UV Printing on Leather: Process and Printing Workflow
UV Print on leather is primarily divided into two process flows based on the leather’s base color: direct UV printing on white/light-colored leather and direct uv inkjet printer on dark-colored leather. The printing steps differ slightly for each base color to ensure optimal color reproduction and durability of the patterns.
Direct UV Printing Process for White (Light-Colored) Leather
White or light-colored leather surfaces offer high color fidelity for patterns, allowing direct full-color printing.
UV Printing on leather process is as follows:
Leather Fixation and Surface Preparation
Secure the white leather flat on the head uv printer 6090 work surface, ensuring it is clean and free of dust or grease.
Direct Color Pattern Printing
Use the uv 6090 printer to print the full-color pattern directly onto the white leather surface without requiring a white ink base layer.
Varnish Reinforcement (Optional)
If the customer requires higher abrasion resistance, adhesion, or longevity for the design, after completing the color printing.
Apply an additional layer of varnish using the uv prints.
To enhance the design’s scratch resistance, wear resistance, and overall durability.
Dark Leather UV Direct-to-Leather Printing Process
The printing process is as follows:
Leather Fixation and Positioning
Secure the dark leather onto the UV printing services platform, adjusting print height and positioning.
White Ink Base Layer
Apply a layer of UV white ink across the designated printing area to enhance color vibrancy for subsequent patterns.
Color Pattern uv sticker printer
Print the color pattern over the white base layer to achieve vibrant hues and clear tonal gradation.
Varnish Reinforcement (Optional)
For customers requiring enhanced pattern durability and longevity.
Apply a layer of UV varnish after pattern printing.
To significantly improve abrasion resistance and service life.

Common Issues and Solutions for Leather UV Printer: Preventing Cracking
When Leather UV Printer or soft materials, especially during autumn and winter, issues like cracking, peeling, or white lines appearing at bends may occur. The primary causes and solutions are as follows:
Inappropriate Ink Type
Standard rigid UV inks cannot accommodate the flexibility and stretch characteristics of leather.
Solution: Use specialized UV flexible inks or latex inks to ensure pattern integrity during bending, stretching, or thermal testing.
Environmental Factors
Excessively low indoor temperatures and insufficient humidity accelerate cracking.
Recommend maintaining a printing environment of 20–28°C (68–82°F) with 55%–65% humidity to ensure uniform ink curing.
Equipment Curing Parameters
Excessive or insufficient curing lamp power compromises ink adhesion and flexibility.
Adjust lamp power based on leather material and ink properties to achieve stretchable prints.
Material Selection
Soft, stretchable leather (e.g., TPU leather) printed with UV flexible ink can withstand bending and rubbing without cracking.
Key Tips Summary:
Select specialized UV flexible ink or latex ink
Control printing environment temperature and humidity
Adjust UV curing lamp power
Optimize printing solutions based on leather characteristics
