Why? Stop and 4! (what aesthetic neobhodimist if enough chatyreh?)

NATA NOVA, you are silkscreened with the offset will not be confused by chance? This is in offset printing all color shades are transmitted four colors, as used for the halftone grid. At the same silk-screen grid is almost never used (although this is partly possible, but with a fairly significant limitations). 64 colors is used to transfer colors and halftones.

Incidentally, even in offset printing, there is not a 4, and 7 colors - to obtain higher quality images with high color gamut (color range) and high color saturation. True, there are serious difficulties with separations under the seven-color printing, this requires special software which is developed and comes with a seven-printing equipment for printing. That is, color separations for a print in the usual way in Photoshop is not done. The same, incidentally, and 64-color silk-screen printing - for color separation used specialized software, very expensive.

No, not confused. Nature abhors advisable. Screen printing is a manual press. Can and more (than 64) colors are mixed, but I do not see any practical or estetecheskoy expediency. Absolutely all the colors obtained by mixing 5 colors (which replaces the white white paper). You can print other 4-name colors, if color paper
One of the main (or black) then you just need to add white paint .. AND ALL!

I apologize, but as a professional in the printing industry can only say that what you wrote, it is impossible to realize in silk. Therefore, multi-color screen printing and do differently, and not, as you propose.

Mechanism of silk is extremely simple - the places that should not be stamped, closed, and the rest is fed paint. And so many times, until ready image.
In the second half of the twentieth century, introduced the term "seriography" to distinguish handicraft production, production of posters and T-shirts-on creation of works iskusstva.Stali produce sieve cells are a thousand times smaller than that of silk and fine colors .. colors in this technology is not limited. How many nuances According to the authors - many times the material will fall under the printing press, which is the same time pour the paint on it .. seriography distinguish from computer-prints is easy - passing her hand over the surface roughness and feel sherohovatosti.kak on plain film.

   I do not understand you. You do not understand me ... I think I'll answer my work. (And you, my!) 4 tracings long wait, only to make the grid and print .. What to say without pictures? Bury .. As soon as I will do so immediately and show.

Since that speech, and that a single run is printed one color. If you want more colors, you need a few runs and some paints.

In contrast, the traditional offset for 4 runs (in fact it is usually a single run in a four-printing machine) - each of its color (cyan, magenta, yellow, black) - provide all the color palette. Theoretically, a 16-odd million colors for a raster cell of 16x16 pixels (each paint gives way, 256 halftones, and their mixture - 256 in the cube colors - this is 16 with a few million). Fourth, black paint is an additional, reinforcing black. Again, in theory, any color and shade of color, including black, can be obtained only by mixing three primary colors, but in practice this black print in this way could not be obtained, and therefore use more black paint.

Here are two words theory of Typography.

As for the silk-screen printing, the raster it is little used because of restrictions on the minimum size of playing the point, so halftone raster usually do not transmit, publish "clean" colors. Hence the need for a separate paint and a single run when printing multi-color images for each of its color component.

Fair to say that sometimes all the same in the silk used raster. For example, multi-color overprints (labels) CD-ROM or DVD and make silk-screen printing, with a maximum frequency of the raster to 133 lpi (raster lines per inch). However, the practice must say that the print quality obtained with this is worse than when you print the same image offset, moreover, that the offset can be printed on the CD with lineature (frequency raster) and 150 lpi, which gives a better image detail.

You can get gray ( "brother" black, not black)

I would call (in this context), black paint (color) (as white) principal, (bazovychi) because without them nothing will come ...
Black paint-color (and white, which performs the role of paper, if it is white) .. change the tone (lighter-darker) and saturation (bright-washed), all other colors formed by the three major (true-red, yellow. Blue)

Shl: I do not think that I cheated Tallinn specialists, awarding 4 tracings (for nets) for silk-screen printing technique on white paper with multicolored works ...
Simply "principle" of offset printing is the basis for this particular sample ..

With offset, I know in theory, but because of its practical trouble with color can be assumed that of these 7-mi, one will be sure to paint a very black, and 6-for 2varianta yellow. red and blue?
