專色是指在打印時(shí)，不是通過(guò)打印C、M、Y、K來(lái)合成這種顏色，而是使用特定的墨水來(lái)打印顏色。專色油墨由印刷廠預(yù)調(diào)或由油墨廠生產(chǎn)。印刷品的每一種專色，在印刷時(shí)都有與之對(duì)應(yīng)的特殊色版。

Spot color refers to that when printing, the color is not synthesized by printing C, m, y and K, but printed with specific ink. Spot color inks are preset by the printing factory or produced by the ink factory. Each spot color of printed matter has a special color plate corresponding to it when printing.

使用專色使顏色更準(zhǔn)確。雖然無(wú)法在電腦上準(zhǔn)確地表示顏色，但可以通過(guò)標(biāo)準(zhǔn)配色系統(tǒng)（如Pantone配色系統(tǒng)）的預(yù)印色樣，在紙張上看到顏色的準(zhǔn)確顏色，從而創(chuàng)建一個(gè)非常詳細(xì)的色板卡。

Use spot color to make the color more accurate. Although the color cannot be accurately represented on the computer, the accurate color of the color can be seen on the paper through the pre printed color sample of the standard color matching system (such as Pantone color matching system), so as to create a very detailed color palette card.

對(duì)于設(shè)計(jì)中設(shè)置的非標(biāo)準(zhǔn)專色，印刷廠未必調(diào)配準(zhǔn)確，屏幕上看不到準(zhǔn)確的顏色，所以如果不是特殊需要，不要輕易使用定義的專色自己。

For the non-standard spot color set in the design, the printing factory may not allocate accurately, and the accurate color cannot be seen on the screen. Therefore, if it is not for special needs, do not easily use the defined spot color.

專色印刷是一種靈活復(fù)雜的彩色印刷工藝，應(yīng)合理合理地使用。在印刷包裝的實(shí)際生產(chǎn)過(guò)程中，有時(shí)會(huì)單獨(dú)使用專色，但在很多情況下，是普通四色中的兩種或三種顏色加上一種或兩種專色組合使用。是否使用專色取決于是否有利于降低廢品率和提高產(chǎn)品質(zhì)量；

Spot color printing is a flexible and complex color printing process, which should be used reasonably. In the actual production process of printing and packaging, spot colors are sometimes used alone, but in many cases, two or three of the ordinary four colors plus one or two spot colors are used in combination. The use of spot color depends on whether it is conducive to reducing the scrap rate and improving the product quality;

是否有利于節(jié)省時(shí)間、縮短工期、提高生產(chǎn)效率；是否有利于降低生產(chǎn)成本，增加企業(yè)收入？這就需要包裝印刷廠家的工藝技術(shù)人員在工藝規(guī)劃中綜合考慮工廠的工藝技術(shù)水平、操作人員的技能以及機(jī)械設(shè)備的使用情況，從而制定出合理的生產(chǎn)工藝。

Whether it is conducive to saving time, shortening construction period and improving production efficiency; Is it conducive to reducing production costs and increasing enterprise income? This requires the process technicians of packaging and printing manufacturers to comprehensively consider the process and technical level of the factory, the skills of operators and the use of mechanical equipment in the process planning, so as to formulate a reasonable production process.

專色印刷制備的油墨是根據(jù)色料減法原理得到的，其顏色透明度低，飽和度高。墨色均勻的專色塊通常印在實(shí)底上，墨量應(yīng)適當(dāng)增加。當(dāng)版面墨層厚度較大時(shí)，墨層厚度變化對(duì)顏色變化的敏感度會(huì)降低，因此更容易獲得墨色均勻、厚實(shí)的印刷效果。

The ink prepared by spot color printing is obtained according to the principle of pigment subtraction. Its color transparency is low and its saturation is high. Spot color blocks with uniform ink color are usually printed on the solid bottom, and the amount of ink should be increased appropriately. When the ink layer thickness of the layout is large, the sensitivity of the ink layer thickness change to the color change will be reduced, so it is easier to obtain the printing effect of uniform and thick ink color.

山東印刷包裝提醒大家，由于目前紙張生產(chǎn)廠家技術(shù)水平參差不齊，生產(chǎn)出來(lái)的同規(guī)格紙張表面顏色或多或少會(huì)出現(xiàn)偏差，或發(fā)藍(lán)或發(fā)黃，這對(duì)包裝印刷來(lái)說(shuō)是個(gè)問(wèn)題制造商。控制產(chǎn)品的顏色會(huì)帶來(lái)麻煩。如果專色塊的不透明度能夠合理合理的使用，上述問(wèn)題就可以很好的解決。

Shandong printing and packaging reminds you that due to the uneven technical level of the current paper manufacturers, the surface color of the paper with the same specification will deviate more or less, or turn blue or yellow, which is a problem for packaging and printing. Controlling the color of the product can cause trouble. If the opacity of spot color blocks can be used reasonably, the above problems can be well solved.
