This is my second attempt at CMYK printing one of my posters. I had trouble with printing this one, and not because of the image but because of the brown tape I used to mask off each unused image. The tape the print room had been sent was a bad batch and was unusually sticky. Therefore, even once thoroughly blast washing the screen down in the booth, when I peeled off the tape it left a sticky film which turned out to be almost impossible to remove completely. I had to rinse the screen as usual, then clean it with a special screen wash using two cloths on each side and scrubbing. Then rinse it again and wait to dry. Sometimes I had to repeat this process twice, which meant it took me over an hour just to screen print one colour.
I had a second problem, which was that because of the amount of screen wash I had had to scrub with, it had left parts of the screen worn down and the ink wasn't taking through the areas of holes through the screen. This meant areas of the image were slightly blurred, or areas of colour would appear on the image where there shouldn't be any. I managed to eradicate some of the unwanted marks by simply masking over them with tape on the underneath of the screen, but it still wasn't perfect.
I'm not completely happy with how these prints turned out, purely because if you study them you can see the areas of imperfection. However, I realise this is all part of the learning process. At least I now know to double check the tape I am using, and be less vigorous if possible with certain screen wash.
