◆Scope of AppLication◆
YA2 ~ YA4 series are suitable for solid and multi-colors printing to the coated paper and paperboard in big format, gold printing, anti-forgery printing, special printing effects such as frosting printing, ripple printing ,refraction printing and ice-flake printing. Further more, they are suitable for not onlyshort-run printing but also long-run printing.
Being adopted the key technologies and devices with its own independence property right,and successfully adopted the maturely advanced technolegyin the modern sheet-fed offsetpress. YA2 - YA4 series not only has the advanced manufacturing processes, but also strictly been tested in the enterprisestandard The ink layer of offset printing is thin, and easy to cause ink barat the full-page solid printing. But to the gravure printing, the amount of pigment transmitted is 4 times more than that of offset printing and flexo pdnting So, ne matter the whole sheet or whole job, no matter the short-run printing or long-run printing, regardless of texture of theprinting paper, the series can keep the first-class printing quality, and does net cause any ink bar on the printed sheet. In addgion, whether the sheet is dry or wet will net cause change of ink supply, and can directly carry out the post-printing in the delivery.
