board, white ink creates a bright underbase that allows CMYK colors to achieve their full vibrancy. Reds appear red rather than muddy brown, blues stay true rather than turning dark, and fine details remain crisp and visible against the substrate.
Kraft Substrate Printing: Kraft paper and kraft liner board are increasingly popular for eco-conscious packaging due to their natural, recycled appearance. White ink enables full-color digital printing on kraft substrates, allowing brands to maintain their earthy aesthetic while still delivering vibrant graphics and product information.
White as a Design Element: Beyond serving as an underbase, white ink can be used as a standalone color in packaging designs. White text, patterns, and accents on dark substrates create striking visual contrasts that elevate the perceived value of the packaging, making white ink particularly valuable for premium and luxury applications.
How White Ink Transforms Packaging Design
The addition of white ink to a digital printing machine fundamentally changes what packaging designers can achieve. Dark substrates that were previously limited to simple, single-color prints can now support full-color, high-resolution graphics. This opens new opportunities for brands to create distinctive packaging that stands out in competitive retail environments.
Premium Dark Packaging: Black, dark brown, and deep-colored gift boxes, retail packaging, and display materials can now feature vibrant, full-color designs thanks to the white ink underbase. This enables brands to use dark substrates for a premium look without sacrificing color reproduction.
Eco-Friendly Kraft Packaging: Natural kraft board conveys an environmentally conscious image, but printing vibrant colors on it has traditionally been difficult. White ink technology solves this, allowing brands to combine the eco-friendly appeal of kraft with the visual impact of full-color digital printing.
Seasonal and Limited-Edition Designs: White ink enables special edition packaging on dark or colored substrates for holidays, promotions, and limited-time campaigns. These distinctive designs help products stand out on shelves and create memorable unboxing experiences for consumers.
Five-Color CMYKW Printing System
Goking's five-color CMYKW system integrates white ink seamlessly with CMYK color channels. The five-color single-pass and multi-pass machine and the five-color multi-pass machine both support this configuration, giving manufacturers flexibility in choosing the production mode that matches their volume requirements.

Printhead Options for White Ink Printing
Goking offers two printhead platforms that both support the five-color CMYKW system with white ink:
Epson Printheads: 8 to 32 heads, 600/1200 DPI, Micro Piezo technology. The high resolution and precise droplet control of Epson printheads make them excellent for detailed white ink work on premium packaging.
Xaar Printheads: 6 to 12 heads, 1536/2560 active nozzles, 13-100pl drop size, up to 40kHz. The large drop size range of Xaar printheads is particularly effective for laying down opaque white ink coverage at high speeds.
Production Advantages
Goking's white ink digital printing machines share the same production advantages as the full product line. No plate-making is required, job changes take approximately one minute, and CMYK computer color matching ensures consistent results across runs. Adjustable DPI settings let operators optimize quality and speed for each job. Machines can connect inline with production lines and ERP systems, and low power consumption supports eco-friendly operation. The equipment weighs 3000-3500KG for industrial stability.

Frequently Asked Questions
What is white ink used for in digital printing?
White ink (W in CMYKW) serves as an opaque underbase that enables CMYK colors to appear vibrant on dark and kraft substrates. It can also be used as a standalone design element for white text, patterns, and accents on dark packaging.
Can white ink print on kraft corrugated board?
Yes. White ink is specifically designed to enable full-color printing on kraft and dark substrates. It provides the opaque base needed for CMYK colors to achieve their intended vibrancy on non-white surfaces.
Which Goking machines support white ink?
All three Goking series — J-series multi-pass, G-series single-pass, and GJ series 2-in-1 — support the five-color CMYKW system with white ink. Both Epson and Xaar printhead configurations are available.
Does white ink affect print speed?
White ink is deposited as part of the five-color CMYKW printing process. Multi-pass machines achieve 500-1500 m/h and single-pass machines reach 45-110 m/min, with white ink integrated into the standard print workflow.
Is white ink available with UV-curable waterproof inks?
Yes. The five-color CMYKW system uses UV-curable inks that provide waterproof and water-resistant prints, combining white ink capability with durable performance for outdoor and humid environments.
A digital printing machine with white ink from Goking unlocks the creative and commercial potential of dark and kraft substrate printing. By adding opaque white ink to the five-color CMYKW system, Goking enables packaging manufacturers to produce vibrant, premium-quality prints on any substrate — from natural kraft board to deep-colored gift boxes — with the speed, efficiency, and eco-friendly operation that modern packaging production demands.
