QTR-Quadtone RIP

I'm trying again to create my own Ink Pattern Page [the page printed
when in calibration mode] which I intend to read with an X-Rite Pulse 
(DTP20) in one straight swoop, instead of the individual spot readings 
I'm currently having to take, one at a time, very slow and painful.

Question:

I'm going to use a fine little program called ColorPort to produce the 
Target, I just need a pointer as to the figures I should use in the 
target production. Should I just open an original QTR Ink Pattern Page 
in Photoshop and manually read the RGB values (which is what I need) 
or does someone have the values recorded somewhere.

Even better would be if someone has already created some Ink Pattern
Pages for the X-Rite Pulse,

The ones I made for the SpectroCam may be usable for you. Only 
the linearisation/profiling targets. So I didn't do the ink 
limiting, curve creation targets as I find it easy enough to 
do it per patch on the maybe 20 patches scattered over that 
target.

I'm thinking of an improvement on the random 
linearisation/profiling target to keep errors down in strip 
reading, the contrasts between patches isn't always high 
enough for my SpectroCam to switch to the next patch.


Met vriendelijke groeten,  Ernst

Have a look at the file section. Some month ago I uploaded such a target.

Thank you Ernst and Winfried

I've referred to both of your work/files before I started this 
little project, and they were both very helpful and led to success 
in scanning the 21 step wedge with my Pulse setup.

Now I want to try and go 1 step further and try to scan the Ink 
limiting/curve creation targets in calibration mode with my Pulse 
setup. At the moment I do as you do Ernst and spot scan a random 
number of patch's which visually look close to the Ink Limits, but 
being able to scan all patchs in 1 swoop would be good use of my 
equipment and would enable me to monitor suppliers ink formulations 
for any variance and also keep an eye on the paper suppliers 
coatings, again for any variance in production batchs.

Jamie.

First, QTR targets are "weird". Only two of the three colors are
actually used. If memory serves, the red channel is the density,
0-255. (you can check this easily in PhotoShop). I think the blue
channel is the "ink selector". The selector is binary...

1 = ink 1
2 = ink 2
4 = ink 3
8 = ink 4
16 = ink 5
32 = ink 6
64 = ink 7
128 = ink 8

If you want to do something like having equal parts of two inks, turn
two channels on at the same time by adding their numbers.

The big question, are you using cyan, magenta, yellow, and black inks,
or a pure monochrome set? The Pulse reads a strip at the top of the
chart called the "Target ID", or TID, that's in an octal (base 8) code
of cyan, magenta, and yellow. The TID tells the pulse how many patches
there are in each row, and on the chart, in total. The "Row ID" at the
beginning of each row identifies the row number. The TID and RID need
to be in the right colors. If you're using color inks, use a density
of 128 and use the selectors to get the proper CMYKRGBW codes. You
can't print them TID or RID with monochrome inks. So if you're using a
monochrome inkset, you need to print a TID and RID on a color printer,
at the proper size, and glue it over the monochrome chart.

Or make a chart for the color printer with just a TID and RID, no
patches, and a chart for the monochrome printer with just patches, no
TID or RID, and run the paper through both printers. Frankly, I find
cutouts easier.

Ciao!

Joe

Cheers Joe

you've just confirmed what I arrived at earlier this week. I have 
now produced the Ink Seperation Page for use with an X-Rite Pulse. I 
use Colorport to produce the target, then I seperated the target 
into 2 parts; firstly, the TID which I printout on a colour printer; 
and secondly, the ink seperation patches (6 x 21 step wedges) for 
use by QTR with my monochrome ink printer. Now I can read all the 
patches of the Ink Seperation Page in less than a minute, and enjoy 
the privilage of looking at the Lab values of the inks before I 
start creating curves. Also thanks to Winfried I also enjoy reading 
my various 21 step curve iterations in doule quick time. Again, 
thanks for your reply,

Jamie.

Where can I download this ink seperation page?

Hi Leen

if you drop me an email, I'll be able to get my ink seperation page 
to you, along with some useful tips on how to use it. Are you aware 
that you need a second colour printer inorder to print out the TID 
and RID strips before printing the seperation page from within QTR, 
and it's rather intricate since you need to create a target via 
colorport, but it can be done. For most people I would imagine it is 
all to much trouble, and I would agree, but It suits me just fine as 
I'm interested to see what each ink is made up of in terms of Lab a 
and b (and how the values drift over time.) Anyway, enough of my 
ranting; if you want me to help you to try and do it yourself, just 
get in touch,

Jamie
