Format and quality are the first issues to consider. That is, first determine whether the output size and film quality of the selected machine meet their own needs. In addition to the size of the image, accuracy and repeatability should also be considered. After screening, uniform rose-shaped dot structures should be generated, and moiré patterns cannot be generated. These dot structures will deliver fine image details and a wide range of gradation to produce high-quality images.
A high-performance photo-setter should be able to output high-quality film at a lower resolution, so that the imagesetter can operate at high speed to achieve maximum throughput. If special requirements, such as flexography or screen printing, are required, the standard screen angle needs to be changed by 7.5° to meet these needs. Imagesetter linearization is also very important - it allows the operator to easily control the density and linearity of the output film - so that the dot density output to the film is the ideal density.
The productivity of an image-setter is determined by a series of factors. When considering a decision, the highest load should be considered, not just based on general needs. Only at full load, the actual imaging speed of the imagesetter and the balance between speed and system performance are the most important.
The reliability of the system must be transmitted in a proven and validated technology to ensure consistent output for every production. Remote diagnosis minimizes the downtime caused by a fault and accelerates the necessary processes accordingly. Easy-to-use features should include an intuitive interface that allows for flexible operation, which greatly increases employee productivity.
Flexibility and extensibility refer to the flexible and open device structure used. This structure depends on industry standards rather than the unique technology used by the device. Software RIP based on the True Adobe ® Postsuipt ® 3 industry standard will make your investment worthwhile - because it only needs to change the existing computer into a new model to upgrade RIP to meet high performance equipment Needs.
If you do not combine the actual, then the parameter indicators on the specification is just a bunch of meaningless numbers. Therefore, considering the parameters of the imagesetter, it must be combined with specific quality standards and deadlines. Only in this way can the corresponding parameters be meaningful.
For example, some imagesetters claim to run fast, but in addition to considering the basic imaging speed of the imagesetter, the uploading and downloading time of the film is very long, which will inevitably affect the overall operating speed, resulting in a decrease in production volume.
Another example is reproducibility is also an important indicator, but it does not make sense to consider the indicator from a detail, because environmental factors such as temperature and humidity will have a great impact on output quality.
Also don't think big is good. A large format camera is not a good machine. You should choose a system that fits your company's business size.
In short, the most prudent approach is to use actual jobs to perform tests on a series of machines that are to be purchased. Only then can we truly see how the jobs are produced. Therefore, buyers and sellers can reach a certain degree of consensus.
The choice of the phototype system is very important. There are several factors to consider when choosing a new system.
