Ink Smearing on Mylar Sheets

[black95gt]

we just plotted a couple of sub-division plats to Mylar and are having a problem with the ink smearing or not drying. We used to spray a film over it to stop this. Does anybody know what this spray is called?

Thanks
Andy

In the old days I know a lot that used simple hair spray for it. Most god
art supply stores should still carry the higher priced spray and NO I don't
know the official name of it.

That sounds like it should work pretty good (the hair spray) but i am wondering if it would be sticky afterwards or if it was to ever be in a situation with a lot of humidity?

Andy,
Something like a Chartpak brand Workable Fixative?

I think we'll use the brand Krylon Workable Fixatif. This can be bought at Michaels craft store which isnt to far from the office.

That should work just fine.
Make sure you use it with a lot of ventilation (I recommend outdoors!).

yeah, it worked well and i wish i woulda done it outdoors. I had a headache and was nauseated all afternoon. We even went and did it in a different office. But it turned out well. Thanks

In the past I've always used Krylon.

I'd bet those mylars do not meet the requirements of the agency you are submitting to. Ink flaking or smearing will be
a problem in a couple years when other mylars rub against them.
You might throw some water on the dried product to see if it does anything.
Proper mylar on an inkjet will dry quickly these days, so your ink may not be soaking in right.
Its better to catch now than have to replot a year from now when the agency notices a problem and is considering you for
future work. You WILL replot them for free in that situation, and look worse than if you do it now.

We have done several of these over the years and have never had a problem after we spray the filatif on it. We have all of our old Mylars in a seperate drawer and there is no sticking, discoloration or any other cosmetic problems. I have to firmly beleive this is the proper way of doing this as this is the way we have done it in the past as well as with all of the people that have recomended using the filatif. I just forgot what this product was called since it has been a couple of years since we have used it.

the issue is the smearing. If the ink is not drying in the timeperiod you are used to, something has changed.
I've seen this happen when mylar for electrostatic plotters is used in inkjets.
So its not the fixative in question.
I actually never realized people used fixative on ink/mylar, i thought it was for pencil/artistic stuff.
The ink should stand on its own in my experience. Guess one more layer cannot hurt though.

You've nailed it James.

It all depends on the agency you are submitting to, and their requiredments. Oregon law used to require "archivable" quality submittals for survey plats, which most of the County Surveyors interpeted as Black India ink on mylar. If you look at a museum's idea of "archivable", though, a good H pencil on a high quality acid free velum is "archivable" to 400 years or better with proper care.

Just recently, the survey community here has had a problem, because one of the media acceptedable for filing plats sudenly became unavailable (I think it was the mylar). I'm not sure of the resolution - I've lost track of that conversation, since I'm doing more engineering now than surveying.

If you're going to use the fixatif, make sure your agency is ok with it.

There's a side note on this issue as well in the Survey / Civil field, and that concerns the "archivability" of electronic field notes and survey data. Field books and pencils used to be the only way of recording data and I've researced some field notes over a hundered years old. I wonder if anyone now could go back 10 years and recover their field notes taken in a Sokkia and recover the survey???? Anyone sitll have access to their notes taken in DOS & transfered to DCA field pack?

We battled this for most of last year and into early this year. We were
using a product from a specific manufature for many years even decades, then
all of a sudden the ink stopped adhearing to the mylar. It would never 100%
dry. The manufacturer finally admitted that they had changed the formula and
the problem was their doing. They then said they had went back to their
original formula. They sent us some cut sheets and rolls of the stuff. The
ink would dry and stick pass a smear test then about 2 mnoths later we got a
call from a local municipality that they pulled a drawing we had submitted
and the matte was actually seperating from the paper and the ink was flaking
completely off.
