For printing, while not having access to a press machine like working from home, an option could be using a homemade Gelli plate. For starting a low–tech Water-based monoprint I made my matrix by gelatine. I think a 1 cm thick matrix should do the work. Following is the recipe I used:
1 tin of gelatine 100g
2 ½ cup of boiling water
1 mixing bowl
1 flat-bottomed metal tray
1 piece of rag
First: pour half a cup of boiling water into the mixing bowl.
Second: slowly sprinkle gelatine powder onto the bowl and mix it with a spatula.
Third: add a cup of boiling water to the mixture. Make sure all lumps are dissolved.
Fourth: add another cup of boiling water and mix.
Fifth: put the rag in the sieve, hold the sieve above your tray, then pour the liquid into it. That helps to filter lumps and bubbles if any.
Sixth: use a piece of newsprint to skim across the surface, dragging bubbles to the edge.
Seventh: put the tray into the fridge shelf. Make sure to get the tray as level as possible.
Eighth: after 6-12 hour it will be fully set and ready to use.
Cover your Gelli matrix with a plastic wrap to prevent it from shrinking too much.
You can Keep your Gelli matrix in the fridge for two weeks.
If your Gelli matrix got damaged, put it in the microwave and reheat it to a liquid, then pour again into the mould.
CAUTION: DO NOT ATTEMPT TO USE HOT WATER AND TIP DOWN SINK - IT WILL BLOCK YOUR PIPES
Use a rag and water spray to clean the matrix as the last touch.
