Flexo print support: tesa® Softprint troubleshooting
This library shows a collection of major print issues that our experts regularly come across and how to tackle them.
Plate edge lifting occurs when a mounted plate lifts from the sleeve.
Watch this troubleshooting guide to learn:
- How to identify key causes, from improper plate preparation to worn sleeves.
- Actionable solutions and prevention techniques.
- How tesa® Softprint technology provides a secure, reliable bond.
Pinholing occurs when ink fails to form a continuous film, leaving tiny unprinted voids in solid print areas.
Watch this troubleshooting guide to learn:
- How to identify key causes, from insufficient pressure to incorrect ink viscosity and anilox status.
- Actionable chemistry and press-side adjustments.
- How tesa® Softprint tape solutions help ensure solid density and even ink transfer.
Air collection leads to bubbles forming either between the sleeve and tape, or between tape and plate. No matter where, trapped air will show in print defects.
Watch this troubleshooting guide to learn:
- How to identify key causes, from incorrect mounting technique to dirty sleeve surfaces.
- Actionable solutions and prevention techniques.
- How tesa® Softprint technology provides bubble-free mounting.
Ghosting occurs when the ink chamber fails to fully refill anilox cells, leading to faint replica images appearing within solid print areas.
Watch this troubleshooting guide to learn:
- How to identify key causes, from deep anilox cell geometry to low ink pressure.
- Actionable mechanical adjustments and component installations
- How tesa® Softprint contributes to a stable process chain that prevents ink depletion.
Bouncing is characterized by bands across the machine direction of the print, often caused by mechanical resonance or gear wear.
Watch this troubleshooting guide to learn:
- How to identify key causes, from incorrect cylinder circumference to press speed.
- Actionable mechanical solutions and maintenance techniques.
- How tesa® Softprint foam hardness levels dampen vibration and increase press uptime.
Excessive dot expansion causes dark, muddy prints and lost detail. Balance your parameters for perfect ink transfer and sharp resolution.
Watch this troubleshooting guide to learn:
- How to identify key causes, from excessive impression pressure to incorrect ink viscosity.
- Actionable process adjustments and maintenance techniques.
- How tesa® Softprint foam hardness levels prevent dot gain while maintaining secure mounting.
Trailing edge void (TEV) is localized ink starvation that occurs exclusively on the back edge of solid motifs.
Watch this troubleshooting guide to learn:
- How to understand the "ink splitting" physics and negative pressure that cause TEV.
- Actionable solutions, focusing on foam hardness selection and plate surface micro-screening.
- How tesa® Softprint technology provides stable edge separation.
