页面设计技巧
The following information includes best practices and tips for page design when prepping for printing.
失落的环节
Most page layout and illustration programs allow clients to place or import graphic files - typically EPS or JPEG - into them, and these placed files should always be included with the final document when sent to the printer or output bureau.
Do not "Stylize" graphics in InDesign or any layout program {such as negative, 对比, posturize, 重影, 等). Special effects like these produce better results when they are created in Photoshop or other effect-specific applications.
命名文件
逻辑地命名文件. 将文件名限制为尽可能少的字符. 不应使用前导和尾随空格或符号. Never name two files or images the same, even if they are on different pages.
页面设置
Ensure your design is on a page that is the final size you want it to be when finished. We are not able to resize files to different dimensions; this needs set up at the beginning of the design process.

书工作
Do not send single page documents, it is very time consuming to process them. Always design your document as single pages in reader's order, never printer's order.
不指定规则作为发际线
Many high resolution output devices interpret Hairline to be the minimum thickness of a line the device can draw. 与激光打印机相比, a high resolution imagesetter can image an extremely thin line that is unprintable on press. 如果需要细线，请将规则指定为 .25 or .5分而不是发际线违约.
流血
Any element that extends to the final trim edge needs to be extended to at least .125''(1/8''). 在设置文档大小时不包括出血吗. 渗出的部分应超过文件的边缘. 始终按照最终修剪尺寸创建文档(100%). Most printers use software to impose your files into press-ready layouts. This software depends on your documents to be created to final trim size. 如果你的最终尺寸是4x6，让你的文档(PAGE SETUP) 4x6. 不要把你的文件建在8 1/2x11的中间.
折叠
The most common mistake made when creating a folded brochure with a fold-out or roll fold is making every panel the exact same size. 正面和背面必须是相同的尺寸, but the fold-out panel must be slightly shorter to allow the brochure to lay flat. The same rule applies to a roll fold with multiple fold-in panels; each panel must be short as the pages roll inward.
被困
In most cases it is easier if the pre-press department performs any trapping required for output since printers have more information available to make proper decisions regarding the tolerances of the printing presses. 最常见的套印问题是套印不当. You should never assign a colored object overprint if it is over a black object. 黑色物体将覆盖有色物体. 唯一的例外可能是金属色的使用. You should check with your printing company about trapping specifications for metallic colors. 白色不应该被分配套印. 有颜色的物体会盖住白色的物体，然后它就会消失. 白色的物体和文字应该总是被指定为淘汰.
Clean up your documents before bringing them in to your service bureau. This includes removing any unused spot colors from your color palettes, 删除任何未使用的字体, 并消除粘贴板上文档之外的任何项目. These simple steps make it easier for us to output and less likely for a postscript error to occur. 不要用白盒子遮住不需要的元素. 删除它们. 不要把你的电脑当成打字机. 句号后不再需要加两个空格. Don't use the space bar when creating type in columns; always use tabs.
提示:
Beware of large areas of solid black when designing files for 4 color printing. 许多印刷机不能处理大面积的纯黑色油墨, 那些可以, often produce a black that is very dull-lookingin comparison to the rest of the colors on the page. This is because most colors are a mixture of colors whose lower density values add up to more than 100% (maximum amount for anyone ink color). The best way to deal with this is by creating what is known as a PROCESS BLACK. That is a mixture of 100% black with lower densities of two or more process colors. 例如，青色= 40%，品红= 30%，黄色= 20%，黑色= 100%.
彩色图像格式
所有彩色图像应以CMYK颜色模式保存. 不转换为CMYK, RBG图像不能打印. GIFs and BMPs are great for screen display and the Internet; however, 它们不适合印刷生产工作流程. 这些文件格式可能会导致后记输出出现问题. GIFs are index color instead of CMYK and will cause unexpected results. High resolution JPEG and EPS file formats should be used to avoid output problems.
决议
线条艺术的分辨率不应低于900-1200 dpi. Grayscale and 4-color should have a minimum resolution of 300dpi or double the line screen used. Always attempt to scan your images so they can be placed in the document at 100%. Halftones should have a dot of no less than 3% highlight and no more than 90% shadows. 大多数情况下, a resolution ratio higher than 2:1 will provide little or no improvement in the final result, 并且会延长成像时间, 这是要花钱的.
图像大小
试着扫描你的图像，这样它们就可以100%地放在文档中. 它们不应该大于150%，也不应该小于30%. As an image is enlarged in the page layout the resolution becomes lower, this means that if you enlarge an image large enough it will become low-res. 300ppi的扫描在200%的位置只会变成150ppi. 真正解决这个问题的唯一方法是重新扫描图像. 同样，当你缩小图像时，你会增加分辨率. 300ppi的扫描在50%的位置将是600ppi. 缩小图像不会对图像质量造成任何问题, but the image will take longer to print or cause the file not to print at all. Reduce your images in PhotoShop and place them at 100% to avoid prolonged imaging time.
斑点或CMYK颜色
If your job is printing in CMYK, be sure to convert any Spot Colors to Process Colors. This is especially important in illustration programs such as Illustrator and Freeland. You should not have any spot colors in any of your files UNLESS they are actually printing a spot color ink. 仅使用Pantone或自定义CMYK颜色. 不要使用RGB, HSL或任何其他非标准颜色模型. 避免使用默认专色，如红色、绿色和蓝色. 删除所有未使用的颜色. 确保颜色名称在整个项目中保持一致. (PMS 485 will not output on the same plate as PANTONE 485 CV - the names must match exactly).
正确newbb电子
为适当的目的使用适当的程序. 不要使用绘图程序来进行页面布局, or a page layout program to do imaging operations such as rotating or silhouetting. 每个程序都是一个具有特定目的的工具. Don't use word processing programs for final output purposes, (ie; Microsoft Word). Four-color separated film cannot be output from them (though they work fine for color laser prints). Photoshop不应该用作最终的页面布局程序, 它可以创建不必要的大文件，并容易栅格化小类型.
