行業|話說銅版紙噴墨:從“能不能印”到“印得好”的技術密碼

为此，方正印捷别开设【话说銅版紙喷墨】专栏，带您探寻銅版紙喷墨印刷的世界，看清銅版紙喷墨印刷的真实进度条。
随着銅版紙喷墨技術的不断发展，越来越多的企业开始尝试用喷墨技術印刷銅版紙。然而，从“能不能印”到“印得好”，中间还有很长的路要走。本文将详细探讨銅版紙喷墨技術的核心问题，并提供系统的解决方案。
要实现从“能不能印”到“印得好”的跨越，关键在于突破两大技術难点：其一，是墨斑（噪点）导致的图像细腻度差的问题；其二，70%–80%的銅版紙订单中存在大面积平网或纯色块，会出现白线、拉丝、墨杠、色差及拼接黑线等喷墨特有的技術缺陷。
攻克細膩度難關
銅版紙喷墨的“墨斑”之痛
一、墨斑：細膩度差的根本原因
光铜纸表面有一层致密、光滑的涂层，对于水性颜料墨水，光铜的渗墨性差，墨滴喷射到光铜上后着墨性差，会出现墨滴瞬间移动、两三个墨滴“向一起聚”的现象，即“堆墨”现象。
而一个墨滴即是一个调频网点（喷墨一般都采用调频加网），堆墨就会引起网点分布不均匀甚至两三个网点几乎堆积成一个大网点，形成噪点（日本企业叫噪点，方正叫墨斑）。从而，导致圖片及平网、色块的视觉粗糙、细腻度差、清晰度不够的问题。
墨斑爲何成爲高頻痛點？
墨斑的显现程度与图像精度、阶调密切相关，墨斑常见于精度不够高的圖片，尤以企事业宣传畫冊中的人物照片、産品畫冊中的照片最为严重；而一些极其精美的高精度照片反而不容易出现墨斑（噪点）。同时，不同阶调的平网、圖片墨斑轻重也有差异。
遗憾的是，商务印刷的常规活件多属一般精度文件。因此，墨斑不仅是技術问题，更是实际生产中影响上游客户验收的核心痛点。
细腻度：銅版紙喷墨的“生死线”
毫不夸张地说，光铜纸喷墨的细腻度是决定其市场竞争力的“生死线”。如果墨斑问题得不到较好解决，喷墨印刷的效果将显著劣于碳粉机、Indigo及膠印。从微观角度来看，客户对粗糙质感的敏感度会直接影响订单的验收率，导致验收风险上升；从宏观角度来看，长期未能解决的技術瓶颈可能会动摇市场对喷墨工艺的认可度，进而影响整个行业的信任基础。

"A list of the things you are going to buy," Mary remarked. To regain the highroad we had turned into a northerly fork, and were in as lovely a spot as we had seen all day. Before us and close on our right were the dense woods of magnolia, water-oak, tupelo and a hundred other affluent things that towered and spread or clambered and hung. On the left lay the old field, tawny with bending sedge and teeming with the yellow rays of the sun's last hour. This field we overlooked through a fence-row of persimmon and wild plum. Among these bushes, half fallen into a rain-gully, a catalpa, of belated bloom, was loaded with blossoms and bees, and I was directing Camille's glance to it when the shots came. Another outcry or two followed, and then a weird silence. Ferry led Kendall and me into the woods, the other two remaining. We found rising ground, and had ridden but a few minutes when from its crest we looked upon a startling sight. In front of us was a stretch of specially well farmed land. Our woods swept round it on both sides, crossed a highway, and gradually closed in again so as to terminate the opening about half a mile away. Always the same crops, bottom cause of the war: from us to the road an admirable planting of cotton, and from there to the farther woods as goodly a show of thick corn. The whole acreage swept downward to that terminus, at the same time sinking inward from the two sides. On the highway shone the lighted rear window of a roadside "store," and down the two sides of the whole tract stretched the hundred tent-fires of two brigade camps of the enemy's cavalry. Their new, white canvases were pitched in long, even alleys following the borders of the wood, from which the brush had been cut away far enough for half of them to stand under the trees. The men had quieted down to sleep, but at one tent very near us a group of regimental officers sat in the light of a torch-basket, and by them were planted their colors. A quartet of capital voices were singing, and one who joined the chorus, standing by the flag, absently yet caressingly spread it at such breadth that we easily read on it the name of the command. Let me leave that out. "Quite so. The man was all twisted from his hip, and he had a crooked nose." They were all flying from the plague, which was spreading, and emptying the bazaars and workshops. The Exchange being closed, trade was at a standstill, and the poor creatures who were spared by the pestilence were in danger of dying of hunger. “But she knew them,” objected Dick. “She wouldn’t throw over the wrong ones and she couldn’t get the right ones.” “That’s what we thought.” "Well, if I had sich a name as that I wouldn't expect people to git it right. There's no sense in havin' a Dutch name that makes your tongue crack like a whip. Well, this Mr. McFillemgoody is Si's boss, and he writes a nice letter, and says Si done so well at Chickamaugy that some other boss—a Colonel or Corporal—" "It is not good to be free," he said at last, in a reasonable, weary tone. "In the cold there is a bad thing. In the rain there is a bad thing. To be free is to go to these bad things." "To London!" HoME免费看一级a视频ENTER NUMBET 003ydqzrx.net.cn
