Printing size design
1. Printing size design
In the design of color page printing specifications, A4 size is generally the most common, that is, 210*285mm, and there are also specifications of 180*260Mm, 214*288mm and 184*264mm. However, it must be noted that in the design of color page printing specifications, attention must be paid to keeping enough bleeding size, which is generally 5mm, in order to better reduce the cause of deviation in the case of cutting, required to ensure the printing quality of color pages.
2. Design with color
All colors only apply CMYK packaging and printing colors, and RGB or other color plate identification colors cannot be applied. For heavy tones, the total value of CMYK four colors should not exceed 250, otherwise there may be large color cast and delivery delay or sticky color due to slow drying of printing ink. For light colors, each value of CMYK four colors should not be less than 8, otherwise it will probably not be printed. For gray black text, only use K100 C0 M0 Y0.
3. Photo Design
In addition to being unique, more attention should be paid to the practical significance of color pages, and customers' requirements should be placed in the main parts of color page printing design. In addition, the resolution of the picture must be above 350dpi, so as to ensure that the printed photos remain clear. The resolution of pictures downloaded free of charge on the Internet is generally only 72dpi and is RGB color mode. Be sure to pay attention to CMYK transformation. Color page printing design must pay attention to what problems?
4, Text Design
corldraw making file data, all the text must be converted into graphs, and pay attention to whether there are jumps or overlaps between words, lines and lines. If there are small white dots missing between strokes, please "scatter" them in many ways. In addition, when using photoshop to make text, the screen resolution should be above 600dpi, which is not easy to have burrs. Please use K100 to fill black text, do not use photoshop to preset four-color black filling, and do positive stacking, which is not easy to have white frames.
5. Wireframe design
The total width of the wire frame for drawing the wire frame or setting the border line must be above 0.076mm, otherwise it will probably not be printed.
