disclaimer: i am not a gocco expert! i have tried to do a few different things, and i have learned a little bit in the process, but i have a lot more to learn.
there are a lot of great gocco resources out there that i will list at the end of this post, and are very helpful. i just wanted to make a simple tutorial to demystify the pg 5 gocco for someone starting out. any comments, corrections, or suggestions are welcome.
make sure you have inserted your 2 AA batteries (you can see where they go in the above picture), included in the pg 5 basic set.
NOTE: if you are using a photocopy, put the blue filter behind the master and insert them together.
at this point the order is top to bottom: yellow flash hood; clear plastic window in the gocco; blue filter; mesh master; original artwork; blank paper; foam bed.
put both your hands on the front of the gocco (the picture just has one of my hands, because the other one is holding the camera, but you can see where your hands should go).
push down (you will see the the flash and hear a crackling noise) and hold for 3-5 seconds.
when you remove the yellow print hood, be careful not to touch the bulbs until they cool.
replace the clear plastic layer and and put the inked master back into the gocco the same way and position as before. if you haven't removed the flash hood, do it now.
now the order is: clear plastic window in the gocco, clear plastic sheet over the ink, ink, mesh master.
put whatever you want to print on on the sticky grey foam bed. now it will be helpful that it's sticky as it holds your prints in place.
close the gocco to make a print. *repeat.*
this technique above can be used to print on paper or fabric, although to print on fabric, you need to used special gocco fabric ink. (EDIT: you can print on fabric with the same kind of screen and same process that you can use to print on paper-just use 'gocco stamp ink for fabric').
another way to print on fabric is instead of using the hi mesh master (which can be used for both paper or fabric printing), use the gocco screen masters especially for screen printing on fabric. with these, you can't use the gocco to print, rather you use the gocco to make the screen, and then print like typical screenprinting, using gocco screenprinting ink, which comes in jars and is not the same as the 'stamp ink for fabric' that comes in tubes.
cleanup:
the screens can be re-used many many many times. you can store them in a ziploc bag in the fridge and take them out when you are ready to use them next time. this way, you don't even have to clean off the inks.
the fabric inks are water based. i recommend taping the cardboard edges of your screen before you start, that way they won't fall apart or warp after cleanup with water.
you can use the gocco cleaner with the paper inks, but they will also wash off if held under running water (this is where the tape comes it). you can also wipe with a sponge or paper towels. keep in mind that it's important to clean the print area only, and it the screen is stained in other places it will not affect your future prints.
current situation:
several years ago gocco' s parent company riso announced that gocco's would no longer be exported to the united states. this caused a bit of a frenzy and lead to creation of the save gocco campaign. EDIT: after several years of limited supplies, it seems that gocco will indeed be ceasing production in the next year or so. supply availability is not clear for the long run, but there are people working on getting a u.s. company to take over production, and other people working on developing supplies and systems that will work with the gocco machines. this author is optimistic that the gocco will live on.
