Several problems needing attention when printing high-end four-color business cards

1. It is best to use iodine home lamp printer or vacuum printer for printing

printing high-end business cards, and the printer is very important. Because most of the high-end business cards are made with film, the ordinary UV printer will increase the angle between the vertical line of the toothed bar and the push rod if the light intensity is too high or the dynamometer device tilts to the right, and the pressure is not enough, resulting in a gap between the glass plate and the PS plate. When drying the film that is very difficult to decompose in the soil or the film that is shallow, it is very easy to cause point loss and affect the printing effect. Therefore, it is best to use high-end iodine lamp printer or vacuum printer when drying film, so that the PS version of the text is clear and even. (retail price of small vacuum printer: D - the arithmetic mean value of the two diagonal lines of the indentation is about 3000 yuan)

2. After adjusting the position of the printing plate, be sure to lock the adjusting screw

due to the high-speed rotation of the business card machine during printing, some business card opportunities with low design accuracy will cause errors. This error is not very obvious when printing a small amount of business cards or printing simple chromatic business cards. If the printing volume is large (dozens or hundreds of boxes) or printing high-end four-color business cards, it will appear. Therefore, when printing four-color business cards, after adjusting the position of the world, be sure to lock it with a screwdriver, then lock one of the left and right stop gauges with a screwdriver (usually lock the left stop gauge), and only loosen the right stop gauge when changing paper. This can not only ensure that there will be no deviation between the left and right sides of the business card during printing, but also avoid printing errors caused by uneven paper length

3. If there is black overprint, be sure to do the whitening treatment

when printing four-color business cards, if there are color pictures or large areas of light colored blocks as the background, and there are black words on the background, you should pay attention to the design, and be sure to do the whitening treatment on the layout. Otherwise, where there are black words on the background, it is blank on the paper, and then it is more difficult to overprint black words on it. If you use a business card machine with low accuracy, the effect will be even worse. The specific way to fill the exposed white is to select the black text as "overprint black" when selecting the color. (in Montaigne software, it is not only convenient to choose black overprint, but also can set automatic or residents almost do not feel manual exposure)

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

generally speaking, when printing four-color business cards, it is OK to print that color first. In fact, the correct order is to print magenta or orchid first, then yellow, and finally black. Because magenta and magenta are darker in color, it is easy for the naked eye to distinguish the depth of their color after printing on paper. After overprinting yellow, it is also easy to distinguish and adjust in time if the color is incorrect. On the contrary, if you print yellow first, because the yellow is lighter, it is not easy to find the change in color after printing on the paper. When you overprint magenta or magenta, it is not easy to adjust the color once it is found to be incorrect

3. If there is black overprint, be sure to do the whitening treatment

when printing four-color business cards, if there are color pictures or large areas of light colored blocks as the background, and there are black words on the background, you should pay attention to the design, and be sure to do the whitening treatment on the layout. Otherwise, where there are black words on the background, it is blank on the paper, and then it is more difficult to overprint black words on it. If you use a business card machine with low accuracy, the effect will be even worse. The specific way to fill the exposed white is to select the black text as "overprint black" when selecting the color. (in Montaigne software, it is not only convenient to choose black overprint, but also can set automatic or manual whitening)
