Gelatine Printing

Gelatine printing is a form of monoprinting in which a gelatine slab is used as a printing `plate’ in conjunction with standard water soluble printing inks/paints to create images. Very little pressure is required to make monoprints using this technique – no press is required. Basic materials brayer/paintbrushes slab of glass for ink rolling paper/ […]


Gelatine er et naturprodukt af animalsk oprindelse. Det fremstilles udfra kollagen, som er er protein og en vigtig bestanddel af bindevæv. Gelatine kan derfor udvindes fra hud, sener og knogler. Omdannelsen fra kollagen til gelatine består i en ændring i molekylets struktur, som f.eks. vil ske ved opvarmning. Gelatine er i modsætning til kollagen vandopløseligt, […]


Take a look at the image of a square next to a circle. When the circle is mathematically the same height as the square it appears to be too small… to counteract that the height needs to be increased slightly so it looks correct to the human eye. This height increase is called ‘Overshoot’. see […]

irradiation phenomenon

Inverting files isn´t always straightforward: As you can see from the image above when black on a white object is reversed we experience what’s known as irradiation phenomenon, whereby the white version looks 10% larger. To counteract this illusion, it’s important to slightly reduce the overall weight of the logo.

Recipe for Pure Rice Starch Paste

1) This neutral pH rice starch powder is made from glutinous rice, so mixing and cooking it on the stove is not necessary. If your tap water has a high mineral content, use distilled water instead. 1. Place 3 tablespoons of rice starch powder in 1 cup of boiling water. 2. Stir briskly with a […]

Nori – Rice Starch Paste

Nori Nori is very important in the Japanese style of printmaking. It works as a dispersing agent to give the ink body so it will spread evenly over the block. Ink without nori can look speckled when it is printed, often an unwanted effect, while ink with nori prints more uniformly. Traditionally, it is also […]

kento registration

The kento is a simple device by means of which the printer insures the register of the picture throughout the printing process.
