Know FM (FM) network

This FM is not a radio AM, FM, but the principle is similar. In the past, to make continuous photographs or photocopies, you must first turn into halftone meshes of neatly arranged sizes, which are easy to produce when printing finer patterns. The phenomenon of "mis-networking" or "net-flowering" cannot achieve the desired quality. After the digital equipment was introduced into the prepress operation, there was a new way to generate outlets, namely FM (FM) outlets.

FM (FM) outlets

The principle and characteristics of the FM (FM) network are not intended to be repeated here. But if one day you have to use an FM network to represent your images, how do you do your homework? What are the problems and concerns? Is the current device suitable? Is the current device suitable? I believe this is what everyone is concerned about. Foreign countries have already had quite complete testing and experience in this area, and they have been specifically listed for later reference only for your reference:

FM network benefits

Better resolution & sharpness.

The picture is brighter and fuller, and the effect and quality of the photo have been similar.

There is no moires and rosettes.

There is no problem with the dot angle and the color registration job is more simplified.

Better tone reproduction effect, and the midtones do not cause the problem of concentration jump due to the mesh connection.

Significantly improved laser printer output quality.

Even newspapers or recycled paper can perform good picture quality.

More than four colors of color printing or metal color printing is most suitable for use, because there is no worry about the wrong network.

The performance of the FM outlets at the edge of the trapping text is much better than that of the traditional outlets. Consider replacing the use of special colors to express the text.

The disadvantages of FM outlets

At the initial stage of application, due to the lack of experience in color control, all meshes are required to be proofed on the machine before the color performance can be ascertained. When it is not appropriate, it is necessary to go back to correct the separation curve, which is time-consuming to handle and also increases many costs.

The existing chemical or transfer proofing methods do not fully apply to FM outlets.

Films cannot be chemically trimmed, as thin spots can easily be lost.

Because of the irregular arrangement of the FM screens, there will be a rough feeling in the picture light area.

When outputting at a low resolution, the edges of the text or pattern will appear sharp and jagged. Therefore, it is recommended that the resolution should not be lower than 1000pixel/cm (2540pixel/inch).

When the pictures are aligned, it is more difficult to picture than the traditional dots. A crosshair is needed to supplement the collage.

Shaiban version of the operation, the transparent film base, exposure time, suction standards, light source uniformity are extremely demanding, higher operating costs.

Print for FM performance

Exquisite annual report.

Jewelry catalog.

Medical magazine and pictures.

Photography.

stamp.

Textiles or leather goods with detailed textures must be faithfully represented.

Fine prints, bronze or oil paintings are required.

More than four colors of Hi-Fi Color, there are patterns of worry.

The real benefits of FM sites are only valuable in certain areas of demand. Good results must go through many different tests in order to find out the way and data that are responded to. It is not easy to get. Manufacturers should have the necessary preparation and awareness.

If the factory already has a complete set of color and quality management data (traditional outlets), it should not be used as a formal operation of FM outlets without careful correction and confirmation.

FM (Compatibility to Plate) and computer direct on-machine (Compoter to Press, GTO-DI technology) networks are the best match for network transfer loss.

FM over-net technology, at this stage, should be an additional form of auxiliary representation of traditional networks and high-line-count networks to make up for possible deficiencies of the two, but not to completely replace it, otherwise there will be high costs. Not necessarily popular troubles.

Compared with ordinary coated paper images, the printed products of the FM outlets have almost no visual difference. Whether customers are willing to accept it at a higher cost still has doubts, and manufacturers must understand this.
