HP UV pigment prints, black easily scratched!
Hi,
I am having trouble with UV ink using a HP Designjet 3500CP.
Am printing onto HP Universal Instant-Dry Photo Semi-Gloss Paper. Q6579A
Prints beautifully, but the black is particularly susceptible to scratching. Colours seem ok.
I dont have any trouble with the dye inks on it, or with the UV ink onto backlit material, only the photo paper!!!
The last roll I used suffered in the same way and I was hoping that the problem would go away with this new batch.
Anyone have any suggestions as to the cause of the problem please (?)
Regards, Roger

Hi Roger
I’ve also got a HP3500cp using pigmented inks but I have no problems with scratches normally.
But on one of my medias, stop light rollup display, I had problems with dark colours scratching until it dries out fully. I was just careful with it until I can laminate it but sometimes the little star rollers leave marks.Try a different media as I think it’s the coating on the media.

Thanks for your input. I wondered if the problem was due to not being dry enough, but the problems I’ve had have been after leaving it dry overnight before handling. Maybe it does need longer.
The media is supposed to be ‘instant dry’ … but that is just a name. 😕
I should soon have some other media to try, so when I get a chance I’ll do so.
I’m also investigating my options for laminating as that should solve my problem plus add extra life to the prints. How do you laminate your prints?
Another thought I’d had was that the printer was putting down too much ink, particularly black, and so that makes it more susceptible to scratching.
One thing that struck me as odd, was that when I fitted UV inks to it for the first time recently, the menu in the printer changed.
Now instead of options to select eg “High-Gloss Photo” or “Opaque Vinyl” when I load a roll of media, I get options like “UV Custom Media A” … or B, C or D, as well as a couple others, but no photo paper (!)
My problem is that I cant find a legend for what the Custom Media A,B,C or D is actually for.
I’m sure I’ve seen reference to it on the spec sheet for some HP media in the past, but since needing the info to make sure I’m selecting the right profile, I’ve not been able to find it, despite hours of searching.
The prints have been turning out fine, colour wise, just the issue with the black.
Well thanks again.

Roger, are you sure you are using the right media? Reason I ask is because I thought the coating for Dye and Pigmented inks was different so you would need a different coated media for the UV inks.

Hi Martin,
Yes, I’m quite confident about that.
Some of the media I have is not suited to both (according to HP’s spec sheets), but the ones I am having trouble with are definitely listed for either ink system.
Thanks for pointing it out though.
Regards, Roger.
