PRINCIPLE OF RISOGRAPHY
Risography is an ecological printing technique similar to screen printing.
This digital process makes it possible to obtain bright colors and plays with the superposition of soy-based solvent-free inks .
The printing process without heating is very energy efficient
OUR PAPERS
We mainly use
so-called "open" papers
Penetration of ink
is better and drying
more radiant
Range of papers:
Munken print cream 80g
Munken pure rough 150g
Munken lynx 300g
Natural white olin 170g
Artic volume ivory 130g
Colorplan bright white 270g
Colorplan white velum 270g
Citrus Crush 250g
Crush corn 250g
Keaycolour particles
sun dust 250g
PRACTICAL INFORMATION
To obtain the most regular flatness possible, screen at 95%
Check that in grayscale, your whites are at 0%
and your texts at 100%
OUR RANGE OF SHADES
We use 8 base colors which can be layered and screened
The inks are translucent which allows an infinite range of colors
TECHNICAL
Our RZ1070E machine prints 2 colors on each pass.
In risography, imperfections are an integral part of this technique
You will never have two perfectly identical prints. We go back in time with a long drying and the use of creative papers.
The process lends itself particularly well to limited and numbered editions
FILE PREPARATIONS
The maximum print size is 413 x 291 mm and the paper size 430 x 320 mm
Work on your vector files at 600 dpi
For images, you can dither your photos respecting a dither angle 1 color: 45°
2 colors: 30° and 60°
3 colors: 15°/ 45° and 75°
The principle is to divide the number of colors in your image by 90°
Choose the screen ruling according to the desired rendering
Export to pdf each color separately in grayscale by naming each file with the name of the hue
A control file in jpeg must also be attached
