The Hidden Cost of Hazing: Why Low-Contrast Defects Demand Early Detection
23 May 2025

In industrial printing, not all defects shout. Some whisper — subtly dulling colors, softening images, and undermining brand perception without ever triggering a press alarm. One of the most overlooked yet costly of these silent offenders is hazing.
Hazing appears as a cloudy or misty veil across printed surfaces, often diminishing image sharpness and causing critical areas — like graphics, text, or color blocks — to appear washed out or low in contrast. While not always immediately visible to the naked eye on-press, hazing can be glaring under shelf lighting or in side-by-side comparisons with brand standards. The result? Disappointed customers, rejected batches, and brand owners questioning quality control.
What Causes Hazing — And Why It Matters
Hazing typically stems from one or more root issues:
- Ink formulation or transfer problems, especially in flexo or gravure printing
- Improper or inconsistent drying, leading to solvent retention
- Contamination on the substrate or plates
- Worn anilox rolls, leading to uneven ink laydown
- Poorly calibrated color or tone curves, reducing contrast in subtle areas
Because hazing doesn’t always appear as a sharp, defined defect, it often flies under the radar during press runs — especially when operators are monitoring at speed or working without automated inspection systems.
But hazing has real consequences: weakened branding, diminished readability (especially for small text or barcodes), and failed color targets that result in rework, waste, or even regulatory issues. For converters producing high-end packaging or brand-critical materials, these subtle flaws can be deal-breakers.
Making the Invisible Visible — with AVT
At AVT, we specialize in catching the defects others miss.
Our print inspection systems are designed to recognize low-contrast anomalies like hazing and tone shift in real time. Using high-resolution line scan cameras and advanced image processing algorithms, AVT solutions continuously compare the live print against a golden reference — pixel by pixel — detecting even subtle inconsistencies in background areas, gradients, and overprints.
But detection is only the beginning.
With AVT, you gain insights and control across the entire print process:
- Color control & consistency: Real-time ΔE monitoring ensures brand color accuracy — even when haze softens visual perception.
- Ink & anilox monitoring: Spot issues like clogged anilox cells or over-inking before they lead to hazy prints.
- Registration verification: Misregistration can contribute to ghosting or blur — our systems catch this instantly.
- Data reporting & traceability: Every job is tracked and documented, enabling root cause analysis and quality audits.
- Real-time alerts & workflow integration: Press operators get immediate feedback, enabling quick corrections and minimizing waste.
Whether you’re printing shrink sleeves, flexible packaging, or labels, AVT empowers your team to deliver clean, crisp, and brand-accurate results — every time.
