Loris,

If you read the Piezo plugin instructions carefully, you will notice that
one must "calibrate" your monitor by eye for printing with the plugin.  This
involves the grayscale settings in the color settings set up box in
photoshop. The instructions are a little confusing and it took me a while to
figure it out. I did learn that your grayscale file should have no workspace
/ greyspace tag so set your image to no color management.  If there is a
colorspace tag for the image, the monitor will always compensate, and you
will not be able to adjust the image to your piezo output.

If someone here can explain this more clearly, please step in...

in the files section there is a tutorial by Tyler about these settings, and
an update for those using the PT's.  Files - Image Processing - matching
your monitor view.

I have never experienced flatness with Piezo. My guess is that the file
itself needs adjustment.

Thanks for addressing Tyler tutorial, I will inspect it...

According to me the file itself doesn't need adjustments; I work on a
calibrated monitor and the print I made with Woolf workflow was very close
what I was seeing on the monitor...

Regards,
Loris.

that's not the point. Every workflow (technique, paper, ink, printer) has a
different input - output curve and therefore it should be calibrated
individually. With colors you can use the icc standard and the corresponding
measuring tools and software to control the hardware (if you are willing to
spend a few thousand bugs). With Piezo it is different and you have to
adjust the monitor visually to match the print and compensate for individual
hardware (the other way round and not totally equivalent). If you have
achieved a pretty good match you should adjust your image in the appropriate
way to get the "right" print. As a result your image data are changed and
somewhat different if you print with Woolfs workflow or with the Piezo
driver.

You could use Tylers method and Photoshops color management to recalculate
the image data if you have saved your dot gain curves as icc profiles for
each workflow. But I think this is not really recommended in the Piezo
manual for one reason or the other...

Peter

Thanks for the answer Peter..

I think rather different (just the opposite actually) on this; given that I
have a calibrated monitor which displays the image just as I want it to be,
then I would expect the Piezo plug-in to translate the data using its
proprietary (paper + ink specific) profiles and print it using its
propietary (printer specific) screening / weaving / whatsoever algorithms
giving me an exact / very close match to what I see on my monitor. This, is
a solution that I would call *plug and play*.

Anyway, any help that you provide is greatly appreciated...

Loris.
