I use QImage all the time for my printing on my Epson 9880.  I do a lot of digital paintings using Corel Painter.  When I zoom in to actual pixels in Painter and Qimage the brush strokes are very visible, but after I print on to the Epson canvas the brush strokes are pretty much gone.  Is there some settings I need to change to prevent this from happening?  I tried sharpening in Qimage before printing, but not much improvement. 

I have Studio version 2009.268  Prints are 16 x 20 and up.

If anyone can help that would be great. Cry

Thanks!

Hi

Could you post a list or a screenshot of your printer settings? Also, could you send me a bit of one of your files so I can try it out? Crop an approximate 10x8 section with good brushstrokes without changing the resolution, save it as a maximum quality jpg and email it to brian{at}secalis.co.uk.

I would add 2 cents worth to things to try.
In the 9800 Driver, there's a setting that says, FINEST DETAIL.
 
This changes the input ppi from 360 to 720.
If you haven't tried that yet, might be worth a try.

Thanks guys for the prompt reply.  I am at work today, but will give both suggestions a try when I get home to my computer.

No work when you have Qimage and a 9800.

"Superfine 1440x 720 dpi", watercolor paper radiant white as designated by

That setting is probably ok, but there is one even finer.
You can see level 4 to 5 in the screen snap.
The one I was referring to is the input resolution. See the same screen snap with the check mark in FINEST DETAIL.
You will find that in Print Options.
The other screen snap shows Qimage reporting 720 x 720 as the input resolution.
When yours shows that, you have it set to maximum detail.
If you are looking for semi hidden brush strokes, you ought to try the finest detail the printer can offer.
Input 720 ppi and output and Level 5, Max quality.

Good luck

Hey Fred and Brian - Thanks so much for your suggestions.  I had emailed Brian the files he had suggested and I hope they made it to him.  I accidentally clicked on "remove" on my post from  last night, so not sure if you had both had a chance to read it. 

Basically, for the most part I believe my printer settings are ok - Fred, your screen shots look a little different than mine, but I will check it out when I get home.  I suppose the 9880 could be a little different from the 9800? I will also check out the Qimage resolutions as well. 

Do any of the filters applied in the "full edit" screen (I hope I am using the correct terms) make any difference as to the sharpness of the final print?  Or what about the settings in the "print/job properties" in the main preview screen.  I tried setting the interpolation to SE Hybrid, and also increased the other settting next to it (that I can not recall without looking at it)  Does any of this make any difference in the final print? 

Sorry to be so lame in my descriptions, but when I get home I will be more specific if you have not lost interest in this thread by then. 

Again, thanks so much to both of you for your helpful efforts. 

Rhonda

You are better off with Hybrid without the SE degree after it's name. The SE is a tad softer.
Recheck your driver under Print Quality, Quality Options.
You will fine a box for Finest Detail in that section.

ok - this is probably too much information, but I just discovered my snippet tool and have attached every thing that I could think would make a difference.

I hope I have done this right - may be too small to see?  Also, Printer Profiles rendering Intent is set on perceptual - I have selected the others and saw no improvement in the soft proofing, but have not tried to print.

Fred - I checked out those quality options you were talking about, but with the canvas settings it will only allow me to adjust down.  When I use the fine art papers it will allow me to increase to 5.   However, Canvas will let me select Finest Detail.  I have not tried either of these yet, but will on my next attempt.

Thanks for your patience with me on this. 

Brian, I will attempt to re send the email I thought I sent last night.

Thanks to both of you,
Rhonda

Thank you for the files , I will try printing them later today. What is the overall size of your file in pixels?

Please put the check into Finest detail. When you close the properties box the input ppi should change to 720 x 720.. If it did not, go back and recheck Finest Detail.
The driver for the 9800 allows highest output with your paper, but you said you have the 9880, so it might be different.
Nevertheless, when I use the highest DPI output on my printer, I need a magnifying glass to see the difference and I had better be looking at a tree trunk with a lot of detail.
So that is a minor concern.
I have one last comment, and then I leave you in Brian's capable hands.
Please, do not rely on softproofing to to try to get any idea of what the real print will look like.
Especially, in your case. You are looking for detail after printing on a very difficult paper to achieve detail.
You must test by printing.

Good Luck,
fred

Fred, Thanks for the reminder on the soft proofing - I do know not to rely on it (thank goodness, my prints come out better than the soft proofing) - but was just changing the rendering intent to see what changes were apparent in the soft proofing image - and there were, but only in the brightness of the image.

I will check the finest detail box and see if it changes the ppi - I'm sure it will, I just forgot to look last night when I was doing all that.  The snippets I posted were exactly as my settings were from the job recall for the print I was unhappy with - didn't want to confuse things by changing up.

Hey - thanks so much again for your help - you will probably see me again!

Hello Brian - glad you received my file.  Sorry to say I do not recall the exact pixel size of my file - I assume you mean the original file?  It was a Painter file and was 8 x 10 and 300 res. as suggested for working in that program.  My final print on the canvas was 16 x 20. 

BTW - probably makes not a difference, but I only use Epson media and Epson ink and use the canned profiles that came with it.

I will try to look tonight to get you the specifics.

Thanks!

OOPS! Sorry Brian - my image in Painter was 8 x 10 but for some reason it was 600 PPI (I usually make it 300 PPI to work on) and the total size says 110MB -I hope that is what you meant.

Good night all!
