Assignment 2: Screen Printing Stage 2 and 3

Stage 2 and 3: Screen Printing Techniques:

I explored the idea of using lines to create texture with gelli plate one afternoon. The idea is to make a rich background pattern using lines. Can I re-produce them with screen-printing? With gelli plate you can mix colours enables you to layer colours in one print however you cannot repeat the process and reproduce same pattern easily. On the other hand screen-printing is about precision and repeats. But layering colours is not a simple task. I found some mesh, nets and knitted pieces to use as templates to emulate the effect.

I decided that I am going to use several techniques of printing suggested in the textbook and maybe some more.

Method 1: Using existing templates for screen-printing:
Fist things first: I prepared my chemical water, print paste and thickened Procion MX dyes in bottles with small nozzles. Following Benn and Morgan’s (Committed to Cloth) advice I prepared a batch of cotton cloth soaked in soda ash. So the “fixing agent” is in the cloth not in the dye. Apparently this extends the dye to be used longer then a day and I do not anticipate finishing it all in one day.

After the first day of screen-printing at home, I can easily say the results are a good bunch of failed attempts. I am trying to cheer myself up thinking: “I can use them as background to future projects.”

I guess the mesh, nets I used were very thin. Not enough area to have a definitive print. The knitted fabric I used for template soaked up all the print paste, hardly any transferred to the cloth. The texture is transferred on the back of the screen but not to the fabric. I had to lift the template and press the cloth to the screen (like a gelli plate) to get a print. Result is ok, but technically not screen-printing.

Method 2: Acrylic paint Permanent Designs:
Next I tried to use acrylic paint to created a permanent pattern on the screen. For this I bought some mesh and stretched it myself onto a picture frame. I used the gelli plate again to transfer the design onto screen.  After waiting a day for it to dry I am ready for printing. It was looking promising until I stated printing. The acrylic paint disintegrated during the printing (maybe I applied to much pressure with squeegee) or I didn’t fix it the acrylic paint properly. Disappointing!

Method 3: Breakdown Printing:
I decided to try “breakdown printing” described in Benn and Morgan’s book.  Using the thickened dye paste (Procion MX dye mies with print paste - I used the recopies in the course book ), I scribbled directly onto the back of the screen and left it to dry. It created a pattern/texture which will be disintegrating slowly during the printing.

Much better results and finally some progress. I also continued scribbling directly onto the cloth



Method 4: Vilene Stencils:

I made two templates of Vilene. It took me good 3 days to paint the templates themselves. I am going for more natural organic forms, softer lines for this one.

Vilene soaks up a lot of print paste and it requires some strength with pulling with squeegee. First template was too ambitious. I didn’t even get a proper print from it. The leaf template was better but I got weak prints. I wanted to do lots of repeats, increasing the darkness of colour I used. There was a lot of ghosting and smudging. I didn’t persevere. Another failed attempt! I think for this method you need to aim for your design well before execution. It isn’t easy to control and trying to work with precise designs is not a good idea. But for me the problem was not getting a strong print. It looked pale and muddy.


Method 5: Cut out method:
I started using pigments and a ready bought binder for this method. I cut out templates from paper  for printing. This is a really good method to print at home. However, template is too fragile and not usable after several prints. I had a few backup templates cut-outs to continue printing to layer prints and colour. Making multiple templates can be laborious however worth the effort I think. Otherwise you only produce a plain print.

I decided that I am going to use this technique but with sticky back tape, hoping it will last a little longer.

Method 6: Exposed Screens: 
I did a short Screen-printing workshop with Victoria Williams at Ochre Studios near Woking. We worked with exposed screens using photo emulsion. Ochre Studio has great facilities, which I don't have at home.  However access is limited, only Tuesdays and Saturdays for members. The first image I used is a rose sketch, I did at the workshop. This was the trial run.  Second image is sketched at home with more consideration.

We made several prints using pigments, discharge paste, and metallics. I liked the discharge method the best. You can get some definition around the outer lines of your pattern. While the colour is lifted off it emphasises the outline of the design.


But I am worried that I will not be able to replicate this at home.
