Final film film requirements * All films should be dimensionally stable and uniform in thickness (0.004 inches recommended).
* Only one film is used for each color, and the color and category should be the same (example: black positive film).
* The dot on the film should be a hard dot.
* Do not use any camera or etching film.
* All opaque properties should be implemented on the non-paint layer of the film and should be minimized as much as possible.
* The bottom ash density of the film should not exceed 0.07.
* The maximum density of the film should not be less than 3.50.
* Gravure Printing requires the availability of a film model on the separation film.
Image orientation* All films should be viewed from the front. The emulsion side information should be above and the non-emulsion side should be below. The required film is negative or positive and should be determined by the publisher.
Registration Marks* Four central registration marks are required on a color printed film, approximately 1/2 inch outside of the text area on each color film. As long as color advertising printing is not a bleeding proof, the registration mark must be removed before the imposition. The removal of the registration marks required for the page group version should be performed by the printing staff.
* Both sides of the registration mark should be at least 1/4 inch long solid lines.
* The line width of each color should be exactly equal.
Multiple insertions* The number of proofs or color separations and film types should be provided at the request of the publisher.
* The correct process control elements should be used on the final film to ensure that all proofs are the correct copy of the dominant document or film. Like the UGRA plate control wedge bar and the RIT micro line resolution measurement standard, all this is done.
The creation and exchange of electronic documents:
With the use of film in the industry at the same time as the increase in the means of electronic document exchange, then the format of these documents must be easily read and written by many systems. Moreover, these files must contain data that ultimately produces a film or media that fits the SWOP specification. This goal can be to combine the image produced by the electronic document and the image provided by the film in the same printed form.
General requirements:
* If remote proofing is widely implemented and strictly controlled, a SWOP-approved proof must provide all electronic documents that are unrelated to the delivery process.
* The digital color bar should not be directly included in the body of the image. During all job transfers, the digital control bar should be included in the file but outside the text image. This color control strip should include 5%, 25%, 50%, 75%, and 95% of hue value patches for all primary colors to determine the accuracy of data transfer or data reduction.
* The transfer method (eg tape, removable disk, electronic transfer method) and file format used to exchange electronic documents should be accepted by all participants.
* Electronic files should include an electronic file or hardware backup file to indicate the number of jobs and their contents. Like the insertion order, capacity size, advertisement copy indication, etc., there should be GCA specification/agent communication exchange specification (SPACE) and DDAP e-commerce information exchange specification (DDAP DEBIES) applicable to publishers for communication.
* These documents should also include all SWOP's logical parameters (documents: UCR/GCR, gray balance, tick marks, image traps, etc.) for document preparation and final film. When multiple insertions are included, there may be a need to provide multiple sets of files, so check with the publisher.
* SWOP considers DDAP user requirements specifications for editability. There are a few changes that need to be made to this specification. They should be developed only for the direction of the advertising agency/advertiser, and they should be agreed with the publisher and the printer.
standard format:
* For the proofing process for the prediction results, the results of the assembly and output, the final prepress file should be defined using the ISO12639 standard, in line with the P1 TIFF/IF file format, in the form of a CMYK raster image file. communicate with. Typically, there is a need for final pages, continuous image and linework documents. In some cases, high-resolution continuous tone images are also needed.
* SWOP supports the work of the CGATS and ISO TC 130 Committee on the development of standard formats for the exchange of documents. As with other formats developed by the standards committee, SWOP will evaluate these formats and consider inclusion in the SWOP specification. Currently, the ANSI TIFF/IT P1 format is the only format recommended by the DDAP Association, and SWOP has used it for the present work.
Other formats:
* As long as other file formats must be used to communicate the process, the GCA Electronic Machinery Specification (EMS Second Edition) 118-1993 or equivalent may be used in all inter-organizational agreements. This document is especially for the use of dedicated desktop applications or closed electronic prepress system (CEPS) files, involving various variations of other file types (like: EPS, PICT or PDF files) Format) provides guidance. One exception to EMS is that SWOP-compatible digital files are not allowed to be displayed on the screen.
* Data compression will only be used when the sender and receiver agree to this method and use compressed files. It is the responsibility of the transmitter to ensure that publishers and printers understand that the compressed format is used and that there are ways to decompress it. Only lossless compression can be used: the compression method requires data with a rate of change of 0%.
Proofing* All colors of proofing should be accurately registered.
* Color proofs should be offset proofs made according to the SWOP specification or off-line proofs produced according to the manufacturer's SWOP Application Data Sheet.
* Samples will change over time. Therefore, the proof should be dated, and if it is known that its appearance has changed, it should not be used (for example, exposure in the sun will affect the color accuracy of the proof effect). (To be continued)
