Vector line art: Common examples are graphs and charts created in illustration programs.Standard fonts include Arial, Helvetica, Times, Symbol, Mathematical Pi, and European Pi. Vector graphics are resolution independent and can be sized up or down without quality loss. Vector images are typically generated using drawing or illustration programs (e.g., Adobe Illustrator) and are composed of mathematically defined geometric shapes-lines, objects, and fills. The suggested minimum resolution is 300 PPI at publication size. Halftone: Common examples are color or grayscale figures containing images only with no text or thin lines.The preferred resolution is 600–900 PPI at publication size. Combination halftone: Common examples are color or grayscale figures containing halftone and line-art elements.The preferred resolution is 1,000–1,200 PPI at publication size. Monochrome (1 bit) images: Common examples are graphs and charts made of solid black and white with no gray values.Some of the common raster file formats that cannot be accepted are GIF, BMP, and PS. Raster images can be classified as monochrome (line art), halftone, or combination halftone. Submitted raster (i.e., pixel based) images must meet the minimum resolution requirements. Low-resolution images are one of the leading causes of art resubmission and schedule delays. Native file format of popular image editor. Use high-resolution/high-quality compression settings when created. Use standard fonts (base 14) to avoid potential delays due to missing fonts.Ĭan contain vector and raster information. If Max or High quality settings are used, then JPEG is an acceptable format for print and online.Ĭan contain either vector or raster information. This means in order to achieve smaller file sizes some quality is lost. Raster file format that uses an adjustable lossy compression system. Can contain vector and raster information.
