Metallic inks - poor performance

[born2print]

Hi all, our pressroom is complaining about the Metallic ink we get from <ink vendor>  that actually comes from a vendor of theirs.
The issue is that the rollers buildup crazy fast, like stop and wash every 500 sheets!
Also affects laminate, UV, etc...
So far we are not getting much in the way of helpful responses so I thought I would reach out and see if anyone else is fighting the same thing?

By design, aren't all metallics a nightmare? I just processed a job today that has the smallest speck of metallic 877 and I suggested we just run it 4/c on the copier, I mean digital press because it would be like 487% easier for production, but it's for a university so only the best for them.

Most of our complaints with metallics are from marking when using conventional inks. For most jobs requiring metallics we use the UV version in conjunction with a drying lamp so the metallic dries instantly and prevents marking thru the press. BTW we're using Hostmann inks.

We have a customer line that uses a custom gold and it covers about 75% of the sheet, we have all kinds of trouble with the background taking ink, the ink wearing the plates down etc...have to change the plates about every 20-30 thousand sheets and most of these runs are 100,000 plus runs. Recently the pressroom asked for a new plate and requested the wrong job number and they ran 10 loads like this before they realized the error, sure would be nice to get this figured out.

Always thrilled when banks, colleges, and public entities go through 15 proofs, press checks, and custom mixes of ink. 

Lucky for us, we don't really ever do any metallics. The one we do is for a bank (of course) and it's 871 mixed with yellow, because the dezinger doesn't like any of the Pantone metallic swatches.

We play with metallics all the time with one custy (big name cigar co) and they love heavy 4c blacks. We don't have any issue with plate wear but I know the pressmen are not a fan of metallic jobs. The biggest problem I have is the salesman that insists I have to use custom trapping and other hoops he makes me jump through. I tell him no problem and run it through like a normal job. Haven't had an issue yet.

What jobs are pressmen fond of?

None that I know of...

[Farabomb]

Fair point.

All true, and metallics have their history as tricky, but they have been consistently worse than the usual challenges.
This build-up / viscosity? issue is "new" and I was taking a stab that maybe it was widespread.

te-he, I said widespread  :cheesy:
