The relationship between printing quality and excellent color separation

The problem of color separation is due to the pre-press production staff or ink supplier, but finds other reasons. Through a better understanding of the relationship between manuscripts, films, stencils, and printing shops, there is greater confidence and confidence in the resolution of color separation problems, and more profit from them.

To have an overall concept

There is an old saying, "Fruit and bean seed," and the separation is the same. If the original manuscript or scanned image does not pass, then the result can only get worse. Common problems include:

1. Low file resolution

2. Originally stored in JPEG format;

3. The image has been transferred from RGB mode to CMYK mode;

4. The image is based on an inappropriate ICC color profile;

5. Images are scanned from prints;

6. QuarkXPress or Illustrator documents are loaded with a large number of EPS files that have different attributes;

7. The files put in come from different software versions, and the program uses different color management parameters.

All of this puts you in an unfavorable situation because it is difficult to determine which factor degrades the quality of the color separation film. This makes too many factors in the management of production processes uncertain.

There is no clear answer to the resolution of these issues. Printers may have to say that they have to work in accordance with the principle of what to do. Although this is true, if you do so, you should not complain too much about the problems that arise and you may not get the best product quality. It may be possible to edit and correct each file at a relatively high cost, but often this does not help.
