常用的包装材料性能差异的影响因素.doc

常用的包装材料性能差异的影响因素灰底白板纸和白卡纸是两种常用的包装材料。白板纸是由面浆与各层底浆抄制而成的。其结构主要分为底层、芯层、衬层、面层和涂层等部分。灰底白板纸底面颜色为灰色，由废旧报纸经脱墨而成，所以底层的成分很杂；表面为白色，是一层由高岭土粉、黏合剂等化工原料混合而成的薄涂料面。表层(涂布面)白度较高，油墨吸收性、平滑度和印刷光泽度都很好，纸板本身又具有很好的挺度和耐折度，既能直接用来印刷，又能满足包装的要求。灰底白板纸表面经涂布处理后，表面性能有了很大的提高，既能够满足高质量的彩色印刷要求，又是中高档商品包装盒的优质材料。白卡纸是一种较厚实坚挺的白色卡纸，采用100%漂白硫酸盐木浆为原料，经过游离状打浆，较高程度地施胶(施胶度为1015arm)，加入滑石粉、硫酸钡等白色填料，在长网造纸机上抄造，并经压光或压纹处理而制成。白卡纸一般为单面涂布，市场上主要分为sbs和fbb两种，前者以漂白化学浆为原料，两层结构，特点是白度较高，但同等定量纸板的挺度和厚度较差；后者以漂白化学浆作为纸板的表层和底层，而以机械浆为原料构成中间层，形成三层结构的纸板，其特点是在同等定量的条件下，厚度高，硬度好，从而带来良好的模切效果和折痕效果。WwW.11665.coMGrey, white paper and white cardboard is two kinds of commonly used packaging materials. Whiteboard paper is made from MianJiang and each layer bottom slurry as copy. Its structure is mainly divided into the bottom layer, core layer, lining, coating and surface parts. Manila board bottom color to grey, composed of waste newspapers after deinking, so at the bottom of the composition is very complex; Surface is white, it is a layer of kaolin powder, binder and other chemical raw materials, mixture of thin coating surface. Surface (coated surface) high whiteness, printing ink absorbency, smoothness and gloss are good, stiffness of the paper itself also has the very good and folding, can use to print directly, and can satisfy the requirement of packaging. Manila board surface after coating treatment, surface performance has greatly improved, both can satisfy the requirement of the high quality color printing, packaging of high quality material is high-grade goods. White cardboard is a relatively thick solid white paperboard, using 100% bleached sulphate wood pulp as raw material, after beating YouLiZhuang, higher degree to glue (glue degree is 1.0 1.5 arm), join the talcum powder, barium sulfate, such as white packing, in the long nets manufacture paper with pulp on paper machine, and the pressure or embossing processing, made of a light. General for single-side coated white cardboard, mainly on the market is divided into SBS and FBB two kinds, the former to the bleached chemical pulp as raw material, two layer structure, characterized by white degree is higher, but the same quantitative stiffness and thickness of the cardboard is poorer; For bleached chemical pulp as a surface and the bottom board, and using mechanical pulp as raw materials form the middle tier, cardboard form three layer structure, its characteristic is under the condition of same quantitative, thickness, high hardness, resulting in good die cutting effect and the crease effect.

