Screen printing is a process that I have always been rather curious about and wanting to learn more of. I therefore took the oppurtunity to try a second attempt at the printing process at the university of Brightons printing workshop and studio.
With some added guidance from the tutor in the studio, I regained my understanding of the process and the steps from choosing the right mesh count of the screen, to printing and washing. The image I chose was a simple picture of a tank and a caterpillar ( to be used for an up and coming project) just to explore the process again. I was working alongside another student and therefore, I was able to share a screen together and assist each other if necessary .
Having coated the screen with emulsion, I placed the screen into the drying machine. This meant the screen would be dryer quicker than if it was left to air – dry. Once the screen was ready, my image of the tank was placed onto the screen and secured with tape. ( the tutor advised me to to convert the image into a bitmap for future reference as this would add more detail to the image regarding the black and white areas and would have greater contrast when printing.)
When exposing the the screen onto a UV light machine, it was important to calculate the correct exposure time. This was familiar to me, having used exposure machines for photography and cyanotype printing. Once exposed, the screen is then washed with water which clears any residue and enchances image clarity ready for printing.
Intially, it was rather difficult to know how much ink to use when printing and that a different volume of ink can yield a different results ( This became easier with practice). Indeed, the accidently mixing of water with some ink produced interesting results; creating an unclear and smudge-like image.
I feel my images are not adequate regarding quality, this second attempt at screen printing has been a valuable learning experience, for which I now have a greater understanding of the process and preparation involved. I aim to continue with screen printing using carefully selected imagerey .
