喷墨打印纸的技术的特点

发布人:济南华政印务有限公司 发布时间:2021-11-15

一般来说,喷墨打印介质生产厂商按染料墨和新一代颜料墨打印系统来区分。噴墨纸在使用中有四种不同的涂层,这些涂层或者把色料吸收进去或者使色料只停留在表层。

Generally speaking, manufacturers of inkjet printing media are distinguished by dye ink and new generation pigment ink printing systems. Inkjet paper has four different coatings in use. These coatings either absorb the pigment or keep the pigment only on the surface.
此外根据厂商和生产过程每种涂层技术还有很多区别,以使涂层大优化地配合墨水,打印方式和基材。
In addition, there are many differences in each coating technology according to the manufacturer and production process, so that the coating can greatly optimize the matching of ink, printing mode and substrate.
多孔涂层
Porous coating
这种涂层的纸性价比很好,克重从80g/m2的普通纸到500g/m2(如艺术纸)不等。表面有所谓的快干涂层。这种纸使用硅系涂层,另有添加剂如粘接剂,增白剂。涂层可以按成分,添加剂溶解方式和应用的不同单独来调配. 这样像从暗房出来的纸一样厂商就可以达到较低,中等和较高的分辨率。
The coated paper has good cost performance, and the gram weight ranges from 80g / m2 ordinary paper to 500g / m2 (such as art paper). There is a so-called quick drying coating on the surface. This paper uses silicon coating and additives such as adhesive and brightener. The coating can be prepared separately according to the composition, additives, dissolution methods and applications. In this way, like the paper from the darkroom, the manufacturer can achieve low, medium and high resolution.
对墨滴的大小来说,喷墨材料涂层的溶解方式很关键。墨滴越大,纸张越快达到大的色密度,墨量超出大密度范围时不会产生色彩上的差别,而打印机却大大降低了分辨率,因为这时用较少的墨滴就可以达到理想的效果。过多的墨量使纸张变厚而不能表现不同的色调。这对于哑光的艺术纸是个问题, 因为原则上艺术纸比照片纸的色域窄。从这方面看对于打印纸上的终效果,打印系统的分辨率起不到很重要的作用。起决定作用的是,墨滴在接触纸张表面的时候是否产生大的或小的墨点。所形成的墨点的形状和密度很重要,而这又取决于涂层的成分。
For the size of ink droplets, the dissolution mode of inkjet material coating is very important. The larger the ink drop, the faster the paper reaches a large color density. When the ink amount exceeds the large density range, there will be no color difference, but the printer greatly reduces the resolution, because at this time, the ideal effect can be achieved with fewer ink drops. Too much ink makes the paper thicker and can't show different colors. This is a problem for matte art paper, because in principle, art paper has a narrower color gamut than photo paper. From this point of view, the resolution of the printing system does not play a very important role in the final effect on the printing paper. The decisive factor is whether the ink droplets produce large or small ink spots when they contact the surface of the paper. The shape and density of the ink dots formed are very important, which depends on the composition of the coating.

