条形码在印刷过程中存在的问题有哪些
作者:admin 来源:http://www.sdhzyw.com 发布时间:2018-7-18 12:02:51 浏览次数:277
在传统书刊中,印刷厂忽视了许多小细节。对于许多书刊来说,条形码的印刷是不可缺少的一环。然而,条形码印刷始终存在着一些问题:
In traditional books and periodicals, the printing shop has neglected many small details. For many books and periodicals, barcode printing is an indispensable part. However, there are always some problems in bar code printing.
1。不同书刊的条形码印刷尺寸。
1. The bar code printing size of different books and periodicals.
一些书由于其体积小,或者封面图形太多,位置不够放置条形码,从而随意降低条码大小,更终造成条码空件太小或太薄,无法读取扫描仪器。因此,在降低条码,需要使用特殊的设备来做微缩模型,通常只能降低到正常的80%条码。
Some books, because of their small size, or too many cover graphics, are not positioned enough bar codes to reduce the size of the bar code at will, and eventually cause the bar code space to be too small or too thin to read the scanner. Therefore, in order to reduce bar code and use special equipment to make miniature models, it usually only reduces to 80% bar code.

2。色条结合不当。

2. The combination of color strips is unsuitable.
由于条形码是由光线照射在物品上,空的反射率不同,所以条码扫描设备中的大部分光源都是红光,因此,白空黑的条形码是更容易读懂的。有些书的印刷成本降低了,封面上的文字只打印了一种颜色:红、黄、橙,条形码印刷也变成了白、红、白、黄、白、橙等,使得看不到条形码扫描器。
Because the bar code is irradiated by light on the object, the reflectivity of the space is different, so most of the light source in the bar code scanning device is red, so the white space black bar code is the easiest to read. The printing costs of some books have been reduced, and the text on the cover printed only one color: red, yellow and orange, and barcode printing became white, red, white, yellow, white, orange and so on, so that barcode scanners could not be seen.
当然,除了搭配白色的空黑色物品外,还可以选择黑色、深蓝色、深绿色、棕色,空颜色应该是白色、红色、黄色、橙色,这16种搭配是更好的选择。
Of course, in addition to the white empty black items, but also can choose black, dark blue, dark green, brown, empty color should be white, red, yellow, orange, these 16 collocations are the best choice.
3。自制条码胶片。
3. Homemade bar code film.
这是错误的,使条形码或复制条形码从原来的书,然后把它到盘子里。一般来说,条形码或条形码的拷贝是不合格的,这很容易导致条码扫描设备无法读取。
It is wrong to make barcode or copy barcode from the original book and then put it on the plate. Generally speaking, bar code or bar code copy is not qualified, which can easily lead to barcode scanning equipment can not read.
4。印刷纸、油墨及设备的选择不当。
4. Improper selection of printed paper, ink and equipment.
文章中的条形码和气隙非常小,印刷纸、油墨、设备印刷容易选择不易粘贴的版本,当粗化时,空条宽度大于正负30%时,扫描器无法读取。
The bar code and air gap in the article are very small, printing paper, ink, equipment printing is easy to choose the version which is not easy to paste. When the width of the strip is larger than positive and negative 30%, the scanner can not be read.
图书条码印刷,因此,更好选择胶印,选纸涂布纸、胶版纸毛少纸,印刷缸套不宜过软,当油墨流动性适中,以保证不糊版。条形码印刷应清晰、尺寸准确、宽偏差和印刷对比度在规定的范围内,可以是一本书的条码印刷质量。
Book bar code printing, therefore, the best choice of offset printing, paper coating paper, offset paper hair less paper, printing cylinder sleeve should not be too soft, when the ink fluidity is moderate, to ensure the non - paste. Bar code printing should be clear, accurate, wide deviation and print contrast within the specified limits, which can be the bar code printing quality of a book.
