In printing, although the increasingly sophisticated technology of graphic information processing has brought more and more advantages to the puzzle books printing manufacturer, various manuscripts from different customers cannot fully meet the printing requirements. The common "font missing", "graphic resolution is low", "document editing garbled", "color Settings do not meet the requirements of printing" lack of links, and size is not well met in printing problems.

With the opening and socialization of the puzzle books printing manufacturer process, more and more designers are making manuscripts and participating in the puzzle books printing manufacturer process, which has caused a very serious problem. Due to the lack of professional printing training, many people lack the necessary printing knowledge, the designed manuscript can not be reflected in the back of the printing, or can not be realized at all, the printed matter deviates from the designer's design intention, so it is difficult to print a good print.

So let's look at the puzzle books printing manufacturer and do the little things that are easy to overlook, "color" and "image."

The first color above: when making plates, the original manuscript is also divided into blue (C), magenta (M), yellow (Y), black (K), color drawings or color photos, and there are thousands of colors on the screen. It is almost impossible to print these colors in one color. The printing plant uses a four-color printing method, that is, the original manuscript is first decomposed into green, magenta, yellow, black four-color plates, and then printing and then color synthesis. The so-called "color separation" is based on the principle of subtractive color method, the use of red, green, blue, three kinds of filters of different wavelengths of color light has the selective absorption characteristics, and the original manuscript is broken down into yellow, product, blue three primary colors, in the process of color separation, the color absorbed by the filter is the complementary color of the filter itself, so that on the sensitive film, the formation of black and white image negative, and then add screen, Enough to turn negative, after copy, print into a colorful plate. This is the principle of color separation in photography.

Due to the development of printing technology, the color of the manuscript can now be separated, sampled and converted into digital information through the puzzle books printing manufacturer scanning technology, that is, the color of the manuscript can be decomposed into red (R), green (G) and blue (B) in the same way as photographic plate making, and digitized. Then the digital information is decomposed into blue, magenta, yellow, black and four-color information by mathematical calculation.

The next step is image processing:

The common point of graphics and images in design is that they can form visual information and have "graphic" characteristics. The difference is that graphics focus on describing and displaying the shape characteristics of the object, while images focus on reflecting the face of the object. In computer processing, graphics are generated according to the graphics algorithm and stored with the relevant parameters of the image, through the computer calculation drawn straight lines, circles, rectangles, curves, geometric graphics, engineering drawings, CAD, 3D modeling, etc., these graphics are based on the model, function, parameters, algorithms, etc., with "vector" characteristics, so called vector graphics. The feature of large vector graphics is that the file is small, and there is no distortion whether it is enlarged, shrunk or rotated.

When the color and image are designed in the early printing stage, the line width of the outline line should not be less than 0.1mm; The width of the negative line should not be less than 0.12mm. Too thin, resulting in broken lines, loss or unclear pictures during printing. If the image is not handled properly when compressed, it will also cause image distortion, resulting in obvious jagged, which is also a noteworthy way.
