OK, i just did a side-by-side. same image printed using quadtone rip

Really?

Fantastic.

Can you give us more details?

Re: [Digital BW] RE: Quadtone Rip

2004-09-10 by johnmuir.geo

More details:

to sum up, smoother transition, especially in shadows and dark areas. 
The IP image actually is a bit posterized in these areas, while the 
quadtone is smooth.

I'll do more testing as I get to know the program better. Anyone know 
how I get it to print on 13 x 19 paper, instead of letter size. Also, 
how do I plug in different curves?

thanks

Posterized shadows is not a characteristic of IP, at least on my 9600.  There must be some other issue.
 
(I'm not throwing stones at QTR.  From what I've seen the quality should be a match for IP.)

Wow! At 12:10 PM you posted to ask about QTRIP--and sounding (to me)
as if you had "heard a lot" but not ever used it. Then by 2:10 PM you
have got it, installed it, run a test print and made a side-by-side
comparison with IP output. That must set some kind of record. Amazing!

BTW, I'm curious why--if you already owned the co$tly ImagePrint--you

Hi Phil

Just curiosity, I guess. I'm after the holy grail of inkjet output 
that is indistinguishable from silver, so I'm willing to try stuff. 
Got a good recommendation on QTR from someone here at the College of 
Santa Fe, so I was primed.

Anyway, I've scanned the two prints, and will try to get 'em up on my 
website over the next couple of days.

[Digital BW] Re: Quadtone Rip

2004-09-11 by johnmuir.geo

I think the difference is most marked in the differences in tonal 
transition in the background..actually the "desert varnish" on the 
rock. The IP image seems to me to have more trouble dealing with that 
transition. But the biggest difference is that the QTR print looks 
more like what I have on my screen.

These are first impressions only. Eventually I plan to try this 
comparison with other B/W images.

Frankly, I would be happier to find that IP is, overall, superior. Or 
at least better for certain images...just another arrow in the 
quiver. After all, that thing cost me plenty.

I am no expert, but that is the look that my prints get when they are

up" I mean that i have to figure out why the paper/ink combination is 
not working. That print just has problems. The blacks are all blocked 
up, and the it's also too light. It's not dialed in. By trial and error

Not much "dialing in" available on the IP version (lite) for the 
2200. sliders are disabled, so there really isn't much room for 
error. And, don't get me wrong about IP, even for color, it's still a 
bit better than any profile I've used.

As far as I know you have to add the profiles as a variable. Those that were
supplied with both RIPS will effect the image differently. You can tweak
your QTR file so that it prints more similarly to the image print output
which appears to have more compression in the blacks .. Whereas the QTR
image appears to have a smoother range throughout.

I find that if I'm using a file previously printed through another driver or
RIP I have to add an S curve or at the very least drop the lower blacks so
that it prints similar to the previous output. This again I feel is because
the profiles supplied with QTR handle the files well, without the
compression inherent in other methods I was using.

If I am printing a new file, I manipulate it for the QTR output, using the
softproofs supplied by Carl, and the match is very nice to the screen.

Bottom line in my opinion is that each RIP / profile combo will handle your
file differently, reliant on the way the RIP handles the data yes, but also
reliant on profile, and linearization... and you have to manipulate your
tones in the image file to reflect the desired output from each.

So to do a straight comparison with these variables in mind, is not doing
either RIP a service. I'd appreciate being corrected if my thoughts are off
base.

IP vs QTR vs any RIP [was Re: Quadtone Rip]

2004-09-11 by Antonis

Jack,

I don't know how long you've  played around with these printing
methods, but the right profile is really  key to succesful bw printing.
The big advantage of QTR, IJC/OPM and StudioPrint is that 
they all offer ways for the end user to make or tweak a profile 
to suit their personal preference or equipment.
With IP and others, you have to depend on the company to calibrate
the system for you. In fact, with that in mind, IP offers to make you a custom
profile if you send them  a printed target (for inksets they support).
 That takes the work out of your hands but in turn means 
that you can't tweak things on the fly.

In order to compare RIPs then, you have to make sure that each is
running profiles calibrated and linearized to your particular system.
It's for you to choose if you like to do the profiling or have someone else
at a distant location handle it. Depending on that choice, you go with the
appropriate RIP.  All these RIPs can be made to print nearly 
identical prints. Their differences are far more subtle than your
print comparisons suggest.

My recommendation is to go with printing software that not only
allows you to make your own profiles, but makes the process fast
and fool-proof. Beyond that, you'll need a good understanding
of color management in general, just to make things match across the
whole workflow.

Antonis

IP vs QTR vs any RIP [was Re: Quadtone Rip]

2004-09-11 by johnmuir.geo

--This is good, considered reply.  thanks, Antonis.

I am working with the supplied profiles by both developers for the 
inkset and media. I really had not expected that much from QTR, and 
was surprised at the result, so decided to post my findings in this 
forum. 

Indeed, I could work with IP on the profile issue; they've really 
been quite supportive. But they have a very up-to-date profile for 
the media I used for the test, and I doubt that they wouold see fit 
to tweak it further.  I was just interested in the side-by-side 
comparison of the "out of the can" profiles that each of the 
developers supplied. 

I realize also that I have much to learn in all this.

It's a little difficult to imagine shadow being produced by either RIP.  But, without seeing the original file in PS, it's hard to really judge.

John,

Why so limited in your horizons? Surely the 'holy grail' should be for 
inkjet prints that are better than silver? There is nothing magic about 
silver prints; they were just the best technique of their time for making 
photographs - which was rather a long time ago.

I've done comparisons between QTR and IP 5.6 myself and can say as far as quality, they are very comparable.  IP does give me finer control over the shadow with the black point slider.  

Make sure your Color Management settings in IP are correct.  Using the wrong rendering intent in IP, for example, can cause blocked up shadows.  Also, make sure you have the correct ink settings in the print dialog.

In my testing, I've noticed two visible differences between IP and QTR on EEM paper.

1.  IP produces darker blacks (higher dmax).
2.  IP prints look more neutral than QTR (which looks slightly warm using CoolSe/warm at 50%).

For the money, QTR is a phenomenal deal though.

1. Suggests you do not have QTR properly calibrated - try making your own
curves.

2. 50/50 is not intended to be neutral.  You need to decide on a mix that
you believe is neutral.  Again, you can make your own curves to produce any
tone you like.

Agreed.  I haven't spent any time making custom curves for QTR.  I've only used the provided ones so far.

Once I have more free time, perhaps I will play with that.

QTR Softproofing and Profile Tweaking [was Re: Quadtone Rip]

Hello Everyone

I just started experimenting with QTR(for Windows)on an Epson 7600 
printer(with Ultrachrome inks - with Matte black) and EEM (Epson 
Enhanced Matte)and HPR (Hanamuhle Photo Rag)papers.

Some of the posters on this thread have made reference to QTR having 
capabilities for:

- Softproofing

- Profile Tweaking

Could you please explain how you go about using these two features ?

Thanks

A heck of a lot easier is to just use the slider in QTRgui
(http://www.sbillard.org/Shareware/QTRgui.htm).

  1. Suggests you do not have QTR properly calibrated - try making your own
  curves.

  2. 50/50 is not intended to be neutral.  You need to decide on a mix that
  you believe is neutral.  Again, you can make your own curves to produce any
  tone you like.
