QTR-Quadtone RIP

I'm new to QuadTone and the X-Rite Pulse system. I finally found using 
Colorshop X in the Color Scratchpad was a way to to pull up an L* value 
by individual readings for the 21step wedge for linearization. The 
values as the Pulse gives me in L* are for the lightest patch 96.76 and 
the darkest 16.11. These values are numerically different than those 
required for placing the linearization values. Is there a conversion 
table I need to use or is there a different way to pull up the L* 
numbers with the Pulse? Thanks.

I used the colorshop x color scratchpad lab values with the pulse to measure the 21 step wedge.  there is no need to do any conversion.  the lab values are fine as they are for linearization in qtr.  make sure you do it in the proper order.  if i remember correctly it is from light to dark.

Hi Roman

entering L values in the Linearization section of the curve creation 
in QTR works fine for me, as the help file explains, start from the 
highest value first (in your case: 96.76) and work down. Initially, 
save your readings as a text file or as an excel file and use the 
copy and paste facility. I tend to save all the Lab values, so I can 
see what the a and b values are doing (via a simple excel graph.)

Since you have a Pulse you might like to have a look at 2 free 
downloads from the X-Rite website, they are: Colorport and 
XKey/Toolcrib, I use these to great effect with the Pulse,

good luck, Jamie.

Hey Jamie,

Thank you for the ideas. It appears I'm in your dust trail just 
trying to keep up. I did download both ToolCrib and XKey and I'm 
having some luck having them talk to each other, but can't seem to 
get the values into Excel. The numbers seem to be strangely coded in 
ToolCrib. Is there something I should do to snap Excel into accepting 
the values? Any hints to have each talk to each other would help.

All the best,

Roman
