Hi Brenda
You are right - we do go over this every now and then but the subject is
not exhausted yet and new developments are occuring.
Look up the archives under my name and you will find dozens of my posts on
the subject.
I am working with a guy who is an inkjet expert and we are trying to grind
stain and frit fine enough to use in one of the newer inkjets that use
pigmented inks.
The image from the inkjet using the pigment ink will be printed on decal
paper and transfered to the ceramic like a regular decal. At first it will
be like Fords in the 20's "any color you want as long as it is black". OK
that is one way
there are numerous other ways. People have been putting photos on ceramic
with the gum bichromate photographic process for decades. They are big on
gravestones in some European countries.
Another way was announced recently in Germany using the DuPont Cromalin
process with china paint pigments in the photopolymer laminates. This
gives a color image but takes a trained operator and a few thousand dollars
worth of equipment.
Then there is the good old silk screen process.
In the archives you will find advice on how to transfer a xerox or
laserprinter image to the glazed surface or to bare clay bisque. This gives
a sepia image.
I know there are other ways of doing this such as dye sublimation printing
to an organic layer applied to the ceramic after firing. You see this
process in shopping malls in a kiosk where they are selling numerous
objects with the customer's picture on them.
The process used determines the firing temperature. Anythimg from cone 019
for the decals and from cone 04 ox. up to cone 10 reduction for the laser
toner image on bare clay. If you want I will send you a picture of my work
with this process.

Hi! I am sure that this subject has been discuss in the past. However, sense I am new to this list serve, can anybody tell me what the process is for transferring a photograph to one of my pots. I would appreciate any suggestion! I have a university art show coming up and I would like to combine my photographs with the surface of my pots. I usually use B-mix or a very white stoneware for my pots. I don't know if it makes any difference what kind of clay I use to make my pot or not? Also is there a certain type of firing that works best for this method?
Thanks for the help !!

Brenda, I am just about to do that. You might like to try it first:-o and
pass me the result!
Get a cheap computer printer which has fabric ribbon cartridges.
Soak the ribbon with a fine glaze ink of your choosing.
The black on the cartridge fabric will burn away; your glaze ink will stay.
Put the photo into the computer and print out onto ceramic transfer paper.
Then follow the instructions for transferring the transfer onto your pot.
Try it first before doing a boardful!
I am hoping to do this with children's pottery parties. Take a photo at the
party, then put it on each pot that the children have thrown.
In theory this should work with coloured ink jet printers, but we need very
fine glaze ink for that as well as some of the usual printer ink because of
the messages it needs to give to the printer to work. When we have the
mixture right we just need to inject the new liquid into old cartridges.

Hi Brenda,
Here in Northport, MI we are currently capable of transferring EPS
(postscript) files to flatware - ie tiles/platters. Our process is an
automated version of the Kurt Wild decorating process. Where he
uses a dental tool to scratch we use a high speed diamond burr.
Where he uses a brush to add the sulfates (as colorants) to a base
glaze we now use electronically positioned and controlled nozzle.
It is all pretty new but our first work is coming out in bisque just
these days and improving rapidly. Within a 6 weeks or so, at the
Alfred innovation center we shall have a "sistered" machine capable
of working with other materials, such as stoneware. Of course 3d
will be possible when we choose to rotate an axis but for now we
are happy to confront the 2d world and we are improving the process
daily.
Photographs (digital image) can be turned into EPS with considerable
artistic control using packages such as StreamLine by Adobe. Not all
photographs will transfer "artistically" to a lower image/color density
BUT as many artists are aware there are those which (generally, I think
like b&w photos) which get stronger.... one learns to recognize images
that will "take" posterizing and reduction in detail. We let clay be clay
so we need about a four fold increase in size to do much of anything.
Pictures of kids at a party are guaranteed not to make the reduction unless
you want a 20foot X 12foot mural, probably not .
Photographs can incorporate great image density, and because we
use all traditional glazing techniques and such we are not attempting
to achieve "photo-realism". Clearly not our goal! But for signs and
forms of adopted art such as mosaics we can do some things that
promise to be interesting. Soon we hope to begin providing a service
to artists, and hopefully some genuine clay artists, to "transfer" their
work to clay using our process. Signs should be a neat application for
us, as we are set up to decorate 200 (4.25X4.25) tiles at one time, size
is not much of an issue.
Someday, perhaps, a "printer for potters" may make sense from what
we are learning. Running costs should be very reasonable. However,
currently to build machines has been an expensive adventure. There
is no transfer material, or labor. Many of the colorants, like copper
sulfate, are very economical.
Best,
