More on settings (in Qimage, and in the printer), than editing.

Since my specific use case is printing photos for other serious amateur photographers, I wouldn't edit their photos normally.
But I am responsible for getting the best printed results possible!

I don't do a lot of B&W prints but I know there are members here who do.  What sort of ideas are you looking for?  More on the editing side or printer settings to print the best B&W?  Maybe others can chime in.

I print about 20 contest-winning photographs a month for the photographers who took the photos, to display at 2'x3' in an outdoor public non-profit gallery (at a local church).  Most of the photographers have never seen their works this large. 
I do *everything* through Qimage.      The photographers love the results!

About 40% of the photographs are monochrome or black and white.   I am wondering if there are some Qimage settings that I should look into in order to do a better job with these photos.   

(I print on an Epson SC-P7570 24" printer, onto Canon Polypropylene Matt paper that has been custom-profiled for my printer.   I use this paper because it is the best I have found for quality photographs that are hanging outdoors unprotected from the weather.)

Thanks.  That helps: now I can see what you are doing.

Look at the top of the multi-panel UI: your print size is set to 19.76 x 26.35.  So when you enter 3x1, it is splitting up 19.76 x 26.35 into 3x1 panels.  It did that correctly because you can see all three panels side by side on the live view when you are done.

So you're skipping the step in my instructions where you specify 24x54 as the print size.  It needs that final print size so when you enter 3x1 it knows how big to make the panels.

Ok I have recorded the screen steps and as a recap I have a photo but need to get 3 18x24 prints out of it. I have a P2100 so 20" is what I set up for on the roll. I know I am doing something wrong so here is the link for my steps.

Thanks Mike

Yeah, it's a simple, pragmatic and efficient approach.
In fact, that's what's missing in PS and LR soft-proofing: we know it's out of gamut, but we don't know by how much.

Thank you for your soft !

Suddenly I can't seem to find Epson 157 ink cartridges for my R3000 printer.  Even the Epson web site offers a button to click to be notified when they are available. Has anyone heard anything about a general supply chain problem, or is this just a case of an older printer not having enough demand to keep a steady supply coming?

Well the algorithm is proprietary of course but to put it simply, it looks at the image and examines how much of the image is out of gamut on your printer and whether or not those parts are in important areas of the image.  If enough of the image is out of gamut, it switches to perceptual.  Otherwise it uses relative colorimetric.

Hi Mike.

I know about rendering intent, (at least I hope  .
But I'm  very curious to know how your auto option works to choose between perceptual and relative ?

Thank you for your reply

If it doesn't work, you didn't follow the steps or your page size is less than 18x24.  I'm not going to continue trying to guess what you are doing with no information about your specific setup so if you want further assistance you are going to have to create a video or screencast showing your steps.
