In the actual printing process of Jinan printing factory, there are many solutions to the problem of white edge or lace caused by inaccurate overprinting. Color matching, also known as color matching, is to solve the problem of printing alignment between different colors which is not easy to realize in the actual printing production process by using computer software. In the process of printing, there are many kinds of overlapping objects such as text, graphics and images, and there are many processing methods for overprinting.

　　看补漏白是针对两种专色之间的重叠部分，但如果有三种或三种以上的专色相互重叠，则远地点补漏白区域可以通过两种方式进行处理：重叠和分割。重叠时，图像的陷波部分相互重叠，形成一个黑点，主要用于济南印刷厂的包装印刷。分割时，将陷波部分分开，主要用于商业印刷。

　　If there are three or more spot colors that overlap each other, the apogee trapping area can be processed in two ways: overlapping and segmentation. When overlapped, the notch of the image overlaps with each other to form a black spot, which is mainly used for packaging printing in Jinan printing factory. During segmentation, the notch part is separated, which is mainly used for commercial printing.

　　在套色中，黑色是更引人注目的颜色，所以黑色或深色套印比其他浅色要明显得多。在远地点，黑色是单独取出捕捉，这黑色不再是一个纯黑色，而是一个重新定义的黑色，包括黑色和其他深色。

　　Black is the most eye-catching color, so black or dark overprint is much more obvious than other light colors. In apogee, black is taken out separately to capture, which is no longer a pure black, but a redefined black, including black and other dark colors.

　　什么时候颜色被认为是黑色？远地点规定，当软件中暗颜色的光值大于或等于指定的黑光值且密度大于或等于指定的黑光密度值时，颜色被定义为黑色。默认情况下，只有淡入度值为100%且密度大于1.6的颜色才被视为黑色。在捕黑过程中，必须采用软大捕集值。如果黑色或深色是由多次套印形成的，则无需套印。

　　When is the color considered black? Apogee specifies that when the light value of the dark color in the software is greater than or equal to the specified black light value and the density is greater than or equal to the specified black light density value, the color is defined as black. By default, only colors with a fade value of 100% and a density greater than 1.6 are considered black. In the process of catching black, the soft big catch value must be used. If the black or dark color is formed by multiple overprinting, there is no need to overprint.

　　济南印刷公司默认不会对图像进行陷波，但如果图像与背景色重叠，图像会在背景色的相应位置被掏空，并且图像的大小与掏空的大小相同，因此此时需要对图像进行陷波。图像捕获可分为四种情况：、正常、扩散和阻塞。设为“正常”时，图像边缘有许多锯齿；设为“”时，图像与前景颜色相互展开；设为“展开”时，图像展开为背景颜色；设为“收缩”时，背景颜色展开为图像。

　　Jinan printing company will not notch the image by default, but if the image overlaps with the background color, the image will be hollowed out at the corresponding position of the background color, and the size of the image is the same as the hollowed out size, so it is necessary to notch the image at this time. Image capture can be divided into four situations: Center, normal, diffusion and blocking. When it is set to normal, the image edge has many sawtooth; when it is set to center, the image and foreground color expand mutually; when it is set to expand, the image expands to the background color; when it is set to shrink, the background color expands to the image.

　　在重叠对象中，如果前面的对象是发光的单词或渐变条，并且其捕获处理简单地遵循浅色延伸到深色的原则，则会出现如图所示的情况。可以看出，由于黄色的中性灰密度比青色的中性灰密度要亮，所以渐变条前面的黄色印刷厂将扩展到青色。洋红色的中性灰色密度比青色的中性灰色亮度暗，所以渐变条后端的青色会扩展为洋红色。

　　In overlapping objects, if the preceding object is a glowing word or gradient bar, and its capture processing simply follows the principle of light color extending to dark color, the situation as shown in the figure will appear. It can be seen that since the neutral gray density of yellow is brighter than that of cyan, the yellow printing factory in front of the gradient bar will expand to cyan. The neutral gray density of magenta is darker than that of cyan, so the cyan at the back of the gradient bar will expand to magenta.

　　数字马赛克是一项综合性技术，它不仅受印刷前、印刷后和印刷后一系列技术参数的影响，而且与印刷厂的具体生产情况密切相关。数码拼贴是印刷生产过程中的重要工序。它是根据印刷和印后工艺的要求，合理安排纸张，以达到纸张的更有效利用。让我们进一步了解数字马赛克技术如何有效利用纸张，避免不必要的浪费。

　　Digital mosaic is a comprehensive technology, which is not only affected by a series of technical parameters before, after and after printing, but also closely related to the specific production situation of the printing factory. Digital collage is an important process in the printing process. It is based on the requirements of printing and post printing process, reasonable arrangement of paper, in order to achieve the most effective use of paper. Let's learn more about how digital mosaic technology can effectively use paper to avoid unnecessary waste.

　　由于商业轮转印刷与单张印刷在结构、印刷方式、折叠方式等方面存在一定的差异，因此大板上各页元素的布局也与单张印刷有很大的不同。

　　Because there are some differences between commercial rotary printing and sheet printing in structure, printing mode and folding mode, the layout of each page element on the large board is also very different from that of sheet printing.

　　由于滚筒周长和门宽的限制，滚筒的开口尺寸对印刷公司有一定的限制。目前，商用车轮常用的腹板门宽有546mm、578mm、610mm等几种，所用腹板宽度小于或等于门宽。单张纸压力机的开度要灵活得多。它不仅可以选择分纸、四开、八开等，还可以在特殊情况下（即全开纸可以分为两种规格，一大一小）进行开卷。此外，当不同产品使用的纸张相同时，只要在送纸量与更小送纸量之间建立印版，也可以灵活地选择印版。

　　Because of the limitation of roller circumference and door width, the opening size of roller has certain limitation to printing company. At present, the commonly used web width of commercial wheels is 546mm, 578mm, 610mm, etc. the web width used is less than or equal to the door width. The opening of the sheet press is much more flexible. It can not only choose to split paper, four open paper, eight open paper, etc., but also in special circumstances (that is, full open paper can be divided into two specifications, one large and one small). In addition, when different products use the same paper, as long as a printing plate is set up between the maximum paper feed and the minimum paper feed, the printing plate can also be selected flexibly.

　　转印机的自动对位方式是通过定位检测系统扫描印张上的对位标记，得到测量数据，并将测量数据与标准样张的数据进行比较，并利用差值调整相应滚筒的轴向和周向；而单板印刷机则通过前规和侧规完成纸的定位，然后提取样板，然后观察对准标记和手在放大镜下的动态调整辊的轴向和圆周，以确保套印精度。

　　The automatic alignment method of transfer press is to scan the alignment mark on the printing sheet through the positioning detection system, obtain the measurement data, compare the measurement data with the data of the standard sample sheet, and adjust the axial and circumferential direction of the corresponding drum by using the difference value; while the single plate press completes the paper positioning by front and side gauges, then extracts the template, and then observe the alignment mark and hand in the magnifying glass Under the dynamic adjustment of the roller's axis and circumference, to ensure the accuracy of overprinter.
