In the case of color printing, packaging box manufacturers should pay attention to what kind of specifics. Color printing is not just simple printing in 4 colors under normal circumstances. There are many overseas consumers who often appear in their journals and magazines. The color collided by the sample spot color is very much a type of magenta color. This color is the most difficult to adjust. In addition, many consumers will use the spot color, or after printing, on the basis of color Increase the number of black printing inks, and always keep the color of the mixed color. The packaging box manufacturer reduces the color brightness while also reducing the chroma. Generally speaking, in the four-color printing technology, the color of the picture is the most important thing to pay attention to. There is a problem. Therefore, packaging box manufacturers must attach great importance to the color problems in four-color printing.

To make color design, you must pay great attention to the following four aspects:

01 hollowed out

There is a line of blue characters pressed on the yellow bottom plate, so that the specific position of the blue characters must be empty on the yellow plate of the film by the manufacturer of the packaging box. The opposite is true for the blue version. Otherwise, the blue things are directly printed on the yellow, the color will change, and the original blue characters will become green.

02 Overprint

There is a line of black and gray words pressed on a certain red bottom plate, so that the specific location of the black and gray words does not need to be hollowed out on the red version of the film by the manufacturer of the packaging box. Because the black and gray can be pressed against any color, if the specific content of the black and gray is hollowed out, it is a part of the smaller text content. When printing, a little error value will cause the white edge to be exposed, and the contrast of black and white contrast is more Large and very easy to see.

03 four-color black

This is also a relatively common related problem. Before outputting the contents of the packaging box manufacturer, it is necessary to routinely check the black text content in the publication file format, especially the small print, whether it is only on the blackboard, and should not happen on the other three-color plates. If it is present, the quality of the printed product will be discounted. When the RGB plane graphics are converted into CMYK plane graphics, the black text content will definitely be converted into four-color black. Unless it is a special setting, it is necessary to deal with it before the content can be output to the film.

04The image is in RGB mode

When the image content in RGB mode is output, the RIP software system generally can automatically convert it into CMYK basic mode content output. However, the hue quality will be greatly reduced. The finished product printed by the packaging box manufacturer is light in hue and not bright, and the actual effect is very poor. The image is most suitable to be converted into the basic CMYK mode in photoshop. If it is a scanner manuscript, it is necessary to go through a process of color correction before the image can be applied. Many friends do not care about the RGB and CMYK formats when making file formats in PS.
