Trying to print a poster of a collage of kid's golf photos for a banquet and can't get a quality print. Using a FOJr and printing on Oracal 3951, using 3951 profile, rendering intent to perceptual, heaters at 50 and 40. 720 print res too grainy. Read on forum to try exporting to tiff and got good quality at 1440x1440 but now I get a "four band strip" of lighter print about every 1/4" inch. Not quite as noticable in the sold color border but very noticeable on subjects' faces. Other than this band or strip, and the photos printing a little darker than the originals, the remaining print is pretty good. Used Flexi to make poster and rip/print. Two questions: ideas what's causing/how to remedy the lighter bands, and second, what's the best way to lighten the print? Any input would be greatly appreciated!
