12、icrographics industry are used for the preservation and subsequent reproduction of color source materials. These materials include both colored and color-coded documents such as maps, charts, graphic materials, industrial and commercial catalogs, educational materials, engineering schematics, wiring

13、 diagrams, and a variety of other subjects. The microrecording in color of color source materials has been attempted since the origins of commercially applied microfilm because such documents lose information content when recorded on black-and-white materials. Until quite recently, material and proc

14、edure technology used for color micrographics had not progressed to a level that would permit the majority of the above-mentioned subjects to be microfilmed in color. Improvements in optical technology, reproduction and duplication procedures, and the resolution capability, long-term keeping propert

15、ies and dye stability of color microfilms (see Annex B) have added considerable breadth to the capabilities of color processes. Thus, there has been a corresponding growth of interest in color micrographics, its technology, advantages, and its present and future applications. This technical report o

16、utlines the present status of commercially available color microfilm processes, technologies and techniques, and will be revised as appropriate to keep abreast of the new materials and equipment introduced to handle them. Suggestions for improvement of this technical report are welcome. They should

17、be sent to Chairman, AIIM Standards Board, Association for Information and Image Management, 1100 Wayne Ave., Suite 1100, Silver Spring, MD, 20910.

In addition, alternative and auxiliary processes aid in the production of color mic

41、roforms. For virtue of this technical report, color photographic materials can be divided into two categories: negative-working (subject-image polarity is changed) and direct-imaging (polarity is retained). 4.2 Negative-to-positive process Continuous-tone as well as high-contrast black and white mat

42、erials can be used for the production of masters to which filters are added to provide color separations onto duplicate print stock. (See Note in Annex A.) Color negative materials are seldom used as viewer originals, but as negative intermediates. As microform masters (first generation camera origi

43、nals), they are printed onto a second generation print stock to obtain a positive image. Color negative materials provide automatic post-development masking for correction in contact or projection printing. (Masking is required when printing onto negative working, color print materials.) Negative fi

44、lm materials generally have a broader exposure latitude than direct 6 ASSOCIATION FOR INFORMATION AND IMAGE MANAGEMENT INTERNATIONAL ANSI/AIIM TR9-2000 - TECHNICAL REPORT - COLOR MICROFORMS positive materials, and, therefore, the negative-to-positive color print process can tolerate inaccurate first

45、 generation exposures to a greater extent, and can record longer tonal scale originals. Color print films are used to make positive color copies from color negative materials or from black and white materials printed with color filters. The wide variety of color negative materials available for the

46、recording of both short and long tonal scale originals renders the negative-to-positive color print procedure extremely versatile in regard to contrast manipulation, color balance, and tonal control. 4.3 Reversal process Color reversal materials produce a direct-duplicate image from the original thr

47、ough the use of a chemical reversal process. They can be used as first generation camera originals or as masters in a reversal print duplicating process. When used as a camera original, compensation must be made if the light source differs in color quality from that for which the film is balanced. R

48、eversal films are usually higher in contrast than negative films, but not necessarily higher in contrast than the products of the negative-to-positive process. A limited range of gamma values in these materials is available for the recording of both short and long tonal scale originals. Reversal fil

49、ms generally have narrower exposure latitude than negative films, and are less tolerant of inaccurate exposure. Reversal films are not premasked (due to the intended application as a direct-image film); therefore, certain duplication processes may require masking. 4.4 Direct positive process Direct positive color microfilms produce a direct image from the original without the use of a negative material or of a chemical reversal process. The direct positive technology used in color micrographic film is known as silver-dye bleach (see Section 3, Definitions, direct positive color films).
