Laser imaging principle of Kodak CTP

Kodak CTP uses LDD bars of different power, shaped and focused by optics, to form square laser spots of 10.6 × 3 μm per pixel. The performance parameters for different laser models are illustrated below.

Three repair scenarios

A. Laser diode / LDD replacement (OEM parts preferred)

Symptoms: power drop, failure, slower production speed.

B. Light valve and focus optical path abnormal / failed

Symptoms: white lines on plates, light balance failure, abnormal energy, focus drift failures.

C. Control board / power / board-level repair

Symptoms: error reports, protection, no laser, safety loop or communication faults.
