Vutek QS2 Pro small letters looking fuzzy

[Steven McFadden]

Hi, I am trying to print small white ink text and logo on our Vutek qs2 pro, the smallest text is 4mm high and the larger text is 10mm high, the logo is 33 x 8mm, its all looking a little fuzzy, is there anything i can do to sharpen it up?
I dont know if this is the best forum to post this in, if not could someone point to a more appropriate section?

Try doing a bidirectional alignment, load a roll of 54" material, paper or something cheap that lies flat well.
Print the test pattern bidirectional like the first picture.
See which is the best fitting (lines aligned, best with a magnifier), then enter the value in the bidirectional dialog from the menu Setup in the top left corner depending on the speed ypu print at.

Hi, thanks for your reply! I did all the bidirectional testing before i printed the white ink and some of them were a good bit out, so i got them all sorted but the prints were still fuzzy as the pictures.
I dont know if it could be down to the voltage going into the heads?

That was my go-to, I never experienced a similar problem that bidirectional did not fix, sorry man!
One question, Is it in the scanning or the feeding direction?

 

[Steven McFadden]

I have tried both, one is slightly better than the other

What does the Check Jets say? Is it any good?

 

[Steven McFadden]

Yeah, not many blockages in the white heads

Have you tried printing in Multipass Ultra and unidirectional? add Carriage Speed: Standard also.
I know it's real slow, but sometimes you just need to output that one job.

will give that a go! Cheers

Sorry mate, I gave it my best shot. Good luck to you.

Thanks for all your help mate!

If that was a print of mine (I Have old gsr's and H5's) i would be looking at a white pack there not landing in the right position, not sure how the qs2 pro works but if the issue persists can you turn off individual heads? Try turning half off and seeing if it still blurred? If not it must be one of the "turned off" heads, you can work through this process to narrow down the culprit/culprits and then really focus on those with the Bi-di tests or for this job maybe just leave that one pack off? The smaller the text the more precise everything needs to be, but it looks like just one pack to me so should not be too hard to pin down.
