Printing is everything on the earth. It is like experimenting in a laboratory, understanding the characteristics of different materials, and trying constantly to experiment with the material technology that best suits your design. If you do not understand the printing process and paper materials when designing, this article counts the relevant knowledge about printing documents, printing paper, printing colors, and printing processes.
First Key factor — Printing (Printing, Graphic Arts, also using Graphic Communications, that is, graphic communication) is to transfer text, pictures, photos, anti-counterfeiting, and other manuscripts through plate-making, inking, and pressurizing processes, so that the ink is transferred to paper, textiles, plastics, etc. Technology for copying the contents of manuscripts in batches on the surface of materials such as leather, PVC, and PC. Printing is the process of transferring the approved printing plate to the substrate through printing machinery and special ink.
At present, PDF is the most convenient file format for communication between customers, printing houses, and colleagues. The formats of advertisements and media files submitted to newspaper and magazine publishers are also based on PDF, and the final output file of the printer is also high-resolution. PDF file.
Adobe's Acrobat, InDesign, Illustrator can save PDF files. In order to avoid repeatedly modifying the file settings to affect the design process, what needs to be done before starting the design is to optimize the compression program with the predefined settings. In Indesign, click PDF Preset→Print Quality. After customizing the PDF settings, click File→Export, select the PDF format, and set the cropping, bleeding, and printer registration marks in a pop-up window. Check the file settings again in Acrobat to make sure it is correct.
Font embedding is a careless designer must remember. If the font cannot be embedded, it is usually omitted in the folder or restricted by the printing house. So after opening, the font will be replaced. If your design is floral style, and the printed version becomes traditional Song style, which is sad. So remember to embed fonts when exporting files. The preflight check function in InDesign and AI can help us avoid errors.
The choice of paper is definitely a part of the design process that needs to be considered. The thickness, texture, and color of the paper will affect the feeling of design image transmission. In the process of making a sample, you can choose several more papers to ensure the effect.
Paper is calculated in grams (g) or grams per square meter (g/m²). The thickness of the paper is measured in calipers or millimeters, but it is not that the thicker the paper, the better the quality.
The opacity of paper refers to the degree to which text or images can pass through, and it depends on the density and thickness of the paper. Professional paper companies will provide their data or experience for your reference.
Different paper surfaces affect the brightness of printing inks. The matte paper will absorb the ink on the surface, and there is basically no reflective gloss. Matte paper is used to print text, such as newspapers, books, etc., for easy reading.
However, the ink will stay on the surface after being printed on glossy paper, so more light shines on the paper under the font, the light is reflected and reflected, and the color will be deeper and stronger. This paper is suitable for book covers, magazines, brochures, and outer packaging. and many more. Glossy paper is a paper between rough and glossy. The color of ink on glossy paper is not as strong as glossy paper, and the surface is not shiny.
The role of the paint and polishing agent is to protect the ink and enhance the effect of the ink area.
1) Varnishes: A printing coating that can be mixed with other inks or used alone. It can be used on matte paper, glossy paper, and glossy paper.
2) Ultraviolet curing coating (UV Coating), commonly known as UV: it is applied with liquid and then cured by ultraviolet radiation. This kind of coating can be used on matte paper and glossy paper, and it can be used for precise partial coating or full coverage.
3) Water-based matte, satin, and gloss paint are more expensive and are often used as the last layer, so they can only cover the entire surface.
4) Laminates are plastic interlayers or transparent liquid layers in the paper, which have a protective effect.
Printing or printing color cast is the biggest headache for designers when outputting. The printed materials we see are composed of three elements: light, paper, and ink. When the budget is tight or when specific colors are used, monochromatic printing is used.
For example, many brands or companies use specific Pantone colors in their printed works, which can effectively maintain color uniformity to ensure the color recognition of the brand. It is recommended to buy a copy of the Pantone Chromatogram and choose the relative color number for printing.
Two and three-color printing allows Pantone colors to be mixed, overprinting two transparent inks can produce a third color, and printing black and white images with two-color and three-color printing can enhance the color effect.
Four-color printing is known as CMYK, cyan, magenta, yellow, and black, and countless colors can be created according to the ink ratio. This is what we are most common now.
Pantone System: The Pantone Color Matching System (PMS) includes a color reference manual and a color matching guide. You can choose the color by selecting the Pantone color code or input the accurate CMYK value. The printer comes with these guidelines and matching inks, so you need to see the manual.
