I had a customer bring in a damaged sepia tone to copy/repair so i photographed it and then resepia toned the image in lr to get it same as the original.
when I printed it in Qimage however it came out as a b/w?
 So I tried to print in LR and CS5 and it came out fine just like the screen image.
Why did Qimage produce a b/w ? how is that possible?
every thing is calibrated and the Qimage out put normally for b/w and colour is spot on but not with this sepia .
any ideas any one.
images attached.

I am not sure if the image I downloaded was already in sepia or before sepia coloring.
In the Qimage editor I get readings in teh white cliffs of RGB 219,201, 198
Readings on the gray cliffs ,75, 68, 60
I made four prints,
One from Qimage, one from Irfanview, one from Photo Shop, and one from Corel Paint.
All alike... a gray with a slight lean to green.
If I add the sepia filter in Qimage and print; comes our Sepia.
Don't know how you got sepia from the image you posted.

Fred

I get similar results to Fred.
Sky 115,110,98
White cliff 205,198,192
Cliff top on LHS 26,19,13
All the readings seem to show a small bias towards red - is that sepia?
I too did a small print on Ilford smooth pearl with a proven custom profile and a print the matched the calibrated monitor perfectly when examined under an Ott light.
Like the RGB readings & screen, the print seemed just a little warm but not a definite sepia tone.
There are some things we need to ask, which may seem rather obvious to a pro!
Are you using layers in the image to give the sepia effect which are not read by Qimage or show up on your attachment. They need to be flattened.
Are you using a fully colour managed process with monitor profiled and a good printer profile.
Have you checked your driver settings from within Qimage? Make sure they are set for ICM no colour adjustment etc. and that grey scale printing has not been accidently ticked.
That's all I can think of for now but what you show on your attachment is a slightly warm B&W image, not a definite sepia as I would understand it.

PS. I read your image as being Adobe RGB colour space.

I selected 2 images to attach to the post and seem to have lost one. I will resend tomorrow as I am not at work now.
when I photographed the original on my copy table the image was much more b/w than the original and I used a sepia filter in Lr to correct the image to match the original. It might not be true sepia but that's what LR called it.
yes image flattened
yes all calibrated , as stated I never normally have a problem with colour in Qimage work flow, therefore driver settings are correct,and grayscale printing is not selected.
I will repost the two tomorrow with notes to apply to each one.
It's not a issue as such as I have printed out what i need, it just  a curiosity as to why.
thank you for the interest and time taken

The one image was 187KB and the total limit for attachments per post is 256KB that is why one disappeared.
We await the other one with interest  ;)

What I see on screen in your post is about what prints out, that JPG,
Using 4 printing programs. I don't have Light-room, but I managed to print from Photo Shop; all the same.

Just for fun, I added a sepia filter to your JPG.
I made two.
One is the sepia filter, and the second I toned down a little with a minus 20 saturation, plus I added a noise filter which didn't hurt.

Fred

here is the original that I had to work with, I cant save any smaller than this with PS so only one image. the original was very grainy which i initially removed but then put back as the task was to try to duplicate the damaged print.
there are some undamaged ares which was what my "sepia" tone is  replicating.
Once I repaired the damage I converted to b/w to remove all the colour casts and then added the sepia gradually to get as close as possible to the faded original which is what the client wants.
what I don't under stand was what setting I have applied or unwittingly set in Qimage that make it ignore the sepia or more probably is converting it back to b/w. It has to be me of that I'm sure as  the program produced two perfect colour prints also water damaged and repaired from the same client.  

I will tell you one thing I see!
You did a magnificent job of repair and restoration.

What I would like to have, and so would Terry, is a copy of the actual image that you use to make the print. The earlier image wasn't in sepia.
Then we can see what Qimage saw when attempting to make the print.
Fred

Hi,
I've downloaded the original image (what a mess!) and got the following RGB reading for similar areas as the repaired image.
Sky 115, 106 87
Cliff face 201, 191, 173
Cliff top on RHS 26, 21 17
These reading are slightly biased to having less blue than your repaired image, ie. more yellow.
I'm sure if I printed it I would get a good match.
There is only one way for this to happen in QU, that is a filter has been applied with the Image Editor. The file name under the thumb will turn red to show that. There could be a print filter set and that would show as a tick in the P.Filter box, bottom right of the main screen.
Have you got some weird profile set in Qimage?
Terry

........ just to add to Terry'a thought, Photo Shop makes an .XMP file to carry it's layers and adjustments.
Are you sure that you created your Tif file that you are using in Qimage which includes those enhancements?

Also would like to know if you can email the Tif, or is too big, can you convert it to a JPG for emailing?

Fred

what do you use to resize? ps save as smallest is ok size wise but wrecks the iq

sepia [sort of ] version tinted in lr and saved to a folder as as jpeg.

ignore the image atteched here it is a early attempt I saved my mistake.

Sorry,
But I am getting somewhat confused.
So far, I haven't seen anything resembling a sepia tone.
Therefore, I am not sure what you have been posting.

If what you posted is what you are using as the source image to print in Qimage, you won't get a sepia print from these images.
How about this question.
Is there any chance that you are printing from a .PSD file from Photo Shop which has the sepia layer, but have made a different image to be used to print from Qimage?

Thanks for the offer I have found for some reason that if I use the sepia tone preset in LR develop mode and save it then it gets lost or is not shown unless Lr or PS prints it, however for some reason if i add  a sepia tone in PS and reduce the opacity till it matches the print, flatten the 2 layers it and try Qimage then Qimage faithfully prints it. either something odd with my set up or a Lr anomaly anyway I know next time if I want to print sepia tone how to do it.

Don't know too much about LR, but there are plenty of expert users on here. Maybe they can comment.
Nevertheless, happy that you are sorted.
I have access to CS5 for a while as I am poking around in a friend's computer.
I can make  layers with any filter and multiple filters, save it, and Qimage will print from the PSD file using the adjustments.

That's all I can offer.

Beautiful restoration job. I am Wow'ed

Fred

Thank you , you are too kind.
The customer is very happy as well. with a new frame that we made for him the whole job came out very nicely, lesson to be learned don't leave your art work in a damp garage when you move to a new house!!

Hi
I've just tried using the Sepia preset on a file in Lightroom, exported it and printed in QI and it came out with the correct sepia colour that I see on the screen.
Sorry if I'm being a bit negative  :(, sometimes things happen which you can't pin down.

Brian

Hi Brian,
I'm not familiar with Lightroom but I would assume that any image adjustments made are "non-destructive" (like a QU filter). Is that correct and does the export process make a new image with he adjustments included?
Obviously LR can read these and include in the printed image, and probably CS5 too, but not QU as you would expect.
Maybe this is the cause of the problem - the image has not been exported or new image created with the sepia tone included.
Terry

Terry

Lightroom exports the file with all the adjustments made, although as you say the original file is not changed. The changes are stored in the Lightroom catalog or as a separate sidecar (.xmp) file or both, but  it can only be read by Lightroom or Photoshop in the same way as the QI filter file can only be read by QI.

Brian

Hi Brian,
I suspect our original poster did not "export" the file; that's the only thing that I can see caused the problem.
You have shown it works fine for printing in Qimage when you do that.
I hope adwd reports back to put this to bed.
