The following is information sent by Barbara Minor concerning her Riso
Screen Workshop at Ravensdale.
It includes some of the specifics of the class and goes into better
detail about required materials.
Letter sent to registered participants on 7/29/98
I have some updated information and homework for you to do prior to
arrival at Ravensdale '98. This all should make the time in
the Riso Screen workshop MOST productive for you.
1. The catalog description said that you would be able to make "2
screens in the class and more in the lab". This is true if you
do not do the preparation of materials and Xerox images prior to arrival
at the workshop. If you do have the time to prepare ahead of
time, I have ordered enough materials for you to make up to 4 small
screens and 4 large screens at the fees listed in the catalog of
$3.00 for a small screen and $5.00 for a large screen. If you would
like to "reserve" a specific number of screens, please contact me
materials and bill ready when you arrive. If you think you would
like to make more than 8 screens - time permitting - let me know so I
can order extra materials.
2. The lab session will be in the evening of the day of the
workshop - you may make as many screens as there is time and
materials for in both the class and lab. I am also willing to be
available with the machine at other times that are mutually agreeable
during the conference - time, materials, $$ and space availability
permitting. Again, if you think you would like to make more than
the allotted 8 screens (4 small and 4 large) - please let me know so I
can order extra materials.
3. The process for making a Riso Screen for screen printing is
quite simple and direct (involving no photographic equipment, materials
or processes). You must simply have a high contrast image (black and
white) and access to a Xerox machine. The rest happens when the
screen and the Xerox (together) are put through a machine that will be
sent to Ravensdale for your use during the workshop. I am
hoping that by giving you some more specific information ahead of time,
that you will be able to accomplish more during the
workshop by doing as much preparation as you can prior to your arrival
at the workshop.
Please bring with you Xeroxed images - of your own original
designs/drawings or of found images and patterns from other
sources. These should be high contrast / black and white with no gray
tones. I understand that there is a copy machine near the
classroom - how near or how much it costs is not clear. Also, if
everyone needs to Xerox their images....there will be a long line for
the Xerox machine and you'll probably not get as much accomplished as I
know you will want to in making Riso Screens. So, bring
alot more Xeroxes than you think you'll need or want to use to make Riso
Screens for screen printing.
To develop some really wonderful patterns from your own
original drawings or "doodles" - start with a high contrast original,
reduce your image, repeat it many times, combine it with copies of
itself and re-Xerox the combination. Please note screen interior
dimensions listed below.
Your image can also be from many of the "clip art"
resources. The fun, for myself, comes when I start Xeroxing those
existing patterns, cutting them apart and combining the cut parts with
other parts from other patterns....thus yeilding a new pattern
I have ordered the necessary items for making the screens
(fabric/frame/adhesive). They are being shipped to Evergreen
State College and will be ready for you to use immediately during the
workshop and lab. AGAIN, if you want to make more than the
eight screens (4 small and 4 large) that I have ordered for each
participant...please contact me ASAP. The fee for the screens
covers the materials and the cost of renting and shipping the machine.
Interior dimensions for the screens are - small = 4 3/4" X 5
7/8" at a cost of $3.00 per frame
large = 5 7/8" x 8 1/2" at a cost of $5.00 per frame
4. It is my guess that most of you will want to use the workshop
and lab time to make as many Riso Screens as possible-
rather than spending your time actually doing the screen printing. I
could be wrong...and if you want to come prepared to print as
well as make screens - that is your choice. There is a feedback loop
that occurs in image development...you make and image, you
screen print it and realize how you want to make the next image
differently. Also, I am willing to give critical feedback and do some
trouble shooting if you run into problems while screen printing. Three
hours will fly by and I want you to accomplish as much as
possible so you can work with this process after you leave the workshop.
5. I have done a considerable amount of experimenting and find
the following - acrylic screen printing mediums work the best in
combination with the Riso Screen and a Fimo sheet of clay. The brands
that I particularly like are
Golden - Screen Printing
Createx - Monoprint Base or
Lyntex Transparent Screen Printing Medium
Most all acrylic mediums will work - they all have different working
properites and end results after baking onto the polymer clay. All
of the mediums I have indicated are easily mixed with powdered
pigments. You can also use pre-mixed Acrylic Paint or Acrylic
Screen Printing Inks. I have found that the Liquid Sculpey Polymer Clay
reacts with the Riso Screen in a way that makes the
screen difficult to clean - so, I suggest you plan on working with water
based screening mediums during the workshop.
