In this case, spot color appears to make up for this deficiency. Spot color is directly printed according to the proportion of the chromatogram to allocate the required ink color. The color does not need to be controlled by point density, so the whole color is solid and looks more textured.

專色是金色和銀色，但實(shí)際上潘通光譜中有成千上萬(wàn)種專色。如果所需要的顏色不在色譜上，也可以根據(jù)色彩大師的經(jīng)驗(yàn)來(lái)調(diào)整所需要的顏色，來(lái)找到油墨的比例。濟(jì)南臺(tái)歷掛歷一般在高檔書刊中起點(diǎn)綴作用，但多用于包裝，使印刷色彩更有質(zhì)感，視覺(jué)沖擊力更強(qiáng)，如香煙包裝等。

Spot colors are gold and silver, but there are actually thousands of spot colors in the Pantone spectrum. If the required color is not on the chromatogram, you can also adjust the required color according to the experience of color masters to find the proportion of ink. Jinan desk calendar is generally used in high-end books and periodicals, but it is mostly used for packaging, which makes the printing color more textural and has stronger visual impact, such as cigarette packaging.

臺(tái)歷打印設(shè)計(jì)要考慮到實(shí)際尺寸與日歷寬度長(zhǎng)度的比例;設(shè)應(yīng)考慮實(shí)際尺寸的月歷與長(zhǎng)寬比:有的月歷是方形的，有縱向長(zhǎng)條的，也有橫向長(zhǎng)方形的，設(shè)應(yīng)考慮實(shí)際尺寸與長(zhǎng)寬比的關(guān)系，設(shè)計(jì)后盡量美觀。

The design of desk calendar printing should consider the ratio between the actual size and the calendar width; the design should consider the actual size of the calendar and the length width ratio: some calendars are square, there are longitudinal strips, there are also horizontal rectangular, the design should consider the relationship between the actual size and the length width ratio, and try to be beautiful after design.

影響飛墨的要素

Factors affecting flying ink

(1)油墨黏渡過(guò)大，油墨在墨輥出口處被拉長(zhǎng)，易產(chǎn)生飛墨，同時(shí)還會(huì)構(gòu)成傳墨不勻，使紙張拔毛脫粉，濟(jì)南臺(tái)歷印刷紙張從橡皮布上剝離艱難，易花版、掉版等;黏渡過(guò)小，墨層團(tuán)結(jié)不佳，易產(chǎn)生飛墨，同時(shí)易使油墨乳化，起浮臟、糊版、網(wǎng)點(diǎn)擴(kuò)展，影響印刷產(chǎn)質(zhì)量量。

(1) The ink is too sticky, and the ink is elongated at the outlet of the ink roller, which is easy to produce flying ink. At the same time, it also causes uneven ink transfer, which makes the paper hairy and powdery. It is difficult for Jinan calendar printing paper to peel off from the blanket, and it is easy to print and drop; It is easy to produce flying ink, emulsify the ink, float dirty, paste plate and dot expansion, which affect the printing yield and quality.

(2)墨輥上墨層愈厚，飛墨愈大。打樣在銅版紙上，墨層厚度在1.2μm時(shí)，版上油墨只需抵達(dá)2.8g/m2就行;但用膠版紙印刷，版上油墨少要抵達(dá)4g/m2。遇到紙張性能對(duì)油墨黏附力不好的狀況，易構(gòu)成墨輥堆墨，從而產(chǎn)生飛墨。

(2) The thicker the ink layer on the roller, the larger the flying ink. For proofing on coated paper, when the ink layer thickness is 1.2 μ m, the ink on the plate only needs to reach 2.8g/m2, but for offset paper printing, less ink on the plate needs to reach 4G / m2. When the paper performance is not good for ink adhesion, it is easy to form ink roller pile, resulting in flying ink.

(3) 墨輥外表凹凸不平及外表干結(jié)龜裂時(shí)，局部油墨層加厚，墨霧量增大，易產(chǎn)生飛墨。

(3) When the roller surface is uneven and the surface is dry and cracked, the local ink layer thickens and the amount of ink mist increases, which is easy to produce flying ink.

(4) 印刷速度增加，飛墨增大。

(4) With the increase of printing speed, the flying ink increases.

(5) 空氣相對(duì)濕度小，促進(jìn)飛墨產(chǎn)生;濕度增大時(shí)，電荷減少，飛墨質(zhì)變小。

(5) When the air relative humidity is low, it promotes the production of flying ink; when the air relative humidity increases, the charge decreases and the quality of flying ink decreases.