由于普通喷墨介质在涂层和原纸之间没有屏蔽涂料,墨水可以长驱直入。薄的介质和涂层造成纸张表面波浪起伏,就是所谓的堆墨。墨量大的话堆墨会造成打印头随纸张移动。所以涂层越厚,水分进入基底层越慢,就相应延迟了波纹现象的形成。
Because the common inkjet medium has no shielding coating between the coating and the base paper, the ink can drive straight in. Thin media and coatings cause waves on the paper surface, which is called ink stacking. A large amount of ink will cause the print head to move with the paper. Therefore, the thicker the coating, the slower the water enters the base layer, which delays the formation of ripple phenomenon.
膨润型涂层
Swelling coating
这种涂层可用在带有屏蔽涂料預涂层的纸张,照片纸和各种胶片上。克重从120 g/m2 到300 g/m2 不等。比如Sihl把屏蔽材料作为防水层涂在普通纸上,产生近似于涂塑的效果。但是纸张的防水从来都不是100%的,所以墨量大时仍会形成轻微的波纹。
This coating can be used on paper, photo paper and various films with pre coating of shielding coating. The gram weight ranges from 120 g / m2 to 300 g / m2. For example, Sihl uses the shielding material as a waterproof layer on ordinary paper to produce an effect similar to plastic coating. However, the waterproof of paper is never 100%, so slight ripples will still be formed when the amount of ink is large.
膨润型涂层是一种吸水膨胀的涂层,打印时墨滴使涂层软化,膨胀而进入基材。膨润后涂层需要较长的干燥时间,大多要20分钟左右,这让实际的应用变得复杂化。在干燥过程中,涂层很敏感,不能触碰。
Swelling coating is a kind of water absorbing and expanding coating. During printing, ink droplets soften the coating and expand into the substrate. After swelling, the coating needs a long drying time, mostly about 20 minutes, which complicates the practical application. During the drying process, the coating is very sensitive and cannot be touched.
基于膨润型涂层的这种特性,它只对某些种类的墨水是理想的,因此通用性较窄。例如含高温蒸发液体成分(乙二醇)多的墨水与这种涂层不相匹配,因为这些成分会在表面渗出,产生一种彩色油膜。这些成分蒸发温度在280°C-340°C之间,几个星期之后才能干,或者使用电吹风和烘箱使其加速干燥。
Based on this characteristic of bentonite coating, it is ideal only for some kinds of inks, so its versatility is narrow. For example, ink containing high-temperature evaporated liquid components (ethylene glycol) does not match this coating, because these components will seep out on the surface to produce a color oil film. The evaporation temperature of these components is between 280 ° C and 340 ° C, and they can not dry until a few weeks, or they can be accelerated by using electric hair dryer and oven.
原则上这种涂层目前只适用于水性染料墨,而不能用于颜料墨。
In principle, this coating is only applicable to water-based dye ink, not pigment ink.
高品质的照片纸大多双面淋膜,有好几层基材。淋膜使得纸张在气候变化时不那么敏感,涂布层没有这个作用。
High quality photo paper is mostly coated on both sides with several layers of substrate. The film makes the paper less sensitive to climate change, and the coating layer does not have this effect.
膨润型涂层由于是慢干,在喷墨打印机上使用快速打印模式时也会有问题。相邻的墨滴在静止之前遇上已附着在纸张表面的墨滴而互相融合,这个过程不断重复就造成泪滴现象,出现表面斑驳不匀。
Due to the slow drying of bentonite coating, there will also be problems when using fast printing mode on inkjet printer. The adjacent ink drops meet the ink drops that have been attached to the surface of the paper before they stand still and fuse with each other. The continuous repetition of this process will cause the tear drop phenomenon and uneven surface mottled.
这种涂层最大的优点是, 分子聚合物里的色料相互链接,使得氧化气体如臭氧无法接触到色料,相对于别的技术使用这种技术得到的涂层色彩稳定性要大5000倍。存放在室内环境的打印件可保持多年。
The biggest advantage of this coating is that the pigments in the molecular polymer are linked to each other, so that the oxidizing gas such as ozone cannot contact the pigments. Compared with other technologies, the color stability of the coating obtained by this technology is 5000 times greater. Printed copies stored in an indoor environment can be maintained for many years.
铸涂
Cast coating
铸涂纸一般100 g/m2到240 g/m2,基本上是哑光喷墨纸的进一步加工。再加工的过程是先浇上一层3-5μm厚的微孔面涂,再用一个高光的热辊筒烘干。
Cast coated paper is generally 100 g / m2 to 240 g / m2, which is basically the further processing of matte inkjet paper. The reprocessing process is to pour a layer of 3-5 μ M thick microporous surface coating, and then drying with a high gloss hot roller.
经过再加工的纸张不含屏蔽材料,因此打印中或打印后甚至打印干燥后还会有起伏现象。纸张的结构使生产成本相对较低, 因此可以作为性价比高的高光纸出售。但不能作为高品质的打印介质使用,因为墨水的色料会穿过面涂层固定下来, 由于面涂层不是无色透明的,打印出来的色彩基调就像蒙了一层白纱,而因此在照片还原方面表现不佳。
The reprocessed paper does not contain shielding material, so there will be ups and downs during printing or after printing or even after printing drying. The structure of the paper makes the production cost relatively low, so it can be sold as high gloss paper with high cost performance. However, it cannot be used as a high-quality printing medium because the pigment of the ink will be fixed through the surface coating. Because the surface coating is not colorless and transparent, the printed color tone is like a layer of white yarn, so it performs poorly in photo restoration.
在打印效果方面没有什么限制,但会与某些颜料墨出现不匹配现象。像哑光彩喷纸一样, 由于结构开放,内表面积大,色料易被氧化,稳定性较差。打印件应放置于文件夹内或者玻璃板下保存。
There are no restrictions on the printing effect, but it will not match with some pigment inks. Like dumb gloss spray paper, due to open structure, large internal surface area, pigment is easy to be oxidized and poor stability. The printed copy shall be stored in the folder or under the glass plate.
微孔涂层
microporous coating 
一般170 g/m2到300 g/m2,可与传统银盐照片纸媲美,用颜料墨可产生理想的效果。不同厂家的纸张结构有所不同,一般来说原纸要双面淋膜,表面处理从高光到哑光不等。微孔涂层可以单层也可多层,配方与前面提到的多孔涂层接近,只需加入微小的粒子(微米范围=10ˉ?m)。这种结构使纸张表面能立即干燥,但是像其它涂层一样,也要把纸张放置10分钟以挥发水分。如果过早把打印件夹起来或置于玻璃板下,残留的水分和湿气就会串色而发灰,因为靛青,洋红和黄色混合会产生灰色。 这种现象原则上在所有的噴墨纸表面都会出现。
Generally 170 g / m2 to 300 g / m2, which can be comparable to the traditional silver salt photo paper. Pigment ink can produce ideal results. The paper structure of different manufacturers is different. Generally speaking, the base paper should be coated on both sides, and the surface treatment varies from high gloss to matte. The microporous coating can be single-layer or multi-layer. The formula is close to that of the porous coating mentioned above, and only small particles need to be added (micron range = 10) ˉ? m)。 This structure allows the paper surface to dry immediately, but like other coatings, the paper should be placed for 10 minutes to volatilize water. If the print is clamped up prematurely or placed under the glass plate, the residual moisture and moisture will cross color and turn gray, because the mixture of indigo, magenta and yellow will produce gray. In principle, this phenomenon will appear on the surface of all inkjet paper.
