Mike, Thanks for the explanation. Something I never noticed before.  I'll just have to keep an eye out for the file sizes on my drive.

I have to guess what you're talking about.  Since you said "opening to Qimage..." maybe you mean you open them in Lightroom and then send them to Qimage with the plugin?  That's the only way a .tif file will be created: Lightroom creates it when you export because it is the only way Lightroom can export images.

Opening Nikon .NEF images to Qimage Ultimate creates a .tif file. is this supposed to create a .tif file? I don't remember this happening. Do I have an incorrect setting in Qimage Ultimate?

OK.  Fixed in 2026.103.

Mike

I really only need to know the image profile was Prophoto.  I do see something that might need a slight tweak to force LCMS to do higher precision color conversions (full precision vs high precision).  White seems to end up at 254,255,254 in some cases when using the faster "high precision" method.  That might be what is causing a tiny color cast in white.  Surprised you can even see a 1 RGB change near white but I suppose depending on the printer profile it could cause the printer to put a tiny amount of ink on the paper.  I'll release a 2026.103 and we'll see if that fixes it.

after a few tests, some additional info:
changing printer output profile has no effect, issue remains
changing image colour profile has no effect, issue remains
printing to file, output to sRGB: issue remains
turning sharpening on and off has no effect, issue remains
changing interpolation method has no effect, issue remains

I can't share the image(s) I'm printing. Just test with any image with a white background. Most of my print output files are in ProPhotoRGB

Epson P9000 and P9500 - the issue presents on both machines
I'm using a range of papers, with custom profiles that have given me no issues for years.

The issue is not present in 2025.105 and earlier, but shows up in 2026 versions without any changes to settings, media and profiles. I can print from 2025.105 without problems, then save the job. Then I install any 2026 version and recall the job. I print and the issue shows up in the print preview.

Could you put the image on google drive and post a link?  I'd also need to know what printer, media type, and printer profile you are using in Qimage.  This looks like a profile issue but I'd have to have those things to check it out.

Regards,
Mike
