Re: [GBW] Black foil issues
From my experience, as Aaron mentioned, matte white foil is the most
difficult to stamp for solid areas. Second is black foil. It can be
pretty finicky.
As Aaron also mentioned it could be that that particular foil does not
work on your leather surface.
When doing set ups I work with a reject or scrap of the leather on the
same board or card thickness I plan to stamp on. I adjust the temp or
bed of the press as needed (for pressure), or do make-ready in areas
that need it (building up areas on a set up board or piece of plexi
that I can remove to add stops for registration), and I experiment with
dwell time.
If the foil of choice does not work well by itself, I will try using
another foil close in color or texture to make my first impression as a
base or barrier. Actually this is a second impression, I blind stamp
first to even out the leather surface for smooth stamping. If I get a
good impression with the base foil, then I stamp over it with the
colored foil I wish to use.
Generally I find that black foil works best with lower temps. Perhaps
lower temp and more dwell time. However, when a foil does not release
at all as you have mentioned, it usually means it is not hot enough,
that or simply not suitable for the surface you are stamping.
Lastly, I have been told over the years that some black foils have a
shelf life. Have others found this to be true?
Good luck, Julie,

Hello All -
I'm having trouble getting a good impression using black foil
purchased from Talas. Aaron, please chime in if you have
suggestions.:-)
I'm using a custom copper die obtained from Owosso. Previously I had a
magnesium die with the same image and I thought it might be the die
and so ordered the copper version. The die image does have some
intricate detailing, but I still have problems even where the image is
not intricate.
I'm stamping on Harmatan leather, which under all other circumstances
is a beauty to stamp on, using a Kwikprint model 86.
Consistently, the black foil simply doesn't stick to the leather. I've
even tried applying glare on the image area, which is not needed with
gold or silver foil. Testing with gold foil yields expected results,
so I've narrowed the issue to be the foil. I've tried temps of 250 to
300 to no avail. Also, played with dwell times and pressure.
Thoughts, suggestions?
