can anyone tell me why L/R sides of prints are not in sync?
the left side of all my prints are 2 shades lighter than the right side of my prints! Any idea what might be causing this?
Been running my Mimaki JV3-160SP 60" printer for 2 years now and can hardly complain, I love it… until I noticed something while tiling this 90"x200" wall mural… at first I thought the problem was because the ink was running low, so I reprinted with full cartridges and got the same effect…
I printed all of the tiles at the same time, under the same conditions, off the same roll of 3M controltac vinyl, but the difference in color is dramatically noticeable once I tiled it up on the wall. A watermark image of a building goes from dark grey to light grey right at every one of my seams, fading back to dark grey just to snap back to light grey at the next seam. Luckily this wall mural is for my office, otherwise I would have a very angry customer and an unpaid bill on my hands.

possible head mis-alignment, run some test patterns and see if all your nozzles are firing as well.

this is down to head or machine bed height settings that differ at opposite ends of the machine.
it is usually only noticed when you do a tiled job as the lhs has to match up to a print on the other prints rhs.
to combat this some rips have a rotate alternate panels function so panel 1 for example gets printed at 0 degrees, 2 gets rotated 180, 3 is back at 0 and again 4 is at 180. if yours doesn’t then do it manually for each tile.
when the rotated panels are re-rotated after print the corresponding sides from the non rotated prints have been printed at the same side of the machine therefore giving the affect of a much smoother transition.
hope this makes sense and is useful.

yeah, I noticed that my talon rip server settings has a "Flip every other tile" option that I will definately use in the future just to be safe. I’m still going to look into correcting the lhs/rhs print height idea which sounds like the most reasonable explanation for this error. Yay for a day on the phone with mimaki service techs 🙄
