Silkscreen – About the Basis of Image And Color

2 Comments / Silkscreen, Printing / D Almeida

It is known that color derives from light. The planet is illuminated by light waves emitted by the sun, differentiated in wavelength, giving rise to various colors, which, when seen together, form the color white. The characteristic popular phenomenon demonstrating this reality is the formation of rainbows on rainy days, because water represents a medium with a different optical density than the surrounding air, and light waves refract when they cross the boundary from one medium to another. By refracting white light, the millions of tiny water droplets cause the perception of the constituent colors of light, like a separation of colors.

Silkscreen – About Image Resolution – PPI, DPI, LPI and SPI

3 Comments / Silkscreen, Printing / D Almeida

Unlike the human eye, which captures an image in a continuous, permanent way, graphic environments have tools capable of reaching the image detail, establishing the distinction that separates digitally generated images from mechanically reproduced ones, resulting in two distinct units – the pixel and the dot, respectively. The key issue in this distinction is that the notion of dot is systematically shared across different sources, justifying a clarifying approach to the four resolution measurements relevant to the screen printing context – PPI, DPI, LPI, and SPI. PPI – PPI stands for Pixels Per Inch. The term PPI refers to the image resolution in its digital mode…

What is The Open Source

2 Comments / Web, Software / D Almeida

This is an article that briefly explains the difference between open source, freeware and shareware, types of software that populate the web and operating systems, that we deal with on a daily basis and that we should better understand to help us manage costs and security issues. Generally, Open Source refers to a computer program in which the source code (instructions for that program in its primitive form, in programming language) is available to the general public for the use and/or modification of its original design. Open-source code is typically a collaborative effort, an environment where the programmers involved improve the source…

Silkscreen – Just an Introduction About Image Resolution

3 Comments / Silkscreen, Printing / D Almeida

The definition of a digital image encompasses all genres originating, manipulated, or stored in electronic format – characterized by a strictly visual state, without physical or tangible form. However, in the context of graphic arts, it is common to opt for a pertinent differentiation between digital image and graphic image, considering the direct and significant influence that this difference implies in distinct printing techniques. Following this, the term “digital” ends up being more associated with photographic images or those structured in pixels, while the term “graphic” is linked to flat or vector images. Both types are still electronic formats, but with completely different structures.
