Crumbs of missing information

After reading the user manual and watching the accompanying videos, I’m not sure about some things. I would be happy if someone could confirm it.
With simple YES/NO answers.

  1. It is better to print from OSX (Yosemite) than Windows, because the Print-Tool utility only runs under OSX. Does QTRGui not have that many options?

2, For PiezoGraphy printing, only the “CURVE” file contains the fitting data, never use an ICC file in the Print-Tool program?

3, PiezoGraphy only uses ICC file to support soft-proofing. For example in Photoshop?

4, Print-Tool program supports QTR black and white printing with OEM color ink set. In this case, you should use QTR matte or QTR gloss ICC files and enable Color Management in the Print-Tool program. As it is in this video at 3:00.

In this case, the ICC and CURVE files mixed with sliders determine the final result together?

5, QTR printing with OEM color ink set minimizes the use of color components. Even under a microscope, you can’t see colored pigment dots like EPSON ABW?

  1. In the long term, pure Piezography CARBON ink ensures the most durable (light fastness) print. It lasts longer than any other shade, e.g. the variable tone Piezography PRO?

7, Pure carbon K7 inksets offer more gray scale (number of shades) than other mixed cool/warm inkset like PRO. After all, there the individual curves are limited due to the production of a warm or cold tone?

QTRgui is far inferior to PrintTool yes.

The curve is like a media type selection. It is linear by default. It does not do a contrast match between the monitor (1:200) and paper (1:150 or so) so there is some work to do if not printing with an ICC in order to do that transform.

You can use an ICC that’s fine. I’ve found that black point compensation is slightly inferior than doing a linear soft proof (and subsequent contrast adjustment) in Photoshop and then just printing with no color management (aka NO ICC) out of PrintTool though.

Sure in that case the ICC is just adding the required S-curve to the file at print-time to match your higher contrast monitor. You can print with those QTR Gloss/Matte profiles for piezo too or you can use the Piezography Matte Print or Piezography Gloss Print profiles too . . .

not exactly true no. You can still see dots with QTR.

True, but it’s all hundreds of years with either set.

Not really true actually.
