Hahnemule PhotoRag profiles

2006-01-30 by tflyfish2002

I am wondering if there are any PhotoRag profiles available for the
2200 UC inks? 
I also notice that most of the included profiles are either warm or
cool  but no neutral profiles, am I missing something?

I can't find the message right now, but within the last few (6 maybe)  
weeks someone here posted a link to profiles they had made.

Bazzer, the neutral profile can be derived by combining the warm and cool profiles.  That's 
why there is room for two profiles, with percentage values for each, in the QTR driver.

I tried that with the EEM and ended up with a very dark print. I will
give it another go though.
Thanks,

Thanks for the link. Unfortunately the profiles appear to be in .sit

Trial version of Windoze decoder here:

The demo includes the free "expander"
which is what you need, I think.

I'm PC too - I managed to find appropriate files somewhere there and downloaded them without problems. I'm on a 2100, however, and the print that resulted was too dark.

I posted that link the last time the question was asked here

I'm on Win - but I have downloaded and used those profiles and they work
just fine for Photo Rag.

And yes, you are missing something. in QTR you vary the balance between the
cool and warm profiles to get a neutral you are happy with (or a cooler or
warmer tone - anywhere along the scale)

Thanks for the info. I am downloading a suitable unpack program.  

I tried with a 50/50 cool/warm profile using EEm, but the result is
very dark print.  I have Imageprint 5.6 and that works very well on
the same image. I have used the default Ink limit and Gamma, surely
these setting should give me a fairly good result without having to
calibrate etc. Or should I?

Hi again Bazzer..... what setting for print resolution are you using in the driver?  Most of 
the available profiles were created for 1440dpi (or 1440 super).  If you are using 2880, try 
switching to 1440 and make a small test print.

Ed,
That seemes to have resolved the problem. I did also turn the Ink
Limit down to -8, now I'll have to wait for a while to let the print
dry to compare with the test image.
Very many thanks to you.

Re: Hahnemule PhotoRag profiles

2006-01-31 by edrudolpho

About the neutrality.... from what I've read, I think neutral would be more like 35-45% 
warm and 65-55% cool.  Of course it varies, but try something like 40% warm and 60% 
cool.

Re: Hahnemule PhotoRag profiles

2006-01-31 by None

I posted a question on this 2 days ago. this is the recommended method
but when I do this I get prints with tones bunched up. That is the
gray ramp is not smooth even though the gray ramp for both warm and
cool curves is very smooth and linear. 

Does anyone else see this? How do you linearized blended curves?

Convert to Grayscale vs Channel Mixer

2006-02-05 by Doug Walker

Can someone confirm whether one must 'convert to Grayscale' before  
using QuadToneRIP or can one print an RGB image out of PSCS2 after  
adjusting the image using Channel Mixer?

Re: [QuadtoneRIP] Convert to Grayscale vs Channel Mixer

2006-02-05 by Doug Walker

Thanks Alan.

I guess my pondering came upon seeing in Uwe Steinmueller review of  
Roy Harrington's QuadTone RIP where the steps which included a  
Greyscale image in Print with Preview with a source Grayscale 2.2,  
not an RGB.

So it does not matter?  RGB or Grayscale?  Is one better than tother?

Re: [QuadtoneRIP] Convert to Grayscale vs Channel Mixer

2006-02-06 by Roy Harrington

You can print an RGB file directly.   It gives a default conversion to 
grayscale.
So I would use the Channel Mixer to get a better conversion but you may
leave the monochrome image in RGB for printing.

Doug, I'm no expert but I think it does matter and that there is more  
image information left in an RGB image than a Gray Scale. That's how  
it was explained to me in a community college Photoshop class and  
that how I've been doing it, with great results.

My understanding as well.  Just confirming as I have no experience  
with QTR and saw Greyscale in a tutorial.  Had to ask.

Re: Convert to Grayscale vs Channel Mixer

2006-02-06 by Roy Harrington

If you shoot the picture in color there's certainly some benefit in retaining that
color info in Photoshop.   But the actual input to QTR is always grayscale.  If you send
a color image a conversion to grayscale is done automatically using a simple default
conversion.  I think in general you'd benefit by controlling that color-to-gray
conversion using Channel Mixer or other techniques.  If you do that, you get an RGB
file that is gray i.e. R=G=B.  This contains no more information than a grayscale image.
It will be identical data but three times the size.  The print result will be identical.
Whether or not you explicitly convert or not is just a matter of convenience.

Re: [QuadtoneRIP] Re: Convert to Grayscale vs Channel Mixer

Roy, I was printing with an earlier version of QTR last Spring when I bought it and then did not do much b/w printing for awhile. I also unsubbed to this mail list so think I missed some things.
As I recalled, the workflow for best prints was to process 'however' (I use a variety of ways), but to convert to a grayscale profile before printing. Has that all gone by the boards with the new version? Or--do I not remember the workflow correctly? (always possible LOL). I have 3 QTR profiles--lab, matte and photo paper. Are these obsolete--or do I need to review the conversion/printing process?
Thanks,
Diane

If you shoot the picture in color there's certainly some benefit in retaining that
color info in Photoshop. But the actual input to QTR is always grayscale. If you send
a color image a conversion to grayscale is done automatically using a simple default
conversion. I think in general you'd benefit by controlling that color-to-gray
conversion using Channel Mixer or other techniques. If you do that, you get an RGB
file that is gray i.e. R=G=B. This contains no more information than a grayscale image.
It will be identical data but three times the size. The print result will be identical.
Whether or not you explicitly convert or not is just a matter of convenience.

Hi Diane,

You remember correctly.  Converting to the Gray Matte Paper or Gray 
Photo Paper is still
probably the usual workflow.  What has been added since that time is 
the capability to
make custom ICC printing profiles in addition to the generic ones 
above.  There will take into
account all the nuances of your particular printer/ink/paper.  They 
also provide full soft-proofing
including the hue of the print.  Naturally you would need to have a 
measuring device to take
advantage of this new tool.
