Picture book printing is the main business source of most printing companies. There are a large number of print catalogues, and the volume of printing is large. The latter process is simple. The main cost of printing business is derived from paper. It is not allowed to make mistakes. When printing picture books, we should pay attention to some basic knowledge.
1. The edges of the text on the printed page print must be >3mm, so as not to be cut when cut. The text must be converted to a curve or a frame. Do not use a system word, if use will cause a white node in the crisscross section of the stroke. The text into curves, please note that the word or whether there is overlap or skip row disorder phenomenon. If there is a white node in the crisscross section of the stroke, it can be processed by the scattered instruction. Do not use color overprint black text.
No, 2 color printing to the screen or printer to print color printing color requirements, customers must refer to percentage of CMYK chromatography to determine color production. At the same time, it is noted that the CMYK chromatography produced by different manufacturers is affected by the factors such as paper, type of ink, printing pressure and other factors, and the same color will be different.
3, the same document print in different times, there will be color difference, color difference degree within 10% of normal (due to ink quantity control each have different, due to large) printing machine, such as the old file to care for this and lose that, printed, in order to avoid the color difference is too large, the number of color codes can only refer to the company the. The chromatic aberration of the printed finished products of different times shall not be used as a reason for the return of the goods.
4, color printing, color color matching color as far as possible to avoid the use of dark or full version of the combination of color, or printing after cutting easy to produce back print.
5, book printing color or shading map of not less than 10%, in order to avoid printing products not present.
6, using the Chinese version of CoreIDRAW9.0 design and production of documents, due to the requirements of the group version, the document designed by the apple machine will be converted into PC format. In CoreIDRAW, images, photos must be based on the TIFF file format, CMYK mode input, not in the format PSD file input, all objects drop shadow images, input separation and transparency, filter material using OWERCLIP coloring, please turn a bitmap in CoreIDRAW (color CMYK32 bit resolution 300dpi, anti aliasing compensation using a transparent background color description is tick). In order to avoid the group edition caused by image mosaic. If the dot matrix is narrowed in the way of adjusting the node, please turn a dot matrix (option, as before), to avoid the partial occlusion when the dot matrix is output. Use the "corelDRAW" filter effects of processed objects also turn a bitmap (options as before), to ensure foolproof.
7. All the input or self - drawn drawings in the design of a picture book can not be less than 0.1mm, otherwise the print will cause a broken line or a condition that can not be presented. In addition, the wire frame can not be set "with the image zoom", otherwise the printing output will form an irregular line.
8, when the object layer was gradually frame precise tailoring, please turn it into a bitmap (with sixth point method), because the placement of frame layer and other object group gradually after rotation, the rotation direction of the gradient together and not. In addition, any gradient objects shall set the width of the edge ", because the output machine interpreted, sometimes causing gradual layer edge coloring problem.
