Corso a colori

Color Engraving Course



The Color Engraving Course is structured in three intensive modules of a high educational level, for a total of 160 hours , held by Maestro Manuel Ortega.

It is an exclusive of L'Armadillo , the various techniques of the color course are inspired by the research and studies of Masters who invented or developed the procedure. Maestro Ortega learned them directly from them or from their collaborators, over time he transformed and refined them according to his experience, to make them more usable.
Five color printing methods are taught, grouped into three distinct modules . It is also possible to attend a single module.


The three modules address the following topics:

• Lost matrix iron engraving · 40 hours

• Multi-plate color engraving · 80 hours

• Hayter method in color + Collography in color and carborundum · 40 hours


Read below the costs and a brief description of the techniques.

Lost matrix iron engraving
The technique of color engraving on lost iron matrix was presented for the first time at the Armadillo in 2016 by Maestro Pere Pons who perfected the method. The technique involves the lost matrix engraving on an iron plate. The print is made with the overlap of the three primary colors.

Multilayer color engraving
Multilayer color engraving is a course consisting of two methods: the additional method and the subtractive method.
The additional method is based on the use of three plates which, after being engraved, are inked with the three primary colors. This allows to obtain polychrome prints in which the chromatic overlay generates a very wide range of colors.
In the subtractive method, the three plates are granulated to obtain a rough surface that generates a print with maximum color saturation. Subsequently, by lowering the grain, the light parts are obtained and rich tonal gradations are returned to the slabs.
The two techniques can be combined with each other to obtain results with greater shades, shades and color contrasts.

Engraving by the Hayter method
The color etching method created by the painter and engraver Stanley William Hayter is based on the processing of several plates with etching at different layers of depth. The dry printing technique involves the use of modified colors spread with rollers of different hardnesses to obtain tonal variations and interesting chromatic overlaps.

Engraving with the method of color and carborundum collography
Collography is a versatile method that gives the possibility to create a series of experimental matrices obtained by using different materials. The prints are characterized by the free use of colors that generate unique interweaving of colors and refined shades.
