@Nyrryl-Cadiz @xin-li transferring is the part I hate most and something always seems to be lost in the transfer. I have a very old epson 2200 that uses pigmented inks, with a manual feed in back and a paper feed setting that is lever-operated to allow even 300# cold press paper.
I set the image transparency within indesign (quark also has that setting) to as low as it will go and still be visible because I don't use line work with my watercolors (anywhere from 20%-50%, depending on the drawing). I test this with thumbnail prints to save ink & paper and use the thumbnails for color studies.
Even though I have some HP inkjet printers that will feed 90# paper without any special settings, I don't use them for watercolors because the ink bleeds when water is applied. Some artists get around this by doing their sketch in colored pencil using the predominant color in the piece, but that would not work for me. Pigmented inks work best for me.
I think Canon has some pigmented ink printers that accept watercolor paper too.
