Intelligent scanner

The scanner is a tool that converts the original information into digital information. Today, the development of scanners is not just a hardware driver and color management program, but a set of automatic recognition of originals, color correction of the original, level correction, easy operation and can be output according to user requirements of the intelligent Scanning software.
In August 2000, the Dazhong Daily Printing Center purchased the PrimeScan 8200 drum scanner from Heidelberg and the EskoScan 2636 large-format scanner from Blu-ray. PrimeScan 8200 is an A2+ format roller scanner equipped with intelligent scanning software LinoColor. Its color management system is fully compatible with ColorSync 2.0. It can not only calibrate the entire system, automatically identify originals, but also perform color and level correction. Connected to the Power Macintoch via the SCSl interface for easy operation. The EskoScan 2636 is a new Copy Dot scanner. Compared with the original Esko Scan series scanners, it has a larger scanning area (26in x 36in). The biggest feature is that the electronic structure has been greatly changed. It was originally scanned. Some functions performed by the instrument hardware are replaced by software. The intelligent software JPS 9.0 runs on a P||500 PC and scans faster.
The following uses the PrimeScan 8200 and EskoScan 2636 as examples. Refer to other models of scanners to talk about the more popular intelligent scanners in the printing industry today.
1. Automatically identify the original is a feature of the intelligent scanner. The ordinary scanner can only scan one type of original at a time. If the type of original is large, it must be divided into several times. This has become quite simple since you have a scanner with automatic document recognition. All kinds of manuscripts are fixed on the scanner at one time. After the pre-scanning positioning, each manuscript is set separately and then scanned. The rest of the work is done by the scanner itself. Sometimes we also encounter the situation where the user requests scanning of a certain original with different accuracy. The scanner that automatically recognizes the original can be completed with only one scan. Both the PrimeScan 8200 and the EskoScan 2636 have the ability to automatically recognize originals.
2. Powerful color and level correction functions are another feature of intelligent scanners. Taking the PrimeScan 8200 as an example, the manuscript is displayed in the preview frame after the OverView, and the operator can use the powerful color and gradation correction tools brought by the LinoColor to adjust the manuscript, and the result of each adjustment of the manuscript can be Preview to preview box. Normal scanners have rough color grading options. Intelligent scanners do not have to be reprocessed in image processing software after scanning the image.
3. Automatic correction function. When the original scanner scans the original, if the original position is reversed and tilted, the best method is to scan the image and rotate the scan result in the image processing software. The intelligent scanner has its own uniqueness when dealing with this situation. The PrimeScan 8200 uses the error correction tool in the LinoColor toolbox. When used, a multi-vertical straight line will appear in the preview box. The big box, as long as make a straight line of the box and a preview of the image of the original image can be parallel.
4. Automatic register function. When the customer provided a color separation film, especially in a newspaper printing factory, there was a scanner with automatic registration function, and many jobs became extremely simple. For example EskoScan 2636, only need to fix the four color chips on two or four film bases (in order to determine the size of the commercial film), then use the digitizer to separate the lower right corner, the upper left corner, and the two registrations of the four color patches. The marks are recorded and scanned one by one, and the scanner can automatically complete the synthesis of the four color patches. After the scan, five files are generated, one is a composite file, and the other is a color separation file. When a version is created, a synthetic file can be inserted at a corresponding position on the layout. When the file is scanned, the distribution software will automatically call the four color separation files. As a result, many previously manually-operated jobs that are time-consuming and influencing the quality of the registration process are performed by highly automated scanners. This increases the efficiency and improves the accuracy of print registration.
5. Film automatic network removal function. In the process of scanning, customers often come to the film. Since these manuscripts are the secondary manuscripts that have been added once to the network, moiré stripes of different degrees will appear if they are not subjected to the descreening process. Therefore, these manuscripts are descreened before the manuscripts are printed. Operation is essential. EskoScan 2636 comes with a network removal software Esko DDS, select the appropriate file, click "OK".
6. Automatic film removal function. After the film sent by the customer is scanned, it must be repaired in the image processing software. For the dirty marks on the blank space, it is still better to handle. For the dirty marks in the graphic part, the processing is very careful and time-consuming. However, the content of the film was added to the Internet once. Therefore, it has a certain frequency, and the dirty marks are added artificially and do not have the network frequency. Can we use this to get dirty? EskoScan 2636 uses this to repair dirt. When repairing dirt, just frame the dirty area, select a suitable radius for repair, and click on “Dirty”. Dirty tracks will be removed easily and quickly.
7. The pre-scanning positioning, scanning and processing of the original document can be performed at the same time, and the work efficiency is greatly improved. Ordinary scanner is usually a machine with a computer, scanner driver software and image processing software installed in the same computer, scanner pre-scan positioning, scanning, adjusting pictures can not be simultaneously, and intelligent scanners such as EskoScan 2636, can be equipped with three PCs (an intelligent software to install the scanner JPS 9.0, one for the network, one with a dirty) and a Mac (for image processing), scanner It can be divided into preparation platform (for pre-scan positioning) and scanning platform. Therefore, while the scanner is scanning, on the one hand, it can prepare for the next batch of live pre-scan positioning. On the other hand, it can make adjustments to the scanned pictures, and it can also perform network removal and dirty operations at the same time, greatly improving Work efficiency.
8. Powerful auxiliary functions. In order to meet the needs of image transmission in a wider range, some scanners also have functions such as e-mailing, faxing, and printing to meet the needs of digitalization and networking.
The above-mentioned smart scanners say that they are intelligent, not because they think like people, but that they are a step beyond traditional scanners, and that they save labor and improve work efficiency. A big leap forward. In the future, scanners from various manufacturers will be better. They may be true intelligent scanners. (From "Printing Technology" 2001 2)
