Bob’s Your Uncle!

scribble 5 dark strokes

A while back, I was walking along the street in the city centre and noticed a load of strange squiggles on the pavement.

scribble 4 dark strokes

It’s handy having a decent camera on my phone – how times have changed – so I took a few snaps.

scribble 1 ink spatter

The squiggles had been made by a machine that scrubs chewing gum off the pavement – ychafi! I downloaded them when I got home and had a bit of a play in Photoshop and Bob’s Your Uncle!

The reclaimed silkscreen

Some time ago I bought some second hand silkscreens. They had photochemical stencils on them and needed to be cleaned so that I can re-use them. They had been originally coated with Speedball Diazo photoscreen emulsion so I had to use Speedball’s remover.

I poured a little remover onto one side and quickly spread it over with a small, stiff nylon scrubbing brush. I turned it over and did the same on the other side then let it stand for one and a half minutes, no more as the screen remover mustn’t dry out. Then I scrubbed both sides with the brush before scrubbing again with hot water pouring onto it, making sure to get into all the nooks and crannies until it was perfectly clean. Then off into the garden on a sunny afternoon to dry. And ready to use again.

Health and Safety notes: I used protective glasses, thick rubber gloves and old clothes.
