How to make Gelli plates for Gelli Printing.

Yes, you read it right, Gelli Printing! Sometimes called Gel plates, Gelli plates or Jelly plates, in this tutorial I share with you how to make flexible printing plates which take colour and texture incredibly well to create exciting monoprints. The resulting prints are worthy of a place on your wall or can be developed further using mixed media - ideal for scrap booking and card making.

This mixture makes enough for an A4 sized mould at a thickness of 1cm

If you are unsure as to whether your mould is too big or too small then test it by pouring 450ml or 1 pint of water into it.


Learn lots of different ways to produce Gelli prints using natural elements, stencils, and black & white photos whilst layering colours and textures. More information here.


200ml / 7fl oz glycerin

250ml / 9fl oz boiling water

20 gelatine leaves




Measuring jug

A mould with a flat, smooth base such as a baking tray, cake tin lid.

Prep time 20 minutes

Setting time 2 hours plus overnight


Rehydrate the gelatine leaves according to the manufacturer’s instructions. Squeeze out the excess water and place in a bowl.

Pour over the boiling water and gently stir SLOWLY until the gelatine has completely dissolved.

Add the glycerin a little at a time stirring VERY GENTLY between each addition. Be careful not to create air bubbles, if you do simply skim them off the surface with a spoon.

CAREFULLY pour the mixture into your mould. If any air bubbles occur skim them off. Leave to set at room temperature for approximately 2 hours. Once set move to the fridge and leave over night, this will make it easier to take out of the mould.

Then you’re ready to use it!


Store horizontally at room temperature between two pieces of thick plastic such as acetate, Perspex or acrylic. Don’t use thin plastic such as polythene or cling film as this will mark the surface.
