Today I figured out how to print my Gocco pattern "tile" in multiple repeats, using a home made registration plate. In case anybody's interested, I thought I might document the process. Here it is!
My home made registration plate, made out of some polypropylene from the art store. It's the same size as a Gocco screen, but you'll notice I've cut an indent out of the top edge, leaving two little tabs sticking up at either end.
When printing onto this plate, I made sure that it's edges were lined up with the edges of the screen. None of this printing is done using the actual Gocco machine by the way... just my modified squeegee method - I'll explain that later.
Okay so here's the registration plate positioned carefully on the paper so that it continues the pattern. (I'd already done a few tiles at this point before I decided to take photos).
Here's a delicate bit - the edge of the screen is placed down on the paper so that it's touching the top edge of the registration plate (being careful not to bump the plate).The two little tabs sticking out of the top of the registration plate sort of fit under the curved corners of the screen.
The registration plate is removed, and the screen is slowly lowered down onto the paper (being careful not to let it slip around). The indent cut out of the registration plate means that when lowering the screen from a standing position, it lands exactly where the registration plate was, rather than slightly higher.
To perform the print outside of the machine, I ink up the screen as normal, cover it with the transparent film, and use a hard piece of plastic to squeegee the ink back and forth. Probably not very "screen friendly" but it's the only way I can think of. Other suggestions are welcome!
The final product. Not perfect, but I suppose that just adds character :)
