  1. new head, black ink starvation

    I posted in another thread about two new print heads. I haven't actually installed those yet, because I'm seeing some ink starvation in one the other two printheads, which were already professionally replaced by a skilled mimaki tech. We the black and magenta heads replaced, but the black...
  2. new JV3-160sp printheads - are these bad?

    We bought a couple of new printheads online. Attached are the photos. There appear to be some shiny dots, and some droplets. Should I send these back? Also attached are some PDFs showing how to replace the print heads, from those who've done this, any comments, suggestions, clarifications or...
  3. jv3-160sp: Rasterlink Pro II to III upgrade? Profiles?

    Folks, We have a mimaki jv3-160sp. We had rasterlink pro III, but our rip station's hard drive died. We have rasterlink pro II with the original install media and the dongle. When we reinstalled, we found we didn't have the upgrade from II to III. Mimaki no longer offers the upgrade...
  4. Black Cut Vinyl for Brick Wall Wrap?

    Line art seems to be the popular thing these days. Is there black or other colored vinyl for cut vinyl signs that is also suitable for a rough brick wall? I.e. like mactac rough rap, or 3m envision wrap, or alumigraphics, something that will conform to a rough surface, but just plain colored...
  5. laminating wall wraps

    I was talking to a vendor last week about their wall wrap product for rough surfaces (sort of like MacTac Rough Rap). He said they recommend installing the unlaminated wall wrap first, then applying laminate over it, while it's on the wall. Is this normal? I had the impression it was...
  6. Non-canvas art photo material? (solvent)

    We've had a couple requests for an alternative to canvas for photo art prints. Any suggestions on what material to use for this? We do our canvas art prints mostly on Neschen Monet. Though we just completed a set of streetlightbanners for a local municipality on Sunbrella Vivitex, that came...
  7. washing solvent-printed material?

    What is the proper cleaning approach to wash unlaminated solvent prints? Two years ago I printed some window wraps without any lamination for a customer on our mimaki jv3-160sp, on arlon perf. They lasted great, up until this past weekend, when he washed them with water and dawn. He said...
  8. jv3-160sp timing of "nozzle clogging preventitive function"?

    I can't find this in the operation or maintenance guide, how long is the delay in between the "nozzle clogging preventitive function" running (when the "main power switch" on the back is on, but the front power switch is off)?
  9. JV3-160sp Cyan Overspray

    I'm seeing a lot of cyan overspray on our jv3-160sp. It only shows up on large amounts of print, when I print the test pattern or a small (couple inches) block of color it doesn't show up. It seems to sweep up This just started recently; it's possible there was a head strike, though the cyan...
  10. how to prevent fading with solvent on polyester cloth (neschen versa)?

    We're printing streetlight banners for a local municipality, 36" wide by 42" high with pole pockets (sleeves) at the top and bottom. We're using a mimaki jv3-160sp solvent printer. The plan is to print on Neschen Pure Color Versa treated poylester (7.1oz), printing each side on a separate...
  11. Solvent street light banner material?

    What material do people recommend for solvent printing streetlight banners? These are going to be roughly 36" wide by 42" tall, plus pole pockets (sleeves) at the top and bottom, so they'll be stretched fairl tight and supported at both ends, which should reduce the wind damage. Vinyl is...
  12. Margin of error for materials cost?

    What margin of error / padding do you use for materials cost? We're looking at doing a large (for us) job of 152 streetlight banners. 82 will be 35.5x21, 70 will be 60 x 30, double-sided so we're going to print each side separately. I've calculated out the number of rolls of vinyl we'll need...
  13. mostly idle mimkai jv3-160sp, too much ink?

    We have a mimaki jv3-160sp that we bought used. It's great, though we're having a little trouble with the black head, which I posted about last week (still working on that). However... most of the time it's just sitting around, idle, in standby mode. And it is chewing through ink at a...
  14. Mimaki clogged nozzle: good cleaning trick or stupid idea?

    Hi guys, I have a mimaki JV3-160SP. The black nozzle seems to be partially clogged. I'm working on getting a good photo of the heads (kind of hard to get in there with a camera) but attached is a photo of a test pattern. I've been doing a lot of nozzle washes and printing, but so far seem...
  15. Mimaki JV3-160SP, exact specs?

    Hi, I bought a used mimaki JV3-160SP. This machine didn't come with docs, but I downloaded PDF operations and maintenance manuals. I've been printing on 54" media and I'm considering doing a particular job on 60" media. JV3-160SP_Operation_Manual_V1.5.pdf says the maximum media width is...
