1, it is best to use the iodine lamp printing machine or vacuum printing machine printing version

Printing high-end business card production, printing machine is very important. Because high-end business cards are mostly made with film film, ordinary UV printers produce gaps between the glass plate and the PS plate due to too much light intensity or insufficient pressure. When fabric films or shallow dot films are used to make fabrics, they can easily cause dots. Lost, affect the printing effect. Therefore, it is best to use high-grade iodine lamp stencils or vacuum stencil printers when drying films, so that the printed version of the PS is clear and uniform. (Retail price of small vacuum printer: RMB 3,000)

2, after adjusting the plate position, be sure to lock the adjustment screw

Because of the high-speed rotation of the business card machine during printing, some business cards that have poor design accuracy will therefore have an error. This kind of error is not very obvious when printing or printing a small number of business cards with a small amount of printing. If the amount of printing is large (dozens of boxes or hundreds of boxes) or when printing high-grade four-color business cards, it will appear. Therefore, when printing a four-color business card, after adjusting the position of the heavens and the earth, it must be locked with a screwdriver, and then one of the left and right stoppers should be locked with a screwdriver (usually the left stopper is locked), only when changing the paper. Loosing the right side gauge can not only ensure that the business card will not be misaligned at the time of printing, but also can avoid the printing error caused by the length of the paper.

3, if there is black overprint, must do to make whitening

When printing a four-color business card, if the business card has a color image or a large area of ​​light-colored blocks as the background and there are black texts in the background, then it is necessary to pay attention to the design, and it is necessary to make dew-white treatment on the layout. Otherwise, the place where there are black characters on the background is printed on the paper is blank, and it is more difficult to overprint the black characters. If you use a business card machine with a low precision, the effect is even worse. The specific way to make up the dew is to select the black text as “overprint black” when the color is selected. (In the Mongolian software, not only can you easily select the black overprint, you can also set the automatic or manual replacement dew)

4. Pay attention to the order of colors printed when printing ink

Most people think that when printing a four-color business card, you can print that color first. In actual fact, the correct order is to print the first red or blue, yellow again, and finally black. Because magenta and magenta are dark in color, after printing on paper, the naked eye can easily distinguish the depth of the color. After overprinting yellow, if the color is not correct, it can be easily distinguished and adjusted in time. On the contrary, if the yellow is printed first, since the yellow is light, the change of the depth of the color after printing on the paper is not easy to find. When the magenta or the product is overprinted, it is not easy to adjust the color once it is found.
