For every customized paper packaging box, the importance of pre press inspection is inevitable, and it will not be further discussed here. There are many standardized management methods for pre press inspection, and here is an information supplement for the previous textbook, which can also improve the pre press work and reduce the risk of product accidents to a greater extent.
The standard size of the barcode is 37.29mmx26.26mm, with a magnification of 0.8-2.0.
When the printing area allows, barcodes with a magnification of 1.0 or higher should be selected to meet the reading requirements. The smaller the magnification of the barcode, the higher the printing accuracy requirements. When the printing accuracy cannot meet the requirements, it is easy to cause difficulties in barcode recognition.
Usage of barcode
The universal product barcode generally consists of a prefix, manufacturer code, product code, and verification code. The prefix code in the product barcode is a code used to identify the country or region, and is authorized by the International Article Numbering Association, such as 00-09 representing the United States and Canada. 45.49 represents Japan. 69 represents Chinese Mainland, 471 represents Taiwan, China, and 489 represents the Hong Kong Special Administrative Region.
The product code is a code used to identify a product, and the right to assign the code is exercised by the product manufacturing enterprise itself. The product barcode. Finally, use a 1-digit verification code to check the correctness of the 1-12 digits from the left in the product barcode.
The main reason for using monochrome black in printing is to improve printing quality and efficiency.
Monochrome black, meaning that in CMYK color mode, the values of cyan (C), magenta (M), and yellow (Y) are 0, while the value of black (K) is 100
For packaging copy, monochrome black is usually used. If multi-color black is used, printing may result in inaccurate positioning!
Printing quality: Monochrome black is more suitable for printing than four-color fruits (i.e. CMYK all four colors reach 100% 6). Printing with four-color black is more difficult and prone to color distortion, while monochrome black, although not very black and slightly reddish, can provide better quality in printing, especially when printing small characters. Monochrome black can ensure clearer printing effects.
Cost considerations: Although monochrome black is not a very pure black color, it can meet most printing needs, especially finding a balance between cost and efficiency. Using monochrome black can reduce printing costs while maintaining good printing clarity.
It is very important to conduct a size check before printing, as it directly affects whether the final printed product meets the design requirements in terms of size. It is necessary to confirm whether the finished product dimensions in the design are consistent with the customer's requirements. If the design size is not a regular size, it is necessary to specifically inquire with the customer for confirmation.
Bleeding setting: Bleeding refers to the additional reserved space at the cutting position, usually with an extra 3mm on each side, to ensure that the edges of the printed material are neat and beautiful after cutting. For example, if a design size is 210mmx285mm, considering the bleeding position, the actual design size should be 216mmx29lmm
Dimensional inspection of special processed products: If the product requires special processing, such as packaging design, it is necessary to check whether the dimensions of each part match, ensure that symmetrical elements are symmetrical, and reduce the elements that need to be reduced to the correct size.

Pre press output print self-test
After printing, we can check each item one by one and organize a set of methods ourselves, such as checking the size first, checking the text, checking the barcode, etc. Each time in a unified order, it can greatly reduce the probability of errors!
Knowledge Point (1)
Pre press output print self-test is an important step that involves judging the status and performance of the printer through its self-test page to ensure print quality. This process includes checking whether the print content is centered, paper correction, print density setting, paper feeding accuracy, print head cleaning, and other aspects. Through these self checks, possible issues with the printer can be identified and resolved in a timely manner, thereby ensuring the quality of the final printed product.
Knowledge Point (2)
Printing self-test can effectively detect common issues such as content not being centered, text errors, color discrepancies, and so on!
Packaging design has relatively high requirements for font copyright. As designers, we should try not to use paid fonts. Currently, most companies use fonts such as SiYuan Heiti series and SiYuan Songti series. In addition, you can use some mini programs to find fonts, such as (Font Plus)
Attention should be paid to copyright issues when using fonts to avoid infringement.
As a work of art, when a designer creates a unique style that reflects their personal style and has aesthetic value according to the inherent writing rules of Chinese characters, this carefully designed font can be protected by the Copyright Law.
Therefore, even system built-in fonts such as Microsoft Yahei require formal authorization when used for commercial purposes.
In addition, changing the font form does not mean that it can be used without original authorization, free downloaded fonts do not mean they can be commercially used for free, and system built-in fonts do not mean they have obtained commercial authorization. Therefore, it is very important to enhance awareness of copyright protection, clarify the scope of authorization, and conduct copyright ownership checks before use.
Check if the image itself contains copyright information, such as author name, copyright year, etc. These pieces of information are crucial for determining copyright ownership. Use search engines for retrieval, such as Google or Baidu, by entering keywords for images. If you see the same image on other websites, you need to further verify its copyright status.
Comparing original images, if you suspect that a certain image may be infringing, you can use software such as Photoshop to compare it with the original image. By comparing elements and colors Check if there are any similarities in terms of size and other factors.
Using copyright protection tools, there are many copyright protection tools on the market, such as Tineye, which can help you search and determine whether an image has been infringed upon.
Inquire with the original author or copyright owner. If you have any doubts, you can directly contact the original author or copyright owner of the image to inquire if they authorize or allow the use of the image.
The above is the final supplement to the pre press standardization inspection for ITIS packaging, hoping to help our customers.
