When using the Gray_Curve
function with the format xx;yy is the first number my derived value
(densitometer reading) or my target value?
If I used Gray_Curve and then did a second print using the same data in Linearize, would the resulting print be identical?
First, the convention with the curve is that the first number is input, the second output.

Thanks to Roy for clarifying the use of the LINEARIZE command as it involves entry of direct readings from a reflection densitometer. I had totally missed out on that feature.
So, having previously linearized a QTR profile with lab values using a spetrophotometer I repeated the process using density readings from a reflection densitometer. The values for the two methods are entered as follows.
LINEARIZE=“1.61 1.48 1.34 1.25 1.12 1.01 .90 .81 .70 .64 .58 .51 .45 .37 .31 .26 .20 .12 .04 .02 .00”
LINEARIZE="19.09 22.43 25.75 28.72 32.3 36.17 40.41 44.33 49 52.02 54.97 58.86 62.44 67.34 70.83 74.74 79.49 84.23 91.24 94.15 95.15"
The two methods do not produce identical correction curves, though they are close.
