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.

　　看補(bǔ)漏白是針對(duì)兩種專色之間的重疊部分，但如果有三種或三種以上的專色相互重疊，則遠(yuǎn)地點(diǎn)補(bǔ)漏白區(qū)域可以通過兩種方式進(jìn)行處理：重疊和分割。重疊時(shí)，圖像的陷波部分相互重疊，形成一個(gè)黑點(diǎn)，主要用于濟(jì)南印刷廠的包裝印刷。分割時(shí)，將陷波部分分開，主要用于商業(yè)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顏色，所以黑色或深色套印比其他淺色要明顯得多。在遠(yuǎn)地點(diǎn)，黑色是單獨(dú)取出捕捉，這黑色不再是一個(gè)純黑色，而是一個(gè)重新定義的黑色，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.

　　什么時(shí)候顏色被認(rèn)為是黑色？遠(yuǎn)地點(diǎn)規(guī)定，當(dāng)軟件中暗顏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時(shí)，顏色被定義為黑色。默認(rèn)情況下，只有淡入度值為100%且密度大于1.6的顏色才被視為黑色。在捕黑過程中，必須采用軟大捕集值。如果黑色或深色是由多次套印形成的，則無需套印。

　　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.

　　濟(jì)南印刷公司默認(rèn)不會(huì)對(duì)圖像進(jìn)行陷波，但如果圖像與背景色重疊，圖像會(huì)在背景色的相應(yīng)位置被掏空，并且圖像的大小與掏空的大小相同，因此此時(shí)需要對(duì)圖像進(jìn)行陷波。圖像捕獲可分為四種情況：、正常、擴(kuò)散和阻塞。設(shè)為“正常”時(shí)，圖像邊緣有許多鋸齒；設(shè)為“”時(shí)，圖像與前景顏色相互展開；設(shè)為“展開”時(shí)，圖像展開為背景顏色；設(shè)為“收縮”時(shí)，背景顏色展開為圖像。

　　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.

　　在重疊對(duì)象中，如果前面的對(duì)象是發(fā)光的單詞或漸變條，并且其捕獲處理簡(jiǎn)單地遵循淺色延伸到深色的原則，則會(huì)出現(xiàn)如圖所示的情況?？梢钥闯?，由于黃色的中性灰密度比青色的中性灰密度要亮，所以漸變條前面的黃色印刷廠將擴(kuò)展到青色。洋紅色的中性灰色密度比青色的中性灰色亮度暗，所以漸變條后端的青色會(huì)擴(kuò)展為洋紅色。

　　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.

　　數(shù)字馬賽克是一項(xiàng)綜合性技術(shù)，它不僅受印刷前、印刷后和印刷后一系列技術(shù)參數(shù)的影響，而且與印刷廠的具體生產(chǎn)情況密切相關(guān)。數(shù)碼拼貼是印刷生產(chǎn)過程中的重要工序。它是根據(jù)印刷和印后工藝的要求，合理安排紙張，以達(dá)到紙張的更有效利用。讓我們進(jìn)一步了解數(shù)字馬賽克技術(shù)如何有效利用紙張，避免不必要的浪費(fèi)。

　　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.

　　由于商業(yè)輪轉(zhuǎn)印刷與單張印刷在結(jié)構(gòu)、印刷方式、折疊方式等方面存在一定的差異，因此大板上各頁(yè)元素的布局也與單張印刷有很大的不同。

　　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.

　　由于滾筒周長(zhǎng)和門寬的限制，滾筒的開口尺寸對(duì)印刷公司有一定的限制。目前，商用車輪常用的腹板門寬有546mm、578mm、610mm等幾種，所用腹板寬度小于或等于門寬。單張紙壓力機(jī)的開度要靈活得多。它不僅可以選擇分紙、四開、八開等，還可以在特殊情況下（即全開紙可以分為兩種規(guī)格，一大一?。┻M(jìn)行開卷。此外，當(dāng)不同產(chǎn)品使用的紙張相同時(shí)，只要在送紙量與更小送紙量之間建立印版，也可以靈活地選擇印版。

　　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.

　　轉(zhuǎn)印機(jī)的自動(dòng)對(duì)位方式是通過定位檢測(cè)系統(tǒng)掃描印張上的對(duì)位標(biāo)記，得到測(cè)量數(shù)據(jù)，并將測(cè)量數(shù)據(jù)與標(biāo)準(zhǔn)樣張的數(shù)據(jù)進(jìn)行比較，并利用差值調(diào)整相應(yīng)滾筒的軸向和周向；而單板印刷機(jī)則通過前規(guī)和側(cè)規(guī)完成紙的定位，然后提取樣板，然后觀察對(duì)準(zhǔn)標(biāo)記和手在放大鏡下的動(dòng)態(tài)調(diào)整輥的軸向和圓周，以確保套印精度。

　　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.
