5 Common Printing Ink Problems (And How ZxSubian Solves Them)

Introduction

Printing ink issues can cause costly production delays, product defects, and customer complaints. From poor adhesion to color fading, these problems are a constant challenge for packaging manufacturers. At Subian Factory, we’ve helped hundreds of clients resolve ink-related issues, and in this blog, we’ll share the 5 most common problems and our proven solutions.

1. Poor Adhesion to Plastic Films

Problem: Ink peels or scratches off the film surface, leading to defective packaging.

Cause: Incorrect ink formulation for the substrate, insufficient surface treatment, or improper drying.

Subian Solution: We formulate inks specifically for your plastic film type (BOPP, PET, PA, etc.) with enhanced adhesion promoters. Our technical team also provides on-site support to optimize surface treatment and drying processes for maximum bond strength.

2. Color Inconsistency Between Batches

Problem: Print color varies between production runs, damaging brand consistency.

Cause: Inconsistent raw material quality, poor formulation control, or inadequate quality testing.

Subian Solution: We use strict raw material sourcing and batch testing protocols, with advanced color matching technology to ensure ±ΔE ≤ 1.0 color consistency across all batches. Our clients receive detailed color reports for every order, guaranteeing brand color accuracy.

3. Ink Blocking During Lamination

Problem: Ink transfers between film layers during lamination, ruining the final product.

Cause: Insufficient ink drying, incompatible ink and adhesive systems, or high production temperatures.

Subian Solution: Our composite inks are formulated with fast-drying, lamination-compatible resins that prevent blocking. We also provide adhesive compatibility testing and process optimization to ensure seamless lamination performance.

4. Poor Resistance to Sterilization/Extreme Conditions

Problem: Ink fades, blisters, or delaminates after retort sterilization, freezing, or oil exposure.

Cause: Ink not formulated for the end-use environment.

Subian Solution: Our Z Series retort-resistant inks are tested to withstand 135°C sterilization, extreme cold, and chemical exposure. We customize formulations for your specific end-use requirements, ensuring long-term performance in any environment.

5. High VOC Emissions and Environmental Non-Compliance

Problem: Ink emissions exceed regulatory limits, leading to fines and production shutdowns.

Cause: Traditional high-VOC solvent-based inks.

Subian Solution: We offer a full range of low-VOC, water-based, and bio-based inks that meet global environmental standards. Our team helps clients transition to sustainable ink systems, reducing emissions and ensuring compliance without sacrificing print quality.
