March 18, 1987 Dear SIGGRAPH'87 Primary Author: Here is the author's kit for preparing your camera-ready copy of your paper for SIGGRAPH'87. Ten (10) two-column reduction mats are enclosed. The mats contain preprinted instructions for typing material onto each mat. An additional sheet of instructions specific to the SIGGRAPH'87 conference proceedings are also enclosed. Please read these additional instructions carefully. They are getting longer as we learn more about improving the quality of the proceedings. I would appreciate your help in following them. As noted in the instructions, please leave sufficient space on the first page in the lower left corner for the copyright notice to be stripped in by the printer. When your paper is complete, please ship it to me by Federal Express, using the enclosed waybill. Foreign authors (relative to the US) will be using an international waybill with the correct customs declaration. Please remember to sign and return the enclosed copyright form with your manuscript. Papers with multiple authors will require a signed copyright release form from each author. ACM SIGGRAPH will not publish any paper that is not accompanied by signed copyright clearance forms for all authors. You will receive a separate mailing to encourage you to submit an image from your paper for the SIGGRAPH technical slide set and/or proceedings cover. In past years, we have missed the opportunity to use images from the technical papers only because they were never submitted! Thank you for your assistance. I look forward to receiving your completed paper by April 30, 1987. Sincerely, RIchard J. Beach Production editor, SIGGRAPH'87 proceedings (415)494-4822 Beach.pa@Xerox.com enclosures: SIGGRAPH'87 instructions, ACM copyright form, Computing Review classification return Federal Express waybill, 10 reduction mats Instructions for SIGGRAPH'87 Authors Richard J. Beach Editor-in-chief, ACM SIGGRAPH Xerox Palo Alto Research Center 3333 Coyote Hill Road Palo Alto, CA 94304 (415)494-4822 Beach.pa@Xerox.com Enclosed are the reduction mats for your paper that has been accepted for the SIGGRAPH'87 annual conference. In addition to the instructions preprinted on the mats, please follow these guidelines. 1. The deadline is April 30, 1987 for receiving the reduction mats at Xerox PARC. I cannot guarantee that a late paper will make it into the proceedings. The schedules for color separating, proofing and printing the proceedings are very tight. Remember that the proceedings use 37 tons of paper and occupy a printing press for a week! To expedite delivery of your paper, I have enclosed a pre-addressed Federal Express waybill. For foreign authors, I have enclosed an international waybill with the correct customs declaration. Please telephone me with the waybill number when you ship your paper to help me track delayed or lost shipments (the waybill number is necessary for tracking). 2. There is an absolute limit of 10 pages. This limit includes everything for your paper  pictures as well as text. Please aim for an 8-page paper. Because each paper begins an odd-numbered page, your paper will always occupy an even number of pages (a 7-page paper will occupy 8 pages and not save any space). 3. The ACM copyright form must be signed by each author and returned with the reduction mats. Please remember to leave space on the first page at the lower left corner for the copyright notice. The copyright notice will be typeset and added just prior to printing. You can see such a notice in a proceedings from a previous year. 4. Please use the double column format for text throughout, even for your abstract and footnotes. The reduction mat will be reduced by 23% to achieve an 8.5 by 11-inch size. Please mark the page number and primary author's name in black pen only in the space provided at the bottom of each reduction mat. A brief check of the 34 accepted papers reveals that about 7 used daisy wheel printers, 13 used troff, 8 used TeX, and 6 used laser printers with formatters that I could not identify. If you have good macros for the proceedings, please offer them to me. A couple of style thoughts. Please use initial caps for paper titles, like ``Ray Tracing Mumble'' for example. Please include the authors' full names and institutions with the title and place addresses and phone numbers at the bottom of the first page. If you are using a typewriter or daisy wheel printer, please use a Prestige Elite typefont with 12 characters per inch. Please do not use a smaller typefont  the text when reduced will be too small to read comfortably. If an Elite font is unavailable, please use a similar Prestige font with serifs. If you are typesetting your paper, please continue to use the reduction mats. We do not have convenient facilities to handle ``at size'' typeset material; all of the running heads will be prepared assuming reduction mats. Please use a 10-point Times Roman typeface with 11-point leading (vertical spacing between lines). If Times Roman typeface is unavailable, please use a serif typeface. Please afix the typeset material with a waxer, or rubber cement, or two-sided tape (in order from best to acceptable). Please do not use single-sided tape over the material, as this creates visible artifacts that requires underexposing the page to eliminate the flaws, thereby reducing the constrast. 5. Please cluster color illustrations in a minimum number of places (one if possible). This place need not be at the end of your paper. Mount all photographs and color illustrations directly on the mats provided. Use glossy prints rather than matte prints for best contrast. The figures should all have appropriate captions. Please remove any unnecessary use of color from your paper. We will not mount or label your illustrations  each page must look exactly as you want it to appear in the proceedings. Please do not use Polaroid prints as they cause reproduction problems. 6. If you wish to supply color transparencies or color separations, please call me in advance. There are logistics to arrange with the printer and I need the extra time to arrange them. 7. Warning  the printer will make heroic efforts to make your color images look exactly like the image on your reduction mat. You are responsible for the quality of the color image! 8. Please use the ACM format for references (see Transactions on Graphics or Communications of the ACM). Each reference is a bracketed number [1], and the bibliographic citations are collected in a numbered list, alphabetized by surname of the primary author. Please use full first names to retain informality. Please use a consistent bibliographic citation to articles published in previous SIGGRAPH conference proceedings as follows: 1. Van Hook, Tim. Real-Time Shaded NC Milling Display. Proceedings of SIGGRAPH'86 (Dallas, Texas, August 1822, 1986). In Computer Graphics 20, 4 (August 1986), 1520.

Please contact me for any questions or problems at (415)494-4822 via telephone or at Beach.pa@Xerox.com via electronic mail. Thank you for helping to maintain the high standard of quality of the SIGGRAPH conference proceedings. I look forward to receiving your paper by April 30, 1987. Quick Checklist 1. I enclosed signed copyright forms for each author 2. I enclosed 10 or fewer reduction mats, each with page number and author written in pen at the bottom. 3. I left space on the first page at the lower left corner for the ACM copyright notice. 4. I submitted interesting slides from my paper to Bruce Brown. 5. Today is before April 30, 1987. 6. I avoided using single-sided adhesive tape to mount camera-ready copy on reduction mats. 7. I avoided using Polaroid prints. 8. I supplied using glossy prints. 9. I clustered color illustrations. 10. All illustrations have a caption and are mounted in place. 11. I used ACM style conventions for references. 12. I have telephoned Rick Beach at (415)494-4822 with the waybill number. 13. I'll never do this again!
