SOS Roland amidoinitrite?

Good Day Signmakers,

I am having a problem with a print I am trying to get out today. Maybe you guys can help me out. Oh this is my first post so Hello to everyone!!!!!

The colors are coming out a darker (purple). The problem is more persistent in raster parts of the print.

Pic info:
I have attached a pic. You can see at the top I have a head test print, to the left is the print that I am getting (Roland), and on the right is the color blue I need( HP Deskjet 3845)

What I have done:

1. I have taken the file into photoshop and tweaked colors and I am unsatisfied with the print when I adjust channels, contrast, color balance...
2. Cleaned the heads.
3. printed the file on my desktop printer which turns out really nice.
4. saved out as eps, pdf, tiff, from adobe illustrator, photoshop, and FlexiExpert.

i think that there are enough missing nozzles that your prints are already shifting it's color output. you might want to fix the missing nozzles first before messing with the color settings.

Your nozzle test looks like crap. Get all the nozzles firing and see what kind of results you get. If the colour is still off, you could try using some different profiles.

Question(s) for you ...

Your nozzle test looks like crap. Get all the nozzles firing and see what kind of results you get. If the colour is still off, you could try using some different profiles.

Can this be caused by a bad head? Will bleeding the lines fix this? Are Roland heads replaceable by us, or is tech mandatory? Will 3rd party inks cause this?

Thank you!

The color looks like you probably took an RGB image and converted it to CMYK somewhere down the line which is a lot more restrictive colorspace when it comes to blues. Try to work with an RGB colorspace right up until you get into the RIP, it will be the best at colormatching RGB. Versaworks will accept jpg images even, so check and see if the image is in RGB and bring the jpeg right into Versaworks.

Your nozzle output does look pretty horrible, the big chunks is kind of worrying, however in theory you'd get a few pieces of blue that look correct, and a few pieces that didn't from where the nozzles didn't fire. I know my Roland SP300V gradually lost the ability to print Cyan and Yellow. It turned out to be the pump, which I guess the first generation ones really sucked bad (or didn't suck at all I guess!), was under warranty though and got excellent service getting it replaced, the company switched out wipers, dampers, etc.
