JV33 printing with white ink..how to do it??
Hi
We have recently been trying to use our JV33 with the white inks. Have not used this before and the machine is basically set up and has two white cartridges installed. However we have needed to do some clear vinyl printing and want to use white. Searched all through the Mimaki Raster Link Pro manual (we use MasterLink Pro 3) for help and tried all the settings we can find but still does not print with the white ink!!!
Help…. sorry if this is a bit basic question…
Can anyone give me a step by step how to set up etc…
Thanks in anticipation..

First thing I would do is check that Rasterlink 3 supports white.

It would seem to… there are references in the user manual and also the ability to select white as a special colour etc

Hi I watched a tutorial on youtube which may help you. Try searching for ‘Mimaki RasterLink ‘Valid Pixels’ option‘.

Thanks Paul…giving that a try now…

Did you get this sorted in the end Phil? My experience of white inks on a Mimaki JV3 was not great at all. In fact I don’t think we have any customers left using it. The RIP is a big part of it obviously. Shiraz did it OK but I would expect Rasterlink to be able to do it better than any other RIP.

Hi.
Yes I did get it to print white but not really satisfied with the results….
ah well…Phil

It depends on the application really. It’s not strong enough to do a solid white unles you triple strike it which takes forever and tends to overink. It’s horrible to the heads and lines because it’s so thick and costs as much as a 440ml cart for a 220ml. It’s a shame because it’s a great concept. We had some great results using Shiraz v6.x for just adding highlights and it’s great for printing onto foil but other than that, it wasn’t worth it to us.
I’m glad you got it sorted in the end though.

What percentages of cover are you using for the 2 white heads. We were told to use 40% when we were shown how to use it but have found that unless we use 100% on each the white is too thin. To solve the running problems of using so much ink its necessary to slow down the print by building in a second delay on each pass in the profile. This slows the print down to a crawl but does give sharp prints with dense whites at some cost though as you are using twice as much ink. Also remember to shake the white carts before use and ideally each day as they are still being cleaned even when not used for print.

This was one of my main concerns when choosing a printer, our white in the AGFA anapurna is very strong very blocking but it has two sets of heads to fire it out to make up for weak whites, (so it is technically 200% white coverage when set to 100% on the slider control). Also the nozzle size effects the density of ink as the white is something that can dry into the nozzles, so they are normally slightly thicker.
Appart from other issues, I have found that the white is okay in our case for window use but it is all down to how many passes and layers it puts down but if you put too many you can effect the vinyl by making it soft and brittle.
However using the white as an Under-white you really want it to be thin and not so white, so there is a compromise.
if I was backing white onto a sticker run, then I would laminate white vinyl onto clear.
