What Is The Difference Between Flexo And Rotogravure?

CI flexo printing (Central Impression flexo printing) and rotogravure printing are two areas with significant differences in printing technology, especially in many details. Next, give us an in-depth comparison of the effects of these two printing technologies:
The first thing to clarify is the definition and determine the corresponding operation process.

In CI flexo printing machines, when we say "CI", it is actually a simplified representation of the words "Central Impression", which symbolizes the central impression process.
The function of the central printing cylinder is to ensure the stability of the position of the materials throughout the printing process and to fix them in the middle of the printing.
By utilizing multiple printing devices to ensure that the rotating material in the center print cylinder is accurately locked, we have successfully achieved a high degree of positioning capability and repeatability.

The gravure printing process has been practically used in rotary gravure printing machine equipment.
To perform printing work, it needs to be achieved by the mutual rotation of the printing roller and the printing plate roller.
In the printed version, excess ink is completely removed, and the impression roller is used to apply just the right amount of pressure on the surface between the two printing plates to squeeze the ink from the grooves onto the content to be printed.
2. Involving the performance and use of printing

The printing quality is excellent, the operation efficiency is high, and it exhibits excellent stability characteristics.
This technology has been widely used in the packaging printing industry, and is especially suitable for mass-produced items with high precision requirements and high material carrying capacity.
This type of packaging is mainly designed for printing food and beverages, packaging materials for medical items and drugs, and packaging of household cleaning and cosmetics.

It has the ability to print high-quality pictures and fonts, and is extremely suitable for large-area printing work.
Compared with CI flexo printing, seals usually present a more refined and high-end feel. However, such a design will undoubtedly increase the cost of its production.
This method is ideal for items like banknotes and boxes that require high definition quality and superior printing.
3. Developed models and related information

The entire process of drawing production includes multiple links from the initial draft conception to electronic color separation or photography, to the creation of positive and negative patterns, reverse exposure, main exposure steps, as well as cleaning, drying and subsequent processing of the image.
Flexible printing mainly uses rolls as printing materials. This material not only has the ability to achieve double-sided printing, but also provides diversified technical means such as online photo printing or film coating, metal foiling and mold cutting.
There are many types of materials used to make printing, such as paper, plastic sheets, aluminum plates and other self-adhesive papers.

The production process takes a long time and is also expensive.
The ink carrier in the gravure printing plate exhibits special concave features, which help absorb a large amount of ink elements, thereby forming a rich ink layer structure, vivid color effects and richness of layers.
Gravure printing technology is not limited to printing on traditional paper materials. It is also suitable for printing on film, aluminum foil, transfer paper and other various materials.
4. Discuss equipment costs and maintenance matters

The capital investment of this equipment is quite reasonable and economical, and it is very suitable for medium to large-scale production operations.
Maintenance saves a lot of money and is relatively simple.

Because the cost of the equipment is quite high, this provides excellent conditions for mass production.
The cost of maintenance is often relatively high, so it relies on a specialized technical team to perform related operations and maintenance.
After in-depth analysis, CI flexo printing and rotogravure printing have shown significant differences between them in many areas such as definition, operating mechanism, printing effects and application occasions, plate making techniques, required materials, as well as equipment costs and maintenance. The difference. When deciding which printing technology to choose, a variety of key factors need to be fully and in-depth considered, including the specific needs of the print, the scale of manufacturing and possible future cost estimates.
