In Europe and the United States, accounting books are printed on business forms. With the further development of computerization of financial services, the printing of books has undergone great changes, especially with the second comprehensive online transition as a turning point. The book printing industry has demanded OMR printing technology and magnetic stripe processing technology.
Book types and specifications
1. Kind
(1) According to the purpose of the account book, there are the following types: 1 Accounts for integrated accounts; 2 Ordinary passbooks; 3 Regular passbooks; 4 Periodic accumulative passbooks;
(2) There are two types in the form of bookkeeping: 1 tight books, which are books that have been used long ago; 2 horizontal books, with the online of bookkeeping, the current model books have become mainstream.
2. Account book specifications
The past online books are only suitable for terminals used by financial institutions. Each terminal manufacturer specifies the printed materials that meet the requirements and the detailed specifications of the printing process to meet the specified accuracy. The specifications and composition of the magnetic book used for the online terminal currently used are as follows.
(1) Cover: 1 It is formed by initializing the cover book and account book paper with the account book; 2 The cover includes the cover and the thickness is 0.3mm; 3 The magnetic seal is applied in the seal.
(2) Inner paper: 1 The inner paper is generally 5 sheets of offset paper with thickness of 01.25mm or 4 sheets of offset paper with thickness of 0.15mm; 2 The inner paper should not be affected by embossing.
Book features
1. Heat resistance: When the temperature is -10°C to 45°C for 39 minutes, and then it is returned to room temperature for 2 small hours, its x direction (printing direction) expansion rate should be less than 0.6%. The directional stretch rate (printing and vertical direction) should be less than 0.3%.
2. Moisture resistance: The humidity is generally between 30% and 85%. When the temperature changes by 40%, the x-direction expansion and contractibility rate is less than 0.6%, and the Y-direction expansion and contraction rate should be less than 3%.
3. Wrinkling of accounts: Under the condition of a temperature of -10°C to 45°C and a humidity of 30% to 85%, the amount of widening due to wrinkling when the books are folded in two should be less than 8mm.
4. Adhesion: When the books are stacked and stored together, there should be no adhesion between the books.
5. Magnetic properties:
(1) Magnetic properties
1 Remanent flux (Ф) = 1.3 × 10-8 ± 0.2Wb; 2 Coercive force (Hc) = 290 ± 20e; 3 angle type ratio is 0.7 or more; 4 thickness is 14 ± 3μm.
(2) Output characteristics
1 Magnetic stripe reading output change is 100V±15%; 2 Magnetic stripe signal to noise ratio should be below 25; 3 Magnetic stripe sticking force is above 600g/12.7mm (measurement method according to JSC2107); 4 Magnetic stripe durability, requirements Can read more than 1000 times, and after writing, there is no abnormal situation of the output voltage; 5 The sticking method of the magnetic stripe can use the thermal type or pressure sensitive type, pay attention to the adhesive cannot overflow.
Book printing materials
When the book printing process is performed, the printed materials used are mainly book cover materials, text sheets, printing inks, and the like. Use materials correctly.
Book cover material
Book cover materials, generally cloth seals and paper seals. The cloth seal is made of interwoven cloth adhesive lining. There are thick and thin cloth patterns, seals are mainly used for magnetic tape bonding type of expansion book. Paper seals are based on synthetic paper and other paper bases. Because the surface is smooth, they are often used for transfer books with magnetic strips. The cloth book book village requires printability, sealability, suitability for tape processing, and suitability for the use of ballpoint pens, and the flexibility should be small.
2. Printing paper
The paper used for the account structure is usually the special paper used in the online billing paper. The opacity of the paper and OMR readability are all important indicators.
3. Printing ink
In order to meet OMR readability requirements, except for the time stamp, all need to be printed with a high reflectance color ink. The printing process requires strict PCS density management.
Bookmaking and Printing
1. Making plate
The production of the book of the book of books is almost the same as that of the production of the ordinary table printing. Recently, on-line terminals use accounts, and because of the inclusion of a time stamp for automatic inter-line settings and a barcode for detecting a page number, it is necessary to make a master with extremely high dimensional accuracy.
2. Printing
Offset printing is the main printing method used in book printing. Fast-printing presses are mainly sheet-fed offset presses with more than two colors. Occasionally, business-type printing presses are used. When printing, it is necessary to ensure accurate overprinting and strict compliance with printing density requirements. For automatic mark-to-line time stamping and high-reflectivity color print density management, an OCR test meter is used. The related printing density is given by each terminal manufacturer as the value of the printed contrast signal. In addition, when printing and printing, it is necessary to use an ink with a good cloth surface adhesion.
Book binding processing
In the production and processing of books, the most important is binding processing. The slimming and binding processing machinery includes the tribute machine, my cutting machine, the right to lock the line, the sticking machine, the compacting machine, the creasing machine, the filleting machine, the magnetic stripe processing machine, the magnetic stripe inspection machine and so on.
Magnetic books
With the on-line deposit business, the magnetization of books has also progressed. Adding a magnetic stripe to the books can reduce the number of terminal operators or even the development of unmanned terminals. The method of processing the magnetic strip mainly adopts a method of heating and bonding the adhesive, or a transfer method of transferring the magnetic stripe by heat transfer and adhesion. At present, the color coating on the magnetic stripe has been developed and put into use. The use of different magnetic stripe processing methods must also use appropriate processing and inspection equipment. Magnetic stripe processing requires superb production technology. For the finished magnetic stripe, the printing factory must prepare the preencoding for magnetic stripe recording in advance.
Looking to the future
With the development of the financial industry, accounting and printing are also actively adopting new processing technologies. The processing of account books also puts new demands on high-precision special printing technologies. Looking into the future, the future technical issues will mainly include the following aspects:
(1) Chinese character processing function for window terminal printers; (2) Adaptation to window terminals such as thermal printers and inkjet printers; (3) High-density recording processing requirements for magnetic stripe; (4) Adaptation to page numbers Increasing demands.
