1, the graphic color mode must be CMYK or grayscale.

2, if you need a large area of pure black background in the color map, it is recommended to use K :100, C :30, such black printing is brighter than a black color, and because the existence of the blue version can make up for the black printing false loopholes. Of course, this value is not fixed. I used to make a poster with K :100 and C :80. This is because the area is too large and the printing press is fast. It is difficult to make the color solid, so the value will increase accordingly. Also, if there is a warm color pattern on the entire figure and the edge is feathered, or there is a warm tone transparency, the value at this time is adjusted according to the actual main warm color tone, such as K :100, M :60, Y :70, This pattern transition is very comfortable and not as weird as it was at K :100. This phenomenon can be seen in the PHOTOSHOP test.

3, on the variegated pattern anti-white or anti-white thin lines. When choosing fonts(or the number of pounds of lines), pay attention not to use thin fonts such as imitation songs and fine circles, and try to use bold letters, official script, and other lines that are obvious in order to avoid the possibility that the set will not be correct and the text or lines will not be seen. clear situation.

4, do small hanging cards and other things that need to roll the box, punch holes, should be careful, try not to design the outer border. Because if there is a slight deviation in the plate position when rolling the box, there will be a situation where one side is large and the other side is small.

5, the design of newspaper manuscripts, offset paper printing should be noted, newsprint and offset paper are more ink eating, so, in addition to paying attention to the number of mesh when the film is released, but also pay attention to the corresponding reduction in color when making, such as making newspaper manuscripts. You need to see the grayscale of 30, so when you make it, you set the grayscale to about 24, so that printed on some gray newsprint, the actual effect is equivalent to the grayscale of 30. The offset paper is whiter than the news paper, and the adjustment color can be lower than the normal copper printing, and it is higher than the newspaper manuscript, depending on experience and feelings.
