I had to do some research but, yes, it's the same software. The
original Qimage was developed by DDI Software and was Windows only.
Apparently Binartem is a new company they're working with to make the
cross-platform version. I had no idea until now.

Mark, is this the software??




If so there's a Mac version.

Re: Printer reccomendations

[P. J. Alling]

I think they effectively do give them away.  Printer company's follow 
the Gillette company's or Kodak's old film marketing plan. Gillette gave 
away a moderately expensive razor and made their money selling the 
refill blades for more than they were worth, Kodak didn't care about 
making cameras really, they sold film which every camera needed, one of 
their engineers was once said to have remarked that the packaging of a 
35mm film cartridge cost more than the film inside.


Sadly in their death throws Kodak tried to sell printers for what they 
cost plus a reasonable profit margin and ink for what it cost to make 
plus a reasonable profit margin.   They apparently failed miserably at 
that, people were more willing to buy the almost free printer from the 
other manufactures and pay through the nose for inks.

Re: Another Printer Question

[Godfrey DiGiorgi]

The native resolution of most Epson printers since 2000 has been 1440 dpi (dots 
per inch). Dots per inch is not the same thing as pixels per inch (ppi) ... a 
dot is the size of of the minimum ink spot the printer can generate, but it 
take multiple spots of the discrete inks overlaid to achieve the range of 
colors that the printer can manage. 720 dpi, double that spot size, isn't 
really enough area to image a pixel that can be contributed to by four inks (C, 
Y, M + Black). As a result the 'native' or 'best' resolution of a 1440 dpi 
printer in pixels is really better considered as 360ppi.

Epson's driver algorithms make PPI resolutions that are integral multiples of 
60 in the range of that maximum resolution point print best (180, 240, 300, 
360). These numbers are specific to Epson printers and print drivers; other 
printers and print drivers may well differ as it is algorithm specific. 

Bruce Fraser covered this subject in his book on color printing many ages ago 
and in his workshops.

Re: Another Printer Question

[Igor PDML-StR]

I would guess that the odd number is to avoid it being a [higher] harmonic 
of something else (native resolution, spatial sampling frequency, ...)


I've heard this type of advice to avoid aliasing-related artifacts.
I have some intuitive feeling why that *might be* the case, but I don't 
understand it at any reasonable level (and definitely far from being 
able to explain it).

That's because 360 is exactly half of 720, the native mechanical
resolution of Epson printers (newer ones are double that at 1440) and
2:1 interpolation is simple.

I do my printing with Qimage software which uses its own resampling
algorithms to convert each image to the native resolution of your
printer at the print size you're making.

I can print to a file in MS Office (on the printer dialogue, eg select 'PDF') 
but no such option in the CS6 printer dialogue. Can only 'Save As' to output a

Re: Printer reccomendations

Related to that is a very old joke, but a good one:

A college physics professor was explaining a particularly complicated concept 
to his class when a pre-med student interrupted him.


"Why do we have to learn this stuff?" The young man blurted out.

"Physics saves lives," the professor responded before continuing the lecture.

A few minutes later the student interrupted again: "So how does physics 
save lives?"


The professor stared at the student for a moment. "Physics saves lives," he 
said, "because it keeps the idiots out of medical school."
