Now there are about a dozen brands and various models on the market, and the price ranges from a few thousand to several tens of thousands. How to buy a satisfactory business card is the most concerned issue for users. The user introduces several issues that need to be paid attention to when purchasing a business card machine:
1. Determine the purchase grade according to your own business scale
Commonly used offset business card machines in the market, whether it is a small machine of three or four thousand yuan or a high-end machine of more than 10,000 yuan, the printing principle is actually the same, using the PS version to print using the principle of ink separation, minicomputer and high-end Compared with the speed of adjustment and printing speed, the machine generally does not have much difference in quality when printing ordinary business cards. Therefore, you must consider your own business scale before purchasing, that is to say: if the business card company you operate in small and medium-sized towns or business card companies is small, the daily business volume is not very large (such as the average daily business volume of offset business cards only A few boxes or dozens of boxes), it is best to give priority to the purchase of a small machine (such as Tianjin New Construction ultra-small color offset business card machine), it can fully meet the business needs of the general small and medium business card, do not have to press the funds, in Economically, it is also quite cost-effective. If the business card company you operate is located in a large and medium-sized city and has a large scale, or you have a number of pick-up points in addition to the store, professionally processing a large number of business cards (average dozens of boxes or hundreds of boxes of business cards per day), then you can Consider purchasing a high-speed offset business card machine with high speed and high precision.
2, understand the overall printing speed of the business card machine
High-end machines of more than 10,000 yuan are nominally in the promotion materials and product performance. The printing speed of the business card machine is 25 to 100 sheets per minute, but this is only the motor speed of the business card machine, and does not represent the overall printing speed of the business card machine. Because printing a box of business cards to do pre-press adjustment, color change, ink washing and many other processes, the business card machine's fast adjustment speed, fast ink washing speed is the real key to a good business card machine.
The adjustment speed refers to the time when the PS version is hung on the roller of the offset printing machine, and then the world, the left and right and the oblique are adjusted until the first business card is printed. Most of the offset business card machines are adjusted when the left and right sides are inclined. It is very easy, but it is different when adjusting the world. At present, the general adjustment mechanism of the business card machine on the market adopts the conventional fixed center-to-side worm gear transmission adjustment mode (that is, the heaven and earth adjustment device is on the left front side of the machine). When adjusting the world, first loosen one or two locking screws, then turn the adjusting screw, adjust the approximate position, and then lock the two fixing screws. If the position of the heavens and the earth is not correct, loosen the two locking screws and fine-tune the adjusting screw repeatedly until the world is adjusted to the correct position. Another adjustment method (such as the Southern Color Printing King III) uses an open worm gear transmission adjustment mode (the heaven and earth adjustment device is on the center shaft), and only needs to loosen one locking screw when adjusting the world. Make adjustments and adjust the speed of the user at a glance. The adjustment of the high-end imported business card machine is digitally controlled. There is no mechanical adjustment screw or screw on the outside of the machine. The adjustment is more convenient and quick, but because the price is too high, it is difficult to recover the cost, so there is no market guarantee. Recommended to buy. In addition, when cleaning the ink automatically, some business card machines need to wash the ink for 5 to 10 minutes, and some business card machines only take 1 to 3 minutes, and some machines need to be inked after the ink is not cleaned. Roller removal is wiped one by one with a rag, which wastes a lot of time and indirectly reduces work efficiency, so the user must let the dealer demonstrate the ink washing process when purchasing the machine.
3. Understand the overprinting accuracy and ink quality of business card machines
The overprinting precision of the high-grade offset business card machine has a decisive influence on the printing quality of the business card. When testing the overprinting precision of the business card machine, the first printed business card is usually put back into the machine, without any adjustment. The second printing is carried out, so that the card printing machine with high precision of overprinting does not produce ghost images, and some business card machines with high precision of overprinting still do not produce ghost images after repeated reprinting three times, and the text is not out of shape.
In addition, the world's adjustment device of the business card machine also determines the printing accuracy: if some domestically produced machines adjust the sub-gap between the screw gears, the direct performance is that the adjusting screw is large when the front and rear are screwed, and the adjusting screw is screwed. /3 laps or even half a lap can drive the paper advancement, the adjustment distance is not easy to grasp; there are some business card machine world adjustment device, there is no slot on the locking screw, only the hand can be tightened by hand after adjustment The tool (screwdriver) is locked so that the overprinting accuracy is affected by errors in the world when the machine is running at high speed or in large quantities. In the purchase test, it is best to manually twist the locked adjustment screw to see if it is easy to loose or the neutral is large.
The quality of ink washing will also have a certain impact on the quality of business card printing. Especially when printing high-grade four-color business cards, if the ink is not clean, it will affect the accuracy of the color of the business card. The user can ask the manufacturer to print with black ink first, and then directly print the light ink (such as yellow) after the machine automatically washes the ink, and observe whether the color of the ink printed on the paper is mixed, for the machine without obvious color mixing, at the time of purchase. Priority is given. If the color printed on the paper is black or the color is serious, the quality of the automatic ink washing of the business card machine is not very good.
4. Understand the printing effect of the full version of the business card machine.
Many professionally designed business cards often use full-page anti-white or large-area color blocks to reverse text. Some business card machines have unreasonable design, small printing pressure or poor ink balance. They often appear horizontal light water marks or uneven ink on the business card paper when printing in the full version. Therefore, when purchasing a business card machine, it is best to let the dealer demonstrate the full-scale printing effect on the spot.
Special note: With the popularity of business card machines, it will definitely lead to a reduction in the price of business cards, resulting in fierce competition among business cards. Therefore, when purchasing a business card machine, do not rely solely on the distributor's verbal promotion or the price of the business card machine alone. Once the high-priced business card machine is purchased at a high price, not only is the work efficiency low, the printing quality is poor, and it is difficult to recover the investment in a short time. The high-quality business card machine can not only double the work efficiency, but also enable the operators to remain invincible in the fierce market competition.
