Although with the development of electronic technology, "paperless office" is becoming a trend, but in daily work, most enterprises and institutions still have to use a lot of printed materials. Such as documents and notices in party and government organs, test papers in schools, publicity materials in commercial units, quotations, etc. This type of printed matter is often dominated by black-and-white manuscripts, and the quantity requirement is relatively large, and the accuracy requirement can be relatively low. Take the school test paper as an example. Originally, the method of oilmark was used. Although it is now possible to use a pin printer to print wax paper (finally do n’t engrave with a stylus and steel plate), the method of oilmark is also too old. Speed Slow and poor printing quality, the shortcomings can be said to be a lot.
Some people say, can't we use a copier or a printer? Yes, the printing quality of these two devices is very good, but the first use cost is high, the second speed is slow, and the number of prints exceeds 50 copies, it is obviously very inappropriate. In fact, there is a device that is aimed at the current situation and the user group required by this application. This is the fast printing machine.
The speed printing machine works by digital scanning and thermal plate-making imaging. The printing quality is clear. The printing speed of mainstream models can reach more than 100 sheets per minute. At the same time, it also has a variety of functions such as zoom printing, splicing printing, automatic paper separation control, etc. Most models can also support the function of direct output of computer printing. So what are the main technical indicators of the fast printing machine, and what problems should be paid attention to when buying?
One. Cognition of main technical indicators
1. Printing format
Like the printer, the printing format is also the first factor to be considered when purchasing a printing machine. If other technologies are inferior, you may be able to reluctantly, but if the size of the printing machine is too small, there is no way. You cannot ask the B4 format printing machine to print A3 for you. Large format documents come.
The printing format of the printing machine is divided into two types: original supporting format, paper output format, and printing output format. The original support format refers to the largest scan format that can be used on the desktop of the printer. The paper output format refers to the maximum output paper that can be used by the printer; the print output format refers to the maximum size of the document that the printer can output. Knowing that no printed matter can print a full sheet of paper, some margins must be left (I think all users who have used Word know this concept very well).
At present, the input format of the mainstream fast printing machine is basically B4 ~ A3 format, and the output format is basically A3 format.
2. Paper quality
Due to the large number of printing on the printing machine, whether it can support more economical paper is directly related to the cost of use. A good printing machine should be compatible with a variety of quality paper, so that it can meet the needs of different users and different applications!
3. Printing speed
Compared with copiers, in addition to low cost, one of the biggest advantages of the speed printer is its printing speed. At present, most of the speed printing machines can reach the printing speed of more than 100 sheets per minute, and there are multiple speeds for users to choose.
4. Printing resolution
The definition of printing is related to the quality of printing. Like printers, it is also marked with dpi, but the accuracy index does not need to be as high as that of printers. Generally, 300 to 400dpi is enough!
5. Supported zoom ratios
This index is the same as that of a copier, it can enlarge and reduce the original manuscript for printing. There is no doubt that the larger the zoom ratio range, the better. However, it should be noted that some products are scaled stepwise, that is to say, it specifies several fixed ratios, and some products are infinitely zoomed. The zoom ratio can be defined by the user and can be accurate to 2 to 3 decimal places. In terms of function, the latter is of course much stronger than the former.
two. Shop for actual combat
1. Focus on key technical indicators
There are many technical indicators of the printing machine, but the key technical indicators that users should pay attention to first when purchasing. Because they determine the basic performance of the product. Especially for the quality of the paper used, for users who have a very high demand for printing and do not have high requirements for paper (such as schools used to print test papers), products that can support more economical paper can allow users Greatly reduce the cost of use.
2. Choose the functionality of the product according to your actual needs
In addition to the differences in basic performance indicators, the printing machine also has many special functions. The functions attached to different products are different, and the differences and the number of functions also directly affect the price of the product, and the difference is relatively large . Therefore, users should choose according to their actual application needs, carefully consider which functions are needed, which functions are not needed, and which functions can be replaced by other devices. That is to avoid the waste of functions, but also to avoid the situation that the required functions are not selected.
3. After-sales service is an important factor in product purchase.
The speed of the printing machine is relatively large, so it is very inconvenient to send the faulty repair, and the on-site repair of the manufacturer is very necessary. At the same time, the rapid printing machine also needs to be regularly maintained and maintained, these are part of the after-sales service. Users must consider when buying, do not make small and cheap to cause big trouble to themselves.
