QTR-Quadtone RIP

Am giving this a go using the Quad 3800 printer
Have printed the initial inkseparation curve and found that

85% K = 2.31
90% K = 2.36
95% K = 2.43
100% K = 2.46

This suggests to me that the default ink limit in the curve creator remains at 100% as the density is continuing to increase right upto 100%

Using Han Photo Rag Baryta 315 paper

Have I discovered that the 3880 lays down less ink and the density may carry on going up

Using a i1Pro + Measure tool

Thanks
