QTR-Quadtone RIP

I'm trying to make ICC profiles using QTR-Create-ICC for use with ABW on my 3800.

Using Spyder3Print to measure, all goes well using a 21 step wedge, so I tried the 21x4 
random patch file, hoping to build a better profile. I got the error message

<The Lab values are not in order. Cannot make a profile.>

Thinking I sent a bad format to QTR-Create-ICC, I tried the sample supplied with QTR, 
named QTR-21x4-random, and got the same error message!

I got the same results sending to QTR-Linearize-Data. And with the QTR-51-random 
sample file.

What am I doing wrong that I can't even get the sample files to work?

Michael

Hi,
How do you use the Spyder to measure a wedge? I couldn't find any
reference.
Thanks in advance,
Jean

I also use a Spyder for reading the step scales and have found there is a straight forward 
approach that builds a text file that can be drop onto the create applett.

When Spyder Print 3 is at the opening screen, the TOOLS menu has a calibrate option 
avialable, clicking on that and calibrating the spectrometer then activates the "Measure" 
option, clicking on that opens a window that permits reading the target. Then it saves to a  
text file that can be dropped on the applett.

Can anyone tell me the difference between PrintFixPro 2.1 (the upgrade I loaded recently) and Spyder3Print? 

Is it a newer better version?  The Spectrocolorimeter appears to be Datacolor 1005 in both cases.

Thanks
Jim

It seems to be a software upgrade and definitely does use the same spectro.
There must be some internal improvements because Colorvision/Datacolor keep
recommending anyone mentioning PrintFixPro to upgrade.

Tom Moore

Jim,
Spyder3Print is the new name for PrintFixPro and there is a latest
version on the download page of Datacolor. Your old serial number
remains valid but must be entered after installation. Old settings
remain valid throughout the update. New version allows measuring of
wedges and preparing files which can be read into the QTR-Create-ICC
program. Highly recommended.

Just the interface has been updated to Spyder3Print, no internal changes to the code.

Sorry to disagree, code has changed:
/*********** quote from email:
All existing PrintFIX PRO users can download and install the latest
(newly renamed) version of the software, Spyder3Print 3.0. You can
download the installer from the Support:Software Updates download
page; just look for a single line near the middle of the page. It has
download links for both the OSX and Windows versions, and also, click
on the "i" link at the end of the line to see the Update Notes (please
read these to see what the new features are, and also about how to
install and how to copy over your older measurement files).

Spyder3Print 3.0 can be initialized with your existing PrintFIX PRO
serial number, and there are no changes in the Targets or the
measurement file format, so it's completely backward compatible with
everything you've already done.

I'm the originator of this thread, which has generated discussion about Spyder3Print. 
However, my question has never been addressed.

I'll rephrase. Has anyone successfully used one of the random step wedges to linearize or 
make an ICC profile by dropping the file obtained from reading the patches on QTR-
Linearize-Data or QTR-Create-ICC? On a Mac?

I'm unable to get even the supplied sample files (e.g., QTR-51-random) to work. I get the 
message "Lab values not in order. Cannot Linearize" (or "Cannot Create ICC").

Help!

Michael

Michael,

I always use the 21 step random target for linearizing in QTR and it 
works just fine.  The only time I have had problems was when shadow 
values were so close and bunched up that QTR decided they were too 
close.  If there are reversals, then it definitely bombs.  The 
solution in that case is to change the parameters and get more 
separation between shadow steps before trying to linearize.  That can 
be done in a number of ways.  

I felt that the 51 step wedge had too many steps for linearization 
and would probably make it even harder to get data that didn't have 
crossovers.  So, I always used the 21 step random file.  I use an 
EyeOne, but that shouldn't make any difference.  

If you get that error message when trying to linearize using the 
droplets, the I suspect your values are too close together at some 
point in the tonal scale.  

Hope this helps.

Lou

Michael, Lou,
I just installed the update to Spyder3print and only spent one evening
trying to get the right tone for my R1800. I have seen that the
QTR-program refuses to linearise when either some values increase
instead of decrease or, as Lou points out, the values of 80-85-90-95
and 100% are to close so that the curve flattens. A good help is
entering the data from QTR (or directly from your readings) in a
spreadsheet and then let it draw a graph. You will immediately see if
there are values out of order or if the tail of the curve platforms.
This is a problem I have wher my values for 80 .. 100% are 30.25 28.72
27.5 27.43 27.36. You see that there is little difference and I think
I might have to limit the amount of ink to below 70%.
Lou, to assure you the program doesn't bomb.
Regards to all,
Jean

How about this.... the code was not changed to build better profiles? 8-}   Not that it's 
needed...

Hello Michael,
I get the same error message with the supplied sample files. I've also
been unable to convert a file exported from PrintFix Pro. I'm on a Mac
running OS 10.5.1 Leopard, using QTR 2.5.2 with the Leopard patch.

