Hello everyone,
My question is: What are your tolerances for plate readings?
We output a step wedge on all plates and measure every plate, charting the readings for reference. We have a Fuji Saber using the new LP-NV2 plates. Obviously some jobs are more critical than others, so we aren't critical on type only jobs or spot color jobs, but process jobs and repeat jobs we watch and keep within tolerance.
Here is what is on our step wedge and our tolerances.
2% +- .5%
5% +- 1%
10% +- 1%
20% +- 1.5%
30% +- 1.5%
40% +- 2%
50% +- 2%
60% +- 2%
70% +- 2%
80% +- 2%
90% +- 1.5%
95% +- 1%
97% +- 1%
With the violet plates they seem to be consistent for a while then all of a sudden there is a shift. It could be chemistry, although we change the chemistry about every 300 plate, or it could be something else like humidity.
Let me know what you think is acceptable.
Thanks!
Mike
