What are the benefits of using soft proofing in printing houses, can you introduce it?

It is well known that the color of traditional proofing printing is extremely unstable. Not only that, in terms of cost, the traditional proofing is even more expensive, and it is in this context that digital proofing was born. Today's best digital proofing machine I personally think should be the Injielong CMS full-process digital output system carefully manufactured by Good Impression Company.

The reason why she is the best is because the printing ink it uses is a biological pigment environmentally friendly ink, which can effectively avoid the color deviation caused by external factors, and it supports soft proofing, which greatly saves expenses to a certain extent, and the color of its printing is pure and realistic. If the landlord wants to know more about soft proofing, you may wish to take a look.

There are two main purposes for proofing:

First, check the quality of the original. For example, whether the reproducibility of the tone and color of the original manuscript meets the requirements; Whether the layout size, images, text arrangement, rule lines, etc. are correct, whether there are any omissions, etc., and if there are any inaccuracies, they should be corrected.

Second, it provides samples or basic parameters for formal printing, such as ink color, the range of dot reproduction, etc., so that the printing can achieve standardized and standardized operations.

Proofing methods can be divided into two main categories. One is hard proofing, such as mechanical proofing, photosensitive material proofing in pre-proofing, inkjet proofing, etc. The other type is soft proofing, such as screen display.

A mechanical proofing: the use of printing materials and the printing environment are often inconsistent with the actual printing, the sample obtained from the proofing machine is always different from the original color, reproducibility and the printing sheet obtained on the printing machine, in order to reduce this, the difference has been developed multi-color automatic proofing machine, and applied to printing production.

Second, the pre-proofing method.

Pre-beating, no need for printing plates, paper, ink and proofing machine, but the use of special photosensitive materials, the application of optics, photochemical principles, to obtain color samples or display with the display screen, to find problems in image information processing, timely correction, improve the efficiency of mechanical proofing.

1) Proofing method of photosensitive materials.

This method includes color sheet stacking method, color layer stacking method, and electrostatic proofing method. Generally, the photosensitive substance is coated on the substrate of the sheet, and then the corresponding color separation and mesh negative are closely attached and ** to make a monochrome yellow, magenta, cyan, and black film, which are superimposed together and combined into a color image. It is also used to transfer the coloring layer of each monochrome film to the proofing substrate to form a color proof.

2) Computer-aided proofing method.

This method has soft proofing and hard proofing.

Soft proofing, using a computer-aided color proofing system, can see the color image on the display screen, but cannot obtain the sample.

Hard proofing, using the data output of the color full-page imposition system, the sample is obtained on the hard proofing system. The hard proofing system is generally composed of a display terminal, a keyboard, a floppy disk drive, a laser recording system and an online developer. It is also possible to obtain samples from the data of the full-page imposition machine through the color inkjet machine.

3) Electronic proofing method.

This proofing method is mainly adapted to the growing color desktop publishing system, using an inkjet printer or a dye sublimation printer to obtain proofs.

In inkjet printers, a thin nozzle is installed on the print head to spray ink onto the paper. There are a variety of models such as four printheads, three printheads, and one printhead.
