Coating color:     Blue

 

Spectral Sensitivity:    780 - 850nm

 

Exposure Energy Required: 120 mJ/cm2 – 150 mJ/cm2 (dependent on imager type, configuration and resolution) 

Resolution:           1% to 99% @ 400 Ipi or 10 micron stochastic (dependent upon capability of imaging device) Developer:   DV-T Series Developer

Run Length:        400,000 impressions unbaked, 100,000 impressions for UV ink applications, 1,000,000 plus impressions baked

 

Safelight:  Daylight Handling

 

Shelflife:   12 months under recommended storage conditions

We recommend a processor technician to adjust the unit to its specified condition for optimum plate performance.

 


Plate Handling

Safe-Light

Plates can be handled before and after imaging in white light.

 

Plate Handling

Imaged plates must be stored face to face with interleaf sheet between the plates.

 

Proper storage

Room Temperature conditions.

As with all CTP plates, it is recommended that both raw and imaged plates be handled with gloves and be stored with interleaving slip-sheets to prevent fingerprinting and scratching.
