The final screen printing process was quite simple in the end, and a lot quicker than initially expected. As it went on it became more and more like automatic actions rather than having to think about what was going on at that moment. The first stage was to choose a screen of which was of a big enough size that it could fit the whole of our separations. The next stage was to take the screen in to the stripping room and strip the screen down ready for our exposures. The final step to prepare the screen ready for print was to coat it with emulsion, let the emulsion dry completely and then finally expose the separation through the UV emulsion to dictate the separations on the the screen, after a small wash the screen is ready to print on.
The next stop was to use three pots of screen printing medium bought earlier and mix this with acrylic paint to create the ink for screen printing. This was a very important stage due to the fact that it was necessary to replicate the colours generated in the digital design so that the final designs are in context with the content. The final stage was to use the third pot of medium to devise the hologram effect colour. This was achieved by using a much higher level of medium to acrylic paint to make it as translucent as possible, the colour for the hologram ink was made by mixing silver with a small around of blue, to replicate the effect of the light bouncing off the hologram and changing its colour and then this ink was ready to overlay on the designs. This screen print method was perfect for the visualisation of the hologram effect do to the translucent qualities of the screen printing medium, it replicated the effect perfectly.
Now the final stage was just down to screen printing the actual designs for the banknotes, this required determination and accuracy to achieve the most professional aesthetic possible, accuracy within the overlay printing was they key to realising the balanced and organised designs.
