Just ran across something weird. I finally sat down to print all the stuff that has been piling up in my To Print folder. I print from a windows 11 box running Epson Print Layout. Normally, I export an uncompressed 16 bit tiff from darktable (debian) onto a shared drive. Open it in EPL and away I go. Today, EPL could not load the images. Old tiffs made in darktable 4.6, 4.8, and 5.0 (i think…) had no problems. They worked the way things always did.
I changed to using compression, changed to 8 bit, changed color space profile. No luck.
Interestingly, jpg exports open just fine. Also, if I load darktable’s tiff into GIMP and immediately export it again with the same settings, everything works fine. I can do the same in XnView. So, it seems, like maybe darktable is doing something a little differently?
Are there any recommendations as to where I could start figuring this out? I dont want to open a bug report on github without having more to offer.
I have seen similar issues with software and tiff files. Not a unique problem to DT. My solution was simply to open the tiff file in GIMP and export as a new tiff file from GIMP. Not the solution you are looking for but a work around. Hopefully DT team can work out what the issue is.
I can also confirm that tiff exports from DT will not open in the Canon Printing software.
PNG sounds a reasonable solution, but does anyone understand why Epson and Canon printers don’t like DT’s Tiff but like GIMP’s tiff. I suspect it has something to do with layers?
