Digital BW, The Print

Hi Joe

Unfortunately I'm not reading in density values but instead using L 
values. With the aims slider set to 0 I get a nice straight line 
match between aims and readings. However this prints too dark. If I 
set the aims to -4, step 13 remaps from 50 to 40 and the aims 
straight line becomes a curve. The test image now prints lighter and 
is a better match with the monitor. However is this good practise?

How would you lighten a perfectly good profile ?

Peter.
