In order to reduce the operating costs, innovate the stability of production, and meet the requirements of customers, Jinan printing factory's fundamental requirements for varnish are to improve the production efficiency, innovate the production environment and meet the environmental requirements of customers while producing high-quality products.

1)提高光油對高速印刷的順應(yīng)性

1) Improving the compliance of varnish to high speed printing

現(xiàn)在，國產(chǎn)凹印機(jī)的速度通常在150米/分上下，印刷機(jī)速度的提高會低沉印刷廠的營運(yùn)成本，提高效益。因此印刷廠商渴望能順應(yīng)更高印刷速度的塑料凹印光油能早日面市。

At present, the speed of domestic gravure press is usually about 150 m / min. the increase of printing press speed will lower the operating cost of printing plant and improve efficiency. Therefore, printing manufacturers are eager to adapt to the higher printing speed of plastic gravure varnish to be on the market as soon as possible.

2)提高光油著色性

2) Improve the colorability of varnish

所采訪的幾家山東印刷廠都渴望光油生產(chǎn)廠提高光油的著色性，渴望用定量的光油印出更多的活件或定量的活件用少量的光油，以淘汰印刷成本。然而，光油的用量與光油的著色性密切干系。在墨量肯定的環(huán)境下，光油著色性越高，所印活件越多，利潤越大。

Several Shandong printing factories interviewed are eager to improve the colorability of varnish. They are eager to use quantitative varnish to print more live parts or the minimum amount of varnish to eliminate the printing cost. However, the amount of varnish is closely related to the colorability of varnish. In a positive ink environment, the higher the gloss colorability, the more live parts printed, the greater the profit.

3)淘汰助劑的應(yīng)用或應(yīng)用配套助劑

3) Elimination of the application of additives or application of supporting additives

一方面，濟(jì)南印刷廠都渴望所用光油在印刷時可以直接應(yīng)用，不須要添加或很少添加助劑，只須要以溶劑來調(diào)治光油的黏度。因?yàn)樘砑又鷦岣哂∷⒊杀?，增長印刷前的準(zhǔn)備時間，浪費(fèi)人力，還會影響墨性的穩(wěn)固，還會給印刷廠印后加工帶來麻煩。

On the one hand, Jinan printing factory is eager to use varnish directly in printing. It does not need to add or rarely add additives. It only needs to use solvent to adjust the viscosity of varnish. Because the addition of additives will increase the printing cost, increase the preparation time before printing, waste manpower, affect the stability of ink, and bring trouble to the printing factory's post press processing.

另一方面，要緊急劑有肯定的針對性，助劑要與光油配套、結(jié)果明顯且應(yīng)用方便。如黃山新力光油化工廠針對黃山永新股份公司印刷產(chǎn)品的特點(diǎn)配制了相應(yīng)的助劑，此中B-0020、B0142號助劑可有效辦理高速印刷中的刀絲污版妨礙，加入B0142號助劑可提高光油的抗靜電性，同時還不影響里印光油的復(fù)合強(qiáng)度。

On the other hand, the emergency agent must have definite pertinence, the auxiliary agent should be matched with varnish, the result is obvious and the application is convenient. For example, Huangshan Xinli varnish chemical plant has formulated corresponding auxiliaries according to the characteristics of Huangshan Yongxin Co., Ltd. printing products. Among them, b-0020 and b0142 auxiliaries can effectively deal with the interference of knife wire dirty plate in high-speed printing. Adding b0142 auxiliaries can improve the antistatic property of varnish without affecting the composite strength of lining varnish.

濟(jì)南印刷廠中，還存在用過的光油須要短時間存儲的問題，現(xiàn)在許多沒有用完的但已加入助劑的光油根本上不能連續(xù)應(yīng)用，造成了浪費(fèi)。因此，印刷廠渴望應(yīng)用后的光油，儲存1～2個月后經(jīng)大抵處理懲罰處罰還能連續(xù)應(yīng)用，以淘汰光油的浪費(fèi)，節(jié)省成本，這就要求光油生產(chǎn)商辦理光油在調(diào)配后不能連續(xù)應(yīng)用的問題。

In Jinan printing factory, there is still the problem that the used varnish needs to be stored for a short time. Now many unused varnish which has been added with additives can not be used continuously, resulting in waste. Therefore, the printing factory is eager to apply the varnish after storage for 1-2 months, and it can be continuously applied after most of treatment and punishment, so as to eliminate the waste of varnish and save cost. This requires the varnish manufacturer to deal with the problem that the varnish can not be continuously applied after blending.
