If a multilayer job lines up in the center but shifts more toward the edges, the PDF may need to be rendered with Fine Line Rendering enabled. This setting can improve registration when layers are processed separately and then combined.
Symptoms
- Color and white layers align correctly, but an additional color layer shifts.
- The shift is minimal in the center and becomes more visible toward the edges of the roll or sheet.
- In 3-layer jobs, each additional layer may appear slightly more offset than the previous one.
Cause
In some PDF workflows, affected elements are not rendered using a consistent geometric reference across separate layer renders. This can lead to visible registration drift when the layers are combined in output.
Resolution
- Enable Fine Line Rendering for a single file:
In FileMan, open Setup > RIP Parameters and enable Fine Line Rendering. - Or enable it globally:
In the RIP interface, open Configuration, go to Adobe PDF Print Engine Options, and enable Force Fine Line Rendering. - Re-rip the job after changing the setting.
- Check registration again across the full print width, especially near the edges.
When to use this setting
This setting is recommended when accurate alignment between multiple PDF layers is critical, especially if files are rendered separately before being combined in a multilayer print workflow.
