Printing can perfectly transfer the manuscript to the substrate, but different printing methods also have different requirements for the manuscript. In order to achieve better results, the manuscript must comply with the specifications in order to ensure the quality of printing. The printing factory divides the manuscript into text, pictures, and photographs according to the different uses. For textual manuscripts, the most basic guarantee is to be clear, otherwise the effect of printing will be more vague. Textual manuscripts will have higher requirements if they are for photographic use. Because to take into account the degree of photographic recognition, especially the line painting to be more dark, in order to be more distinct.
The original manuscript of the printing factory for the picture class is similar to the above requirements, but it must pay special attention to the adjustment of the tone. It is best to be suitable for photosensitive materials, otherwise it is easy to distort the printed image, which is very different from the original.
The requirements for photographic manuscripts are more complicated because there are many kinds of images, such as reflection transmission. If all follow one requirement, it is easy for some photos to be printed without the desired effect. But in principle, it is a unified requirement, such as the concentration of colors, not too deep, not too shallow, moderate can be. There must be a certain contrast, but it must not be too large. It must be controlled within a reasonable effect.
The printing factory's requirements for printed manuscripts are all summed up by staff through long-term experience. Practice again and again to know what kind of manuscript printed out the best effect, so users want to print, the preparation of the manuscript should pay attention to these points. Otherwise, it is easy to waste funds and make the printing effect unsatisfactory, resulting in reprinting. Much human and material resources have also been wasted. When preparing a manuscript, make sure it is complete enough to avoid missing pages. Any specific request should be communicated to the printing plant in advance so that the staff can be aware of the operation. Once the original manuscript is confirmed, it can not be changed again, especially when it has been printed. If you want to change, you must inform in advance.
