Re: [Digital BW] QTR paper settings for Esemimatte or prem luster

2005-02-03 by Steve Kale

Try the Ilford Smooth.

But it is worth understanding what a QTR curve is a little more because (you
have a great printer and) ideally you would have a curve linearised for that
specific paper (and your specific printer).  Take a look at one of the ink
descriptor files (.txt) and then look at its .quad file.  The .txt file is
how you instruct QTR to create a set of lookup tables - the .quad file - for
a specific ink/paper combo.   In essence, QTR for each file pixel value
looks up the tables and fires each ink according to the % indicated in the
lookup table (expressed as an 8 bit number).  When you do an ink descriptor
file you tell QTR which inks are going to be used to make up the greyscale
(eg K and LK combined with LM and LC to cool the LK down =>
UC_Neutraliser=yes), what the ink limits are and at what point are the
cross-overs, and importantly, at the end you linearise this, meaning you
want nice even steps in Lab's luminance from paper white to ink black.
Combine this nicely linearized greyscale output with Roy's perceptual
rendering and you have a sweet workflow.
