QTR-Quadtone RIP

I have no problem with the design choices of LightRoom. I do have a problem with its lack of consistency in its handling of Jpeg metadata. A jpeg from the export modules contains ppi information understood by QTRGui, while a jpeg from its print module does not.

Part of the problem might be with QTRGui, because other programs get the proper ppi information from whatever jpeg LightRoom outputs.

I have more faith in QTRGui being corrected than LightRoom, though.

There is no point in outputting printing to other formats, as very few users want them.  The only example for other formats I can think of is TIFF for those using QTR.  After all it is a print module, so we only expect formats which can be directly printed, either on your own printer or through a photographic shop.

This is why we have the “File/Export” option, which is available for all modules of Lightroom.  This allows saving the file as JPEG, PSD, TIFF or DNG formats.
