Now that would be nice!

Did you watch this video. . . .

Which inkset were you thinking about?

Terry,

I have seen the videos, they still show normal Canon ink sets but I guess that could be altered.  In a combination with some QTR tools it should be possible to get partitioning etc right.

Extensions of the HP Vivera PK and plain MK, I have been thinking about that much longer and Paul Roark got the same idea some time ago but for use on Epsons. Since then he showed some surprising developments based on that Vivera ink.

There is a PC version of TBW planned I see. What also would be an interesting step is adding the Canon iPF510 etc printers to the supported printers. There is B&W potential in what is considered a CAD printer line.

QTR on the PC worked nice in the past for me but I much rather have it backed as a Windows printer driver and use it then in tandem with Qimage. No hot map in between does give you that workflow. TBW could be like that, I do not think I would mind that 16 bit has to be sacrificed for that.


met vriendelijke groeten, Ernst

TBW supports a 16 bit workflow, and it's a stand-alone application (just to clarify those two things). 16 bit support and a feature called "Grey ink reduction" (automatic calculation of ink buildup in the shadows to improve the blending of grey inks into black) were added with version 2. You have to go to the order page for some of that information (http://bowhaus.com/trueblackandwhite/truebw.php4).

I just spoke with BowHaus and the PC version is only in the planning stages. A few calls asking for the product might help move it along.

Adapting QTR approaches to aid with curve creation sounds like a good strategy. Their suggestion is to work off of an existing curve where they've already done the bulk of the experimentation. The other approach they suggest is to build a curve for each ink individually, which is documented within the download, then bring it all together.

I'm looking at the HP Vivera inks as well, Ernst. They should print neutral on gloss media, whereas my Cone Selenium comes out warm. In combination with MIS LK and LLK (a la Paul Roark's suggest) I'm hoping to create a nice sepia shadows to neutral highlights split-tone with this set. I'd also like to be able to do the same with TBW and my 8300, to support larger prints than I can make on my dedicated BW printer.

Terry.
