The silkscreen studio finally reopened, I printed the last layer of the four-color posters I am working on. I'll post pictures later, for now I am posting the posters I printed in January. The idea was to conceive a picture made of gradients on photoshop, with all the spectrum of color, to decompose the picture in the four layers, Cyan, Magenta, Yellow and Black, to apply half-tones, and then to "play" with the four stencils in silkscreen. If you consider that there are four variants in four color process print (CMYK), if you permute the stencil, still printing with these four colors, you get 15 different posters [arrangement of a number of quantities in every possible order, according to Collins dictionary]. In order to avoid the moiré pattern, printer have achieve to create the perfect combination of angles in the halftones, so Cyan is printed with an angle of 105 degrees, Magenta 75, Yellow 90, and Black 45. So when you overlap them, you get a regular rosette. The picture was compose with very few black, but a lot of yellow, which means that when the black was printed on the yellow stencil the poster was very dark, and the yellow printed on the black stencil, disappearing in the poster, too pale.   ¶ 00:02
