Product Overview
Our Surface Digital Printing Equipment is a high-efficiency,
eco-friendly direct-to-object printing system specifically
engineered for high-quality surface decoration on molded pulp
products, including food containers (clamshells, trays, bowls,
cups), seedling pots, and industrial protective packaging.
Utilizing advanced single-pass piezo inkjet printhead technology
and a fully customizable UV-curable or water-based ink delivery
system, the machine applies vibrant, scratch-resistant graphics,
logos, variable data (barcodes, QR codes, serial numbers), and text
directly onto the complex, often irregular surfaces of pulp molded
products.
Key Advantages
- High-Speed Single-Pass Printing: Up to 60 meters/minute (depending on resolution) for maximum
production throughput
- Exceptional Print Quality: Up to 600×600 dpi standard, configurable with customizable
printhead arrays for higher resolutions on detailed graphics or
fine text
- Superior Adhesion: Advanced UV-curable and water-based ink systems engineered for
porous, textured fiber surfaces, with optional pre-treatment for
optimized bonding
- Multi-Surface Capability: Supports printing on flat, curved, convex, and deeply recessed 3D
surfaces, making it ideal for decorative branding of sustainable
pulp packaging
- Zero Platemaking / Fast Setup: Eliminates plate costs and makes short runs, one-off samples, and
variable data economically feasible for even the smallest batch
sizes
The system is fully customizable to match unique product shapes,
packaging formats, ink types, and factory floorplans.

Frequently Asked Questions
Q1: Can the printer handle irregularly shaped 3D products (bowls,
trays, egg crates) with raised textures?
A: Yes. Our digital printing system is specifically designed for
direct-to-object printing on complex fiber surfaces. The
customizable fixture systems securely hold each product type, while
the printhead and UV curing module adjust for varying profiles and
textured topologies.
Q2: What are the main ink options? Is it food-safe?
A: We offer two primary customizable ink platforms: UV-curable inks
for instant curing and highest adhesion on rough pulp; water-based
food-compliant inks for full compostability and direct food-contact
safety. Both types are low-VOC and engineered for fiber-based
packaging.
Q3: How fast is the printing speed?
A: The machine can operate at speeds customizable from lab-use 1
m/min up to industrial 50-60 m/min (higher rates possible for lower
dpi requirements), keeping pace with modern pulp molding production
lines. Variable data printing (barcodes, serial numbers) does not
degrade line speed.
Q4: How does the system overcome the natural irregularity of molded
fiber surfaces?
A: Our customizable combination of servo-driven belt conveyors,
precision fixturing, and optional CCD vision registration ensures
that each product is accurately positioned relative to the print
head. Additional ink-adhesion pre-treatment modules (plasma/corona)
are available for difficult surfaces.
