**How to Control Color Difference in Printed Bags?** 🎨

Design looks great. But when it's printed—color shifts. How do you fix that?

It comes down to **4 key points**:

**1. Use Data, Not Eyes** 📊

Eyes see color differently. Physical color charts fade.

👉 Use a spectrophotometer. Keep **ΔE ≤ 3** (human eye can't tell the difference)

**2. Ink Management – No "Eyeballing"** 🧪

Viscosity changes = color changes.

👉 Automatic viscosity control. Spot colors mixed by formula, not "add a little"

**3. Workshop Environment – Stable Temp & Humidity** 🌡️

Temperature changes = ink viscosity changes = color changes.

👉 Constant temperature & humidity. Pre-heat ink in winter

**4. Inline Monitoring – Don't Wait Until It's Too Late** ⚙️

If you catch the problem after the run, it's waste.
