2、nd certain packaging characteristics of motion-picture raw stock. The suggested location of this information on the manufacturers label is also specified. 2 Normative reference The following standard contains provisions which, through reference in this text, constitute provisions of this standard.

4、lm - Raw Stock - Designation of A and B Windings 3 Film identification 3.1 The physical specifications of the raw stock shall be contained in one sequential listing, preferably in one line but allowing a continuance on a second line if there are space restrictions. 3.2 The method of identifying the

5、cutting and perforating physical specifications and the sequence in which the information should appear when included shall be as follows: 3.2.1 The film shall be specified in its nominal millimeter equivalent. For example, the common, Page 1 of 5 pages currently available film widths are 8, 16, 32,

6、 35, 65, and 70, and designated as shown. 3.2.2 If the end-use width is narrower than the parent width, or if the frame is an intermediate or negative film whose subsequent print has an end-use width narrower than the parent width, the end-use width shall follow the parent width after a solidus; for

7、 example, 35/16, 35/8, and 16/8. Use of the millimeter abbreviation, mm, following the width designation is not preferred but is optional. 3.2.3 The number of rows of perforations in the parent width film shall be listed in the Arabic numeral followed by the letter R; for example, lR, 2R, 3R. 3.2.4

8、The perforation shape shall be indicated by a code letter or combination of letters. The letter designation for the perforation shape shall be as specified in the note or the appropriate film dimensions standard. 3.2.5 The perforation pitch shall be as specified in its appropriate millimeter equival

9、ent without the decimal point; for example, 3810, 4234, 4750, and 7620. It is recognized that it has been the practice to specify the perforation in its inch equivalent without the decimal point. Therefore, a manufacturer may include the inch equivalent of the perforation pitch in parentheses withou

10、t the decimal point; for example, 3810 (1500), 4234 (1667), 4750 (1870), and 7620 (3000). 3.2.6 The arrangement of rows of perforations shall be specified by numerals separated by a dash to indicate how the rows of perforations are CAUTION NOTICE: This Standard may be revised or withdrawn at any tim

11、e. The procedures of the Standard Developer require that action be taken to reaffirm, revise, or withdraw this standard no later than five years from the date of publication.

Hartsdale Ave., white Plains, NY 10607 (914) 761-1100 Approved July 27, 1998 ANSVCMPTE 184M-1998 placed on the film. This designation is necessary only when the film stock is wider

13、 than its end-use and more than one combination of perforation rows is possible. The total number of rows for the perforation type and end-use considered is determined by including all rows of all combina- tions. The perforation rows shall be numbered starting at the reference edge. The reference ed

14、ge is that edge of the strip nearest to the row of perforations which is retained on one of the slit prints (.e., not discarded in any subsequent slitting). The row(s) of perforations which is discarded will always be given by the number O. Negative or intermediate films which are not slit may conta

15、in the O-numbered row of perforations if that perforation row corresponds to the discard row of perforations in the subsequent print stock. 4 Spooling specifications 4.1 The roll length (which in some cases may be the usable length) shall be specified on the label and designated in feet and meters.

16、In lieu of or in addition to the separate designation, the roll length may be included as part of the sequential listing of physical specifications following the item designated in 3.2.9 with the length specified first in meters and parenthetically in feet; e.g., 304.8 (1 000). When the designation

17、of length applies to the slit width (not a usual practice), the designation SL shall follow the length specification. 4.2 Currently, there is no national standard nomenclature for the device (core, spool, reel, or cartridge) containing the film. If such standard nomenclature is derived, it should be

18、 indicated in the sequential listing or separately. For all films with nonsymmetrical perforation rows, there could be two different windings for the same numbered rows of perforations. Film perforated 1618 1-3 would be 1-3 regardless Of winding, but the winding could be Aor B, depending upon the lo

19、cation of the reference edge. 5 Suggested characteristics and speci- fications of the label 5.1 The label may be any color and of any suit- able material. The shape should be a simple geometric form and of a size consistent with legibility. 3.2.7 A designation of emulsion orientation shall be specif

20、ied. If the emulsion side of the film is in, it shall face toward the center of the wound roll, and the designation EI shall be used. If the emulsion side of the film is out, it shall face away from the center of the wound roll, and the winding designation EO shall be used. 3.2.8 The designation of

21、winding orientation is indicated only when a nonsymmetrical format is involved, and shall be specified as A or B in compliance with ANSVSMPTE 75M. 3.2.9 The designation M shall be included if the film has been striped with a magnetic coating for audio recording. Magnetic striping is usually placed o

22、n the base of the product; however, variations are possible when it is believed important to the end use. To identify the location of the stripe, the symbol MB may be used when the magnetic material is on the base side and the symbol ME when it appears on the emulsion side. 5.2 The line (2) of physi

23、cal specification (clauses 3 and 4 above) should be distinct and placed prominently in the upper half of the label. The line(s) may also be used on other parts of the individual or bulk film containers. 5.3 The manufacturers notices (e.g., warranty, disclaimer, open in darkness, safety film, etc.) s

24、hould be grouped together in one area of the label, preferably the lower portion. 5.4 The description of the film product should include the primary intended use of the film together with the manufacturers product code identification and trade name. Examples of com- mon uses of motion-picture films

25、are: negative, positive or print, intermediate, internegative, reversal, and leader. NOTE - The nomenclature system adopted several years ago for titles of American National Standards contains a reference to the perforation types used for 35-mm films. However, symbols for 16-mm, 8-mm type R, and 8-m

26、m type S perforation shapes were not included. The list below specifies the symbols used for identifying perforation shapes. The symbols differ from those previously used and Page 2 of 5 pages STDmSflPTE L84fl-ENGL 3998 m represent international agreement. It is anticipated that revisions of America

27、n National Standards on film dimen- sions will incorporate the new symbols in their titles and that these documents will specify the symbols for any new perforation shapes.
