The hottest packaging design and printing technolo

  • Detail

Packaging design and printing technology complement each other

one of the most important principles of packaging design is that design must be achievable in production. Prepress printing technology is the most closely related to print. The ever-changing computer design and prepress printing have made the traditional hand-painted design a history. Network transmission and digital printing have also opened up design ideas and enriched design means for designers, but many new problems have emerged. Many technical factors have never been encountered by art designers in the past

packaging design is a systematic work, involving many current factors, such as materials, structure, graphic design and manufacturing technology, which is by no means as simple as drawing an image. Therefore, packaging design in developed countries is usually completed by a team. There are not only packaging professionals who understand materials and structures, but also plane bamboo powder designers, salespersons and engineers from production enterprises to participate in the opinions, and strive to make the design perfect and can be achieved in production

there are some misunderstandings in the practice of packaging design in Chinese enterprises, which are mainly manifested in emphasizing plane and neglecting structure; Emphasize the design effect and light the manufacturing process. The direct cause of this problem is that the packaging design in China is mainly completed by art designers. These people are almost all born in art, and have great limitations in their understanding of materials, structures and processing technology. The continuous emergence of new materials and processes can broaden the creative space of designers, but it is also a challenge. The rapid development of new design means, printing methods and prepress technology also has a profound impact on the design activities of designers. New technologies such as computer design, networked transmission and digital printing directly affect the design work of designers. Therefore, packaging designers must be clear about the possible problems in the design process in the new environment. Before using the computer for page design, we should discuss with the prepress service provider and printers to decide whether to use hard copy documents or electronic documents. If you decide to use electronic documents, the font is the main factor that determines whether the design operation can be displayed when outputting. Whether to choose TrueType font, postscript font or Unicode font must be discussed with prepress service providers and printers to avoid possible problems in the output process of the font used. If possible, convert fonts into graphics in EPS (compressed page description file) files

for prepress service providers, the general problem is the placement or page description errors caused by fonts when importing EPS files. But avoid nested EPS files. EPS files containing other EPS files can cause output errors or increase output time. The problem is simplified by copying from one EPS file to another and populating elements instead of using the import or insert function. The use of inverted Fonts is widely used in all kinds of metal, non-metal, composite materials, medicine, food, wood, copper, aluminum, plastic profiles, wires and cables, paper, film, rubber, textile, aerospace and other industries. The use of inverted Fonts is often used, but it should be used with caution. Most inverted fonts are hard to read. Be especially careful when reversing fonts by processing color images. These images usually contain light and dark areas, which makes the inverted font difficult to read. Please refer to the output section and the technical manual for more information about trapping. Use a prominent color in the shaded part of the font, with at least 70% of the dot and face meridians

in addition, to ensure that the inverted font is readable, we should also avoid using small fonts or fine fonts for most vehicle enterprises. The font size shall not be less than 6 points or the thinnest part of characters shall not be less than 0.007 inch. Sans serif fonts and bold fonts are the best choices for reversing fonts. OPI or apropi (open printing interface) or APR (automatic image replacement) is the most accurate way to locate the output image of the page. If the prepress service provider supports OPI or APR, they will scan the image for you and give you a low resolution image to locate the page output file. When you send the job to the prepress service provider, their software will automatically match and replace the low resolution image with the high resolution image. This workflow [encyclopedia] can provide you with smaller documents, which can be operated faster and easier. See the page output section for more information about using OPI and APR documents. The influence of post-processing on output should be considered in the planning and design stage. For example, what kind of film covering material is used, and whether special effect treatment is required, such as bronzing, embossing, silk printing, coating, etc

in addition, if more post-processing is required, the operation time should also be considered to allow time for completion. Printing on digital printing machine as the industry is gradually developing towards full digital printing workflow, digital printing has become more and more widely accepted
