PrintFixPro 2
I read the message about "Show Edits in Preview" box.


My prints are good and are similar to my screen. But the soft proof is
not contrasted as if there were a veil.
How may I change the rendering of the soft proof?
If the "Show Edits in Preview" box is checked, print and soft proof
are affected.
If the "Show Edits in Preview" box is checked, print is affected and
soft proof is not affected.
What is the trid solution?

Another issue:
- if I use the calibration base to calibrate the spectroclorimeter,
there is a blue cast on the white patch. If I don't compensate the
white point, white appears blue on soft proof (prints are good). If I
compensate the white point, soft proof is yellow.
- if I calibrate the spectrocolorimeter on the paper (without white
point compensation), everything is ok (except contrast) and the prints
are nearly perfect. I know it is not the good way, but the result is
better...

That "veil" is from your measured black. PrintFIX PRO 2 (which, by
the way, you should upgrade to Spyder3Print) always softproofs using
the measured black; which is never going to be a "perfect" RGB black.
This produces reduced contrast in the softproof; more so if you're
profiling a matte paper (higher "L" values for black, usually in the
18-24 range) rather than glossy or luster (much lower "L" values for
black, usually in the 3 to 5 range).

There's nothing you can do to change this in our software; Show Edits
won't affect this. But in Photoshop, you can softproof with black ink
simulation turned off (this is Photoshop's default). Go into View:
Proof Setup:Custom in Photoshop, select the printer profile and
rendering intent, and check the Preview box.

You should ALWAYS calibrate the spectro on the base; never on
anything else!

There's supposed to be a blue cast on the white patch (meaning:
the white of the paper that you're profiling/measuring); because that's
the color of the paper. Most papers measure with a slight blue cast.

When you softproof through the profile in PFP, the paper white is  
simulated
that way because... that's how the paper measured...:-) "By the  
numbers",
it's correct. We don't have a way in our software of turning off  
either the
black ink simulation or paper white simulation in our softproof; if  
you want
to softproof images that way, when you're printing real images after  
building
a profile, you should be softproofing in Photoshop, which is where  
you'll
actually be printing your images from. (So this comment goes along  
with the
first one, about leaving black ink simulation turned off while  
softproofing
in Photoshop; you'll probably find the closest perceptual match  
between your
calibrated display, and print, by softproofing in Photoshop with both
black ink and paper white simulation turned off)

That's right, its not the good way, and it will throw all of your  
measurements
off in subtle ways, so.... don't do it...!

*** Spyder3Print

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. It has download links for both  
the OSX and
Windows versions. I've attached a copy of the Update Notes to this  
ticket (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.

Thank you for your answers. I will try with white and black
compensation newt week-end (not at home this week). It is matte paper...

I don't have photoshop but Qimage. The chart is printed with Qimage
then measured with PrintFix Pro (I wil update, Ididn't know that I
could upgrade. Thanks colorvision!).
When I say that white becomes blue on soft proof, it is in Qimage.
Turning on black compensation in Qimage doesn't change anything. I've
never soft proofed in PFP.

What I don't understand with the blue cast:
- when I calibrate the spectrocolorimeter with the paper, all the
patch are as I see them on the paper. That is, I think, a ggod thing...
- when I calibrate it on the calibration base, all white colors are
blue. This is quite different from what I see on the paper! And I
should see on the screen what is on the paper during the measurement.

My english is poor and I'm sorry. What I understand from the last (and
long) answer is that PFP can't change anything to my uncontrasted
softproof in Qimage. What I can try is to turn off black ink
compensation in Qimage.

I did it because of the blue cast. Ref white did a yellow soft proof.

Not a good news... When the spectrocolorimeter is calbrated on the
hard white support (the good method), it gives 0.1 density and gray
color. Then, when I measure the white patch of the printed chart or a
new white paper (Hahnemuhle Natural Art Duo), the measured color is
bright cyan. The right patches of the extended gray chart are bright
cyan too.
Whites on soft proof are blue if ref white unchecked. Whole soft proof
is yellow if ref white is checked.
I cleaned it with cotton without alcohol. I'll try with alcohol next
week-end.

Thanks for all.

What is usual and what is wrong?
Paper is Hahnemuhle Natural Art Duo. Matte paper.
 - Grammage g/m2 256
 - Thickness mm 0,38
 - Whiteness % 88,5
 - Opacity % 98,5
 - Media Colour natural white not bleached
 - pH-Value total 8,1
 - Cobb g/m2 74,0
 - Ink limit % 250
 - Water resistance very high
 - Special features coated on both sides
Chart is printed in Qimage (ICM off...), soft proof is realised in
Qimage (I haven't tried in S3P), prints are printed in Qimage (profile
with black ink compensation).

Calibration of the spectrocolorimeter on the base (white disk) gives a
light gray, 0.1 density.
Measure on a not printed piece of paper (natural art duo) gives a
light cyan. Which could be explained, as you said, by the artificial
white of the paper.
The prints are quite good (better when calibrated on the paper instead
of the white disk of the base).
Does the spectrocolorimeter need a replacement???

