Epson Printers

I edit photos in PhotoLab 6 and want to print to my SC P800 via Qimage One (Mac). How should I export finished files from PhotoLab to Qimage?

Right now I’m sending 720dpi JPGs. Should I be using 16-bit TIFs? Or just 360dpi files and let Qimage upsize as needed?

Qimage is easy to use.  It should work well with tiff or jpeg.

I suggest you export out to a full-size file at 360ppi and use a 16bit Tiff file.   This will give you a file with the most info to make a good print.  Hope that helps.

You should be editing in “16” bit, but it is kind of pointless to print from it; it makes no difference. Many drivers accept high bit but only send 8-bits to the printer. Sure, if the driver accepts it, even if it sends all those bits (a few Epson’s on Mac do), there is no colorimetric difference I can measure, but you can send your master 16 bits to the driver. IOW, unless (like some native Epson drivers on some macOSs, it hits a nasty bug) you can leave the high-bit data as is. But you can send 8-bits too.
JPEGs, not ideal; lots of data loss from the original data. Send TIFF.