Looking at what I called the "Sample" files, I see that they are not in the same format as 
the files from my reading of the 21 step not-random step wedge. One file I used 
successfully with Spyder3Print looks like this:

BEGIN_DATA_FORMAT
SampleID	GRAY	LAB_L	LAB_A	LAB_B
END_DATA_FORMAT
NUMBER_OF_SETS	21
BEGIN_DATA
1	0	93.47	0.95	-5.24
2	5	90.32	1.05	-4.97
3	10	86.37	1.01	-4.67
4	15	82.67	0.85	-4.43
5	20	78.93	0.84	-3.94
6	25	75.11	1.23	-3.45
7	30	70.66	1.01	-3.77
8	35	66.64	0.68	-3.38
9	40	62.66	0.84	-2.49
10	45	59.03	0.85	-2.39
11	50	54.67	1.05	-2.55
12	55	50.07	0.99	-2.01
13	60	45.20	1.29	-1.51
14	65	40.02	1.14	-0.99
15	70	35.31	0.97	-0.97
16	75	29.48	0.88	-0.28
17	80	23.68	0.83	0.04
18	85	17.52	0.65	0.39
19	90	12.26	0.45	0.71
20	95	7.17	0.11	1.50
21	100	2.26	0.00	0.24
END_DATA

I hope the formatting shows properly.

Here's what I did to make that file from the 21 step not-random printout:

In Spyder3Print, under Tools:

First, do the Calibration using their supplied white target.

To make a file for icc profiling, go to Tools/Measurement

1. set a name for the export file. I prefix mine with my initials, MR, so I can tell the ones 
I've made from the many other profiles that show up in Photoshop drop downs. QTR will 
also put its prefix in front, as it does with profiles supplied with QTR (as QTR - Grey Matte 
Paper) so mine end up as QTR_MRxxxx.

2. check QTR Override and press 'CreateICC'

3. make measurements

4. Press Done

5. Drop the file in the Spyder3Print 3.0/Data/Export folder on the QTR-Create-ICC 
droplet

6. Move the created .icc file to ~/Library/ColorSync/Profiles or to another Profiles folder.

Mac, Tiger. QTR 2.4.3. Hope that helps.

Michael

Thank you Lou and Jean for telling me that the 21 step random file can work and 
presenting your caveats. I will tinker and will get it done.

Looking at what I called the "Sample" files, I see that they are not in the same format as 
the files from my successful reading of the 21 step not-random step wedge. So I'm not 
sure what they're samples of.

Lou, FYI, the latest 2.5 Eye-One Read Me pdf says, "The 21x4 target is recommended for 
the best accuracy. I has 4 patches for each step value and the QTR software will 
automatically average the 4 measurements which gives a more accurate result." 

Thanks again.
Michael

Forgive me if this has been convered; I did not peruse
the entire thread. 
The QTR-Linearize-Data/QTR-Create-ICC will only work
(in my experience) on LAB data, exported from Gretag
Macbeth Measure Tool.
Again; I am sorry if that issue was put to bed...

I have made numerous ICC and curves using data read by the ColorVision spectrometer 
using Spyder Print 3 for reading the files. I use the 21 step times 4 random image for 
reading the data. It is important that the data be read vertically from left to right. That is, 
Col 30 top to bottom, then Col 70 top to bottom, then Col 5 etc to end of image on the 
right.

Here is what the resulting text file looks like:

I realize that cutting and pasting the text files into this message makes it long but 
hopefully it also makes it more clear.

This is being done using the Leopard patched version of QTR on a MacBook Pro running 
Leopard 10.5.1.

David,

Thank you!!

The mystery is solved. I find that what's required to use the 21x4 random patches are

1. Version 2.5 of Create-ICC  (I used 2.5.1.0). My 2.4.3 version doesn't work for the 
random patches with any file format I've tried. Note that the date/time stamp is the same, 
but the program size is different; 2.5 is a different program from 2.4.

2. A tab delimited file, like the one in David's post. Playing with Spyder3Print, I checked 
"QTR Format Override" and "CreateICC" which gives a different format that happens to 
work with the not random 21 step file. In Spyder3Print, checking "Lab" and "Include Line 
Numbers" produces a tab delimited file that looks like the one David posted and works. 
The Eye One's options and defaults are surely different.

Also, I have found that it doesn't matter whether the patches are read down-then-across 
or across-then-down.

Michael,
thanks for clarifiying about the order in which the samples are to be read.
There is a file (QTR-21X4-Random) in the EyeOne folder that shows the A1-4 then B1-4 
order. That is what I based my comment on, so its good to know that either way works. 

I'm also glad that the other information was useful. It's nice to have repaid a bit of the 
help I've received via this and other photography fora.

David
