The digital proofing technology is completely controlled by digitization, which has changed the previous complicated printing production process and reduced the cost at the same time. And the stability of plate making and printing quality is greatly improved. In the process of gravure plate making, which does not require film, digital proofing is a more suitable proofing method.
Digital proofing technology is very mature and can fully meet the needs of gravure plate making. The design elements in gravure platemaking are mostly graphics and images, and spot colors are used more. This is mainly because the colors displayed by spot colors are more uniform and more gorgeous than multi-color overprinting, and have better stability. The use of spot colors for highlighted graphics or text can reduce registration difficulty. Therefore, it is critical to evaluate the pros and cons of gravure digital proofing and to verify the accuracy of the proofing system for the restoration of spot colors. In addition to the general four-color proofing technology, the digital proofing technology is also more and more perfect for the support of spot colors. For example, the professional digital proofing system can provide overprinting and trapping of spot colors, control of spot color transparency, Provides a good solution to the problems often encountered in the gravure process such as color gradation transition.
The advantages of digital proofing mainly include the following:
1. There is no need to output films or make plate cylinders, which can reduce costs while shortening the production cycle.
2. Samples made based on inkjet technology are usually 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 and provide 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 document data.
2. The digital proofing system with the function of processing mesh adjustment requires a relatively high cost.
3. Spot colors and metallic colors cannot be accurately reproduced, and a specific system must be used.
Needless to say, 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.
