Re: [PPLetterpress] Here Here to inks!
- I too have bought out some shops and inherited many cans of ink. Funny how
cans of ink often outlive their owners....
Here's my two cents: I have used all kinds of inks that were initially
designed for offset or other methods of printing and they work just fine. As
always, one is better off running a test on an unknown ink/paper combination.
At worst, its just an extra washup.
If the ink is hard and doesn't want to spread easily (this is especially true
of old rubber based ink) dispose of it. Ancient oil ink will usually be hard
right to the bottom of the can. Old metallic ink will often not print true to
color. I've been told this has something to do with the metal flake used
tarnishing over time.
I've used some soy inks and they have been fine on uncoated stock. I can't
say what they would be like for halftones or on uncoated stock.
I would not recommend mixing inks from different brands, etc. Ink is cheap
enough in the grand scheme of things.
Hope this is of value.
- Greetings all,
In the book arts studio at Arizona State University I use Gans Small Press
Rubber-Base Inks (mixing black #RBP010) for all letterpress and polymer.
Rarely do I have trouble with ink transfer from rollers to polymer to paper.
On the occasion that I do (humidity, but mostly dry here in the desert) I
add magnesium carbonate to the ink to tack it up.

- I use Dan Smith inks on polymer plates without a problem. Highly
recommended, in fact.
It sounds to me like you have your inking rollers set too low. Any
extra pressure they exert on the face of the type will squish the ink
out to the edges, resulting in hollow, bloated type.
Because plastic does not wear at the edges like lead type, the face
of a polymer plate is more unforgiving to low rollers: the
rounded-ness of a worn lead letter will disguise the squeezing effect
of the roller. In fact, you need to drop the rollers to ink all the
worn parts of the face. On polymer any variation in roller height
sticks out because of its extremely flat face.
Or, equally likely, you have mounted a polymer plate on a base that
lifts the face of the type above type-high. When the base was
machined, poor tolerances of thickness or flatness could now cause
parts or all of the plate to raise above type high. Check with a
micrometer or type-high gauge to see if this might be the case. You
need to make sure that you are mounting your plates on a surface that
is as flat and even as your rollers and cylinder/platen. Maybe you
could share what type of base and plates you are you using.
If you find variation on your printing surface due to a poorly
machined base, you might consider purchasing a Boxcar Base, whose
thickness, flatness, and parallelism are all guaranteed within
0.001", and will never raise a plate above type-high. You can find
out more in Boxcar Press's catalog at www.boxcarpress.com.
Is this helpful?

- Hi Brian,
I agree with Harold. He beat me in responding. I was about to write to
suggest you use a type-high gauge to check the height of the polymer and
backing together. Sounds to me like the inking rollers are hitting the
surface too hard -- leaves a halo effect, weak inking in the middle of an
image with extra ink around the edges. I have had no problem with Van Son
inks on polymers except this exact halo when don't adjust for one irregular
backing I have. Best regards, Tom

- Dear David
On the cylinder flatbed I use 36 point rule as roller supports running the
length of the press bed for both metal and photopolymer. These run fairly
close to the rails to prevent ink stray (on the printed paper).
Like your idea. Probably more practical with the hand press? You could also
have sets of these made, at various heights of plate thickness, to test how
each might work with your particular inking practices, and with different
kinds of forms, type, solids, etc.
Let us know how it works out.

- Harold's comments on roller pressure are striking a raw nerve. I print on
an iron hand press and have been planning to print some polymer plates using
a magnetic backing. Has anyone had any experience in using roller bearers
with polymer plates? I have been considering getting some long polymer
strips made up about 1/4 inch wide which would be the equivalent to 18 point
rules. These could be positioned on the magnetic backing to serve as roller
bearers. Has anyone else tried this?
- Dear Fritz,
I would like to buy (at least) three of these one pound cans of
Hostmann-Steinberg dense matte black inks. Do you have a minimum order?
I have purchased from your company as both an individual (Turkey Press) and from
my institution (Department of Art Studio, University of California, Santa
Barbara) but it may be best if I just sent a check in advance or gave you a
credit card number. I'll follow whatever payment method you recommend.
Do you carry any other inks?
We have a few hand-outs from NA Graphics, but not much appears to be up-to-date.
Since we have Vandercooks at home and at the UCSB campus, I'd like to know as
much as I can about what you have around or in stock.

- Harry--The minimum order is $10.00, so no problem here. We have other oil
inks, which are all letterpress based formulas, it's just that the
Hostmann-Steinberg is by comparison a superior ink. Our regular job black
works fine for most ordinary work, and once in a while, a gloss black is
desirable, which the H-S ink is not.
Our latest catalog is dated 1999, and prices have been changed mostly. We
have added the Bunting magnetic bases for photopolymer, at good prices, and
have been recasting ATF type--Garamond, Bulmer, Goudy Oldstyle, Engravers
Roman. The Vandercook list in the catalog is just the surface of what we
have, and since we have the Vandercook blueprint file, we furnish parts all
the time made to special order. And we can find almost everything else.
I'll just go ahead and process this order and pay from the invoice which
will be included with the package, usually in the plastic envelope that has
the UPS shipping label. My business partner went to UCSB, (and graduated
from UC Davis) so he'll be happy to hear his old school is buying something.
