PATTERN Preparation

Precise sample preparation is key to quality reproduction with conventional printing technology. The lesson explains in detail the methodology of sample preparation, from design, definition of the smallest unit of design (repeat unit) to color separation, which is carried out in three different ways, depending on the complexity of the pattern.

It is recommended to visit this site where tutorials for applying features of Corel Draw in pattern preparation for screen printing, can be found.

The video shows a simple example of color separation of a pattern by the method of classical (individual) color separation or effects. In the language of printing, this method is also called "SPOT color separation". This term actually means that the sample is divided into defined colors, and these already defined colors will be used in later printing. The number of these colors is defined by the pattern and can be as much as the configuration of the printing machine allows.

Contrary to the "SPOT color separation" methodology, the so-called "PROCESS color separation", which refers to the raster separation of colors, ie the breakdown of the sample into parts of the four primary PROCESS colors - CMYK, by mixing which any color palette is achieved. Only four colors are always used in this method, which means that 4 screens, meaning 4 stencils are always prepared for any sample.

• PROCESS Colour Separation

In addition to PROCES Colour Separation, this video is demonstrating the principle of process colour mixing (CMYK) and the and the gradual construction of the image, ie its three-dimensionality and plasticity, ie photo-like structure.
