数字印刷设计可不是那么简单的!

数字印刷的大优势是它对原稿的处理,它能够对原稿的使用达到大化。彩色数字印刷在复制原稿时,能达到胶印印刷质量效果。如果数字印刷不能处理好原稿,就要从一张高质量的原稿入手,并且以合适的像素扫描,并用高质量的扫描仪,能常以300dpi.可以获得满意的效果。由于不是胶印,所以还应该注意它的亮调和暗调部分。

The greatest advantage of digital printing is its handling of the original manuscript, which maximizes the use of the original. Color digital printing can achieve the effect of offset printing quality when copying the original manuscript. If digital printing fails to process the manuscript, it is necessary to start with a high-quality manuscript, and scan with suitable pixels, and use high-quality scanner. 300dpi. can often get satisfactory results. Because not offset, so it should be noted that it is the bright and dark part.

数字印刷不像胶印,它通常不能使用同一种类的纸。In-di go E—印刷机要求对纸张进行预处理。基于Xeikon的印刷机使用卷筒纸,并不是所有的纸张都有卷筒式的。务必记住,这种纸必须能够持有负电荷,一种表面光滑、极为贵重的白色纸张是数字印刷的佳选择。由于上光剂不会被连贯地粘住或被擦掉,可以避免再循环的物料被损坏,湿度也会破坏色彩的复制。另外,切记,在工作运行前,确保至少24小时内有足够的纸张在厂房内。

Digital printing is not like offset printing. It usually doesn't use the same kind of paper. The In-di go E - printing machine requires the preprocessing of the paper. The Xeikon based printing machine uses a roll of paper, not all of the paper has a drum type. It is important to remember that the paper must be able to hold negative charges, and a smooth, highly valued white paper is the best choice for digital printing. As the glazing agent will not be coherently bonded or erased, the recycled material can be avoided, and the humidity can also destroy the reproduction of the color. In addition, be sure to ensure that there is enough paper in the workshop for at least 24 hours before the work is run.

数字印刷不能够印刷网点色彩(除了靛青6-颜色的版本),使用PATONE TM Spot-to-CMYK图表能够发现CMYK的对等色,你能够为许多PANTONE TM色产生合理的代替成分。很厚的上光剂(增色剂)覆盖法经常呈现一种发光现象,看起来像是金属油墨。

Digital printing to color printing dot (except indigo 6- color version), using PATONE TM Spot-to-CMYK chart can be found peer color CMYK, you can have as many PANTONE components instead of reasonable color TM. A very thick glazing agent (color enhancer) overlay often presents a luminescent phenomenon that looks like a metal ink.

处在基于色调复制的设备上,大面积的实地印刷是普遍的问题。它们可能由于纸张表面的电荷及电荷自身的变化。则在某种程度上,单张纸表面的静电荷也发生了变化,导致在实地块上留下条痕和不平实的颜色,而被更新的系统就不会出现这种问题。通过使用Photoshop或其它软件在实地处产生杂点。与旧的印刷机相比,新的印刷机就很少出现这种问题。

Large area printing is the most common problem in equipment based on hue duplication. They may be due to the change in the charge and charge of the surface of the paper. In some extent, static charge sheet surface is changed, which left plain color and streak in the land, and the system is updated does not have this problem. Use Photoshop or other software to produce clutter in the field. Compared with the old printing press, the new printing machine rarely appears this problem.

反之,如果要想获得大面积的黑色实地,就用一种黄、品、青和蓝的油墨按不同的比例组成的浓黑墨。建议与你的供应商一起合作去发现、寻求佳的油墨数量比。试着以60C、40M、40Y、100K或者以40C、20M、20Y、100K的比例调色,使用所有的四色,而不仅仅像胶印所用的C墨。

On the other hand, if you want to obtain a large area of the black field, black ink with a yellow, magenta and cyan and blue ink according to different ratio. It is recommended to work with your suppliers to find and seek the best ink quantity ratio. Try to use 60C, 40M, 40Y, 100K or the proportion of 40C, 20M, 20Y, 100K to use all four colors, not just like the offset ink used in offset.

数字印刷可以400~600 dot/in地操作,通过产生网格来模仿色调点。因为从原稿较少的网点开始,所以网格在尺寸上受到所选择的色调线和可获得的网点量的限制。如果仅能得到一个有限的可获得的阴影量,则在整个阶调和混合色中的平滑过渡是困难的,增加杂点(在Photoshop中),就允许数字印刷设备的一些不太显著的变化,从暗调到亮调观察其叠印色

Digital printing can be operated at 400~600 dot/in to imitate tonal points by generating a grid. The grid is limited by the selected tonal line and the available dot volume in size because of the start of a less original site. If you can only get a limited amount of available shadow, in the tone and smooth transition of the blend color is difficult, the increase of noise (in Photoshop), some of the less significant change allows digital printing equipment, light from the darkened to observe the superimposition
