[0003] Lamination is an important process for the surface processing of printed matter. For a book, the cover has the highest quality requirements; in actual production, the color of printed matter after lamination will have a large difference, and the color of printed matter before and after lamination will be different. The difficulties brought about by mass production are also problems that the industry has been troubled with

Embodiment 1

[0068] 1. Measurement of color gamut guide table

[0069] After the electronic document is printed, when the film is produced, the color difference before and after the film is relatively large. Print electronic documents including pictures and IT8 color gamut guide table through the machine, print several copies (usually 100 copies), calibrate the CTP curve and adjust the color of the printed sheet through the G7 method, so that the color of one of the several copies after lamination matches ISO standard digital manuscript (at this time the main data of the color gamut guide table conforms to the ISO standard), take several uncoated sheets at this time, and use the X-Rite series of automatic measuring instruments, such as Eye-one iSis to conduct the color gamut guide table Data measurement to get the data of the current color gamut guide table.

[0070] What needs to be explained is:

[0071] 1) The color of the coated printed sheet matches the ISO standard digital draft, w...

Abstract

The invention relates to the field of printing, in particular to a color management method and device for laminated printed products. The method mainly comprises steps as follows: laminated sheets of a color gamut guide table are measured to meet the ISO (international standard organization) standard, non-laminated sheets are measured at the moment, an ICC feature file is produced according to data, difference conversion calculation is performed on the ICC feature file and an ICC feature file meeting the ISO standard, a difference data packet is obtained, a second electronic document obtained through difference data packet conversion is used for table printing color treatment, printed product sheets of a second numerical draft are obtained, and the printed product sheets with the color meeting the ISO standard are subjected to laminating treatment, so that the problems that repeated adjustment is required due to color change before and after lamination and the accuracy is not high are solved. Compared with traditional methods, the method has the advantages that color adjustment is performed before lamination, the difference data packet is calculated, the problem of color change before and after lamination is solved, the production efficiency is improved, and the stability is higher.

Description

technical field [0001] The invention relates to the field of printing, in particular to a method and device for color management of film-coated printed matter. Background technique [0002] Laminating, also known as "overplastic", "mounting glue", "film sticking", etc., refers to the use of transparent plastic film to apply heat and pressure to the surface of printed matter to protect and increase gloss. Laminating film has been widely used for surface binding and protection of book covers, picture albums, commemorative albums, postcards, product brochures, calendars and maps. At present, common film-coated packaging products include cartons, cartons, handbags, fertilizer bags, seed bags, self-adhesive labels, etc. [0003] Lamination is an important process for surface processing of printed matter. For a book, the cover has the highest quality requirements; in actual production, the color of printed matter after lamination will have a large difference, and the color of pri...
