Pre-press proofing types and advantages and disadvantages

The disadvantages of traditional proofing are the following:

1, high technical content, the need for professional and technical personnel to obtain accurate proofs, and labor intensity.

2, need a higher investment.

3. There are many processes involved, the cost is high, and the processing cycle is long.

Third, digital proofing

Digital proofing technology is completely digital controlled, changing the previous complex print production process, while reducing costs. And the stability of the quality of platemaking and printing has increased dramatically. In gravure printing, a process that does not require film, digital proofing is a more suitable proofing method.

Digital proofing technology is already very mature and fully meets the needs of gravure platemaking. The design elements in the gravure plate are mostly graphics, images, and spot colors, which are mainly due to the fact that the colors represented by the spot colors are more uniform, brighter, and more stable than the multicolor overprints. The use of spot colors in the inverted white graphics or text section can reduce registration difficulty. Therefore, to evaluate the pros and cons of gravure digital proofing, it is the key to verify the accuracy of the proofing system's restoration of spot colors. Digital proofing technology not only satisfies general four-color proofing, but also improves the ability to support spot colors. For example, a professional digital proofing system can be used for spot color overprinting and trapping, spot color transparency control, and specialization. Problems often encountered in gravure transitions and other gravure printing processes provide a good solution.

The advantages of digital proofing include the following:

1. It is not necessary to output film or make plate cylinders. It can also reduce the cost while shortening the production cycle.

2. Samples based on inkjet technology are generally more stable in quality.

3, digital proofing is an important part of digital printing, its unique stability can provide standards for the entire printing process, providing a strong guarantee for the improvement of printing quality.

The disadvantages of digital proofing are the following:

1. Some digital proofing systems cannot ensure the integrity of the document data.

2. The digital proofing system with the function of processing the mesh adjustment requires a higher cost.

3, spot colors and metallic colors can not be accurately reproduced, must use a specific system.

Undoubtedly, with the continuous development and improvement of color management technology, digital proofing will show greater advantages in the printing process, and occupy a dominant position.