6. Another suggestion - to increase your accomplishments during the
workshop...if you are going to do any printing, please have
your polymer clay already conditioned and rolled into sheets that are
easily transported...you can re-roll and cut to size your sheet
at the workshop.
7. If you have questions - please either email me at
10:30am-5:30pm Central Time....or at 504-929-6964 between 7:30pm and
9:00 pm. I will be working on many things and may be in
and out of the studio/home....please keep trying...I may not be able to
call you back at a time you are reachable. Today (July 29th)
only - I will still be in Indiana and can be reached via email or at
812-265-2430...please keep trying...we are in and out alot as we
prepare to go back to Louisiana.
Thank you for registering for my wokshop. I will do everything I can to
make it a productive and fun time for everyone!!!
Additional Information based on quesitons from Linda Greer and noticing
that the supply list included with a confirmation packet was
Polymer clay used at the conference in the Riso Screen Class.... It
is probably easiest for people in my classes to bring their clay
unbaked - conditioned and rolled into sheets that are easily
transportable. The sheets can then be re-rolled at the conference
according to the specific needs at the time. I have used settings on
the pasta machines from the thickest to the thinnest and had
good results. Obviously, the thinnest sheets are very delicate.
Concerning the colors to prepare - or should the sheet already be
patterned or varigated or "not a solid color"...bring what you would
normally gravitatte towards. That way we can all see what
different clay surfaces will yeild. Baked sheet can also be used...sizes
should be appropriate for experimentation and a little smaller
than the screen sizes listed above.
A sheet of CORIAN and some waxed paper works well as a surface to
support the clay while printing. There is some question (in
my mind) as to locations for baking polymer clay while at the college.
Ventilation is a concern. When the Acrylic Screen Printing
Mediums are dry the unbaked/screen printed clay can be transported
without damaging the surface to be baked later/elsewhere...
If I understand the response to my workshop correctly...people will
want to make as many screens as possible during the
workshop and work with the screen printing and baking later...like
evenings in the general work area?? We will be having the class
in the Screen Printing Studio - printing will not be a problem during
the class...provided space allows for drying areas
Here is a complete and correct list of materials for the class -
included are needs for making screens, screening acrylic mediums
and baking the clay.
- MULTIPLE - like lots!!! of xerox images of pattern,
texture, images...this should be what you are interested in, they should
be high contrast/black and white...bring whatever interests
you realizing that the xerox machine where you are is probably
cheaper and easier to get to and you won't have to wait in
line when you'd rather be making screens - examples are
xeroxes of you own drawings or of clip art...anything you
can think of will probably work. Bring more than you think
need. I have found that people in this workshop sometimes
like sharing or swapping images.
- polymer clay - sheets, any color, ready to roll to desired
size and thickness at the workshop - these may also be sheets
you have made into patterned surfaces - they must be flat.
You can partially bake, form and rebake according to your
- Acrylic Screen Printing Medium - available at Art Supply
Stores - see above for brand names
(note that this is replacing Liquid Polymer Clay -
reasons suggested above) - to be used with powdered pigments (below)
- Powdered Pigments - of any kind that you know of. I have
purchased some from Sinopia in S.F. http://www.FoundCollection.com/
and Douglas and Sturgess, Inc in S.F. (1-888-ART-STUF)
(to be used with Acrylic Screen Printin Medium above)
- Instead of the above two items you can simply use
pre-pigmented Acrylic Paint or Acrylic Screen Printing Inks from your
local art supply store
- to refine the size/thickness of your polymer clay sheets
you'll need your pasta machine - again, condition your clay a
- tracing paper
- roll of waxed paper
- sharp scissors
- exacto or matt knife
- graphite pencil / eraser
- SHARPIE Marker - thick and thin
- "White Out" or any kind of white correction fluid - brush
or automatic pen will work
- paper for sketching or notes
- 12" steel ruler
- clear packing tape (instead of transparent tape)
- Silk Screen Sqeegie - 4 1/2" and 5 5/8" long
"Speedball" makes inexpensive squeegies that are
sold in art supply stores. They are plastic and *** and are
cut with a saw. Bathroom shower tile squeegies also
work - as do plastic pastry board scrapers. Basically you need
somewhat flexible *** or plastic squeegie to drag
across the screen to push the ink through the screen.
- Any tools you need for working with the polymer clay
Again - call at the numbers/times above if you have questions. See you
