As soon as you have written 30 to 40 pages, please make a sample file from this to be tested so that we can make sure your files will output properly. The sample file should consist of 8 to 16 pages and include samples of all elements that will be in your book. This includes illustrations, tables, screen dumps, and the like. If you need typesetting specifications, please contact your editor. Our designers can supply you with basic specs and also frontmatter specs, if needed.

For all titles to be supplied as disk ready for the printer, please transmit the following to your editor:

• All PostScript files on transportable media (SyQuest, Optical, Floppy, etc.) or via FTP
• Laser printout from PostScript files that exactly matches the disks, at 100% size
• Completed copy of "File Specifications" form (PDF file, 11K)
• Complete file listing
• All printer fonts
• All illustration and/or photos (as EPS and TIFF files or hard copy)

We prefer PostScript files. We can also accept files from page layout programs such as Quark, Pagemaker, or LaTeX, or simple word-processing files.

PostScript files should have printer fonts embedded in the files if possible. Submit final hard copy laser proofs from PostScript files. In addition to the PostScript files, supply application files with screen and printer fonts on a separate disk, clearly marked "application files." These will be held at Wiley in case a late correction is needed. It is preferable for you to send any necessary revised files, rather than for us to correct the original files here. Revised files should not use the same file name as the original file and should always include the suffix or prefix "R-1, 2, etc" and effective date of revision. Send only those files that have been revised, not another complete copy of the job. Always include a new hard copy proof of the revised file.

Prior to saving the file to PostScript, you must install the printer driver that is compatible with the printer's output device. We can provide you with this information and the printer can provide you with the driver, if necessary.

We can accept application files and have them PostScripted. Remember to submit screen and printer fonts and hard copy.

Be sure to include all blank pages in your files. These pages should be left entirely blank. Make sure that folios do not appear on blank pages. Include blank pages in your hard copy--but mark these "BLANK PAGE" clearly.

Most printers prefer trim marks on your hard copy, but these should be turned off in final files. Please check this before sending the test file.

Each file should have a unique file name. Try to use useful names, including your initials, e.g., pdch1.doc. File names should follow the DOS convention, if possible, i.e., up to 8 characters (preferably letters and numbers, no spaces or slashes) and a dot ("."), followed by a three letter character suffix/extension, indicating the file type, such as .tif, .eps, .doc, .tex, etc. Avoid using symbols in file names.

Screens in boxed material or in art should be no less than 10%. They should be no more than 20% for 1/color books. Rules should not be thinner than 1/2-point; otherwise, they may not print out.

Illustrations and/or photos can be supplied on disk or as camera copy. Copies of all images should be included on the laser proof. Please mark images on the proof as LIVE if final, high-resolution files have been merged into the page. Mark images as FPO (For Position Only) if we need to do the merging. Place a window in the page for merging the art, but do not set a ruled box as a place-holder. All art must be clearly labeled with reference numbers that correspond to the markings on the FPOs included in the electronic files.

It is important to remember that TrueType fonts cannot be used with art.

If supplied on disk, photos should be supplied as TIFF files, scanned at 300 dpi at final size. All photos should be cropped and scaled in a program such as PhotoShop before importing into the page. If we have to scan any photos for you, include on the label the percentage enlargement or reduction and any special handling instructions. This can also be done on a tissue overlay.

Illustrations should generally be supplied as EPS files. Please also send the application files on a separate disk in case we have to make any revisions to the files. Adobe Illustrator and Aldus Freehand files are acceptable (Mac or IBM). Please send a sample in early to test. If you have questions about any other drawing programs or about illustration specifications, your editor can put you in touch with Wiley's Illustration Department. Screen dumps should be supplied as TIFF files; they should be sized in PhotoShop before importing into the page. Mathematica art should be tested in advance.

You should generally not use JPEG compression for any files, because this occasionally results in the loss of information. Most of our printers can handle LZW Compression (which is available in PhotoShop), Stuffit Delux, or Zip, but please confirm before you use any compression package.

Adobe Type 1 and Multiple Master font formats are acceptable. Do not use TrueType fonts. Adobe Type 3 fonts may or may not output properly and should be tested ahead of time. On the Macintosh or PC, avoid using any system fonts, such as those named after cities, e.g., Chicago, Monaco, New York. If you inadvertently use these in a file (even if you delete the text), you can cause errors. If possible, avoid applying bold or italic type attributes available in the type menu or type manipulation palette. Instead, choose the actual font name from your font menu. For example, instead of picking Times Roman and italicizing a word or phrase, switch to the font Times Roman Italic. Even though it may look good on your laser printer, your film could come out with the font in its regular weight or in Courier.

Remember to list all fonts used in imported EPS graphics on your font listing.

If you customize fonts, you must provide us with the screen and printer electronic font files.

Include printer fonts with your files. If possible, they should be embedded into PostScript and EPS files. We use vendors who own the entire Adobe type library. According to the licensing agreement of Adobe, it is legal for you to send your fonts to a vendor as long as that vendor already owns the fonts. If you use any non-Adobe fonts and you cannot embed the font in PostScript files, our vendor may have to purchase the font and you will be billed accordingly. If you send customized fonts, they will be discarded after imagesetting.

If you have any questions or need help with any of the processes mentioned above or would like more information on how to FTP your files, please contact John Wiley & Sons Technical Support at techhelp@wiley.com.