However, two kinds of paper on the surface performance difference is how much? And the differences of two kinds of paper printing order tone reproduction is influential effect, influence have how old? In this paper, the properties of these two kinds of wrapping paper and order the reproducibility of experimental contrast research, comparative analysis of the performance of the q of the differences and their respective order tone reproduction performance, for the performance of the quantitative analysis of these two kinds of paper, better use of these two kinds of paper to provide some useful reference data. 1实验部分Part 1 experimental 基于这两种包装用纸在表面性能方面存在的差异，首先通过实验测定两种纸张各纸样的基本表面性能；然后依据各纸样的基本表面性能，选用一定的印刷条件，在igt印刷适性仪上印刷打样，找到各纸样的最佳墨层厚度，并在各自最佳墨层厚度下印刷打样；最后，测试各纸样的网点面积率、实地密度值等数据，泰安锅炉对样张进行分析，对比研究这两种包装纸的差异及其对印刷品阶调再现性能的影响。Based on these two kinds of packing paper on the surface performance differences, first of all, through the experimental determination of two kinds of paper pattern of the surface of the basic performance; Then according to the pattern of the surface of the basic performance, choose certain printing conditions, printing proofing on igt printing eligibility instrument, find the best ink film thickness of each pattern, and under the respective optimum ink film thickness printing proofing; Finally, test the dot area rate of each pattern, field density values such as data, analyze the tear sheet, comparative study the differences between these two kinds of wrapping paper to print order tone reproduction performance impact. 实验材料：长兴白板纸(250gm。)、华明白板纸(250gm。)、华丰白板纸(250gm。)、鸿泽白板纸(250gm)、凡南白板纸(250gm。)、亚太白卡纸(250gm)、太阳白卡纸(250gm。)、荷兰白卡纸(250gm)；采用的油墨是天津东洋油墨有限公司的胶印亮光快干型油墨(黄、品、青)。Experiment materials: changxing whiteboard paper (250 g/m). , huaming whiteboard paper (250 g/m). , huafeng whiteboard paper (250 g/m). , hong ze whiteboard paper (250 g/m), every south whiteboard paper (250 g/m). , the white paper (250 g/m), the sun, white cardboard (250 g/m). , the Netherlands, white cardboard (250 g/m); Used in printing ink is tianjin toyo ink co., LTD., the offset of the light quick-drying type printing ink (yellow, taste, and green). 11纸张表面性能的测试1.1 the paper surface properties of the test 实验仪器：wsb一白度计；ugv一50型variabieglossmeter变角光泽仪；ym一20油墨吸收性测定仪；modelm590pakerprintsurf表面粗糙度测试仪。实验环境：温度21，相对湿度4951。通过实验，8种纸样的各项性能数据见表1。Experimental apparatus: station WSB a whiteness meter 2; Ugv variabieglossmeter a 50 type variable Angle gloss meter; Ym a 20 ink absorption apparatus; Modelm590pakerprint - surf surface roughness tester. Experimental environment: temperature of 21 , relative humidity 49 to 51. Through the experiment, eight kinds of pattern of each performance data are shown in table 1. 12确定最佳印刷墨层厚度及印刷打样1.2 to determine the best printing ink layer thickness and the printing proofing 实验仪器、印刷条件、实验环境：igt印刷适性仪(aic25型)，65lear网线辊，xrite528密度计；压力650n，印刷速度02ms；温度2l25，相对湿度4555。通过大量印刷打样及测试，先找出各纸样的最佳墨层厚度(表2所示)，Experimental apparatus, printing conditions, experimental environment: igt printing eligibility instrument (aic2, 5), 65 l/ear network cable roller, x - rite528 densitometer; 650 n pressure, printing speed 0.2 m/s; Temperature 2 l 25 , relative humidity of 45 55. Through a lot of printing proofing and testing, the pattern to find out the optimum ink film thickness (shown in table 2), 再在aic25型igt印刷适性仪上，按照每种纸张的最佳墨层厚度，以上述印刷条件，用同样的油墨分别打出8种纸样的黄、品、青3种单色的网线样张，经对各样张不同网点面积率的网线块及实地色块测量，得出8种纸样黄、品、青3个单色的网点增大值曲线、印刷特性曲线及阶调密度反差曲线。Again in igt printing eligibility aic2, 5 type instrument, according to the optimum ink film thickness of each paper and printed in the above conditions, using the same ink, respectively, with 8 kinds of pattern of yellow, taste, and green three monochrome network cable sample, after the sample different dot area rate of the network cable and field color piece measurement, concluded eight pattern yellow, taste, and green three monochrome network increases value curve, the printing and order adjustable density contrast curve characteristic curves. 