Preset Curve Adjustment

 

The P3500 offers two methods of adjusting the preset curve for any fountain: Percent Multiplier and Self Learning.

 

Percent Multiplier  - A percent multiplier is applied for a uniform offset to accommodate eleven different paper stock types.

 

Self Learning Feature  - A self-learning feature is used to evaluate and refine preset accuracy; a comparison of the digital file values for preset are compared to the file containing the settings of a job from color-OK to save. The self-correcting feature makes automatic corrections to compensate for variations between the preset file and the color OK. The algorithm uses the previous six jobs for analysis.

 

 

Viewing Data

 

The P3500  allows viewing of ink key settings in both graphical and numerical formats. To view an image of a particular plate, you simply select the desired plate number from the Job Setup dialog box.
