Why not set the resolution in typesetting and graphics software?
The typesetting graphics software is object-oriented software. The representation of text and graphics is expressed in an algorithmic language. The objects produced are not compatible with the resolution. They are output at the output of the output device at the output. When the device resolution is high, the image output resolution of the created page is high. Therefore, graphics software and typesetting software do not need to set the resolution. The image imported in the typesetting and graphics software will read the dot matrix information of the original image when it is output, which is related to the resolution of the original image.
What kind of digital proofing is the most reliable?
Digital proofing will output proofs directly from the computer's prepressed or designed documents, instead of using traditional proofers to simulate proofing with ink. There are many digital proofing methods. The digital proofing schemes introduced by different manufacturers are different. It can be roughly divided into the following categories: 1 Directly output inkjet proofs: This is the easiest way to print files directly by the printer driver. However, because the idea of the inkjet printer is diffused, the color is bright, and the proof is far from the printing result. 2 The second use color management, and then use the inkjet printer output: the color of this method is close to the printing color, but because there is no RIP interpretation, there is still some gap with the printing, and it is easy to make mistakes. 3 After using RIP to explain, use halftone dots to output halftone dots: this method is the same as RIP and the printing plate, and can find related errors with high accuracy. 4 Use the same RIP as the printing film or printing plate, and use the transfer method to express the dots with the color layer, such as DuPont's proofing method.
What level of high-end flatbed scanners are now developing?
With the advancement of technology, flatbed scanners are getting closer and closer to roller scanners. For example, the screen resolution of the Japanese screen company can reach 5300dpi, which can fully meet the requirements of high-end color printing. In addition to resolution, high-end flatbed scanners now generally have the following features: the scanning area is getting larger and larger, and it can scan A3 or larger originals; the density range is up to 4.0, which is comparable to the roller scanner; the scanning speed is high. It can adapt to mass production; it has artificial intelligence function, which can scan according to the original type; eliminate the moiré technology; screen scanning, adapt to the CTP process; the original is widely adapted: photos, lines, prints, positives, negatives. In addition, some high-end flatbed scanners have XY-scan capability: their CCD can be moved in both X and Y directions, enabling higher optical resolution and ensuring higher image quality anywhere on the original table. Resolution and clarity. Some high-end flatbed scanners also have a Z-direction zoom scanning capability: they can change the focal length of the optical system and simultaneously change the scanning area and optical resolution.
What is the scanner's xy scanning technology?
There are many high-end flatbed scanners that use xy scanning technology. They all have "XY" letters on the scanner name, such as AgfascanXY-15, Ar- tixScan600XY, etc., which means the scanner is in the X, Y direction ( That is, the scanning precision on the horizontal and vertical directions is equal. The accuracy of most flatbed scanners in the horizontal and vertical directions is unequal, thus affecting the accuracy and resolution of image scanning. XY scanning technology delivers the highest resolution scanning quality anywhere in the scanner, making it a technological advancement for non-XY technology scanners.
What is the De Moire feature?
De Moire is a scanning patent technology of Japan Screen Corporation and a software. It can effectively eliminate the moiré that exists in certain types of originals. We all have the experience that when scanning fabrics and speakers, even the positive-color originals will produce object moiré. De Moire can automatically detect potential Moire regions in the image and then eliminate them to produce the desired final result.
What is "CopyDot"? How is it different from traditional analog copy?
"CopyDot" is a copy of a dot, which is different from the "copy" of the traditional analog platemaking process. The “copy” in the traditional analog plate making process refers to the film and the photosensitive material are closely combined, and then vacuumed by a copying machine, and then exposed and copied, and then washed with a developing solution, thereby transferring the graphic from one film to another. The purpose of the above. "CopyDot" uses digital image reproduction technology to scan the text, lines and images of the film through a scanner with "CopyDot" function, so that the film dot becomes the corresponding data, and the information on the film can be integrated into the data. Imposition, grouping throughout the digital workflow. It solves the problem that the four-color film is inaccurate due to long storage time, repeated use or too large film format, and the quality problem caused by film yellowing and scratching can also be scanned by the dot scanner. Repairs are not available in traditional analog copies. The scanner's Copy Dot function was developed to accommodate the needs of direct platemaking and digital printing processes, as digital printing does not require film, but sometimes the film that the customer handed over or the previously saved original was film, and Copy Dot was used. Digitally digitize the dots and directly plate or print them together with other content.