2灰底白板纸和白卡纸阶调再现性的对比分析2 grey board paper and white cardboard reproducibility of contrastive analysis 21网点增大值对比分析以品红墨各纸样的网点增大比较图(图1所示)2.1 points increase value contrastive analysis the magenta ink increase the pattern of the outlets comparison chart (shown in figure 1) 为例分析，可以看出，灰底白板纸样条的网点增大情况要比白卡纸的大一些。在影响印刷品网点增大的诸因素中，就纸张而言，纸张的吸收性和粗糙度两个参数对阶调的再现有较大的影响。这两个参数往往与印刷压力密切相关。而在本研究中，采用的印刷压力为一个确定的值，这样，纸张的吸收性和粗糙度的差异就体现出了其对阶调的再现的影响。As an example analysis, it can be seen that grey board paper pattern of the network increase situation it is bigger than the white cardboard. The factors influence the print outlets in increase, in terms of paper, paper absorbency and roughness of the two parameters on the order of representation has a great influence. These two parameters are often closely related to the printing pressure. In this study, using the printing pressure to a certain value, thus, the absorbent paper reflects and roughness of the differences in their effect on the order of representation. 而从前面的纸张表面性能的测试数据来看，灰底白板纸与白卡纸这两类纸，在吸收性、粗糙度上，还是存在着较为明显的差异。白卡纸相对于灰底白板纸，它的吸收性较高，粗糙度较低(荷兰白卡纸是进口卡纸，由于制造工艺不同等原因而属例外)。纸张较高的吸收性可能会导致网点更易于增大，而较低的粗糙度会使纸张在印刷压力的作用下表面变形较少，而且所需墨膜较薄，从而比较有利于减少网点的增大。所以，基本上可以认为灰底白板纸在阶调再现性方面相对于白卡纸较差。And from the paper surface properties of the test data, grey, white paper and white cardboard paper, and the two on the absorbency, roughness, or there are comparatively obvious differences. White cardboard relative to Manila board, its absorption is higher, low roughness (white cardboard is in the Netherlands imported paperboard, due to reasons such as manufacturing process different exception). Paper high absorbent increases could lead to network more easily, and lower roughness can make paper in printing pressure under the action of surface deformation is less, and the ink film is thinner, which is beneficial to reduce the increase of network. So, basically can think Manila board in order the reproducibility relative to the poor white cardboard. 22印刷特性曲线对比分析以品红墨各纸样的印刷特性曲线图(图2)2.2 printing characteristic curve analysis of the magenta ink printing features of each pattern graph (figure 2) 例分析，可以看出，白卡纸的印刷特性曲线基本上都处在灰底白板纸的下方，说明白卡纸的阶调密度误差相对较小。可见，白卡纸的阶调再现性能要好于灰底白板纸的阶调再现性能。Case analysis, it can be seen that the white cardboard printing characteristic curve basically in Manila board below, say understand card order adjust density error is relatively small. Visible, white cardboard order tone reproduction performance better than the gradual reproduce the properties of Manila board. 23阶调密度反差对比分析2.3 order of density contrast analysis 另一种评价印刷品阶调再现的方法是评价印刷品的阶调密度反差。当具有较高的印刷相对反差值时，其实地密度又较高，印刷品的阶调再现性较好。同样，以品红墨各纸样的阶调密度反差(如图3所示)为例，Another evaluation print order tone reproduction method is to evaluate print order of density contrast. When has the high printing relative contrast value, actually to density is high, the reproducibility of the print is good. Similarly, the magenta ink gradual density contrast of each pattern (as shown in figure 3), for instance, 从图中可以看出，除荷兰白卡纸以外，两种白卡纸(亚太白卡纸、太阳白卡纸纸)的相对反差值，及其对应的实地密度值均不同程度地高于其他几种灰底白板纸的相对反差值及其对应的实地密度值(荷兰白卡纸除外)。这说明白卡纸的阶调再现性能比灰底白板纸相对要好。Can be seen from the graph, in addition to the Dutch white cardboard, two kinds of white cardboard sun (and the white paper, white cardboard paper) of the relative contrast value, and its corresponding field density values are higher than other several Manila board in different degrees of relative contrast value and its corresponding density (except white cardboard in the Netherlands). This say understand card order adjust playback performance is better than Manila board relatively. 上述3个不同的角度的研究分析，说明白卡纸比灰底白板纸的阶调再现性能好。但是在从这3个不同角度所做的研究分析中，荷兰白卡纸是一个例外情况，其在相对反差、实地密度、网点增大、阶调再现等方面，甚至要比最差的灰底白板纸还要差。经过查阅相关资料得知，荷兰白卡纸是一种普通白卡纸，它与上述的亚太白卡纸、太阳白卡纸不同，亚太白卡纸和太阳白卡纸都属于俗称为“铜白卡”一类的白卡纸，这种白卡纸是在普通白卡纸的基础上，经过施胶、涂布、压光等工序获得类似于铜版纸的比普通白卡纸高得多的平滑度、光泽度等表面性能。正是因为荷兰白卡纸只具有甚至比普通灰底白板纸还要低的平滑度、光泽度等表面性能，才造成荷兰白卡纸具有相对较差的阶调再现性能。但由于荷兰白卡纸不像其他铜白卡纸那样有着与灰底白板纸相类似的应用领域，所以，作为一种例外，荷兰白卡纸的特殊情况并不会影响到本实验的研究结论。The above research and analysis of three different point of view, than Manila board said understand paper order
