Pre-Print - Proof Production
Why does the text have to be turned into a curved "outline"?senseproductionlimited
The fonts used in the production of drafts are not available on every computer. If you use fonts other than the system have, you need to install them. If the other computer is not installed, it will not be displayed correctly. Converting the text means that the text is converted into a graphic form, which can prevent the font from falling off or shifting due to the problem of the system font.
Why make "bleed" for drafts/dummy?senseproductionlimited
"Bleeds" refers to the extra position of the printed finished size. During normal printing, there is a chance that the appearance of the printed product will be affected by the machine's inaccuracy. If there is no bleed, the default bleeding range is no printing (white paper). When the machine has a cutting error, the finished product may have white edges or part of the content will be cut off. In order to ensure the integrity of the printed product , it is necessary to make a "bleed" for the draft, which is generally set to 3mm.
Why do printed images need to be converted from RGB format to CMYK format?senseproductionlimited
Generally, most of the image colors we see on electronic screens use RGB mode, also known as "network color". The actual printing industry use CMYK color "printing color". CMYK mode can simulate the basic four-color performance of printing ink, and the printed colors will be more accurate. If printing in RGB mode, the machine will forcibly convert the color of the print file from RGB to CMYK during the printing process, changing the original color value, so that the color of the printed product becomes darker or has obvious color difference. The default setting of most design software on the market is RGB mode, so remember to set the image file to CMYK mode before outputting the file.
Printing Draft Requirementssenseproductionlimited
- Color Specifications: CMYK mode required
- Bleed and cutting position: At least 3mm bleed should be reserved on the four sides to avoid the content of the welt from being cut.
- Text: It must be converted into a curve and saved as a PDF file, so as to avoid missing words or missing pictures when outputting
- Ratio: File to finished product size must be 1:1
- 解像度：需設定為 150dpi
- File Format:
- Adobe Illustrator CS6
- Adobe Photoshop
- Adobe InDesign
- Adobe PDF
**The company is not responsible for proofreading the content of the draft, and does not take any responsibility for the authenticity, copyright or legality of the content of the draft.
Why does color difference occur?tiffanyelffThe color difference is mainly affected by the printing environment, color value and other factors. During the printing process, the ink will change the color of the printed product due to changes in ambient temperature and humidity. The same document may be printed multiple times before and after may also have a different color depth. The color value refers to the problem of up-conversion in the RGB and CMYK formats of the printed image. The picture is displayed in RGB mode on the screen, and the color is more vivid. The actual printing color mode is CMYK, which simulates the basic four-color performance of printing inks. When converting RGB design drafts to CMYK format, it is easy to cause distorted color problems, so there will be slight color difference between the actual printing effect and the screen display effect. At present, the problem of color difference cannot be completely eliminated in printing technology, and can only be controlled by playing and adjusting colors.
Why are folded prints prone to edge damage?senseproductionlimited
Whether the paper folding will have a damaged edge is mainly affected by the thickness of the paper. Generally, the thicker the paper, the easier it is to have this problem. Because the fibers of thick paper are more compact, it is easier to break and is not suitable for direct folding. Using thinner paper, adding a crimp or film can reduce the chance of paper breakage.
The impact of paper selection on the printed product?senseproductionlimited
Different papers have different color rendering effects, and the same file printed on different papers will have different printing effects and colors. Printed on paper with a base color (such as kraft paper), there will be greater color difference. In addition, processing on the paper, such as gloss or matte glue, can also affect the color of the finished product.
What is the difference between pantone color printing and ordinary printing?senseproductionlimited
Ordinary printing means that the machine mixes inks through CMYK (cyan, red, yellow, black) four colors during the printing process. Pantone color printing refers to pre-mixing the closest ink color with reference to the pantone standard Pantone Code before printing. Therefore, the color of the "pantone" printed product will be more accurate and uniform, but at the same time, the price is relatively high. "Pantone" are often used in big brands. For example, IKEA's commonly used blue is a specially customized pantone.
