ASCII Outputs image data as plain text. This is the most compatible format, but it transmits (or saves in files) the largest amount of data. Binary Outputs images as binary data, which might not be compati- ble with all printers and networks. Binary data is half the size of ASCII data. Level 2 ASCII Outputs images in an ASCII format that is compati- ble with PostScript Level 2 devices. This produces files that are approximately 20% smaller than regular ASCII PostScript files. RLE Outputs images using Run Length Encoding compression. This format is compatible with PostScript Level 2 devices. This form of compression is most efficient when documents contain images that have large areas of flat color. JPEG Outputs images using JPEG compression. This format is compatible with PostScript Level 2 devices. JPEG compression requires more system memory and more processing time at the printer than other compression methods. However, this format achieves the fastest printing results with continuous-tone (photo- graphic) images and documents containing transparency effects. Printing proxies Print Proxied Images at Full Resolution Prints the high-resolution images that are linked to the proxies in the document. Canvas outputs the images from the linked files on your computer. If you do not select this option, Canvas prints proxy images rather than the high- resolution images. This is faster and could be adequate when you are proofing other parts of a document. Transparency Rendering Choose an option in the Transparency Rendering menu to specify how transparency and SpriteEffects will be rendered (converted to pixels for printing). Smallest Area Renders the area inside the bounding box of all transparent objects. This generates the least amount of additional data to print transparency effects. Do not choose this option if you are printing in color on non-PostScript printers and the document has vector and transparent objects that share the same color, because these printers will not match the colors precisely. In some cases, non- standard PostScript printers might produce a slight pixel shift between a transparent and non-transparent area of a vector object. If this happens, select Complete Area. Tip By default, Canvas uses JPEG compression for printing imag- es. This can reduce the amount of data sent to the printer. If a network print spooler reports errors with a JPEG data stream, select Images: ASCII or Level 2 ASCII and try printing again. The Images setting affects print- ing of images and rendered effects only.
