The Three Most Common Copper Surface Defects—and How to Prevent Them   70% of defects in rotogravure cylinder production from issues during plating and surface finishing process. These defects can compromise engraving quality, increase costs, and lead to production delays.   Here are the three most common defects, their root causes, and how Q-trac helps you eliminate them:   1️⃣ PIMPLES: Occur due to surface contamination (e.g., dust, oil, grease), impurities during copper plating, residue from improper polishing, or soft, porous copper caused by incorrect plating  conditions. 2️⃣ HOLES: Caused by contaminated copper plating tanks , low copper ion concentration, poor cleaning or preparation (e.g., oxidized copper, dust), overheating during polishing, or environmental factors like high humidity or worn equipment. 3️⃣ SCRATCHES: Result from hard particles or improper cleaning tools, metal chips or incorrect pressure during polishing, inadequate cooling, dusty environments, operator errors, or mishandling during transportation or lifting.   Here’s why acting early matters: ➡️ Defects transfer directly during engraving, creating repeated, visible issues on the final print job. ➡️ Even non-engraved areas can cause smears, streaks, or unwanted ink transfer, leading to customer complaints. ➡️ Fixing defects after engraving requires re-polishing and re-engraving, which is time-consuming and expensive.   How Q-trac helps to prevent defects: ✅ Automatically detects and pre categorizes pimples, holes and scratches  on scanned cylinders with unmatched precision, as shown in its detailed defect maps. ✅ In Q-trac, the pre-categorized errors can be reviewed and grouped into “Rejects”, “OK”, or “Rework ✅ Defects are displayed in the defect list and automatically transferred to the CYON Cylinder Database. Q-trac is an intelligent, fully automated quality inspection system specifically designed for rotogravure cylinder production. It detects surface defects on non-engraved copper surfaces and measures critical quality parameters with exceptional accuracy.   With Q-trac, you can achieve unmatched quality and efficiency in rotogravure cylinder production.   Want to learn more?
