在印刷實(shí)地時(shí)，除了墨皮之外，墨輥脫落物也容易粘在墨層上面，它在墨層上呈不規(guī)則三角形，中間為黑點(diǎn)，在脫落物四周為白圈，勾勒出脫落物的形狀，影響印刷品的質(zhì)量。為了防止這一現(xiàn)象，濟(jì)南印刷廠提醒您，加強(qiáng)墨輥日常保養(yǎng)和合理使用非常重要，方法如下：

When printing on the spot, in addition to the ink cover, the ink roll shedding material is also easy to stick to the ink layer. It is irregular triangle on the ink layer, with black dots in the middle and white circles around the shedding material, which outlines the shape of the shedding material and affects the quality of the printed product. In order to prevent this phenomenon, Jinan Printing Factory reminds you that it is very important to strengthen the daily maintenance and reasonable use of ink rollers. The methods are as follows:

①墨輥要經(jīng)常保持清潔干凈，一個(gè)產(chǎn)品印完，節(jié)假日，墨輥應(yīng)清理擦洗干凈，不留任何墨污雜物，以免表面結(jié)膜。

① The ink roller should always be kept clean. After a product is printed, the ink roller should be cleaned and scrubbed on holidays, without any ink dirt and sundries, so as to avoid the surface conjunctiva.

②墨輥的老化，主要是來自于光、熱引起的。墨輥不能放在太陽下曬，或者熱氣、暖氣片附近，防止表面老化現(xiàn)象，或者墨輥發(fā)粘軟化。墨輥節(jié)假日不用時(shí)放在墨輥木架上，在干燥、涼爽的地方。

② The aging of ink rollers is mainly caused by light and heat. The ink roller shall not be placed in the sun or near the hot air or radiator to prevent the surface from aging or the ink roller from becoming sticky and soft. The ink roller shall be placed on the ink roller wooden frame in a dry and cool place when not in use on holidays.

③不要和不揮發(fā)性的油類長(zhǎng)時(shí)間接觸。如機(jī)油、調(diào)墨油、黃油等不宜長(zhǎng)時(shí)間與墨輥接觸，否則易出現(xiàn)膠輥表面發(fā)脹變形開裂現(xiàn)象。

③ Do not contact with nonvolatile oil for a long time. Such as engine oil, ink mixing oil, butter, etc., should not be in contact with the ink roller for a long time, or the rubber roller surface is prone to swelling, deformation and cracking.

④墨輥要避免與膠印潤(rùn)濕液的浸蝕造成的爛膠、掉渣現(xiàn)象。膠印潤(rùn)濕液是呈弱酸性物質(zhì)，含有表面活性劑、潤(rùn)濕劑、乳化劑等物質(zhì)，水斗里添加潤(rùn)濕液時(shí)不要放滿，否則溢出灑潑在墨輥上，或者水分過大后，潤(rùn)濕液化學(xué)物質(zhì)對(duì)墨輥進(jìn)行侵蝕。

④ The ink roller shall avoid the phenomenon of glue erosion and slag falling caused by the erosion of offset printing wetting liquid. The offset printing wetting liquid is a weak acid substance, which contains surfactant, wetting agent, emulsifier and other substances. Do not fill the bucket when adding the wetting liquid, otherwise it will spill on the ink roller, or the chemical substances in the wetting liquid will corrode the ink roller after excessive water.

⑤墨輥脫落物的辦法一般采用人工和機(jī)械打磨，去掉結(jié)膜層和爛膠層。但是，注意墨輥的直徑尺寸，不宜打磨過多。若墨輥破損老化厲害，建議是將裂紋老化的膠輥更換，使用新的墨輥，確保印刷產(chǎn)品質(zhì)量。

⑤ Generally, manual and mechanical grinding is used to eliminate the ink roller falling off, to remove the conjunctiva layer and the rotten glue layer. However, pay attention to the diameter and size of the ink roller, and do not polish too much. If the ink roller is seriously damaged and aged, it is recommended to replace the cracked and aged rubber roller and use a new ink roller to ensure the quality of printing products.
