JV3-SP too much magenta

[catalin]

Hello guys.
First of all thank you for youre advices. You sure help begginers like me with some important info, and in my case expensive ones.

My problem is a little bit strange. In all my prints, magenta is over the edge. Black is brown, yellow is orange, and blue is a little bit greener.
This problem appeared from nowhere. Same old Rip (Rlink 5SG) same old profiles, except the ink that is new (same problem with the old one).
I really don't know what to do. "Specialists" from mimaki dont know what is the problem.
Please help, or point me in the right direction.
Tks.

Excuse my english, i had a ruff day with my printer

Start with the Test Draw, to verify that your nozzles are performing properly, and not experiencing cross-contamination. If you are, that is almost certainly the culprit.

If not, then your media profiles (in your RIP) would be the next place I would check. Hope this helps.

Check ICC's profiles you are printing with...

A printing profile tells the machine how to mix CMYK to make colors (and other stuff) so if you want to make red you can make a profile to make it with 100% Yellow and 100% Magenta. so the print will be red..
Also you can make a profile to make the red with 100% Cyan and 100% Yellow, so in the Computer screen when you want to print something red the printer will shoot 100% yellow and 100% Cyan, that merge i think is green, so the print will be green...

80% sure that is profile problem.

thank you for the replies.
First of all i attached one test print, to show you how funky are my heads. I forgot to tell you that my dumpers have almost 1 year from when they were last changed (i ordered 8 new ones today). And a new dx4 head from Asia.
But i'm still afraid that the problem will not go away.

@ Masseria : i'm sorry to tell you, but i'm not that smart to create/modify a ICC Profile. I attached one print screen of my options in Rlink5. However, i updated my printer driver (on mimaki site) and it seems that she's printing a little bit less red. But not her ordinary colors.

Everything seems to work ok, all oiled up like a baby's behind. If you have any other ideas i will appreciate it.

Thank you once again, for your comments.

I dont have a JV3, i have a Jv33. but problems may be fix the same way...

ok i think nozzle is bad. lol. Try cleaning them. And check if you have any drops under the printhead. or any hair... try also to put the printhead in a Nozzle wash for an entire night, so old dry ink can be removed

for what it seems you are using.
BBMMCCYY ink config. (correct me if im wrong)
Magenta doesnt look that bad.. and there is no contamination... so its not a printhead problem...

That rasterlink screenshoot its not where you set profiles.

you should go to:
Print Condition. to select a profile to print with... in the screenshoot you can see how the rip will work... I'd also activate RGB Input profile... so you can print RGB pictures without having problems in color mixing.....(the machine will transform it to CMYK to print).

I suggest you to do this:

I ussually print on Many profiles, depending on the media... but for example in Tarpaulin. (Print condition)
In the Compostion of colors(Color Adjustment) i have magenta set on 30% while Cyan is 90%, because i was having same issues like you have everything was too much Red.
So when i printed... 50% Black (Medium Gray), it turns a gray with red inside...so i have to create a new item in Color Adjustment menu... (Color adjustment menu is part of the profile you select in Print condition for example: If i choose 3m 720x540 print condition... in color adjustment it will apear an item called 3M No-Red (I've created this adjustment) if you dont have any you will see only called Standard/default. Then if i go to tarpaulin in Print condition i will no longer see 3M No-Red adjustment because that belongs to 3M Profile)

If you want to try other profiles you can download them and install it very easily..
Go to :
Start=> Programs => Mimaki Raster Link 5 => Update => Profile Update.

But i think the problem is coming from a color adjustment in the profile you are using...

Attach some pictures of Color Adjustment Menu. And all the menus inside of it...
Maybe i can help you without having to try too much things...

I've try for a month or 2 until i get the final profile adjustment... its a very annoying process but once you got it its prefetct

hope hearing from you soon.

Try this make a few boxes of the colors you listed as being bad make these colors in a vector program must be vector and CMYK.

Once you have that go to rasterlink and set on the screen you posted pure CMYK check the all and set the render intent to realtive.

Now go to the profile screen and double check that your profile is the right one (could have accidentally been changed) on the color adjust tabs make sure you dont have anything adjusted set it all to default and then print the boxes and see what happens.

post pics and let us know. I do believe your having a rip/profile issue.

You could also try downloading a new profile (same one you are using) as yours may have gotten corrupted and try that if the colors are good you can always go in and adjust it a little and the linerization.
