Thermofax-Printing "quick&dirty" unleashed

At first the result, size 29 x 40 cm, 5 colors, 2 rainbow-prints:

The complete Thermofax-Print, size A3.
And in this way I began:

The CopyPrinter-Master size 20 x 42 cm, with tape at the small edges.

Thermo-printing with the Brother CJ-723.
The Master is mounted on a paper. Printig upside down.

The first color (lightblue), printed in 2 tracks.

1st track of the 2nd color (dark blue).

Now both tracks are printed in dark blue.

3rd color: rainbow-print of green and brown.

4th color: rainbow-print of brown and black.

...the 5th color is black.

And the last color is copper:
Situation shot: printing copper-metallic.
The copper-color-print of the fish.
Some new experiances:
> with the Brother PJ-723 it is possible to burn "infinity" CopyPrinter-Masters, in the width of max. 21cm. I use only 20cm, because the angel of retraction must be very, very 90°.
> When burning the Master, it becomes longer... and more length, when getting wet by color and streched by the squeegee, and I'm talking about cm!
If you want a matching of the different color, you should swage the picture with your program before printing on the Master.
> Printing with metallic-colors... is not so easy. This time I printed the "salmon" several times, with drying inbetween with a hair-dryer.
The color sticked the Master very quick, so I used for every picture a new Master-film, because the material is very cheap. If you have only one burned Master, you better wash it out.

Nevertheless, it was a very good experiance with the "quick&dirty" thermofax-printing.
Now I know, how I can print very quick in very big sizes...
Ok, Andy Warhol did it before, but he used the "complex" screen-printing-system.

I wish you nice celebration-days... with large prints ;o)

Thermofax-Printing with a CasioWriter CW-16

The CasioWriter CW-16 without ribbon.

Just reading in the manual about the CasioWriter CW-16, that this typwriter works without ribbon, "when thermal paper is employed". Wow - so I used it with my Gestetner-Copy-Master, mounted as usually.
& here is the print:

Ooops, the words are mirrored, when printed.
Ok, lets try to use the Copy-Master from its backside:

Ok, I wanted to write, " have to print on clear..."
It works ;-)
The back-side-print has more fringe edges... but this small letters are good readable.
My tip for your next invitation-card: use an old thermo-typewriter for the text.

printed from the usual side

printed from the back side

Have a nice time, when printing your x-mas cards...this year with pics & words (poems?)

Thermofax Printing with Brother Pocket-Jet 723

I know, this thermofax-printer (max. A4) is not cheap, but make it able to print directly from your Mac/PC.

PJ723, Thermofax-film mounted on a 80g/qm-paper, size A5.

Additional the driver offers you the possibility to use a very fine screening.
Sorry, I using a german driver.
The result are speckles, you know from an ink-jet-printer, very fine... so fine, that it is not easy to adjust the paper under the Gestetner-thermofax-film.
Now I make the first print on an fixed transparency, under this I adjust the paper I use for printing.

Here is the result from my 1st 4C*)-thermofax-handprinting:

4-Color Thermofax Hand-Printing, Postcard.

Here you can see the speckles the driver makes.
Happy printing

The Brother PJ723 likes it very clean, but when printig on the Gestetner-Film the plastic-surface evaporate.
To keep the Pocket-Jet clean you have to make one, ore two PRINTS on simple, clean paper.
*) 4color-seperation made with Photoshop.
Ok, after printing you can see nothing on the paper, but you can feel the plastic on the surface of the paper.

Thermo-Fax-Printable Metallic-Acryl found.

Some times befor I wrote, that it is not possible to use in this special thermofax-print, metallic-acryl-colors. But now I've found a printable acryl-color:

It's on you, to test the colors you like... good luck ;-)

Ooops, sample forgotten: results with pure black/white pictures (no shades of gray ;-)

This time I'll show, how I make a "blind-embossing", a print without ink, but with a lot of pressur.
The clicheé I've etched with FeIIICl in Copper.

an old screw-press

the copper-clicheé

Postcard, face to the chlicheé

the cover is closed

the carriage under the press, after a lot of pressur... can see the relief on the back-side

Hope, you enjoyed this little lesson. If you've any question about, please write.

Quick&Dirty Thermofax, some Trouble-Shooting

A. At first I thought, that the Riso-Master has the same qualities, then the Gestetner "CopyMaster.
But it is not...
This Thermofax-Screenprintig is only possible with the Master-Film from Gestetner!

1. Just I' ve tried to make a "Gestetner-Master" with a bigger black area. The copy-machine became to hot, and the "Riso-Master" wrinkles.
It helps to use a black paper as carrier (it takes a part of the heat), and to screen (80%) the black area.
Additional, you should start with black areas, when the copy-machine is still cold.

2. Metallic-colors. They are not printable. The pigments of this colors are too big for the "Gestetner-Master".

3. Cover-tape-frame. I don't use it anymore. So the waves, I make while printing, become flat after every print. "Riso-Masters" with tape-frame became more wrinkles after printig a while.
And now I use less pressure, while printig.

Hope this will helps you

PS. I' ve tried some fonts. "Gill sans", normal, 9 pt, or bigger, works fine.

PPS. I've 2 of this Tattoo-Copy-Machines. Now, after some days useing them, one has a slack joint. The result are stripes in the motive, when I don't "kick" the machine.
The other machine becomes too hot. That means, only lines can be copied, without wrinkles...
...shall I buy a third one?
Still, I love this thermofax... The results are sooo 70th ;-)

Cheapest Thermofax-Screenprinting "quick and dirty"

I suppose, you know the basics of screen-printing and/ or Thermofax-Screenprinting.If not, please take a peak to the many videos about at youtube.

Thermofax-Screenprinting is not new, but I suggest,  the way I've found out, is the cheapest and quickest of all.
Do you know "Risography"? It is a kind of digital thermofax-screen-printing. Also used from Gestetner as "CopyPrinter".
And on your way throug the "bay", you shurly have seen the cheap Themofax-machines used as Tattoo-tools.
This are the both things I use for my thermofax-printing.
The Gestetner Copy-Master-Film ist often seen for USD 15.–/ 100m x 0.23m.
The Tattoo-Thermofax-machine you can get for about USD 135.– (or equivalent, in Europe).

Now you' ve to calculate: 100m x 0.23m are about 300 Screens in A4!
I use this technic mainly for A5 / A6 = Postcards, that means 600 or more Screens for USD 15.-

The Thermofax-Machine is... made in China. The nice LEDs are only fake, but ist works in its simple way, and that is, what we wont for this little money.
There is a similar Machine with USB-Connectiv, but I've not used is up to now. It is only for Windows. I'm Mac-user.

Handling Thermofax quick and dirty:

1. Draw your image, or print it out in the size 1:1, only black and white.
You can use Photoshop to raster an imagine, you can use also 4C-Prints.
2. Prepare the color. For printing on paper, I use Acrylic CMYC-Colors + Black / and Lascaux-Retarter.
For printing on fabric (T-Shirts), use the colours you have.
3. Prepare the print-base. I use a glass/acryl-glass with marker for the right position of the paper.
Then I'm attaching the Riso/Copy-Master -Film directly on the glass.
4. Mount the Film on a carrier of A4-paper, as seen in the pic.
5. Copy the imagine with the Thermofax-machine on the Film.
6. Print and enjoy your art.
6a. For printing, I use a window squeegee, cutten to the right size.

Now I'm curious about your work. Would be nice, if you mail it to me:

Happy printing