The issue is soft proof. Automatic ref white (with calibration on the
base), soft proof is yellow and psychedelic :D
Reading help of spyder3print make me understand that I must use ref
white in order to reach a white similar to the paper white. It was not
clear in my mind.

I will try ref black for the lack of contrast. The idea is also to
reach the black of the paper?

Black ink compensation in my printing software doesn't do anything to
my eyes, at least in soft proof. I'm not sure about prints. IS there a
link between black ink compensation and ref black in spyder3print?

I know that I repeated a lot of things and that I feel like an idiot,
but advice are a little bit opposite.

Anyway, thank you for your answers. My understanding of the process is
better now :D

That's fine. What you're talking about is: calibrating the spectro
on the white tile; and then taking a measurement of it; which is  
technically
possible (by using the extra commands we provide in the Tools menu;
you can use the Calibrate command there, and then the Measure command,
to take a spot measurement of anything that you like, including the
calibration tile itself).

(In the normal course of running through the software's UI, you would
not take a measurement of the white calibration tile).

It should never measure as a "light cyan" - any measurement of paper
white that looks like cyan is wrong.

The "slight cast" being referred to for a paper with optical brighteners
is very slight, for instance: a "b" component of -3, or -4. This won't
look like cyan at all, the paper white measurement will be something
like Lab = (95, -1, -3), which will look like a very light gray with
an extremely slight bluish cast.

There's a world of difference with what I'm describing here and an
incorrectly measured paper white that turns into cyan. (The "b"
component in the "bad" case will be more like -127, not -3). The
patch measurement will look like a brightly colored cyan if its
wrong that way. It would poke you in the eye as being obviously
and totally wrong.

Psychedelic is wrong. If you're seeing banding or weird colors in the
soft proof, you have bad measurement(s), and white measuring incorrectly
as cyan (which should, remember, being poking you in the eye if you just
look at your measurements) would count towards that quite heavily.

Checking your measurements should be a simple thing; everyone who is
using PrintFIX PRO/Spyder3Print should be doing this, so in the interest
of all of our mental health, I'm going to post a separate message here
as followup telling everyone -exactly- how to do this...! :-)

Spyder3Studio already has a discount built in as a bundle (you get  
Spyder3Elite and
Spyder3Print, together, for less than the separate prices of both);  
there's no

If you'd like us to examine your files, please open a support ticket  
on the Colorvision
web site (put "attn: David Miller" in the title) and I'll look at them  
there.

If the problem is with the spectro, I believe (but David Tobie will  
correct me if I'm
wrong) that the warranty is for 2 years to the original owner, and if  
you fall into
that category, replacing the spectro would be free.


David Miller

that's all that I can do for the moment because I'm not at home until
friday. You can see what is the problem with cyan with the measures.
This must confirm your opinion about a device issue.

The measure of the paper after calibration on the base is Lab:
(99.31,-0.28,-100.26)

I will clean the spectro this WE but I cleaned it before the
calibration (without alcohol).


I tried the ref black (automatic) but contrast is still bad in soft
proof. It is perhaps linked to the spectro issue but the prints are good.

If your paper white measures with -that- Lab value, then it's
measuring (incorrectly) as CYAN, and the measured patch will look
a colored cyan, it won't look anything like white at all.

It should be perfectly obvious that what your measured value
isn't coming in as paper white.

Conclusion:

a) Your spectro is bad, and needs replacement.

b) You will never be able to build a good profile from the
measurements. (So I don't understand "the prints are good" part of this)



David Miller

I think that only white is bad during measurement. The efect is bad
soft proof as you said (I said psychedelic :D)
Is it technically possible?
I hope that cleaning it will resolve it. I need a good profile now
(100 A3 to print).

Prints are quite good when calibrated on the paper itself (I know it
is bad). A little bit of yellow, but very slight. Soft proof is not
contrasted but prints are have a good contrast. I can't explain it, it
is what I see.

If you open the measurement files I gave, you may see that only whites
are bad during measurement but I'm not a calibration professional and
I don't speak fluently Lab (neither english!).

My last tries after cleaning the tile and the spectro:

- calibration on the white tile
- mesaure of the white tile: L:90.47 - a:-1.07 - b:-1.30 - density:0.11
Is it normal?
- measure of white on the natural art duo paper (cyan):
L: 99.46 - a: 1.41 - b: -101.31 - density: 0.01
- measure on a classical white paper (word printing):
L: 99.70 - a: 2.66 - b: -109.49 - density: 0.05

I will ask for a RMA. Do you think that an adjustement is needed
(which I could do with a maintenance software) or that it is an
hardware failure?

Thank you for your help. I hope that it won't have to wait to much
time. I have about 160 A3 to print the next weeks...

I cleaned the spectro with another alcohol (swedish drink alcohol that
I 've never tasted :D)
And it works! Whites are white! I can't believe it!

Prints are very good. It lacks perhaps a little bit of red. 

Contrast with white ref and black ref is quite good but prints are
closer to original than to soft proof.

I won't change my profile for now and will print as it.

Thank you for your help.
