Great use of Black & White acetates

Here ten overlapping Black and White acetate prints of faces
give an interesting and successful effect.


 Hi Peter,

Sorry for the delay in replying/sending a photo.
Thanks for your help, they looked great!
Attached a photo for you.

Thanks again,

Acetates used on windows in Pop-up Gallery

Another innovative use for acetates in paler colours than we've attempted before. Thanks to Jack Moolark from United Through Art who used these two large acetates for a Pop-up Gallery in Columbia Road late last year.

Hello Peter,
Hope you're well here are the Snaps from the show.

Thanks again for your help.

All the best,

Jack













































Thanks Jack!

Screen printing with CSM student Josse Pickard


Printing in the studio with Josse Pickard, third year Graphic Design student at Central St Martins. Here you can see his stunning Eagle and typography prints...


Serious concentration - final colour in a three colour print and yes that is a brick on the print table!











































Great Eagle! - very slight miss on the registration.


The Acetate separations, you can see here that our acetate is slightly cloudy. Good for screen exposure but not if you're after clear acetate.

Introducing Petra...

Screen Printing with CSM student Josh Saunders


Screen printing with Josh Saunders (an illustration student at CSM) in the studio last week.  Here you can see one of his incredible fine line illustrative drawings....



A close up detail of the Acetate we printed, some of the lines were as
fine as 0.2mm




















Josh had made a wooden frame and we stretched a very fine mesh on it,
the tension wasn't great but it coated and exposed almost perfectly.




















Printing with acrylic mixed with screen printing medium.




















Getting the number of pulls right was problematic because of the fine lines
- after a few trials we used a textile squeegee which had a half rounded edge.




















A screen stretched under proper tension would have made things easier -
but it's always good to be reminded that you can achieve great things
with basic materials!




















Detail showing the final print - nice work !










Screen Exposure / Part 2 - Expose, wash off and print


Once you've separated the colours in your artwork, your separations are

ready to put onto acetate and then onto screen. If the print is made up
of more than one colour you will need registration crosses on your artwork.
Here are some visuals of a print we were doing in the studio last week
to demonstrate the rest of the process.

The acetate as it was coming off the printer showing the colour separations.





















Lining up the acetates on the screen before exposing them to UV or Metal
Halide light. The black printed areas block the light meaning that the screen
coating underneath doesn't harden. Here you can see the
registration crosses on the acetate.




















Therefore after the screen has been exposed and the acetates are removed,
the screen is washed out and the black areas washed away leaving a clear
mesh (yellow) to print through. The rest of the emulsion coating (pink) has
hardened and the ink will not pass through.
The edges of the screen are then taped to seal any open mesh.





















Once the screen is dry any small pinholes have to be touched up with emulsion,
the screen is again exposed to UV light and then is ready to be printed.
Here printing the first colour.





















Grey ink onto linen, the registration crosses are printed onto masking tape to
register each print.





















Final print colour of four, checking the registration.



















Lifting the screen to see the print after the final colour is printed.





















The final (four colour) print onto linen.
