Printing knowledge that graphic designers must not be unaware of [Buke Book]

The printing factory tells you the printing knowledge you need to know about graphic design: images, bleed, text, color blocks, spot colors, stencil lines, output, files, and samples …..

1. The image should be at least 300dpi, otherwise it is prone to mosaic phenomenon, which directly affects the printing quality.

2. Bleeding is required for every document. During the printing process, there may be situations of inaccurate registration and cutting. The bleeding is usually 3 millimeters.

3. Text, set the black position to K100, do not use four-color black text as it may cause issues such as bleeding, exposure, and overprinting;

Color block, if it is a large area of black, set it as K100, C30, and pure K100 will appear gray when printed;

Spot color, when using spot color, we recommend using a little bit of explosive fertilizer. If you are not clear about the company's standards, you can ask the printing company for help.

4. When making documents, especially boxes, we often need to use beer lines. Because products that do not require binding still need to be made into finished products, corresponding beer thread files need to be used to make cutting or folding molds for the finished product samples. Like a box, with folding and cutting positions. We require the folding position to be made into a dotted line, while the cutting position should be made into strength. And all beer line files must be made into special color overlay printing. Because the beer line does not output.

5. When outputting, be sure to avoid low pixel images and ensure that all fonts are embedded.

6. Provide files to the printing company. You can provide the final PDF file or files from design software such as CDR. If it is a PDF file, please make sure it is an OK file. And the files for designing software must provide all the images and fonts used to the printing company.

7. For sampling, printing companies will provide a digital sample, please make sure to proofread it carefully. At the same time, please also request the printing company to provide a final set of blue paper (prepress sample) for careful inspection. Even if you provide a PDF to a printing company, there is still a risk of errors in different systems.
