Baosiwei UV Printing Solution for Kraft Paper
Enhancing Kraft Paper Packaging with UV Digital Printing
Kraft paper has a natural brown tone that becomes part of the final print result. When CMYK inks are printed directly onto the surface, the paper color can affect the appearance of the printed image. This is especially noticeable in light colors, gradients, and highly saturated graphics, which may appear duller than intended.
Traditional printing remains a practical choice for standardized, high-volume packaging with relatively simple artwork. But when customers expect stronger color, better image reproduction, smoother gradients, and finer graphic details, print quality becomes a more important part of the packaging itself.
This is where UV flatbed printing can add value. By using white ink as a base layer followed by high-precision color printing, UV printing can enhance the visual performance of graphics on kraft paper. For packaging manufacturers that already use conventional printing equipment, UV printing does not have to replace the existing process. Instead, it adds another production option for higher-quality, higher-value packaging.

White Ink Underprinting for Better Color on Kraft Paper
The natural color of kraft paper can affect how CMYK inks appear.
When color is printed directly onto the brown surface, the paper tone visually interacts with the ink. Light colors are particularly sensitive to this effect.
A Baosiwei UV flatbed printer can first print a layer of white ink onto the kraft paper, followed by CMYK color printing.
The white ink can be thought of as creating a “white canvas” on the kraft paper. It provides a more neutral base for the color layer and helps reduce the visual influence of the paper's natural brown tone.
This is particularly useful for designs containing:
- Brand logos
- Product images
- Light-colored text
- Gradient backgrounds
- Multicolor illustrations
For simple text or single-color graphics, conventional printing may already meet the basic requirements. But when the packaging needs stronger color and more detailed visual presentation, white-ink UV printing provides greater design flexibility.

High-Resolution Inkjet Printing for More Detailed Graphics
Conventional printing has well-established advantages for standardized designs, fixed colors, and volume production.
However, once a packaging design includes product photography, complex gradients, multicolor logos, or fine graphic details, the question is no longer simply whether the artwork can be printed. Color reproduction, detail definition, and the ability to handle complex graphics become increasingly important.
UV digital printing works directly from digital artwork without plate making.
Baosiwei's JW-2513UV flatbed printer uses Ricoh G6 industrial printheads, with configurations from 2 to 8 printheads and a maximum printing resolution of 1200 dpi.
High-resolution inkjet printing can be used to reproduce details in product images, small text, fine lines, logos, and gradient graphics. When artwork changes, the digital file can also be updated directly without preparing a new printing plate.

What Kraft Paper Packaging Is Suitable for UV Printing?
UV printing is not intended to replace every kraft paper printing application. It is particularly suitable when the packaging requires stronger visual impact and higher print quality.
Kraft Paper Gift Boxes
Gift boxes, seasonal packaging, and customized packaging often contain multiple visual elements.
UV printing can reproduce product images, gradient backgrounds, brand logos, and detailed illustrations, giving kraft paper packaging more room for visual expression.
E-commerce Brand Packaging
For e-commerce brands that invest in visual identity, packaging is also part of the customer experience.
High-quality color printing can help reproduce product imagery and brand graphics more effectively on the packaging surface.
Agricultural Product Gift Packaging
Fruit boxes and agricultural product gift packaging can use product images, brand names, and decorative graphics to strengthen product recognition.
For cost-sensitive, high-volume products, simpler printing may be sufficient. For premium gift packaging, UV printing provides an option for stronger color and more detailed graphic presentation.
UV Printing Can Also Add Texture and Gloss Effects
UV printing is not limited to CMYK color output.
By building up multiple layers of UV ink, selected areas such as logos, text, or decorative graphics can be given a raised, tactile effect.
If the printer is equipped for varnish printing, clear UV varnish can also be applied to selected areas to create different gloss levels across the same packaging surface.
For packaging that requires additional finishing such as hot foil stamping, UV printing can be used as the digital printing stage before subsequent finishing processes.
UV printing handles the graphic output, while foil effects are produced through the corresponding finishing process. These technologies can be combined according to the packaging design.

Why Add a UV Flatbed Printer to a Traditional Printing Plant?
Adding a UV flatbed printer does not mean replacing conventional printing equipment.
Traditional printing can continue to handle:
- Simple artwork with basic color requirements
- Cost-sensitive packaging
- High-volume products
UV digital printing can be used for:
- Packaging requiring stronger color performance
- Product images that need higher visual quality
- Gradients and complex graphics
- Premium brand packaging
- Customized, higher-value gift boxes
The two technologies can therefore serve different product positioning.
Standard products can focus on volume, while higher-quality products can create greater added value through better visual presentation.
For packaging manufacturers that already have conventional printing equipment, a UV flatbed printer provides more than another printing method. It creates an additional route into higher-quality packaging applications.

Baosiwei UV Printing Solution for Kraft Paper
The Baosiwei JW-2513UV flatbed printer is designed for rigid and sheet-material printing. It can be configured with 2–8 Ricoh G6 industrial printheads and supports printing resolutions of up to 1200 dpi.
For kraft paper packaging, the printer can use white ink underprinting followed by CMYK color printing, with different designs switched directly through digital files.
The 2500 × 1300 mm printing platform supports different sheet sizes and formats.
In addition to kraft paperboard and packaging board, the JW-2513UV can also be used for materials such as wood, acrylic, and PVC.
For packaging manufacturers that already have conventional printing lines but want to improve kraft paper packaging quality and develop higher-value products, UV flatbed printing can be a practical addition to the existing production system.
