凸版印刷套印的解决方法

1、印版底托存在不坚实,且平整度、抗压强度比较差致使的套印存在一定的差错

1, there is a certain error in the overprint of the printing plate, which is not solid, and its flatness and compressive strength are relatively poor。

六合在线凸版印刷所选用版托的硬度和精度如何,在一定程度上影响着产品的打印精度。如果选用传统的胶合板,充当大幅面实地凸版印刷的版托,那么因为胶合板短少平整度和牢度,抗压功用差易发生紧缩变形,这么在打印过程中,一定因压力不均或底托真假纷歧,这就很简单使打印品版面变形,构成印出版面大于实习版样。

To some extent, the hardness and accuracy of the printing plates used in letterpress printing affect the printing accuracy of the products. If the traditional plywood is used to act as the plate of large face plate printing, the compression function of the plywood is very poor because of the short evenness and fastness of the plywood. In the process of printing, it must be disproportionate due to the uneven pressure or the true and false bottom, which makes the print print out of the layout and form the print. More than the internship version.

六合在线二、调墨不当、油墨粘度太大,致使印张前规方位不稳定

Two, improper ink adjustment, too high ink viscosity, resulting in instability of pre printing position.

坚持油墨适度的粘性,是完结打印、保证印品质量的重要条件。但是,油墨粘度没有一个规范规矩,也无法统一出一个规范来。打印中应根据打印材料特性、打印版面规划情况,凭阅历酌情调整油墨的粘性为防止这种缺点发生,打印吸墨量较大的图版产品,可根据油墨的粘稠度情况,酌情参与恰当的去粘剂或调墨油,可减少油墨对印张粘拉力,保证打印精度。

六合在线Adhering to the proper viscosity of ink is an important condition for printing and ensuring the quality of printed products。 However, ink viscosity is not standardized, nor can it unify a specification。 Printing should be printed on the basis of the characteristics of the printed material, print the layout of the layout, and adjust the stickiness of the ink according to the experience to prevent this defect from happening, and print the plate with a large amount of ink absorption。 It can take part in the appropriate adhesive or ink transfer oil according to the viscosity of the ink, which can reduce the adhesive force to the printing ink and guarantee the beating of the ink。 Printing precision。

三、滚筒咬纸牙失调致使的印张定位存在差错缺点

Three。 There are errors and defects in the printing location caused by the maladjustment of the rollers。

打印实地版,如果滚筒咬牙压力缺少时,那么,压印中的纸张就很简单从咬牙里往外滑移。这是因为版面油墨具有粘性,对印张发生一定程度的阻力。如有时印张进入滚筒咬牙后,咬牙闭合叼纸霎时间,印张的一端会出现微量撤离情况,所以便发生了打印歪斜表象。

六合在线Printing the field version, if the pressure of the roller is missing, then the paper in the embossing will simply slip outward from the teeth。 This is because the ink is sticky and has a certain degree of resistance to printing。 For example, sometimes, after the opening of the press, the bite of the tooth is closed, and the end of the press will have a trace of a trace。

四、打印压力调整过大使印张

Four. The printing pressure has been adjusted to the Ambassador

从咬纸牙方位滑移,发生套印不准打印压力是完结印迹均匀转移的作用要素,志向的打印墨层来源于适度均衡的打印压力。一般来说,承印物表面粗糙、打印幅面大,打印压力也得相应加大。

From the slip of the bite of the tooth, the inaccurate printing pressure is the essential factor for the uniform transfer of the imprint, and the ideal printing ink layer is derived from the moderately balanced printing pressure。 Generally speaking, the surface of the substrate is rough, the printing area is large, and the printing pressure has to be increased correspondingly。

这是因为一方面打印压力过大会使印张变形,致使打印品版面出现拉大表象,致使套印不准;另一方面,打印压力太大,压印时,一定对滚筒上的印张发生压榨性拉动力,致使印张从叼纸牙中往后扭拉而滑移,这就会使印张前规矩位不稳,出现偏小情况为防止这种不良成果发生,图版打印的压力调整,应在版面供墨量正常的情况下,由轻而重逐渐加压,这么才华较准确调到恰当的打印压力,然后保证打印质量。

This is because the printing pressure has passed through the assembly to make the printing press deformed, causing the print print to appear in a large image, causing the inaccuracy of the printing. On the other hand, the printing pressure is too big. When the press is impress, it must press the press on the press on the roller, causing the press to slip from the teeth in the teeth. The moment is unstable, and there is a small situation in order to prevent this bad result. The pressure adjustment of the print print should be gradually pressurized by light and heavy in the case of the normal print of the plate, so that the talent is more accurately adjusted to the proper printing pressure, and then the printing quality is guaranteed.

五、把好包衬技术技术关,防止产品打印变形构成套印不准

Five. Ensure the printing technology of the package and prevent printing distortion.

济南包装印刷包衬是完结版面印迹转移的桥梁,对打印精度具有一定的影响作用。因为设备规划上的差异,对包衬厚度的需求也有所不同。若包衬厚度不行,产品的版面纵向标准一般小于所对应的印版长度;要是包衬厚度逾越设备规矩参数,所印出的版面则大于印版实习幅面,这是影响打印精度的一个要素。

The packaging and printing lining of Ji'nan is the bridge for the printing of finished prints and has a certain influence on the printing accuracy. Because of the difference in equipment planning, there is also a different demand for the thickness of the lining. If the thickness of the lining is not enough, the vertical standard of the layout is generally less than the corresponding plate length. If the thickness of the package is overstepping the parameter of the equipment, the printed page is larger than the plate practice amplitude. This is an essential factor affecting the printing accuracy.
