Trying to get a true BLACK color - Mimaki JF 1631 moving comment

Tekkie, thanks for the input, my tech has since left and he was not real up to speed on the Dual CMYK set up. All I know is right now I have a good test draw on all 8 heads and everything is good I am just not sure if the bottom row of carts are printing or not. I guess we never saw a place...

I must have completely misunderstood what dual CMYK meant. Based on earlier conversations on here, I was told it would allow me to print at a lower pass rate with higher quality results and your method does not suggest that at all. I am not sure the advantage of your method...usually what I do...

I guess my question is how do I get all 8 heads to fire if I am only in CMYK?

We print on wood and aluminum but would be more concerned about making it right for aluminum. All 3 of my machines are on rasterlink, but for dual CMYK to work do I just use any CMYK color profile? What will make all 8 heads fire? I was under the impression if I use a CMYK color profile then...

Hi Tekkie, this helps a bit but what profile do I want?

Hello, My tech is on site and we have finally changed my JF 1631 over to dual CMYK and now we need detailed instructions on how to set up the color profiles for this. We have rasterlink, can anyone help? I would really appreciate your time. Jay

We are needing to get rid of a JF1631 Mimaki with no working heads, do any of you out there know if it would have any value or be worth listing on ebay? If not what can be done with it? Metal scrap yard? Dump? I do not have the room for it but figure there might be some value at the metal...

Thanks Bgraphics, I lowered the head and things got better, problem is my media is not always 100% flat, better buy it flat though huh?!? Thanks for you help

If someone could advise me as to why I am getting magenta over spray every time I print. I have attached an image. What would cause this.

Thanks for the response....Can you elaborate a bit on the newer inks. Can they be run through the JF 1631? Do you have a vendor for them?

We have a flatbed mimaki JF 1631. I am looking for a a way or an ink, or coating that will give ink printed on wood a longer outdoor life. I have hear 3 years but no longer, is their something that can be done to extend this? Possibly a UV coating that can be brushed on or sprayed on or a...

I would like to find a list of technicians in the USA that service the Mimaki JF1631. It would be nice to have a list of people that do this. Thanks

I swapped to heads on the same machine and when I went to start up I got this message system halt: 11d:pcb SLRLY-F1 I am being told the JF Interconnect is blown, is that right and I am also being told that my bad heads will blow it every time is starts up. I was unaware that I had bad heads...

artbot, the head alignment guide is helpful but is using the tool fairly easy? I am still trying to figure out how it adjusts the head.

sent pm, thanks artbot

Any response on this?

Does anyone know of a good source for the steps to replace a printhead in a mimaki jf 1631? I have the alignment tools and a fairly good video for doing the replacement but I was wondering about the initial steps and then also what to do once the head is install. Do you have to run cleaning...

Hello, I would like to move a good head from one of my 1631 machine to another machine. Do I need to order the tools to fine tune the alignment for the head from mimaki? Any help would be appreciated?
